Transistor Based Flip-Flop or a (not)RS NAND Latch
Been a while since I did a posting, too much time spent writing grants, and I mean a lot of time. In this blog I thought I’d describe a small project I did a month or two ago to build … Continue reading

Z80 Microcomputer
Its been a while since I wrote something for this blog, mainly due to pressures of work. However its summer now and I’ve managed to carve out some time to do other work related projects. One thing I’ve done in … Continue reading
Disappointed with Drobo 5N
I got myself a Drobo 5N to serve as a backup of my data and other work. For those who don’t know the Drobo 5N is a 5 bay network attached storage (NAS) device. What is interesting about the Drobo … Continue reading

What do 17 year old science students know (or not)?
This summer I had the opportunity to host five high school students at a UW science camp. I decided to give them a project where they could build circuits that could do addition and multiplication just using resistors. I’ve been … Continue reading

Parallella Board Arrives
I’ve funded a number of kickstarter projects, two of which have come through. The latest kickstarter project to deliver is the Parallella project. This project is an attempt to bring low power and economical multi-core processing to the masses. The company … Continue reading
Building an Analog Integrator
Something I’ve been wanting to do for a while was is to build a simple analog integrator. Here is my first attempt. I bread-boarded the circuit first to get it working then made it more permanent and stable by soldering … Continue reading

Electronic Gene Circuit
The figure below shows a single unit from the Microryza gene network circuit project. The circuit models a transcription factor that acts as a repressor. The output from the circuit is the level of protein which can be fed into … Continue reading
A mini-supercomputer for the rest of us
I recently contributed to the kickstarter project, Parallela which I would like to selfishly mention here. This is an interesting project that wants to develop highly cost effective small parallel machines. For example their smallest multi-process machine will cost $99 … Continue reading
Crowd Funding: Microryza
There is a new crowd funding site has just started that specializes in funding research. Called Microryza, the organization aims to focus on funding risky research projects or educational outreach efforts. Yours truly submitted one of the first projects (no affiliation to the … Continue reading
Analog Computers
Although I was brought up on digital computers I have quite a soft spot for analog computers. I used to have an old web page that had some notes and pictures plus some rare analog construction notes that I copied … Continue reading
