Hey folks, 

After Jared's presentation last night, there was some discussion of a group order of Bus pirates, or a group order of boards and components. I had to leave... Did anything more happen with that? After getting a better understanding of what the Bus Pirate is, I'm really interested in getting one. 

Who's interested in doing a group order for components?
Who's interested in just getting a pre-built one?

thanks

Yes,
We had you paged so we could give you a dorkboard to test on. But you
were gone....

It would be nice if we could get this american manufactured if we are
going to group it.

Don, I think the only option there is SparkFun (who claims in their product listing to build them in-house). Adafruit also has Bus Pirates, but their copy seems to suggest they're reselling units from SeeedStudio (in China). I'd e-mail Adafruit, but I'm too lazy... :-)

I'm a bit nervous about the SparkFun version, because it looks like either an old revision or a redesign. Based on several past, bad experiences with SparkFun-designed devices, I'd rather get one somewhere else.

I would second that Re: the sparkfun version. They also reversed the connector, so that the color codes are different from the Seeed Studio version. After having used the sparkfun version for some time, I finally bought a real Bus Pirate, and I feel much better about it. :)

The Adafruit version is definitely the original Bus Pirate, which means Ian Lesnet (the Bus Pirate creator) is getting paid for his work (always a good thing!)

There is a Dangerous Prototypes page that outlines the differences between the recent models:

I'm all for doing a group order of components and reflowing them ourselves. I actually have a Bus Pirate PCB I got from Laen a while back. For the new version, I think the cost for 3 boards would be ~$10. 

I'll throw in a +1 for the creator getting paid for his hard work, but I'm more interested in reflowing the board myself.

I already have a Bus Pirate so perhaps I shouldn't comment here since I wouldn't participate in a group order. But I do like the work that Ian Lesnet and the DangeroutPrototypes.com crew are doing in developing the Bus Pirate and other neat OSHW stuff. So I would definitely like to see him get some money out of a group order. They do a lot of support of the Bus Pirate (including developing the firmware that you will need if you build your own). I'm all for reflowing boards and such, but if it comes down to a choice between building/reflowing your own or buying from SeeedStudios and knowing that DangerousPrototypes gets some money, I'd choose the buy from China (Seeed) option in this case. Or maybe build your own but kick some money Ian's way?
I am pretty sure that SparkFun do also give Ian a cut from sales of their version of the Bus Pirate. But I've heard that people have had problems with outdated firmware on the SparkFun version as well as the reversed connector issue already mentioned. So that might not be the best approach.

I am in for two if we go this route. The fab stays in the states and the creator gets some dough.

I like it.

If we go v4, I'd be in for one (maybe two).

First, let me say that Jared did an extremely good job in his presentation.  He sold a big portion of the crowd on getting a Bus Pirate.

Ian of Danerous Prototypes seems very OK with folks making his design.  I'd rank him as one of the most open of the OSH designers.  It would be a nice gesture to send him some $ or perhaps give him a "Dorkbotpdx" version of Bus Pirate.

Dangerous Prototypes has really good documentation.  He even provides a link to Mouser for all of the parts, so it was easy to get pricing.

For quantity one:
V 3.5 is  $9.92 parts cost
V 4.0 is $15.25 parts cost
PCB from @laen would be $5.78 each ($17.35 / 3)

If we order >10, the cost will likely go down a dollar or so per unit.  The savings could be our donation to Ian (or be used to finance a board for him).
So the math says we can get a bag of parts at half the cost of a finished, tested unit from Seeed.  Low volume local contract manufacturing would increase the cost far above Seeed Studios price.

V 3.5 vs V 4.0 summary:
  • V 4.0 uses a PIC with built-in USB instead of FTDI USB-serial, so it can transfer data about 10X faster. 
  • V 4.0 PIC24FJ256 has a lot more Flash and RAM space than the PIC24FJ64 on the V 3.5
  • V 4.0 has a 12 pin header to support openOCD JTAG, V 3.5 has 10 pins (pin order is completely different)
V 4.0 a few other minor new features.  Check the link.http://dangerousprototypes.com/docs/Bus_Pirate_v4_vs_v3_comparison

Translate from: English
Type text or a website address or translate a document.
I'd prefer the V4.0 as it will eventually have features that the V3.5 won't be able to duplicate.

We could do a mixed build of 3.5 and 4.0 if there are folks with a strong preference for both.


Proposal:  We group manufacture this ourselves.

I would be willing to coordinate a group order for the parts, and send in the PCB order to @laen. (US fabs!)

Perhaps someone with Eagle CAD could do a custom Dorkbotpdx silk screen. (or we could have a contest...)

Could someone (with access to ADX perhaps) make us a solder stencil?

Can I talk Jim and/or Scott into volunteering to organize a reflow party for everyone to gather to build their boards?

We also need someone with a PIC programmer.

I’m in for one v4.0 board if we go with this approach.

 

I would also donate a couple mylar stencils cut on my Silhouette Cameo cutter.  I haven’t seen one close up, but doesn’t look like there’s anything less than 0.5mm pitch, correct?  Shouldn’t be a problem.

If you're all okay waiting for the medium run (which would be back in about a month from now), I'll make the PCBs for free.  I just need to know how many to make.

I'd be willing to wait and then I would be in for one V4. I'd also be happy to help conduct a "build party", maybe even in conjunction with another SMD workshop if we can find a place to do it (and under the condition that we send some money to DangerousPrototypes). If we get the boards for free, I'd also vote for being more generous to the developer. Only seems fair. And maybe we could video some of it and send it to DangerousPrototypes. They might enjoy it and perhaps use it on their site.

We're up above 10. Maybe we should set a cutoff date and a post up on dorkbotpdx.org? I'd be interested in a few blank PCBs for the future as well.

I can bring my hotplate too (Though I'm not available on Sundays)

I'm writing down your names.

@laen says the gerbers have to be in his hands by February 10th.

Should I assume PIC programmers will be no problem and will arrive at the build party? (I do not have one)

Aaron, could you make the announcement on dorkbotpdx? 

Would we take "orders" from folks outside PDX that see that announcement?  I think the logistics could be tough (taking payments, stuffing envelopes), and I am not entirely comfortable competing with the usual channels for Bus Pirate beyond it being a project for Dorkbotpdx.  Maybe if it was limited to blank PCB's for DIY'ers that source their own parts, and we pay @laen for those boards and take a bit for Ian as well, and someone else volunteers to handle the mailing, and... yeah.  Too much trouble and not enough time to plan it.

The silkscreen changes are still an open. Technically I can do it, but I'm artistically challenged.  I was thinking of some sort of design contest, but there isn't a lot of time.

Regarding ribbon cables - Mouser has 1ft lengths of Rainbow ribbons for $.53 each. The Bus Pirate v4 is a 12 pin connector, and 12-wire ribbons cables are apparently uncommon at mouser. I priced the 14-wire

The clips are bit more spendy, unless I'm missing an obvious option - they're about $1.50 each, and available in a wide variety of colors.

I'm in for a v4 board as well, and I really like the idea of having
some sort of custom artwork on the board.

I'm also in for a donation to Ian and maybe it's too much, but I think
it would be cool to send him a board as well as some cash, assuming we
have some sort of artwork on it - I imagine he's got plenty of "stock"
bus pirates around.

Brad.

PS Hopefully I'll have my hotplate working as well for use.

    Ditto on a v4 -- and this would be a great opportunity for an SMD class since I couldn't get in the first one.

    Happy to donate to the developer since I was planning on buying one anyway.

    Aaron and all
    I found 12-pin shrouded headers, but not 12-pin IDC sockets to mate to them.  I don't think they even exist.

    We could use 14-pin headers and cut two pins off so the header will insert in the board, and ribbons cable will plug in nicely.  Or use 12 pin headers without a shroud. Or (dare I say it) add two more holes to the PCB.

    Test hooks are available from places like dealextreme http://www.dealextreme.com/p/electrical-wire-testing-hooks-10-pack-8391 for $2.30/10, but only in black at dealextreme.

    This is a bit of an unexpected design issue with the V4. See this thread:
    http://dangerousprototypes.com/forum/viewtopic.php?f=4&t=3482
    Apparently 12 pin keyed IDC plugs for the shrouded header are pretty hard to find. Who knew?

    Yeah, it might be a good idea to just go with 2x7 pin hardware and add two more holes. Grounding them would probably be a good idea. But this would end up being incompatible with any DP probe sets.

    I'd caution against going with DealExtreme or other cheap Chinese test hooks. The ones from SeeedStudio are probably pretty typical of that ilk and they don't get very good reviews. I bought a set and don't find they stay hooked on very well. Unless rock bottom price is the overriding constraint, I'd suggest going with better quality. Pomona hooks (for example) are quite a bit more expensive but way, way less frustrating to use. I think the best thing is to have individual female pin headers on the ends. That way, you can either plug the probe wires into pin headers on your target or attach test clips (which are available with male pin headers).

    See more below.V 4.0 has a 12 pin header to support openOCD JTAG, V 3.5

    has 10 pins (pin order is completely different)

    I'm willing to do this. Where's the link to the design files? I don't
    have time to search for it.

    If we have a decision on the JTAG pin count, I'll fix it also.

    I'll be delighted to do this. I'm not sure trying to combine it with
    another class is a good plan, however. Maybe cramming in too much in one
    time slot?

    Also, I have plenty of paste and can set up a stenciling station.

    I bought some of the hooks from Deal Extreme and a set from Seeed... Don't waste your money on either. They break, solder connections are tempermental at best, and you can't make anything cheaper.  Trust me (and Scott) it is worth it to get a decent set of test hooks.  Maybe we can get a bulk discount on some quality ones...

    I think the 14 pin suggestion along with a dorkbot logo makes sense.
    People can populate a 12 pin if they like.

    So this is probably stupid, but I don't suppose 16 pin connectors are available?

    I was thinking you could put a pair of grounds on each end and still
    be compatible with a 12 pin cable as well.

    Just a thought,

    And maybe this is even a worse suggestion (especially given that Laen
    mentioned doing the PCB's for free) but what about grabbing the Eagle
    files and making _slightly_ larger version that could be soldered by
    hand?

    I mean I looked at the Sparkfun version (v3.6) and I think if we
    replaced the 0402 parts with 0603 (or ideally 0805) it would be fairly
    simple to build the board without a hot-plate.

    Heck, it looks like you could almost keep the same board size and just
    move things around a bit (of course I didn't look at v4).

    Might make bare PCBs a bit more useful for the community. Or maybe
    everybody that could hand solder this already has a hotplate?

    I'm just trying to think beyond the initial order.

    Brad.

    Been following the discussion, and I thought I would chime in. The hardware available from the Dangerous Prototypes website doesn't appear to use anything smaller than 0603s for the passives, although it does include some quad resistor network packages, and the PIC is in 0.5 mm pitch QFP. You can SVN checkout the files at:


    The latest version appears to be 4b (all of the v4 versions are mixed in this directory). There are gerbers and Eagle files.

    One suggested improvement for hand soldering/placement would be footprints with better silkscreens for several of the components (passives, transistors, maybe a couple of others).

    I guess that's what I get for only looking at Sparkfun - I was lazy,
    sorry. Mea cupa.

    Phillip's post expressed my idea better than my post really. I do
    know time is short for any sort of changes though.

    I would caution against making many design changes to a board which goes straight into a large group order. Maybe it is just me, but I'd hate to end up with a big pile of scrap boards. Some silk screen editing and adding a couple more holes for the connector is about as far as it should go I think.

    I also agree with Scott.  Keep changes to a minimum when ordering 30+ PCBs.  Actually, I would prefer not to make ANY changes whatsoever before a production run (but when has that ever happened).  But 2 pins and the silk screen seems minor enough.  What could go wrong?

    Well, I'll tell you one thing that has already gone wrong.  One of the voltage regulators is end-of-life.  There should be compatible parts available.  I'll search today and send the PN's out for a double check by the group.

    We have to keep in mind we're ordering a Beta-ish product as it is. It's enumerated on the site several times that the v4 is not as stable as v3

    Fewer changes = less potential problems in the future. That said, a couple of ground pins isn't going to hurt anyone (Famous last words...)

    It might be possible to contribute to this project by building in a couple of batches and making a few improvements each time. 

    This could also be a good way to simply triple the amount of work involved.

    Here is the link to the SVN.

    What I want is version 4c, the brd file, the sch file, and the xls parts list. Problem is that I don't have much experience with SVN and I have had no success in checking the files out. Is there an SVN guru out there that could do this and just send me the three files? That would be a great help.

    I'm also assuming I can edit these in Eagle 5.9. Can anyone confirm or deny?

    Thanks! The sooner I get these the sooner I can make the changes.

    I can help, if a build party gets set up, but I don't have the money
    to get one of my own right now, as I said before. I have a couple or
    three extra (non adjustable, sadly) soldering irons laying around if
    they're needed. (If I can find them in my piles of moving boxes and
    stuff.)

    OK Dorkies - Here's the status:

    - I'm working with Version 4.1 of the Bus Pirate.
    - You'll be able to put on either a 14 pin or 12 pin header.
    - The Logo will have mention of Seeed Studio removed to be replaced by
    DorkbotPDX.

    I still have to run Laen's DRC to make sure things are OK. I'll post the
    board for group review when it's ready. (Is that possible? Can the files
    be posted to the DorkbotPDX site?)

    One further thing. I'd like to add the DorkbotPDX logo to the back of
    the board. But I need help.

    Only one color is available, so the nifty shadow is a problem. Is there
    an "Arty Type" (you know who you are) out there that can send me a
    suitable version of the DorkbotPDX logo using only one color (that
    should be black)? If someone could do that, I'll put it on the back of
    the board (maybe front also if there's room). A large size image with
    nice detail would be best. Have a look at the Instructable below for
    some details on what I'll need.

    TIA for any help!

    done and you can put in the Copper Shadow.

    I expect I'll get some good, useful input on the art work and I really
    appreciate it!

    But what I most want is for everyone to say Amen to version 4.1. I
    notice some routing and placement differences from 4.0c and I want to be
    sure this is the version we all want. Is 4.1 a "known good" version or
    is hot and steamy?

    Jim,

    Sure, as long as somebody can break up the logo into separate monochrome images for the capacitor and the shadow.
    When would be able to send over the board? I'm using Eagle v5.10, BTW.

    The process is the same for both silk and copper, so I might as well do both.
    But first, is there a big enough clear area for the logo? I don't want to disrupt the ground plane with the shadow unless there's an appropriate area out of the way of any important current-return paths.
    I didn't see a quick way to get at the eagle files from their google repository.

    4.1 may be a bit steamy.

    Differences I found in a side-by-side visual look:

    4.0c -> 4.1
    board size  60x37 -> 63.5x36.8
    mounting holes in corners -> tooling holes.  Centers have also moved slightly
    IC2 (4066)  TSSOP -> SO14 package (bigger and slightly easier to solder)
    LEDs -> slightly closer to board edge
    PCB rounded corners -> square corners
    Reset button 1mm from IO connector (2x6 header) -> Reset button 4mm from IO connector (more room for fingers)
    IO Connector 7.2mm from right edge -> 6.3mm from edge
    ICSP connector 3.5mm from bottom edge -> 2.5mm from bottom edge
    USB connector -> footprint edited, pads shortened (less friendly to hand soldering). Also moved slightly closer to board edge.

    Silk screen has large logo on back, helpful IO pin functions on top and bottom -> logo gone, pin functions gone from top.

    Many small changes to part locations.  Some random ground plane via's removed.

    No significant change to schematics.


    Net: 4.1 has changes that may make it a hassle to fit in some 4.0x cases.  4.1 has less help on silkscreen for users. They should function identically.

    By coincidence we're also working on a group Bus Pirate build at Jigsaw Seattle.  We decided to clone off of 4.0c, re-layout the board for 5x5cm and add a few breakouts/mods.  We also substituted a few minor parts and footprints.  I was tempted to swap out the regs for SOT-223s or switchers but ultimately that didn't happen.  I'm curious what regs you end up choosing.  Part of the reason we did the redesign was to have members practice with Eagle.  It's definitely not the greatest layout as it was half autorouted and somewhat rushed, but it should work.

    Here's the link to our design. We haven't tested it at all as we're still waiting on the board to come back from China so use at your own risk :)

    Jim,
    Scratch all that below.

    4.0c is the steamy version.

    4.0 is sold by Seeed.

    4.1 the only change is they added CC-BY-SA to the silk screen.  Stick with 4.1.

    We plan to stick *very* close to 4.1. Thanks for sharing your design however. Nice to see a similar idea.

    As far as your boards go, you might check out the DorkbotPDX board order. Anyone can participate and the cost includes postage.

    I haven't received anything yet, Monty. I'll send you the files I'm
    working on so you can look at the ground plane on the bottom. I've
    already sprinkled "DorkbotPDX" in a couple of places, but I think
    there's room for the logo on the bottom lower left side (viewed from the
    top side).

    Sorry, Cameron, but this BusPirate thing involves about 30 DorkbotPDX
    members; we're trying to do it quickly, and no one has set up a mailing
    list. It's fine if you want to interleave another topic, but we kinda
    need to blabber over this one.

    That said, are there any PIC experts that know if the ICSP header needs
    to be special? The one on the BusPirate4.1 design has the 5 pins offset
    from each other. Is that necessary or would a standard straight
    connector be preferred?

    Needless to say, I need to know this sooner rather than later.

    The pickit2 and pickit3 have a 6 (.1") pin female header and in general the 6th pin is not used.
    The programmer will need a bit of clearance if you mount them vertically on the other hand I usually just make a cable.
    There is a pretty good picture and a profile on the pickit1 doc attached.

    This has been a rather epic thread. Let's see what it looks like over time.

    I have a favorite visualization that I apply to conversations. Each participant is represented by a string. Each character of the string is one hour. Activity in that hour creates a blip. Inactivity leaves dots (or comma at midnight). Here is this thread from Wednesday through Saturday, up to, but not including this post.

    If we are still talking about a target price around $15 (plus or

    Here is my calculus on kit pricing.

    The cost of the parts per kit (including connectors and 12-inch ribbon cable) comes very close to $15 with the volume discount at 30 kits.  I should bump the quantities up some to allow for "losses in manufacturing", plus shipping from Mouser. 

    So $16 for the kit, assuming cash on delivery.

    Add $2.00 for shipping (and you will have to pay via Paypal) if you are not going to pick up the kit at the build party(s) or at a DorkbotPDX meeting "soon" after it is available.

    Add 2.9% + $0.30 if you pay via Paypal. Note that the parts order is going to be over $500, so prepay will be appreciated.  I should be available to take prepayments at the next DorkbotPDX Monday meeting.

    Doing the math:

    $16.75 if you prepay via paypal and will get a kit at DorkbotPDX or attend the build party.

    $18.80 Shipped and paid via Paypal.

    Don't forget to add a dollar or two for Ian (Dangerous Prototypes) if you want to support his development of the Bus Pirate.  Whatever cash I have left over at the end is going to him.

    Also, everyone is going to owe @laen a beer for the PCBs.  (or donate ~$3 to him)

    FWIW, I've tried to do "exact pricing, 'see, I'm not even making a
    penny!'" on things before, and it's really not worth it. If you work
    out $18.80 shipped and paid via PayPal (boo!) then just charge $20.
    Hell, charge $20 for self-pick-up and $25 for shipped.

    That way, you don't have to obsess over it when DigiKey calculates an
    extra pound and shipping is $1 more, and you don't have to dig into your
    own pocket to cover the dollar-here, dollar-there incidentals. If you
    come out ahead (you probably won't come out _much_ ahead, if any) you
    can send the excess to the donation you were asking everybody to make.

    The geek obsession with the evils of making a profit is one of the
    things that keeps many of us stuck in McJobs that we can't afford to
    leave because we need the health insurance.

    Ooo, this looks like a great opportunity to upgrade from my trusty black v2go..

    definiately interested in 1 of them, might not be able to make it to
    the flow party (hope I can, but can't count on it, especially when I
    don't know when it will be) -- does that estimated shipping cost
    include a cost for assembly too?

    now for a more blabber worthy question:

    as one of the people that ended up with a v2go with a bootloader but
    no firmware, what do you all think would be an appropriate post
    manufacture test?

    (persoanlly I'd be happy with just being able to see it through the
    terminal, as that's more than my v2go could do when I got it..)

    DorkbotPDX Bus Pirate kit orders instructions

    1. Payment method
    2. Prices
    3. Description of what you get
    4. What you don't get
    5. Estimated timing


    * Payment:

    Please pre-pay with Paypal if you can. 
    My paypal address is nikk...@yahoo.com.

    Cash will be accepted at any DorkbotPDX meetings when I am there, for example on 2/27, and at the build party. I will not be at the Dorkbot meeting on 2/13.

    Worst case, mail me a check.  Email me direct for my address.

    * Prices:


    ** Best deal and you get to learn-by-doing SMD assembly :
    $16 Join us at the DorkbotPDS Bus Pirate Build Party to help build boards and leave with your board assembled and programmed.
    note that the party is not a structured class.

    If you prepay and someone agrees to do the assembly for you and deliver the board to you, email me with the name of your representative so I can track who is authorized to get your board.

    You can just pick up your kit at the build party and not assemble it, but what is the fun in that?

    ** Unable to make it to the build party:
    $18 Pick up your kit of parts at the DorkbotPDX meeting after the build party.

    ** Shipped to Out of Towners (and local folks too shy to attend DorkbotPDX):
    $22 Get your kit of parts mailed to you. 

    Email me your address if I don't already have it, or put your address in the comments with your paypal payment.
     
    * What you get:
    The kit includes all the parts, mostly SMD (including an unprogrammed 64-pin TQFP PIC24), to build a Bus Pirate v4c and a special edition, purple, made in the USA, DorkbotPDX Bus Pirate PCB v4cD donated by @laen.  The board design has been modified to accept a more easily available 14-pin header, which is included in the kit.  If you want a 12-pin header like the original v4c, you will have to supply your own.

    You also get a 14-pin IDC socket and 12 inches of ribbon cable.

    * What you don't get:
    The PIC24JF256 MCU does not come pre-programmed with the Bus Pirate loader or application code. 
    You will need to have access to a PICKIT2 or PICKIT3 to program it. Attend the build party or find someone at a Dorkbot meeting that has one and willing to program your assembled board.
    Another option is to follow these instructions to build a temporary programmer out of an ATmega8 (or similar AVR): http://dangerousprototypes.com/2011/12/23/avr-based-pic24fj-programmer-for-uploading-bus-pirate-firmware/

    You don't get any test clips for your ribbon cable.  I couldn't find a source of good quality test clips with a volume discount. 
    Digikey has some decent sets of ten rainbow colored test clips:
    micro J-hooks http://search.digikey.com/us/en/products/XM-S/461-1006-ND/528227
    SMT grabbers http://search.digikey.com/us/en/products/XKM-S/461-1012-ND/528233

    You probably don't get to make a donation through me to Ian.  He told Scott he can't be convinced to take any money from us.  He says that the group interest is thanks enough.  But if you come to the Dorkbot Bus Pirate Build Party, you just might get a chance to thank Ian in person! (Easter egg for reading down this far, but his attendance is not guaranteed)

    I will say it again, the PIC24FJ256 does not come pre-programmed in the kit.  Attend the build party or plan accordingly.

    * Timing

    Pending Jim and Scott finding a venue and at least one of them having the weekend free, the DorkbotPDX Bus Pirate Build Party will be the second weekend in March. 

    Kits will be available at the DorkbotPDX meeting held every other Monday at Backspace following the build party.  Hopefully that will be March 12th. 

    The  Dorkbot meeting on March 26th is during Spring Break, so I can't guarantee I will be at Dorkbot that week. 

    If you don't think you can make the build party nor the DorkbotPDX meeting on the first DorkbotPDX meeting after the build party, you should consider paying for the shipped option to avoid a possible long wait for your board.

    Kits will be shipped out sometime during the week after the build party.

    Any kits not paid for by the DorkbotPDX meeting after the build party are subject to being sold to someone else.

    You should be able to program the BP PIC24 with another BP...


    I haven't tried it personally though.

    Hi-

    I am unable to attend the build party :-(( , but would be willing to pay a few bucks to someone to do my single kit for me. I will prepay the parts. NP if nobody can do it, I will just do it myself later, but with my current schedule....

    Private me to arrange, if anyone is willing to do this-

    Regards-
    Doug

    A little additional status. I will be sending out email confirmations tonight to everyone who I've got on my list to attend the build party. If there is anyone who still wants to sign up, there are a few slots left so please let me know ASAP (please email me offlist).
    Also, if you think you signed up and you don't get an email from me tonight, please get in touch with me either by email tomorrow or catch me at the Monday night meeting and I'll sort it out.

    Great big thanks to Greg and Scott and a bunch of others for equipment, organizing, and assisting with the bus pirate build party today.. I think it was a huge success in no small part to the volunteers that made it happen!

    Scott, Monty, and Jim were great volunteers to work with.  They did a lot of behind the scenes work preparing for the build party. They provided most of the equipment, a lot of supplies, plus their time and expertise to make the build party itself a success.

    The members of Dorkbotpdx that came to the build party also played no small part in making the day successful and less stressful than it could have been.  You guys were patient and respectful of each other and the volunteers, even when things got blocked up or went less than 100% smooth.  I know a lot of you hadn't worked with SMT before, but everyone did great with very little instruction. 

    29 out of 30 boards went home working. 

    I'm making a note here:
    HUGE SUCCESS

    I have to add my voice here. From a participant perspective, I have to say this was an awesome experience. Despite some major user error, I too went home with a working board. Everyone went way above and beyond to help (including Ward with his extensive rework skill).

    THANKS!

    Bob
