Thank you for reading this text. There's more below if you're interested.

Me

Big fan of old personal computers and everything obsolete.

Still young enough to not value my time spent, which means I still etch my own circuit boards or wirewrap them.

Prototyping

Various methods which I use to build my own circuits. Mostly scuffed.

Wirewrap

The long lost art of stripping 30 AWG wire and wrapping it around a pin header.

Here are some pros:

• debugging on the fly, just rewrap your connection
• good IC density, wires can overlap unlike single side PCB tracks
• very artsy

and cons:

• wirewrap sockets are extremely expensive, clocking in at 10€ for a single one
• crosstalk at higher frequencies, max is around 10 MHz

Mostly used in the 60's and 70's, where TTL circuits ran at 1 MHz and crosstalk wasn't much of an issue thanks to ''low'' clock frequencies. The example section contains images of same sided wirewrap boards, which you can easily build yourself at a low price.
