Fresh hacks every day
Multitouch builds are all the rage now, so it's not surprising someone would come up with a multi-touchless interface sooner or later. [Hanspeter] did just that; his Multi-touchless ribbon controller, a.k.a. Polymagnetophonic Theremin is multi-touch without the touch. [Hanspeter]'s touchless ribbon controller uses an array of 24 Hall effect sensors that activate whenever a magnet mounted on a … [Read more...]
The team at LeafLabs was looking for something cool to do with their new ARM development board. [AJ] asked if anyone had ever played around with Python, so [Dave] cooked up an implementation of PyMite and put it on a Maple board. While the writeup is only about blinking a LED with a microcontroller, they're doing it with Python, interactively, and at runtime. The build uses the Maple Native … [Read more...]
The team at Leaf Labs just released a new library to demonstrate the VGA capabilities of their Maple dev board. Although it's only a 16 by 18 pixel image, it shows a lot of development over past video implementations on the Maple. The Maple is a great little Ardunio-compatible board with a strangely familiar IDE. We've covered the Maple before. Instead of the somewhat limited AVR, the Maple … [Read more...]
We asked for responses to our last Development Board post, and you all followed through. We got comments, forum posts, and emails filled with your opinions. Like last time, there is no way we could cover every board, so here are a few more that seemed to be popular crowd choices. Feel free to keep sending us your favorite boards, we may end up featuring them at a later date! … [Read more...]
[Okie] designed this audio effect shield for Maple. You'll remember that Maple is a prototyping system built around an ARM processor, so there's plenty of power and speed under the hood. First and foremost, the shield provides input and output filters to keep noise out of the system. From there a set of potentiometers let you change the effect, with the manipulation like echo, distortion, and ring … [Read more...]
Leaf Labs is now shipping the Maple R3 boards. [Phil Burgess] gave the platform a look just before launch last fall and the high-powered prototyping board is now even better. New features come in both hardware and software varieties. The bootloader can now be upgraded without additional programming hardware, there's hardware SPI and I2C interfaces, and a newly-polished IDE for Linux and Windows. … [Read more...]
[Jack] wrote in to let us know about a project that creates a virtual microprocessor core based on the ATmega103 by using a Field-Programmable Gate Array. Great, we thought. Here's another rather esoteric project like the NES on a FPGA, but what's the motivation behind it? We asked [Jack] and he provided several scenarios where this is quite useful. Implementing the AVR core allows code already … [Read more...]
