The soldered up M2FC board, Martlet 2's flight computer.
The flight computer features three K-type thermocouple inputs, three strain gauge half-bridge inputs, three 1A pyrotechnic outputs, a full IMU (±20g and ±200g 3axis accelerometers, 3axis gyro and magno, barometric pressure), a micro SD card for datalogging and a serial interface to the radio and other peripherals. It's powered by an STM32F405VGT7 32-bit ARM 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!
Investigating why a car key fob is un-reliable. Notice how the pin of the battery holder is no longer soldered to the board.
This is the human interface for the contraption. The backbone is an Arduino Mini Pro. It's connected to the camera unit via a 315mhz RF link and takes input from the user via five potentiometers and three pushbuttons

I forgot I had this one. While poking around for something else, there it was. You know you have too much stuff when that starts happening. Can't even remember where I bought it. If it was ebay then I paid too much.

Have an electrifying weekend.

My vote for "technological innovation of the 20th century" - the transistor.
You could manufacture a single microchip with way more transistors than these in it nowadays.
A cute little VOM in a black bakelite case. These were pretty popular in Canadian high schools like the LSG 10-A, hence, they are everywhere.

History of DIY audio
Audio DIY came to prominence in the 50s to 60s, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.
While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest. DIY is especially active in loudspeaker and in tube amplification. Both are relatively simple to design and fabricate without access to sophisticated industrial equipment. Both enable the builder to pick and choose between various available parts, on matters of price as well as quality, allow for extensive experimentation, and offer the chance to use exotic or highly labor-intensive solutions, which would be expensive for a manufacturer to implement, but only require personal labor by the DIYer, which is a source of satisfaction to them.
