Soldering Complete
Log from "Chad" - The NFC Voting System
→InsertImageSo here's the deal. One of my prejudices against Arduino is that it's an expensive board to leave with a project. But this is kind of a one-time thing so I was happy to find the Seeed Studio protoype shield for like $7.95 at the local Radio...

Labels and Out the Door
Log from "Chad" - The NFC Voting System
→InsertImageHere's the test. The LEDs are waaaaay too bright. I sanded the clear domes on them down which helped a bit. This LCD display doesn't ahve the best visibility, but it looks better in person than shown above.→InsertImageThis is the final picture...

Meeting in the Middle
Log from MicroMicro Processor
Simultaneously designing top-down and bottom-up until your designs meet in the middle to produce a functional result. →InsertImageThat sounds like a horrible idea.→InsertImageFor this project, this was the only design strategy that made sense,...

The Beginning
Log from Electric Car Conversion
Prior to high school graduation, Ian Hillier and I were leaders of the robotics club at school -- we even won the 2007 Skills Canada Robotics competition for a soccer playing bot! When we weren't building robots, we built some electric scooters for...

Preparing the Car
Log from Electric Car Conversion
Once we had the car in our possession, it was time to strip it of unnecessary components. First on the chopping block? The engine.→InsertImageNormally removing an engine is a bit tricky, but luckily my friend has a big garage with an underground car...

Forklift Donation
Log from Electric Car Conversion
When we started this project, we didn't actually know how we were going to finance it, or where we were even going to get some components -- but we set the wheel in motion and struck luck!→InsertImageWe had sent out a few sponsor emails to local companies...

Autobots Assemble!
Log from Electric Car Conversion
Now that we have a car and a motor, we need to fill in the gaps. First off is coupling the motor to the original transmission of the car.→InsertImageIn machine shop class I replicated the spline pattern found in the pump motor -- first on the lathe.→InsertImageThen...

Finishing Touches and the Virgin Ride
Log from Electric Car Conversion
Wait a second -- how are we going to control this thing? While a simple ON/OFF switch sufficed for the electric scooters, we don't think it'll work so well with a car...→InsertImageWe picked up an Alltrax 450A 72V golf cart off eBay for a few hundred...

Conclusion
Log from Electric Car Conversion
We did it. We took a 1993 Honda Del Sol, and a equally old electric forklift and merged them together into something we like to call the Delsolectric Car.→InsertImageIt might not be pretty. But it worked. We even managed to get it up to 100km/h on the...

GRL!
Log from L.A.S.E.R. Tag Control
In 2002 the Graffiti Research Lab put together the rather excellent L.A.S.E.R. Tag system which allows you to draw virtual graffiti with nothing more than a camera, a projector and a laser pointer. They've done really awesome things with this showing...

An RGB button...
Log from L.A.S.E.R. Tag Control
I really like these big dome buttons from SparkFun, but they don't come in an RGB flavour. This is really annoying as they would be ideal for the color control on our system.→InsertImageNot to worry though, a couple of minutes with some snips and a soldering...

A little Arduino goes a long way...
Log from L.A.S.E.R. Tag Control
Yes yes, I know, Arduinos are lame. But... they are incredibly handy for getting certain things done really quickly.→InsertImageFor the control system we need to emulate a USB keyboard, it just so happens the Arduino Micro is especially good at this....

Enclosures
Log from L.A.S.E.R. Tag Control
Now we couldn't very well let 500 hackers mess around with a bunch of open wires, so we needed to make a little enclosure for our control system. The simplest way to do this was to grab an off the shelf project enclosure from Radioshack.→InsertImageWe...

LayerOne 2014 Conference Badge
Log from LayerOne 2014 Conference Badge
rev3 board, rerouted and moved components around to try to be closer to final design and clean up noise, split ground planes.Changed SPI's to use the hardware SPIs of the Cortex, they were all Software SPI before, adding all the names to the pins on...

power....
Log from LayerOne 2014 Conference Badge
Arko started putting the rev3 board together last night, we usually build the power section first and measure how it looks, make sure none of the power is shorted in the PCB ( it happens). This board has one always on regulator, its a 3.3V LDO that...
