I wanted to publish my thoughts on some things before joining the workforce fulltime. Like many others, I’ll be under a contract where everything I think and create must be reported to and given ownership by the corporate overlords who … Continue reading →

So the semester is over and I was not able to accomplish all I set out to. If I could do it over, I would concentrate a lot more heavily on one specific issue, such as fabricating conductive traces. While … Continue reading →

Some of my recent work has been to compile information on printing electronics on the RepRap wiki. I’m hoping to provide a collection of historical and ongoing attempts at printing electronics, be it wiring and traces, electrical components, or semiconductor … Continue reading →

Under the direction of my advisor, I made cadmium sulfide in the lab from cadmium chloride and sodium sulfide. There are several more steps necessary, however, to actually put it to use. In its current condition it is precipitate in … Continue reading →

So the order from MakerGear finally arrived and I’ve begun to put together the Prusa Mendel. It’s quite a lot of fun, and reminds me of building with Legos.

So the graphite-resin-ethanol paint we requested a sample of eventually did come a while back. I’ve been playing with it, and it seems great for what it does. The alcohol doesn’t evaporate as nicely when trying to apply more than … Continue reading →

While we never received a response received a delayed response to our request to sample the one carbon company’s graphite in ethanol solution, I was able to find powdered graphite at the local art store and we mixed it with … Continue reading →

In order to fabricate semiconductor devices like diodes or transistors it is of course imperative to have a substrate on which to do the fabrication. Additionally, to do anything with the devices, electrical connections are necessary. The conductor forming the … Continue reading →
