Silly Job Title: Fixeruperer. I am the Fixeruperer!
In this video we do the 18th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Rain Detector.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate the tone signal.
We use the UNI-T UTi260B Thermal Imager to investigate thermals.
We use the EEVblog BM2257 Digital Multimeter to measure current and resistance.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
Thanks very much for watching! And please remember to hit like and subscribe! :)
p.s. today I added Fixeruperer to my spell check.

Virtual Display Driver for use with TightVNC on Windows 11
