Watching the International Space Station

Here are a few pictures I took of the international space station for the first time, showing it trace a line through the sky as it follows its orbital path. I very highly recommend everyone try this themselves, it is truly amazing and something you will not soon forget. You do not need to be in an extremely dark place to see it either, on very bright passes it can be brighter than the full moon, quite hard to miss. The ISS orbits relative to the surface of Earth a 22,000 km/h, so it moves quite fast, often only having a duration of two minutes. A good rule of thumb I have found is, if you can see Jupiter and Venus, you will definitely be able to see it, even on its darkest passes.

Ultra High Vacuum Research System

I am in the process of building an Ultra High Vacuum system for future projects and experimentation, which will provide me with a means of achieving the extremely low pressures necessary for more highly technical applications, such as that of having a Farnsworth Fusor reach “star” mode, where the highest fusion activity is, and produces more neutrons as a result. As noted in my last vacuum system post, I acquired a Daia DPF-4Z four inch liquid cooled oil diffusion pump with a vapor trap and pirani gauge from a retired SEM, seen below.

This pump marks the most major step in this project, as it is arguably the most important part. I have also built a cooling loop system for this pump’s water jacket, out of a retired sharp water cooler. The water cooler is essentially a stainless bucket with refrigeration lines wrapped around it, so I simply installed a water pump and a return path to make a recirculating heat exchanger, seen below.

The next step will be a vacuum chamber, which I already have plans for, and the subsystems related to running the pumps and cooling lines correctly, with sensors and data recording. Images provided below of the pump, a Daia DPF-4z

My new Diffusion pump: DAIA DPF-4Z

I recently received my new (to me) 4 inch oil diffusion pump from sunnking on eBay, and wow! this thing is a monster! This is a 4 inch water jacket oil diffusion pump from a scanning electron microscope, complete with accessories, I am unsure of what they all are, but there is a large reservoir, a pirani gauge, and some sort of piston and micro switch. More research is needed, as the pump just arrived. I plan to use this pump in the future for some hardcore projects, including a very large Farnsworth–Hirsch nuclear fusor.

Linksys WRT54GX2 Serial sniffing

 

I decided to read off my old Linksys WRT54GX2 Serial Data line, and this was what I got. I haven’t done anything with it, I was just curious and thought I would upload it if anyone wants it. Also, The serial pinout for anyone interested.

SOHO X-ray Generator Intensity Measurements

SOHO, my X-ray generator, was recently measured  with the Geiger counter in logging mode. By reading the data through a serial port, the intensity measurements that I accomplished are as follows:

CPM: counts per minute
uSv/hr: microsieverts per hour

Background Radiation:
CPM: 23   uSv/hr: 0.14
Two second generator burst at three feet away:
CPM: 2300   uSv/hr: 12.72        (counter switches to fast measurement mode)
Five second generator burst at three feet away:
CPS: 84   CPM: 3996  uSv/hr: 22.77       (counter is switched in fast mode)

Tempest SGTC MMC array

Tempest SGTC MMC array

This is the capacitor array for my spark gap tesla coil Tempest. The capacitor is 13 nF at 16,000 v. I will be updating with more posts soon about this coil, It is an NST based spark gap type tesla coil with an MMC comprised of 100 1600V polyfilm caps. The secondary is a 24 AWG 14 inch tall coil on a 3 inch pipe, an the topload is a short run of aluminium vent ducting.
