So if you are like this Lazy Old Geek, you have a lot of rechargeable batteries lying around. I wrote another Instructable with some battery tips. http://www.instructables.com/id/Rechargeable-Battery-Tips/ Amongst these batteries, I have a lot that no longer work or don’t work very well. So I decided to try to revive them. First step: If the

A friend of mine wanted to control Cubase, his audio recording software, with a push button so that he could stop and start recordings remotely without having to go over to the computer and type on the keyboard. You may be able to do this in other recording software, we just happen to use Cubase.

In this Arduino-based project, we will build a lamp with multiple light displays: color sequencer, dimming light, color chaser, firelight – all selected by a touch bar on the circuit board. All the functions are done in software, including the touch sensor, which is a unique feature. Step 1: What is needed? We will be

Origami is the traditional Japanese art of paper folding. In this project, with a little help from an Arduino, you can bring your origami into the 21st century and make it an interactive art! The result shown here uses Bare Conductive paint to give an origami flower proximity sensing powers. When you put your hand

Hey guys, I’m back with another instructable. This is about RC speed controllers. What this will do is allow you to test out your speed controller in the Arduino world using Serial, then you write the values down and can use them for your projects. Submitted by Newton Labs for the Instructables Sponsorship Program Step

I needed a couple of AA batteries and found the display at the supermarket where they were all arrayed. Normally when I’m shopping in the supermarket, I tend to look at the price/kg or price/l when comparing similar products. In the case of the batteries, there was no such indicator. Fine, I thought, I’ll work

One of the basic tasks in many home automation systems is controlling power to appliances. They could be lights, or a heater, or an exhaust fan, or just about anything else that runs on mains power. The problem of course is that it’s dangerous to mess with mains-level power directly and you may even be

Charlieplexing is an ingenius method for controlling many LEDs without using many microcontroller pins. You can turn on or off one LED at a time. To light more than one LED at a time, you can scan the LEDs by turning a sequence of them on and off really fast. The number of LEDs you

Hi from Italy Although many watches are created binary, my project was inspired mainly to this: http:// http://www.instructables.com/id/LED-Binary-Clock-1/, very smart and funny. I tried to improve the design and to add something personal. I think it’s a good result at the end. The project is not difficult, requires patience, it requires a little knowledge of

These days I was reading an interesting post on how to make yogurt “by the gallon,” which explained the need to maintain a constant temperature of about 43ºC (110°F) so the bacteria can grow properly. Commercial yogurt makers are available, but they’re usually too small for producing a full gallon at once. Building your own
