It’s fairly easy to program a replacement keyless entry remote. Even better, what if you have two vehicles the same make, they use the same remote! Also when the battery goes bad remotes may require to be re paired with the vehicle. Be sure you have all of your remotes handy, the process will clear [...]
I’ve seen videos on YouTube using an Arduino and a Graphical LCD screen (GLCD) to create a simple Oscilloscope. The annoying thing is that I found no help whatsoever on how to build one. I spent a few days figuring out how to use the Nokia 3310 LCD screen and then figuring out how to [...]
As a follow up to my DIY Arduino Oscilloscope video or as a stand alone tutorial, this video should help you understand arrays and recursion in Arduino. You can find the original post here: DIY Arduino Oscilloscope with the Nokia 3310 GLCD screen An array is like a variable in that it stores data but [...]
I had a need for a temperature scanner to troubleshoot overheating on my Duramax LB7 pickup while towing. A commercial solution to collect 6 temperatures may have run me over a thousand dollars so I ordered some thermistors and for about 40 bucks in parts made one myself. Parts include an Arduino Pro Mini and [...]
As it is getting cold again and my chickens made it through the summer just fine, it is time to revisit and revitalize my automatic chicken door. The older model was a large door that slid on a track that would get leaves, snow, and ice messing the whole thing up. Also the mecanisim that [...]
In this video I show how to connect a servo to a Netduino and also how to program the servo library into a new solution. The sweep program will drive the arm of the servo back and forth while the Knob program will move the arm of the servo when you turn a potentiometer. Here [...]
In this video I show how to connect a servo to an Arduino and also how to load the sample servo programs included with the Arduino software. The sweep program will drive the arm of the servo back and forth while the Knob program will move the arm of the servo when you turn a [...]
An attempt to make a good solar reflector out of mirror pieces and a Direct TV satellite dish. If I had it to do again I would have had an actual glass cutter and cut 1” squares…
Peltier Coolers or Thermal Electric Coolers are used to make things hot or cold but have another cool use. Apply a heat source to one side and keep the other side cool and the Peltier generates electricity.
The Zune HD 32 is a nice MP3 and HD video player that can be compared to the IPod Touch. Zune HDs user interface is intuitive and snappy with some really cool features. If you dislike the IPod, ITunes, or Apple this is a really cool device however it doesn’t have the sheer number of [...]
The absolute beginners guide to programming an Arduino Duemilanove for the first time. I will take you through downloading the Arduino programming software, configuring the software, writing your first program, sending it to the Arduino, and testing operation.
The transistor is the fundamental building block of modern electronic devices, it is a semiconductor device used to amplify and switch electronic signals. More simply a transistor is a valve for electricity. In this video I demonstrate the two types of transistors (NPN and PNP) and explain their uses. Here are the two symbols for [...]
A Breadboard is a must for the electronics experimenter type of person for experimenting activities. It is made up of rows of pins that you can simply press in components and wires and they will be held in by pressure.
Adding a solar panel to a RV can provide convenient daily battery maintenance and can extend power available while camping away from civilization. Solar Kits or having one installed can be very costly. As I have not found any help regarding do it yourself installation I decided to document my experience installing my own solar [...]
