What can we do to enhance the Ingenuity Fest Experience (Drinking and Music)
|Embedded Electronics Classes/Kits for Ingenuity||Sam Harmon||8/29/12 12:29 PM|
Ok, here is my "mostly readymade" submission of a plan for the Ingenuity kits:
This plan gets us:
A- a really quick & easy to put together thing that is cheap ($1.50 each in quantity, can sell for $2-$3, or just in exchange for a donation or something)
B- An "Arduino Enough" thing that hopefully keeps us in the spirit and close enough to the letter of what we're supposed to be doing. If no one buys them, we'll have a bunch of extra Arduinos to do workshops and crazy stuff with in the future…
Also: If people really want a morse code blinky thing: http://brainwagon.org/2009/11/14/another-try-at-an-arduino-based-morse-beacon/ - which will blink the Diavolino's built-in LED.
C- Some additional tools so people can put these together about a dozen at a time...
Learn to Solder Skill Badge Kit
250 for $375 (+ $5 shipping), ships in 1-2 business days from California (time to receive 1 week-10 days?)
TOTAL FROM MAKERSHED: $380
EMSL Diavolino (w/6&8pin header set)
email@example.com w/headers & 3AA battery holder ($937.50)
Adafruit FTDI Friend - Not really for us to sell, just so we can program the Diavolinos a few at a time, and maybe cope with one or two walking off...
10@$15 each ($150)
TOTAL FROM EMSL=$1087.50 (Free Shipping over $75, time to receive 1 week-10 days?)
Stahl Tools SSVT Soldering Station (we already have 6 of these already)
6@$15.98 = $95.88
60/40 solder, 1 lb
2@$23.49 = 46.98
TOTAL FROM PARTS EXPRESS: $162.69 (7.5% Ohio sales tax, free shipping, total time to receive 1-2 business days)
TOTAL COST: $1630.19, leaving us with about $170 for incidentals (AA batteries for the Diavolinos?, more tools? anything else?)
That's my thought, anyway.

I may be able to help with batteries to save you some money. Let me know what size and about how many and I'll let you know what I can donate.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Joe ODonnell||8/29/12 1:23 PM|
That's a good, reasonable list. It would be great to include 2 of these on it as well:
A $40 student oriented FPGA board that can be programmed with classic video games:
And can also be programmed to be a custom configured Arduino:

Makers' Alliance shouldn't have to pay sales tax. There a form you can fill out to give to the vendor. I can find it for you if you'd like.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Paul "Froggy" Schneider||8/29/12 1:25 PM|
This is probably a bit off topic, but I've become a huge fan of the MSP430 Launchpad boards as of late. Available assembled for under $5 with cable, two different MSPs and some other neat stuff.

The drawdio is a tone generator that makes noises as the user draws on paper using a pencil. I have not built or used one before, but there are numerous videos up on youtube that provide a good demonstration of what it is and what it does. I am all for doing more complicated and original kits and projects, but I feel like the time limit until ingenuity fest means that we should really be looking for a low risk, proven project such as this.
Benefits of the drawdio:
-excellent instructions already available on the internet
-open source schematic and PCB artwork in Eagle format
-involves both audio (noise from speaker) and visual arts (drawing)
-proven, low risk design
-inexpensive BOM (few bucks each in volume)
-easy to construct for soldering newbies (all thru hole components)
-entertaining for adults/children/inebriated adults alike
I put together a BOM with digikey and mouser part numbers, quantities, and estimated per-component prices assuming medium volume (~200), which is attached to this email. In order to purchase PCBs, someone will have to download the Eagle board file, install the free version of Eagle, and cut gerber files. I work with Malaysian PCB houses that can do either a 1 or 2 week turn with 2-day delivery.
An additional note - I forgot to include a AAA battery on the BOM.

Addendum to my previous plan, based on putting together one of my Diavolinos last night (they don't include IC sockets…)
737-ICS-328-T 28 pin IC socket 100@$0.14 = $14.00 (+$5 shipping) = $19.00, bringing the total up to $1650.
|Re: [makersalliance] Re: Embedded Electronics Classes/Kits for Ingenuity||Joe Gorse||8/30/12 6:47 PM|
How does changing the quantity to 50 affect the unit cost on the drawdio?
I would like to do a combination of Drawdio, the learn to solder badge kit, and Diavolinos on a lanyard for the Ingenuity Maker/Hacker Badge. I think this allows for a decent amount of flexibility and hackability, though we may be a bit light on sensors and interface hardware yet.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Joe Gorse||8/30/12 6:49 PM|
I really liked this idea until I found out that it needed the Papililio in addition to the LogicStart, making it around $90/unit. I am fond of FPGAs, though at this price we may be able to do better for the quantity or functionality in the FPGA world.
|Re: [makersalliance] Re: Embedded Electronics Classes/Kits for Ingenuity||Joe Logan||8/31/12 8:11 AM|
In quantity 50, your BOM cost is going to rise 20-25% since all this stuff is sourced from Digikey and Mouser. On the PCBs, you are looking at a minimum order or 100 sq inches. Assuming these guys are about .5 x 2 in, it works out to be a $200 minimum order, 1 wk turn, with a net of 100 PCBs.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Sam Harmon||8/31/12 9:40 AM|
I did some number crunching, and I think we can make 100 work. It goes over the funding by a little bit, but we'll be taking donations and whatnot, so I think it'll be ok.
Now we just need to get the funding secured from Ingenuity…
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Joe ODonnell||8/31/12 9:53 AM|
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Joe Gorse||9/2/12 11:28 AM|
As per the rough schedule plus a couple days, we have the written go-ahead for the $1800. Go ahead and pull the trigger on the orders we know we need. If unsure, confirm with Sam or I so we can track our progress and open tasks on the wiki.
Next steps are to prototype test in small quantities, come up with a plan to use those projects/components from our experience from playing with them Tuesday, and then place the large orders by Wednesday.
I have re-organized our Ingenuity-related wiki pages under the Ingenuity Festival page (look for Site Contents to the right and Child Pages below) and added Project Management page for convenience from prior content.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Joe Logan||9/4/12 8:18 AM|
What was the final verdict on the drawdio? Do you want me to order the PCBs? I will work on getting gerber files made this afternoon. It probably makes more sense for you to do the digikey/mouser order to avoid having to mess with reimbursements.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Joe Gorse||9/4/12 8:35 AM|
Tonight let's try to prototype/play with a working drawdio or two.
If anyone has the other kits, bring those as well. I would like to rough out what we can actually do with a physical lanyard and the kits we have in mind. Maybe there are some easy integrations which might be fun.
Orders go out tomorrow after we see how things work tonight and our ensuing plan.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Joe Logan||9/4/12 10:26 AM|
OK, so I guess it's on me to track down some components.
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Sam Harmon||9/5/12 1:06 PM|
All of the major kits & parts have been ordered. We are looking into maybe getting some additional add-ons and things for Arduino experimenters, and have not yet ordered from Parts Express (ground shipping is effectively next-day from them, so no hurry)
Otherwise, things we still need(that I can think of right now):
-Pencils (100) - we have a fair number at the space, but I'm not sure of the exact quantity
-all-metal Thumbtacks (100)
-small Zip ties (200)
-AAA batteries (100)
-AA batteries (about 150)
-laptops for programming them (need to just be able to run the Arduino IDE, so nothing too fancy is needed, probably just need one or two more- I'll have my netbook, and a friend is likely donating a netbook as well)
-Mini-USB cables (as many as we have computers for programming)
--Electret microphones (I have maybe 2-3 around right now)
--additional LEDs (I have many various ones around)
--photocells (I probably have some somewhere)
-A cashbox of some sort
-Some sort of bucket for donations (perhaps a plastic carboy?)
-A few hundred signable waivers
-Some sheets with information about the group?
-Updated web page?
-New business card design (deadline is this Friday!)
-Help setting up on Friday the 14th?
-Lots of volunteers to help during the festival
-some more hand tools for each soldering station?
Anything else I'm missing?
|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Damon D Ramsey||9/6/12 4:29 AM|
I have the following covered:
- help with Friday setup
- help with info and security on Friday & Sunday (have a pre-existing commitment on Saturday)
- donation bucket
- I'll bring my Dell Latitude laptop with the Arduino IDE and other resources on a guest login
- I think the # of pencils we already have should be fine (I'll bring my electric sharpener)

|Re: [makersalliance] Embedded Electronics Classes/Kits for Ingenuity||Sam Harmon||9/10/12 10:47 AM|
Ok, it's now the week of Ingenuity. Who's ready?
-Mouser & Digikey orders are in, so we should have all of the Drawdio parts except the PCBs.
-Diavolinos and FTDI friends have arrived
-Learn to Solder Badges have arrived
-Some electret microphone elements and other things were ordered Friday, they should arrive today or tomorrow.
-I ordered mylar bags and picked up some Avery labels for the Drawdio kits as well
-picked up some thumbtacks for the Drawdios
Still to-do (feel free to take some of these tasks…)
-Wait for PCBs to arrive (Sam)
-Zip ties for Drawdios - we have some at the space (enough? are they the right size?)
-Make & Print Waivers
-Make & Print Information Sheets
-Parts Express Order (Sam) - this will happen after tomorrow's meeting, in case there's anything we think of.
--(Good news on this, in their latest flyer, the soldering irons and solder are on sale vs. my cost estimations!)
-Business Card Order (unless somebody gets me a new design by 6pm today, I'm reordering the old-style ones tonight)
-hand tool run (Harbor Freight)? (let's inventory what we have Tuesday and see what we need)
-Get useful information onto the website
--this can just be a static page somewhere? Maybe just use the Wiki?
--group description, links to relevant web presences, etc.
SIGN UP FOR A SHIFT IF YOU HAVEN'T ALREADY. THIS MEANS YOU!
If you want to give a talk/workshop, please put the topic (preferably somewhat electronics and/or microcontroller related) and your name into the "Event" column.
ATTENDANCE AT TOMORROWS MEETING STRONGLY SUGGESTED. I'll be mailing more details/agenda later.
|Ingenuity Fest||Joe ODonnell||9/16/12 10:52 AM|
Ingenuity Fest is fantastic. If you haven't checked it out yet you have until 6 today. There are thousands of people, art, technology, food and last night a band using a large blimp with a moving face on the front of it. The soldering kits were very popular yesterday during my shift. Thanks Sam for leading this whole weekend and all the volunteers. The club table is among the first on the left when walking into warehouse 32, the warehouse is on the east side of the area behind the Science Center.
Park near the Science Center and walk towards the water directly behind it.
