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…
Combo board for the Raspberry Pi with IR receiver and transmitter along with Real-Time Clock and coin cell battery:
I needed an IR receiver for my Raspberry Pi which I use as an internet TV receiver [..] Solution: make my own.

Jakub Polonský of Kaktus Circuits designed this linear virtual ground with OPA548:
Virtual ground, also called “rail-splitter”, is a device that creates a midpoint, whose voltage is (plus + minus)/2 and is capable of both sinking and sourcing current.
Machinekit is a platform for machine control applications. It is based on LinuxCNC and can drive mills, lathes, 3D printers, laser cutters and more.
Machinekit can run on an Altera SoC which combines a hard silicon ARM core with a FPGA. Charles Steinkuehler has been working with the DE0-Nano development board from Terasic. MachineKit runs on the ARM core with the FPGA configured as a MesaNet card:
Charles designed a DB25 connected interface board, with pin-outs matching the P2 and P3 headers on a 5i25

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…
