At Hackaday we’re very happy to see the increasing number of open hardware devices that appear everyday on the internet, and we’re also quite thrilled about open-source electric cars. Pictured above is the GEVCU, an open source electric vehicle control unit (or ECU). It is in charge of processing different inputs (throttle position, brake pressure, vehicle sensors) then send the appropriate control commands to electric motor controllers (aka inverters) via CAN bus messages or digital / PWM signals.
The project started back in December 2012 and was originally based on an Arduino Due. Since then, the GEVCU went through several revisions and ultimately a complete custom board was produced, while still keeping the Cortex M3 ATSAM3X8E from the Due. As you may have guessed, the board also includes a Wifi transceiver so users may adjust the ECU parameters via a web based platform. All resources may be downloaded from the official GitHub.
pedalSHIELD by Electrosmash, is a programmable Arduino open-source guitar pedal made for guitarists, hackers and programmers. It plugs into an Arduino Due and allows you to program effects in C/C++ or download ready effects from the online library.
It is designed to be a platform to learn about digital signal processing, effects, synthesizers and experiment without deep knowledge in electronics or programming.
Last June, Kris Temmerman was featured on this blog with a painting machine made with Arduino Due. Now he’s just sent us this cool project he made for his office window:
My house/office has a store window and I try to make use of it as much as possible. I had some projections etc. in there before, but now I wanted to make something interactive. We have a lot of loitering youth and many people passing by. To appeal to a wide audience, I thought it would be nice to make an old fashion arcade box like thing.
It’s now on the street for one day and people really seem to like it. Age or background doesn’t make a difference.
To make it a little bit more challenging, I thought it would be fun to try to run the hole thing on an Arduino without an external computer. Just to see how much power it actually has. And while I was at it, I decided to try to make everything myself. So I also made my own led screen, with his own “display driver” and display list, a 8-bit sound library, and of course the game itself.
Kris shared on his blog all the documentation to make your own version, check it out!
TinyG2 is a cross-platform ARM Port of the TinyG motion control system that runs on the Arduino Due. It can be used with the gShield to build a high performance 3 axis motion control system.
G2 has a number of advanced features, including
6 axis motion control – XYXABC axes
Can control up to 6 motors (3 are on the gShield)
Jerk controlled acceleration planning – S curves using 3rd order motion planning
During World Maker Faire in NYC we met Alden Hart. He is part of Synthetos where they built TinyG and the grblshield and experiment on other cool stuff for the hacker/maker community:
We chose the Due as the platform for the TinyG ARM port because it’s powerful enough to really run the application well, but it’s still simple and accessible so people can extend the application and experiment with new functionality.
You can learn more about TinyG on their open wiki maintained by Synthetos team, it serves as a user and programmer manual, and documents progress on the project: anyone can post wiki-type stuff.
Ci aspetta un week end intenso: mentre Davide e Pitusso tengono il workshop base di Arduino a Matera, a Venezia (presso H-farm ) si tiene il secondo codemotion di quest’anno, che vedrà il nostro Cristian Maglie raccontare l’Arduino Due e il cammino che abbiamo intrapreso per realizzarla.
Arduino sponsorizza anche l’Hackaton sulle emergenze, offrendo 10 Arduino e breadboard ad ogni gruppo e i premi (Wifi shield e due Arduino Due).
[Stimmer] on the Arduino Forum hardcoded a way to display 160×240 (320×240 after some posts) VGA signal.
After working out how to do a timer interrupt I’ve had a go at making a VGA framebuffer. It is rather low-res at present(160×240) and fuzzy but I hope to be able to improve that. It has 8-bit colour (RRRGGGBB).
I cannot get Eagle to run right now so will have to describe the schematic in text:
Due pin 2 -> VGA pin 13 (HSync)
Due pin 3 -> VGA pin 14 (VSync)
Hamburg Maker Meeting 2012, which took place last week and involved about 200 visitors and more than 20 exhibitors, has been a fantastic opportunity to meet and share experience regarding several topics, such as 3D printing, hacking, retro gaming and so on. At the Attraktor Makerspace, several projects have been presented and demonstrated by their inventors, among which we highlight a very nice Arduino-based floppy drive organ that has been employed to play the Tetris game theme.
Moreover, among the others events planned for the meeting, a special sneak-preview session allowed all the interested people to get some insights on the new Arduino Due board, released a couple of days ago.
A video of the event can be found here, while here you may find more pictures.
