Yay, another mini-project with the ATtiny10! A while ago I devised a scheme to drive an electronic dice with only two IO lines. I finally found the time and motivation to build up a small design using this as an entry for the hackaday 1k compo

Over the last decade or so, battery technology has improved massively. While those lithium cells have enabled thin, powerful smartphones and quadcopters, [patrick] thought it would be a good idea to do something a little simpler. He built a USB power bank with an 18650 cell. While it would be easier to simply buy a USB…
tomcircuit created this retro computer board:
Hitachi HD63C09 clocked at a blistering 3 MHz with a capacious 64K of RAM! Retroputing bliss…
The design files and source code are available on GitHub:
tomcircuit/hd6309sbc
tomcircuit has shared the board on OSH Park:
We don’t always JTAG, but when we do, we use a Black Magic Probe. It’s a completely open ARM-chip debugging powerhouse. If you program the small ARM chips and you don’t have a BMP, you need a BMP. Right now, one of the main producers of these little gems is running a Kickstarter where you…

Sarunas designed this RC receiver replacement which uses a smart phone as remote controller via WiFi or Bluetooth:
Smart RacerWhy not control your RC car with smart phone?
Features include:
The design files and source code are available on GitHub:

Here’s the Smart Racer in action:
The first meeting of Hardware Happy Hour (3H) Chicago is Tuesday, December 6th, with Chris Gammell of The Amp Hour and Contextual Electronics. Our Drew Fustini will be there along with Andrew Sowa and many more:

Sarunas built this device to replace a bunch of different remote controls with a smart phone:
Build your own universal remote
Features include:
A solar version was also designed to avoid having to change the battery:
Despite that Bluetooth Low Energy device uses so little of it, the battery will eventually run out. To overcome that, the old device was improved by adding a solar charger.

Jakub Polonský created this solution to make breadboard prototyping safer for components:
adjustable and programmable electronic fuse especially designed for breadboards – a breadboard fuse, or BFuse
The trip current can be set from 50 mA to 1 A but it can measure current up to 6 A [..] It has reverse polarity protection (by P-FET), transient voltage suppressors both on its input and output and two LEDs for indication
Set current and actual current can be compared using ATTiny’s built-in comparator or sampled by the ATTiny’s ADC. Then, the microprocessor controls a P-FET switch that opens or closes the power supply
Ever since Jimi Hendrix brought guitar distortion to the forefront of rock and roll, pedals to control the distortion have been a standard piece of equipment for almost every guitarist. Now, there are individual analog pedals for each effect or even digital pedals that have banks of effects programmed in. Distortion is just one of…
