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 transistors or other IC.

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 – 0×1209 – and now they’re parceling off all the PIDs that remain to open source hardware projects.

If you are like us you have been following Jerri Ellsworth’s castAR project with a sense of awe and anticipation. It’s an amazing project made with an FPGA and we can’t wait to see one of these things in person. Until that happens we found a great teardown video that shows all the pretty insides of the device.
A little more than a year ago, castAR, the augmented reality glasses with projectors and retro-reflective surfaces made it to Kickstarter. Since then we’ve seen it at Maker Faire, seen it used for visualizing 3D prints, and sat down with the latest version of the hardware. Now, one of the two people we trust to do a proper teardown finally got his developer version of the castAR.

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 on.

Everyone’s favorite WiFi chip now has Arduino IDE support. This means that you can connect an ESP8266 via a serial port and choose it as a board type in the Arduino IDE now. Make a sketch, click upload and you are in business with a less then $5 IoT device. Pretty nifty!
What’s supported by the build? The short answer is quite a lot — basic functions like pinMode, digitalRead and digitalWrite work as you’d expect. As do interrupts, and the millis and micros functions, and sensible things done to delay to take account of the background activity of WiFi and TCP tasks, and there is a Ticker library for calling functions with a certain cadence.

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 the Papilio Duo with ZPUino and VGA, as a means of producing CAD gerber files. It’s very early days – but shown is a screen shot of a LQFP-64 package, created on the ZPUino and displayed in VGA. I’ve added a few vias and a 4 thou track for scale. If Chuck Moore could change the way VLSI CAD tools were used in the early 1990s – then I’m sure the Papilio Duo and ZPUino can be applied in this area. Imagine a complete CAD workstation embedded in a mouse – it’s been done before. Here’s a posting from 3/8/2000 by the late Jeff Fox – who worked with Chuck Moore on the early Forth chips Nothing new under the sun – we just forget 99% of what’s gone before us.

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 such as side-channel power analysis and glitching.
ChipWhisperer® is the first open-source toolchain (GPL licenced) for embedded hardware security research including side-channel power analysis and glitching. The innovative synchronous capture technology is unmatched by other tools, even from commercial vendors. Similar commercial equipment is too expensive ($30k – $400k), and being closed-source limits usefulness for academics. Instead this project bridges the gap between academic research and in-the-trenches engineering. Several peer-reviewed publications describe the design, matched with hours of hands-on tutorials for getting started.

Here at Gadget Factory we are happy to announce that our next generation of products are now available at our online store. The long awaited Papilio DUO along with the new Papilio Shields are finally here after a successful Kickstarter campaign that helped us raise more than $62.000 in funds to make this dream come true, here is a short description of each product:
- The Papilio DUO has an FPGA on the top and the same chip that is used in the Arduino Leonardo (ATmega32U4) on the bottom. It’s like having an Arduino with a full circuit laboratory connected to it! For example, you can draw circuits to move pins, connect extra serial ports, or connect a bitcoin miner to the Arduino-Compatible chip. Just plug it into your computer using a USB cable, download our software and start drawing your own circuits.
- The LogicStart Shield provides everything needed to get started with VHDL and FPGA development on the Papilio DUO with one convenient and easy to connect circuit board.
- The Computing Shield provides all of the hardware needed to recreate classic computing systems on the Papilio DUO. Here are some existing retro computing projects that can be easily converted.
To have an in depth look at the DUO and the new Shields please visit the hardware guides and the product pages here, feel free to drop a comment and send us your feedback.
