Micro controllers are great, but have you ever wanted to control something bigger then, lets say an LED? If you have, look no further (unless you want more then 0.6Amps for 4 channels, or 2.4Amps for 1 channel), unless you don’t mind spending more money. This instructable will be all about building your own, preferably […]

So this Lazy Old Geek (LOG) gets bored sometimes and wants something to do. Actually, sometimes I get tired of trying to solve hardware problems, which are sometimes software problems. So I decided to do a tutorial on Arduino sketches. What is a Sketch? I’m not sure where the term Arduino sketch came from but […]
This project came to my mind when doing my MEM (Mechanical Engineering Measurement) project, a subject in my B.tech. The idea is to measure the angular velocity of my bicycle’s wheel. Thus knowing the diameter and the all time mathematical legend the pi(3.14) the speed can be calculated. Also knowing the number of time the wheel has […]
The Need: Occupational Therapy Device Occupational therapy is used in treating Traumatic Brain Injury during many phases of recovery and rehabilitation. As the patient’s condition improves, occupational therapy helps them regain skills ranging from basic self-care, to complex cognitive skills such as memory and problem solving. Occupational therapy can be helpful for individuals of all ages. Source: http://www.head-trauma-resource.com/occupational-therapy.htm According to numerous […]
Everlasting flower for your everlasting love. A perfect not-only Valentine’s day gift to your loved one. This mechanical tulip will bloom into any color possible with just gentle touch of your hand. Its six petals will slowly open and light up. When petals are closed they create incredible ambient light with leaf patterns. Step 1: […]
This project is a small, battery-powered LED ring that fits perfectly inside of your Rav Vast drum. It uses color-changing RGB LEDs and a microphone that allows you to change the color or pattern with changes in volume. You don’t need any special skills for the construction (though you may pick some up along the way) Step […]
A Smapler is a circuit dedicated to the production of generative sound created by David Cuartielles and Ino Schlaucher from BlushingBoy.org. The Smapler v0002 -aka Singapore edition- is nothing but an Arduino shield to be used for playing funky stereo sounds. As an extra add-on the Smapler v0002 circuit includes a PS2 connector for you […]
A while ago I made a large 20 sided Die. Numerous people wanted me to build them one and since the most difficult part of the project was getting the cutting angles just right, I decided to make another which would allow for more accurate assembly. This time 3D printed instead of plywood and glue. I […]
Although you can buy analog tide clocks that have a single hand indicating whether the tide is high or low or somewhere in between, what I wanted was something that would tell me at what time low tide will be. I wanted something I could glance at quickly without having to turn it on, or push any […]
