At the Hackaday SuperConference in November, Sophi Kravitz had the chance to look back on the past year of Hackaday.io, and what a great year it has been. Hackaday.io now has over 178k members who have published 12.6k projects with about 10% of those being collaborative team projects. But the numbers tell just a small…
David Kuder designed a SCSI device emulator with a Teensy 3.5 & NCR 5380:
SCSI target emulator based on the Teensy 3.5 (Kinetis MK64FX MCU) and classic NCR 5380 SCSI PHY. Supports multiple targets (Device IDs), LUNs, and device types. 3.2″ x 1.6″ footprint, optionally uses or provides bus termination power. 64×48 pixel OLED status display.
The design files and source code are available on BitBucket:
KiCad is the premiere open source electronics design automation suite. It’s used by professionals and amateurs alike to design circuits and layout out printed circuit boards. In recent years we’ve seen some incredible features added to KiCad like an improved 3D viewer and push-and-shove routing. This Friday at 10 am PST, join in a Hack…
Like many no-code operators, after being on the air for a while, I developed an interest and appreciation for Morse Code [..] I purchased a cheap paddle, but I found the clicking noise a little bit annoying.
The goal of this project was to create a single PCB with an ATTiny4 AVR, a battery, transistors and a 3.5mm connector jack. The paddle is designed to have exposed conductive material in order to read the capacitive touch.
The under 1kB binary code worked well and without error. This made me wonder how small I could make this code. After optimizing the code, I managed to shrink it to under 512 bytes.
From the Rebooting Electronics blog:
The goal is to have as few spins of the board as possible and the process of mocking the board was a huge help
Robert on hackaday.io designed this upgrade for a cheap TP4056 Li-Ion charger board:
I wanted to have a load sharing for my future battery operated project with the ability to charge the battery. There is a load of cheap TP4056 boards from China. None of them has the load sharing or voltage regulator on board so I made my own addon board.
Smrtokvitek has shared the board on OSH Park:
