Articulating Lamp for 90mm magnifying glass
thingiverse
I got a 90mm magnifying glass from some Chinese suppliers, but I really needed it for my electronics projects. I stumbled upon an articulating magnifying lamp on Thingiverse, which inspired me to use most of its components. To power this lamp, I used 24 LEDs - 12 LUW503F43/A-02 and 12 WW05A3SWT4-N from tme.eu. Since my printer was unreliable with the knob_and_screw design, I redesigned the base to use a 5mm screw & nut. The magnifying glass has a focal distance of about 37cm, so the LEDs converge at that point. To power this lamp, I had an unrectified power adapter of 12v, which led me to add a rectifier bridge and electrolytic capacitor in the switch case.
