Assembly and Testing of the SMD-EMG Amplifier

I finally got around to assembling and testing the EMG amplifier circuit boards. After fixing a design mistake with the board, I was able to get solid readings out of all four boards. The design mistake was a fairly obscure one, but provided me with a valuable learning experience. Schematic and Layout For the amplifier components, I used a … More Assembly and Testing of the SMD-EMG Amplifier

Attention: I have since improved upon this circuit. Version 2 is covered here. Introduction If you are a Star Wars fan like me, you probably wish that the Force was real so you could manipulate objects without touching them. What if I told you that the Force actually did exist and you had the ability to control … More Control anything using your muscles – How to build an EMG amplifier
