Weekend Project - Motor Speed Controller
An easy “weekend” project to make a motor speed controller based upon the readily available 555 timer IC and pulse width modulation control.
Circuit design (based upon the 555 timer astable configuration), component value selection, 3D printing of custom enclosure, veroboard component layout and project construction demonstrated.
See my website for schematics, STL files, etc: http://www.fadstoobsessions.com

Demonstration of "converting" an analog oscilloscope into a digital storage oscilloscope. The "poor man's" version ! "Webcam Oscilloscope" is software that uses a webcam connected to a PC to capture video and images from analog oscilloscopes. The video and images can then be analysed using on-screen cursors for typical Digital Storage Oscilloscope (DSO) functionality.
The software and instruction manual are available for free download at:
