Really universal soldering controller

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 heater, or separate. Here is a short list of features: - power: 9-28V, AC or DC - 2 separate heater control channels - 2 independent sensor inputs - current source on any sensor input 3uA - 12mA, wuth 2 bands (x1, x16) and 2 ...

RoomMote- Control the color and sockets of your Room using a Remote, MSP430 and Energia

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 the underlying inspiration for this project. The Mosquito repellents have this obnoxious smell that I would not like to sleep in and these loner mosquitoes who just piss me off by buzzing in the ear, you have to choose a ...

SunAir Solar Power Controller for Raspberry Pi and Arduino

Ever wanted to build your own Solar Powered Raspberry Pi or Arduino system?   SunAir and SunAirPlus are 3rd Generation Solar Charging and Sun Tracking Boards designed by Dr. John C. Shovic at SwitchDoc Labs. You can use this board to power your projects and add a servo or stepper motor to allow it to track the sun using photoresistors to generate even more power! It incorporates a number of outstanding feat ...

Using an Arduino Uno R3 as a Game Controller

Naturally, the Uno does not natively support keyboard strokes, unlike it's Leonardo brother. Most of Google will tell you you need to do some firmware workarounds and ATMEGA reprogramming just to get it working and the entire ordeal is a mess. If you're like me, you've found that out just after buying one. Here is how to get around all that using a bit of Java coding. The ideal solution would be to purchase ...

Arduino PID Motor Controller

INTRODUCTION : The development of high performance motor drives is very important in industrial as well as other purpose applications.  Generally all high performance motor drives use quadrature encoders and PID control because of its simplicity and precise control.  The quadrature encoder acts as a feedback from the motor, it is connected to the microcontroller for furthur processing. With the use of Ardui ...

Temperature controller for K-type thermocouple and MAX6675

After CNCPaul/LathePaul created such an awesome-looking heating chamber, the postie once again knocked on the door at Nerd Towers to deliver yet another eBay purchase - this time, it was a K-type thermistor and breakout module (basically just a MAX6675 on a board with pin headers) We  had looked online at temperature controllers but they all seemed to be quite pricey for what they were - a cheap thermistor, ...

Daox’s diy arduino thermal differential controller

We have a great thread that contains lots of info on thermal differential controllers here. However, I wanted to start a thread dedicated to my own development of a thermal differential controller that I'll be using for my attic heat reclamation project. Tonight I setup a simple circuit that tested the operation of the differential controller and it worked great. Its very simple and adding features later on ...

DIY Thermal Differential Controller – Part 4: Building Your Own

In our last episode, I explained how I redesigned the controller from what I first thought I was going to do. Now, I am going to explain how to make your own thermal differential controller based on mine. As it is, this setup will only control an AC load, but it would be fairly simple to convert it to run a DC load. Here is the list of parts you’ll need. I’ve added links to where I like to get parts from. A ...

Small Arduino DMX controller

In this post we show you how to make a small and useful Arduino DMX512 controller, which can use by example to handle a smoke machine with DMX, or as test equipment, etc… We can use Arduino Mega, Arduino UNO, and other with small changes. Only a handful of inexpensive components are used. In the configuration shown we have 6 channels with variable values, provided by 6 potentiometers connected to the Arduin ...

Arduino Project 6: Web-controlled music player

Our NetPlay project is built on a standard breadboard. In our previous Arduino masterclass we briefly introduced the Ethernet Shield an Arduino expansion board that adds Ethernet connectivity plus microSD card storage. We used that storage as the basis of a simple one-button digital audio player. It was functional but limited to 8-bit mono WAV files with a 19kHz sample rate. We also gave you the software to ...
