DIY 32ch FPV 5.8ghz LCD

If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on the market now.First, crack open that LCD, and look what’s inside. I desoldered the wires, and too ...

DIY Bluetooth RC Car

Last year I started a project to convert my (then) four-year old’s busted Radio Controlled (RC) car into Bluetooth controlled one which could be driven using a smart phone or tablet. The original car, modeled after a “Fast and Furious” Nissan Silvia, was a pretty basic RC with 2-channel on-off (non-proportional) style controls, and while Micah enjoyed playing with it I thought it might be nice to pimp it ou ...

DIY plug-in modules to make microcontroller breadboarding easier

Breadboards are a great tool for prototyping and testing electronics circuits. Here I am sharing with you some plug-in modules that I once made to make my breadboarding life easier. I have used these modules many times in the PIC experiments described in this blog. These modules  serve very common functions that are required in most microcontroller circuits. Their use not only reduces the number of wire con ...

DIY Muscle Sensor / EMG Circuit for a Microcontroller

Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems. Yet, EMG systems remain ...
