A kit system labeled Stark on the outside but has Hickok marked on the individual plastic part holders. This kit is full of resistors, capacitors, transistors, tubes, chokes, transformers, potentiometers, diodes, sockets, etc. The plastic boards were snapped together giving the student a base to build hundreds of different projects. I'd love to find an original experiments manual for this unit. I currently have 7 of these and have been attempting to put together complete units. I may end up with 4 total when all is said and done. A couple of these kits are available if anyone is interested.

The electronics bay with 14.6A 24VDC Meanwell PSU available from WanHao USA, Mouser, and other suppliers.
FlashForge Mightyboard rev E clone board with C20 and Extra FET added. FlashForge peripheral terminals replaced with Phoenix screw down terminals. The stepper driver cards are modified Pololu A4988 Black boards. Modified to work with the Mightyboard replacing the standard Botstep cards. Also, the Pololu boards have been adjusted to support the higher current needs of the X, Y and Z stepper motors.
The wiring for the stepper motors is not yet connected.
I recently bought remote controller for PS2 from DealExtreme. But it didn't work. I thought it was bad battery, so I bought new one (in similar price as this remote, lol). And it doesn't helped. So I opened it, and quickly find the problem. It was touching wires of one capacitor. I quickly fixed it with knife, and it works at last!
Here's a little bench power supply I made using the Adafruit Power Supply kit. I just replaced the kit's PCB mount potentiometer with a panel mount pot and added a 7805 5v regulator to power the display. The acrylic panel was made from a scrap piece I had and the heat sink came from a dead PC power supply.
At the 2023 Consumer Electronics Show in Las Vegas recently I was also able to experience a test drive in the Vision EQXX ultra EV. Engineered in just 18 months and representing the most efficient Mercedes-Benz ever built, this experimental unit acts as a barometer for production EQ models, which may eventually inherit deviations from its technology, energy storage capabilities, and driving range. The development intention of the vehicle was to produce a battery with 100 kW capacity, lightweight construction, increased aero, and extreme efficiency. The result is an EV that achieves an extensive range of more than 745 miles on a single charge.
Oberheim Matrix 6R teardown and repair. Up and running, although the display is missing several characters for some as-yet unknown reason.
THANKS and our COMPLIMENTS to its developer Mr. Wassner from Graz, Austria, who was so kind to visit us in Munich! :)
This board contains part of the actual speech synthesizer circuit, which consists of digitally controllable analog oscillators and filters.
