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...

timelapse of power and arm/fpga soldering up
Log from LayerOne 2014 Conference Badge
we did a timelapse of arko hand assembling the first couple of rev3 boards since we can't pick and place them and test as we go along.

added a larger OLED
Log from LayerOne 2014 Conference Badge
Terrible cell phone pic, the 1.3" 128x96 OLED SSD1306 is a direct drop in replacement for the 0.96". Though it is $5.00 vs $2.57 , I do like the bigger display . I'll hopefully take a better pic of it, certainly couldn't take a worse one....

LF Antennas arrived from PCB house
Log from LayerOne 2014 Conference Badge
Just took them out of the box, need to test them and see if they've worked, RF is black magic.The other boards are also out for manufacturing. They should be here this week , hopefully since we have to pre-build a bunch!

Oh yeah I forgot.
Log from LayerOne 2014 Conference Badge
Not only does this badge have an FPGA, but there is also a breakout and chip pads for a BitFury BTC ASIC

anticipation, neoden, parts ordering, BOM.
Log from LayerOne 2014 Conference Badge
we're still waiting on a tracking number for the PCB's, the conference is in just over a week! and i can't finish the code til we get the first one made... oddly enough this hasn't been the closest we've cut it, but its getting there.since there...

fedex and wildfires
Log from LayerOne 2014 Conference Badge
It's wildfire season, but Fedex managed to get our boards from Malaysia to us in good time, unfortunately there was a cock up in the ordering department and they shipped to the billing address, we'd left there about 15 minutes before they showed up with...

Badge PCB's Arrived
Log from LayerOne 2014 Conference Badge
After delays, e-test errors, shipping problems, wild fires and 6 revisions. These completely untested hopefully 4 layer PCBs have arrived. I'm probably just being paranoid but they sure look like 2 layer.Also Arrow decided that I didn't want overnight...
