More Quick2Wire progress

Quick2Wire logo
If you've some Quick2wire hardware and you want up-to-date instructions for using it, you won't have long to wait.

Qucik2Wire made and marketed some add-on boards for the Raspberry Pi. It ceased trading in 2012 but there are still a lot of boards out in the wild, and you can still buy kits from S K Pang.

Sadly the website that told you how to use them is very out-of-date, as are the code repositories on GitHub.

I'm doing my best to fix the problem.

Quick2Wire boards


Quick2Wire interface board
The Quick2Wire product range included three hardware kits. All are still usable, and the software to use them now needs to be much simpler to use and install.

I'll post information here as I update the relevant parts of the website and GitHub repositories.

GPIO Pins and the downverter cable


There's also one hardware problem but it's easy to fix.

downverter cable
The Quick2Wire boards were designed back in the days when every Raspberry Pi had 26 GPIO pins. The interface board was connected to the Pi by a 26-way connector cable.

Recent models (including the Pi 3, Pi zero and zero w) have 40 GPIO pins. Fortunately it's easy to connect them to the Interface board, and SK Pang stock a suitable downverter cable.

**STOP PRESS**

The Quick2Wire domain has transferred faster than expected. I'll put up a holding page later today. Resotring the current contents will take a while, but you should see some content soon.

Marr's theory of cerebellar cortex

I finally got around to publishing my MSc project report from 1974. It's based on a simulation of the late David Marr's theory of cerebellar cortex.


1974 seems a long while ago, but Marr's work is still relevant and I am actively pursuing this line of research using a more appropriate language and a rather more powerful computer.

At some point I will post more details of my current work but for now you can get a copy of the report from Leanpub. It's free.
