Silly Job Title: Wire Whisperer. I am the Wire Whisperer!

In this video we do the 17th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Touching Light.

In the video I mention about my KiCad keymaps, you can learn more here: KiCad.

We use the UNI-T UTi260B Thermal Imager to investigate circuit thermals.

We use the EEVblog BM2257 Digital Multimeter to measure circuit current draw.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

In this video we do the 19th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Touch Buzzer.

This circuit uses a Darlington pair to amplify the very weak signal from the touch sensor.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to look at the square wave from the astable multivibrator.

We use the UNI-T UTi260B Thermal Imager to examine the thermal characteristics of the circuit, particularly the 1K resistors getting warm.

We use the Riden RD6006 Bench Power Supply to provide 9V for our circuit and also to measure the current drawn by the circuit in its inactive (11mA) and active (12mA) states.
