For several years now, I've wanted to duplicate the original
vector-display Atari Asteroids on the Gameduino. There's something about
the this early monochrome vector game that I find very pleasing. This
Summer finishing Dazzler presented the perfect excuse.
Graphics is hard. I'm quite pleased with the Gameduino's usability with the Arduino, and people do sometimes mail me with "hey that was easier than I expected" messages. But this year I've been working on another way: a CircuitPython library for the Gameduino.
If you haven't backed the I²CDriver campaign yet, it's ending quite soon. So you have about 48 hours to back it, and be the first to get the I²CDriver and - if you like - associated goodies.
It's been great running the SPIDriver campaign, thanks so much for all your support and comments. If you haven't yet backed it, I have to remind you that the campaign ends the day after tomorrow. Thanks again!
In this update I'm talking about SPIDriver's firmware. SPIDriver is hardware, of course, but I wrote the firmware first. In fact, most of the effort on the project has been spent on the firmware: iterating on the code itself and writing test harnesses for it.
First of all, a massive thank you to everyone who backed the campaign,
supported us with messages, reported issues, helped fix them, ported
their apps to support XTRX, and shared their test results with us.
When we launched the campaign, we had our XTRX prototypes running
stable at 80 MSPS (both SISO and MIMO), but we were saying that we're
confident we can go up to 120 MSPS.
You're probably wondering what is going on with the project and
whether you're going to get your XTRX any time soon. The short answers
are "a lot" and "yes," respectively.
We are excited to announce the launch of our new campaign. With up to 32x32 transmit/receive channels, XYNC is the ultimate Massive MIMO SDR at an affordable price.
We're giving away a handful of XTRX revision 3 boards to the best proposals on how to use them. We've also released a bunch of software. But first, a big thank you.

Hello everybody. As we get close to delivery, we thought we would share with you the security framework we've built into the Wi-Fi Stepper. Given that the board supports large stepper motors with high voltage and current, hacking could result in damage and injury. To us, security is a big concern and we need to get it right. To that end, we'd like to share with you the design choices and methodology used to secure the Wi-Fi Stepper and prevent unauthorized access.
