Constructing the PCBs

Twitalu v0.1 PCBs

Twitalu v0.1 PCBs

After a very exciting unboxing of the first ever PCBs that Jeremy and I have ever ordered, I started the task of constructing and populating the boards.

The first task was to break the tabs that we had created to avoid PCBTrain’s pricing. This proved to be really easy with a guillotine. The edges of each board were then sanded down on a belt sander to smooth out the tabs. Continue reading

Ta daa!

So here it is guys! Version 0.1 of the Twitalu’s main board. This version implements all the features within a MOS 6502 processor’s ALU. When combined with the registers that Jeremy has built and the software that’s being programmed on the Raspberry Pi, the Twitalu will take its first baby steps by adding two numbers together! Check out the rear side after the break.

All aboard the PCB Train!

Now I know it’s been a little while since our last blog entry but don’t worry, we’ve been busy working on producing schematics and PCB designs for the project!

Not long after the last post we decided that it probably wouldn’t be the best use of our time to produce the entire ALU and registers on breadboard. It’d be big, bug ridden and consume more sections of board and tiny bits of wire than have probably ever been produced.
