Spin Brushless DC Motors Slowly
Here is some good reference material on spinning Brushless DC motors that should be applicable to the Papilio. We would just need to add some sensors to spin the motors faster… I used specialized triple half bridge IC L6234 (~ 8$). You can make the same spending less money (but more time) with MOSFET…

USB PIDs For All – New USB PID Source.
Making an Open Source Hardware device and need a USB VID/PID but can’t afford $5K? Well now there is a new option for getting your own PID for free! Now, someone has finally done the sensible thing and put an unused USB VID to work. pid.codes obtained the rights to a single VID – 0x1209…

Blog that documents work to create Commodore 65 on FPGA.
Very interesting blog that documents Dr. Paul Gardner-Stephen’s work on recreating the Commodore 64 on an FPGA. Not sure if any of this is Open Source, but fun to read. This is a hastily prepared post with a few screen shots of the C65GS display just to give you an idea of what I am working…

Using a FPGA as a CAD engine
Papilio DUO user Monsonite just posted about a cool project he is making with the ZPUino and the new VGA adapter. It’s a self contained CAD engine and he already has a LQFP-64 footprint rendering on the screen. Stop by the forum and check it out! Hi Jack and Forum, I have been experimenting with…

ChipWhisperer-Lite: A New Era of Hardware Security Research
Our favorite FPGA security hacker, Colin O’Flynn, has a new Kickstarter project that just went online. It’s the ChipWhisperer-Lite which packs a serious punch with a Spartan 6 FPGA, 10-bit ADC, and an XMega Micro. Included with the board is software and tutorials to get you up to speed with embedded hardware security research projects…

HDMI Audio and Video for Neo Geo MVS
Here is a cool project that adds HDMI output to a Neo Geo arcade board using an FPGA. When he tested the HDMI with his monitor, it was out of spec but still worked. His TV, on the other hand, refused to play it at all. This was due to the Neo Geo outputting 59.1…
