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…

askoog89 saw a major flaw with many LED watches – you have to press a button to see the time:
I tried fix that problem by using a tilt switch to active the LED showing the time when tilt your arm to look at the watch
The watch uses the low power MSP430G2211 MCU from Texas instruments to control the LED and mesure the time with the help of a 32kHz watch cristal. The MCU sleeps most of the time only waking up ones a second to count up the time and check if the tilt switch is active. To show the time the watch uses 12 charlieplexed orange LEDs.
Nick Sayer created this simple desk clock that gets time from GPS:
GPS is best known as a ubiquitous, accurate positioning system (obvious from the name), but the way it actually works requires distributing hyper-accurate time information. This makes it possible (and, actually, pretty easy) to make a clock that you never have to set as long as it gets good GPS reception.
Yes, this is way overkill… but GPS is getting so cheap that you might as well.
The source code is available on GitHub:
Nick has hacked together a tenth digit for the clock:
Here is a video of the GPS clock in slow motion:
