I recently dug up my old RC transmitter and receiver and thought “How can i control my arduino with this?” so i powered on my scope to see what was going on at the receiver. Sure... Read more
As far as controlling robots goes, makers today are spoilt for choice. WiFi and Bluetooth enabled microcontrollers are a dime a dozen, and integration with smartphone apps is a cinch. Despit... Read more
The purpose of our final project was to create an unstable system that would allow us to investigate classical control design methods by controlling the system using a microcomputer. This wa... Read more
For our final project, we designed a 4-channel temperature controller using PID control. The system was designed to monitor and regulate the temperature of four individual channels by applyi... Read more
Further to my instructable 12V NE555 PWM Controller for Under $3 I have designed and built a simple and cheap DC Motor Direction Controller that can either be used with the PWM Controller, f... Read more
A couple of months ago I picked up cheap WiFi-controlled LED bulbs (one among dozens of very similar devices), after seeing them at a friend’s place. This turned out to be an excuse to play... Read more
Therm is a very small PID controller with an OLED display, thermocouple interface, and USB port. It can switch an external solid-state relay for driving large loads, or a transistor for driv... Read more
Welcome to the never ending saga of Andy and his reflow controllers. About a year ago I published a project writeup showing how I built a PID-based reflow controller. It featured a 640×360 g... Read more
Key Features Wide input voltage range: 4.5V to 60V Wide output voltage range: 0.6V to 54V Light-load efficiency enhancement Low ripple diode emulation mode with pulse skipping Programmable s... Read more
The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heat... Read more
Buzz..Buzzzz..buzzzzzzzz .. That is how a lone mosquito irritates you in the middle of the night trying to convince you that his lullaby is helpful. Insignificant or not, But truly that is t... Read more
