Vacuum pen and stencil8 tooling block for the space

[Nick Johnson]

I've contributed a vacuum pen with tips and a stencil8 tooling block in polycarbonate to the space. They're on one of the workbenches.

I presume this is a welcome contribution; if it's not, let me know and I'll remove them.

-Nick

[Paddy Duncan]

I’ve put them all in a blue linbin on the shelves adjacent to the electronics area, they were beginning to scatter already..

Thanks Nick

Paddy

Really cool. Thanks. They'll go nicely with our new PCB reflow oven which arrives this week... :-)

I was hoping to run a tutorial on the whole process, but we'll need a sample PCB. One that uses a stencil would  be ideal.

I've got PCBs and stencils: I wouldn't mind using one of those, although I'd prefer not to sacrifice components :-/

Yes, we need a sample PCB that's simple and cheap to assemble.

-Nick

[Jon Russell]

I'll scan in the chinglish instructions (if it comes with any) and upload them to the wiki.

I'm hoping it won't need training. If you can use your oven at home you'll be good to go ... :-)

You can use one of my boards if you want :P

It is very straightforward. For those following along at home:

- The default reflow profile is fine for leaded solder paste

- The very perimeter of the oven, especially the front, may result in some unreflowed parts; stick to the center. Most of the area is usable, though.

- When the oven starts up, press F1 to get to the main menu

- When it starts beeping continuously, it's done. Turn it off at the back.

Oh, and don't put anything flammable under it or within about 10cm. :)

We were donated a load of facedancer pcb's:

http://goodfet.sourceforge.net/hardware/facedancer11/

We'd need to get the components for them.

We've got some goodfets as well, Paul Dart ordered the components to
populate them, but not sure how that ended?

I ordered the parts and they arrived. I have enough parts for the 8 or so boards we have.

For sale at cost (as per that wiki page) as price breaks made it worth while to buy parts for all.

Thanks,
Paul

We should be getting a reflow oven in the next week or so iiuc.

Curiously enough i bought a spaceorb off of ebay on friday, it should turn
up this week, so if you've got a spare board i'd like one :)

Ha!  Sure thing; I almost never find anyone who's even heard of them.   I haven't actually tested this version of the board, but the previous ones have worked like a champ.  I'll set one aside for you :)

I would really like to learn how to do reflow, happy to populate some boards

for you and Jasper and could populate a GoodFet for someone/ the space (I have

some bricked hardware I want to un-brick, apparently the bus pirate can

be used for this, but I don't want to bother Jasper . . .).

depending on whats other tools you need, probably more than you would

want to talk to at once.  for some reason I have it in mind that 8

people is the most you want to do a workshop "with".

there are a few guest laptops running linux, a tinyxp install could be

there is a:

USB microscope connected to tesla and works (with "cheese", whatever

happened to xawtv?) out of the box on lorenz (one of the guest laptops).

I'm expecting some prototypes of version 2 of my Re:load board, which is surface mount and very straightforward. If anyone wants to pay for materials costs I'll happily bring them in for an SMT soldering lesson.

[Tim Storey]

Hi Nick,

When would be a good time for you ? I'd happily pay for materials...

\t

[Nick Johnson]

Hi Tim,

I just ordered the PCBs, so it'll be a week until I have them at least. I'll update the list when I have an ETA.

-Nick

[Vic Putz]

> Vic:  when are you available?

*Almost* at the drop of a hat, pending verification of materials.  The boards came in today and I'm going to populate a couple this weekend to make sure the new design works and make the new pogo fixtures.   I'll plan on making a bunch of "stencil holders" (ie cut apart some cutting boards and tape stuff on them).  Some handouts wouldn't go amiss either.  After this weekend I should be ready to go.

Flashing would work from linux with AVRdude, but a Windows install with Google Earth or something might be nice to demo the result; I could bring a controller and people could fly around with the board they made, which would be good fun (it would probably work in linux too since it represents it as a 6-axis 16-button USB HID device, but I haven't tested it).  Or an old Left 4 Dead install; always good to make hardware that kills zombies.

[Vic Putz]

can they be used instead of a teensy?

Paul and I had "religious differences" on a forum early in the Teensy development (we've never met or anything--I wanted him to open-source the Teensy bootloader and he refused) and so I refused to use it, which was pretty immature of me, but at least I learned how to build my own board this way.  (I made an Arduino Uno shield to start with (http://goo.gl/kGCZJ) but V-USB gave me fits so thus the AtMega32u4 solution).  It uses the same chip as the Arduino Leonardo and a slightly modified bootloader, so basically it's a Leo with an RS232 DB9 port acting as a 6-axis 16-button joystick/mouse/keyboard; you can use the Arduino environment to handle the remapping of the device.

 for some reason I have it in mind that 8
people is the most you want to do a workshop "with".

I put together four stencil boards, but after wrestling with a few builds today I'm lightly nervous about a class simply because the micro-USB connector I chose... sucks :)  It's very difficult to get right and hard to fix when it goes wrong (tends to bridge "under the connector").  Still, worth a try as long as people are willing to be patient.  And if anyone has found a SMD micro-USB connector that's easy to use, man, I'd appreciate the news!

ace. I can't commit to anything* . . at least till

put up a doodle to see if we can optimise (if thats OK . .?) unless

started another subject for USB connector advice . . .

sounds nicely "challenging" to me . . . you'd test it for continuity
then . . . you'd have to use a heat gun to remove and start again?
or could you "bake" that component first and put that edge in a
colder area of the oven/plate and do the less problematic pieces?

or far faster/ riskier/ pragmatic: whats the chance of blowing up
a usb port/ component? old pcs are (sadly. . .) disposable . . .

In general I think surface mount connectors are *hugely* over used, and
the smaller the worse the problem . .

(i've got a CCCamp badge with a bust micro usb, the tracks ripped off
with it* ;/)

sure its nice to have an ultra slim device, but from a design/
repairability/ robustness perspective they suck. recently I've been
volunteering/ "partying" a lot with:
http://therestartproject.org/

and it seems chunky as possible and well mounted connectors on fly-leads
are best.

is their room inside your orby-whatchamacallit ( ;P ) for your board?
I'd bet most people who wanted your board have a USB-A to something
that they could spare to cut in half . . .

How do I schedule it--just post the message and put it on the calendar, or what?

Heh--I thought the one you linked to didn't have legs that went below the bottom into the PCB, but maybe I didn't look closely enough.

At any rate, I think I'm ready to go for a small workshop of 6 (unfortunately the netbook I borrowed works OK for programming and test, but its USB disagrees with Linux after about 6-10 seconds of connectivity so aside from a few seconds of "jstest" there's not a great demo).  The board itself works great with other Linux boxes and Windows just fine, although OSX doesn't recognize it nicely (free board to whomever can figure that one out since I don't have a mac).  If someone wants to bring a Linux or Windows laptop with something joysticky for demo (the classic 6dof sim is Descent, so D2X-Rebirth is one candidate) that'd be fun but unnecessary.  I even carted the hot plate and the Kettletron 9000 to the space so we won't disrupt the electronics workspace (plus it's fun to watch boards cook).

Now I just need a time slot and participants.  Somewhere between 18 Jun and 2 Jul I'm taking a short holiday, but some time 14-16 Jun would work (sewing is on 11am-5pm on the 15th though).  22nd might work as well.  What's the best way to schedule?
