I have switched to literal old school breadboard construction because it is very cheap.

The nails and wood are all reused.

I have also ditched SMD transistors and resistors because dead bug construction with them is too difficult.

I attempted using screws, but they were too big.

Almost all the components have been added, except for the 1N4004 power diodes.

This construction took an afternoon with a hammer and punch. First you tap the nails with a punch, and then hammer the nails.

I estimate this project could be assembled by children, with supervision. The children could used pre drilled wood, and be given small screws with washers.

I will solder the components to the nails once they have all been added.

I will post videos of the operation of the flip flop once I have completed the power supply.

I wonder if it's possible to find second hand 1N4148s in large quantities in Australia...

Loads of this project has used waste materials. Also it encourages technological independence. I will potentially rename this computer the 'Walden', after Henry Thoreau, whose philosophy this computer embodies.
