A short review on my new Christmas gift, a neat digital soldering station, ZD 937, and a quick light installation that I did with LEDS, running directly on mains , 220V, using the ZD937.
Read a post on my new acquisition, a Bauch&Lomb compound binocular microscope, a high quality tool, put to some good use to capture a few micro photographs. It can get up to 1000X with its current optics.
A quick CCD replacement for my Canon S2 IS camera. CCD IR filter removed to enable IR photography options.
A Longitudinal Excitation Nitrogen Laser design, using a fridge pump for vacuum and N2 from air as lasing medium.
Get X-ray intensifying/fluorescent screens from X-ray cassettes used for radiography.
A scintillation probe enclosing the regulated high voltage supply, the signal amplifier, the photomultiplier and the scintillation crystal (NaI). Building a DIY counter for a NaI Scintillation probe. AtMega8 and a bluetooth module for wireless data output. A cheap and easy to build homemade dosimeter with applications in spectroscopy.
This is about lasers, a short article where I speak about a 100mW red laser that I’ve recently built. Lots of interesting photos included.
