bornach, 8 months ago to Electronics Found 3 SG90 (9g) servos in the e-waste at work. Testing them with my 555 based servo tester. Two still work. One is seized up and just gets very warm #electronics #servo #555timer #ewaste Three "Tower Pro" brand 9g servos (SG90) One of them has a servo arm attached and is being tested using a 555 timer astable oscillator circuit on a perfboard. The duty cycle is varied using a potentiometers. The servo arm rotates in sync with the potentiometer being adjusted.

diyelectromusic, 9 months ago to SynthDIY Inspired by @oskitone I've built some single 555-based square wave oscillators on custom PCBs. Once again my boards were supported by #SeeedStudioFusion. https://diyelectromusic.wordpress.com/2023/09/03/simple-square-wave-oscillator-pcb-design/ #PCBs #555Timer #Oskitone #SynthDIY
