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.

Hacker (hobbyist)
In home computing, a hacker is someone who modifies software or hardware of their own private computer system. It includes building, rebuilding, modifying, and creating software (software cracking, demoscene), electronic hardware (hardware hacking, overclocking, modding), either to make it better, faster, to give it added features or to make it do something it was not originally intended to do. Hacking in this sense originated around hobbyist circles discussing the MITS Altair at the homebrew computer club.
Hacker artists[edit]
See also: Fractal art, algorithmic art and interactive art
Hacker artists create art by hacking on technology as an artistic medium. This has extended the definition of the term and what it means to be a hacker. Such artists may work with graphics, computer hardware, sculpture, music and other audio, animation, video, software, simulations, mathematics, reactive sensory systems, text, poetry, literature, or any combination thereof.
Dartmouth College musician Larry Polansky states: "Technology and art are inextricably related. Many musicians, video artists, graphic artists, and even poets who work with technology—whether designing it or using it—consider themselves to be part of the 'hacker community.' Computer artists, like non-art hackers, often find themselves on society’s fringes, developing strange, innovative uses of existing technology. There is an empathetic relationship between those, for example, who design experimental music software and hackers who write communications freeware." [3]
Another description is offered by Jenny Marketou: "Hacker artists operate as culture hackers who manipulate existing techno-semiotic structures towards a different end, to get inside cultural systems on the net and make them do things they were never intended to do." [4]
A successful software and hardware hacker artist is Mark Lottor (mkl), who has created the 3-D light art projects entitled the Cubatron, and the Big Round Cubatron. This art is made using custom computer technology, with specially designed circuit boards and programming for microprocessor chips to manipulate the LED lights.
Don Hopkins is a software hacker artist well known for his artistic cellular automata. This art, created by a cellular automata computer program, generates objects which randomly bump into each other and in turn create more objects and designs, similar to a lava lamp, except that the parts change color and form through interaction. Says Hopkins, "Cellular automata are simple rules that are applied to a grid of cells, or the pixel values of an image. The same rule is applied to every cell, to determine its next state, based on the previous state of that cell and its neighboring cells. There are many interesting cellular automata rules, and they all look very different, with amazing animated dynamic effects. 'Life' is a widely known cellular automata rule, but many other lesser known rules are much more interesting."
Some hacker artists create art by writing computer code, and others, by developing hardware. Some create with existing software tools such as Adobe Photoshop or GIMP.
The creative process of hacker artists can be more abstract than artists using non-technological media. For example, mathematicians have produced visually stunning graphic presentations of fractals, which hackers have further enhanced, often producing detailed and intricate graphics and animations from simple mathematical formulas.

Using an ATtiny85 to control power the Raspberry Pi. Momentary switch is used to turn everything on and then to turn it off again later.
The PCB for M2FC, 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.
For more details on the schematics, see: www.cusf.co.uk/2014/07/martlet-2-electronics-schematics/
The PCBs were kindly sponsored by Cambridge Circuit company, thank you!
circa 1976.
My, how far we've come. Kids these days are messing around with microcontrollers. So do I, but I wish I'd had them back then. We had to make do with electronic bird chirps and by gum that was good enough for us.
But had there been such a thing back then as Robot Legos I'd have killed - killed! - to get my hands on them.
