 Rolandvanroy is building a six degree of freedom motion platform for a flight simulator. The to move the user large powerful Linear Actuators are needed. Purchasing these actuators would increase the price of the simulator significantly, making a DIY version is a big undertaking bit it looks like a great design that should work well for a long time.
If you don’t look at the scale of the things around it you might think this drive was ripped out of some vintage gear. It is actually a fully functional USB SD card reader that looks just like an Apple II Floppy Drive. “A typical USB SD card reader is boring.

This amazing vehicle can be driven from the the regular lower driving position but to spice things up you simply take the steering wheel upstairs and continue cruising. I would love to see it pulled over
 Kerry Wong built this Thermometer and Hygrometer with Analog Displays instead of the typical digital display.  Via: Electronics Labs and Dangerous Prototypes  “The circuit itself is as simple as it gets. SHT21 is mounted on a breakout board and connected to the ATMega328p board via ribbon cable. The sensor is placed at some distance away from the MCU board so that the measurement is not affected by the heat
This is a cool Nixie Bargraph Clock that has an hour and minute tube, the heights of the plasma in each tube indicates the time. There are some wires wrapped around the tubes so you can easily see what time it is without estimating. The electronics are tucked out of sight in a box out of sight so when you are admiring the clock you don’t see the modern
