Fresh hacks every day
A complete microcontroller development kit for little more than the cost of a bare chip? That’s what STMicroelectronics is promising with their STM8S-Discovery: seven dollars gets you not only a board-mounted 8-bit microcontroller with an decent range of GPIO pins and functions, but the USB programmer/debugger as well.
The STM8S microcontroller is in a similar class as the ATmega328 … Read the rest
[Peter] tipped us off about his new synthesizer kit, Drone Lab. It has the things we look for a synthesizer: knobs, inputs, switches, wacky sounds. You can get your soldering on with the kit version, or buy these pre-built. Peter bills this as an open source kit but we didn’t see board artwork, just a schematic.
What we didn’t … Read the rest
adafruit industries’ latest product is an adjustable breadboard power supply kit. We’ve seen breadboard supplies before, but like most of adafruit’s kits, this is the best design you’re going to encounter. It uses an MIC2941 voltage regulator instead of the more commonplace LM317. It has a very low dropout which means your output voltage can be much closer to … Read the rest
[Alex] of tinkerlog created a set of 64 RGB fireflies that synchronize to blink all at once. We covered the kit earlier, but he has assembled a set of 64. Each firefly is independently controlled by an ATtiny13 that reads a phototransistor and lights up an RGB LED. The fireflies are programmed to blink a certain rate, but blink … Read the rest
Reader [Bradley] sent in his ArduiNIX project, an Arduino shield designed for driving nixie tubes. The shield allows the Arduino to drive and multiplex nixie tubes without any additional hardware. These antique-looking displays are commonly hacked into clocks. It takes 9 volts from a wall wart and steps it up to over 200V in order to drive the … Read the rest
Where’s the Party At is an open source bendable 8-bit sampler kit created by [Todd Bailey]. The initial design started about a year ago when he was instructing circuit benders how to transition to circuit design. He designed the kit to show how simply you could build a sampler. It demonstrates both clear analog and digital design. It’s meant to … Read the rest
Fundamental Logic is selling a Bus Pirate kit and bare PCB based on our universal serial interface tool. They started with our serial port-based v1a hardware, and modified it to use all through-hole parts. 8pin DIP LP2951ACN/-3.3 switchable voltage regulators replace the surface mount TPS79650/33 that we used. The PIC is pre-programmed with our latest … Read the rest
