A while back, I added a fan controller to my Topward 6603A power supply. Later on, when I bought a used programmable power supply (PPS-2322) I had to do the same thing. Both of those builds were done on protoboards but I had a feeling that many of my other projects could use a similarly […]

The LTC7851 is a quad output multiphase synchronous step-down DC/DC controller with accurate current sharing between phases and differential output voltage sensing. This controller works in conjunction with external power train devices such as DrMOS and power blocks as well as discrete N-channel MOSFETs and associated gate drivers, enabling flexible design configurations. Up to 8
This project is an update to the previous dehumidifier based you can here: http://davidegironi.blogspot.it/2013/04/avr-atmega-dehumidifier-controller.html This update adds some usefull functions. The main issue that i’ve fixed is the microcontroller crash, that happens sometimes. I’ve noticed that sometimes the controller stop running, crash or doesn’t works as expected. After some experimets, i’ve noticed that probem was due

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 driving small loads. When attached to a computer, it enumerates as a USB serial port for easy control and logging of data. The design

The story so far 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 graphical LCD from the Sony U5 Vivaz mobile phone and was all-surface mount. It worked well and continues

This is reflow soldering controller for use with a toaster oven as reflow soldering oven. I bought the toaster oven in a local super market for about 40 €. There was also a cheaper oven on sale, but I wasn’t sure if it did 250°C, so I bought the more expensive and prettier one. Since

Introduction For our Final Project in ECE 4760, we built a controller that interfaces with a computer running a PowerPoint display through USB. The device can control slide transitions based on hand motions or button presses as well as play MP3 files when it detects people near the display. We chose to do this project
