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
The Shrinking Transistor
How big are modern transistors? Surely they must be much bigger than an enzyme? Well, not quite. The picture below shows two transistors, both about 22 nm wide. Superimposed on top of the right-hand transistor is a single molecule of … Continue reading
