Things are getting along quite well in the new lab. Large pieces of aluminium have been turned into small pieces of aluminium (and a lot of swarf), spectrometers have been upgraded and calibrated, and I’ve just finished building some constant current regulators for low currents.
The current regulators don’t work how I thought they should, but they seem to work nontheless. I should try and work out what is or isn’t happening, so I have some idea why things are not how I planned them.
the best soldering iron are those using non-filament heaters, the tip should be made of steel alloy too-.~
i use those copper tipped soldering iron but after a month or two, my soldering iron tip would just break ,,
