The soldered up M2R, Martlet 2's radio.
The radio board features a uBlox MAX-M8Q GPS with an LNA+SAW on the input, a Radiometrix MTX2 which can either connect directly to the output or go via a 500mW RF power amplifier, and an isolated connection to a RockBLOCK Iridium satellite modem. It's all powered by an STM32F303CBT7 microcontroller.
Fore more details on the schematics, see: www.cusf.co.uk/2014/07/martlet-2-electronics-schematics/
The PCBs were sponsored by Cambridge Circuit company, thank you! The Radiometrix MTX2s were sponsored by Radiometrix, also a big thank you!
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.
Here's my workbench (and the tiny room it's in) for the BricoGeek contest.
This is in the vanity attached to the master bedroom. The workbench surface is 3/4" ply with a cheap pine dropedge, and sits on spacers above the sink. Standard bathroom-style cabinet below stores the larger parts and tools.
The medicine cabinet holds a few finished BEAM bots, power supplies, and chip programmers.
Opposite the bench is a floor-to-ceiling linen closet, which is full of more tools, parts, toys, books, notebooks, etc...
On floor, bottom-right, is a large three drawer tupperware thing with even more parts, tools, and waiting-to-be-scavenged tidbits.
Thanks for looking,

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!

THANKS and our COMPLIMENTS to its developer Mr. Wassner from Graz, Austria, who was so kind to visit us in Munich! :)
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.
Almost there! I just need my UART, SRAM, and trickle charge time keeping chip to come in, and I can do my first full test.
