first what youll notice my grammer isnt the best 🙂 ok what youll need: 1 transister/mosfet that can handle the current for the water gun motor, this is the one i used – http://www.sparkfun.com/products/10213 – then a diode, i used this one – http://www.sparkfun.com/products/8589 – then a 10k ohm resistor, then a PIR, i didnt use this one but it should […]

A while back I saw an EMF (Electromagnetic Field) Detector at makezine.com that used a led bargraph. I decided to modify it to use a 7-Segment LED Display! Here’s my project. Sorry I don’t have any pictures of it in use. Hopefully I can post some soon. Credit goes to Aaron ALAI for the original

This project originally started out with a few simple parts thrown together to create a very simple time-lapse controller for a DSLR camera. After I was happy with the initial prototype, I wanted to make a final version which the programming of the “lapse time” was self contained into one single entity instead of relying

Following the popularity of our self balancing scooter and the SciChair we decided to try something a little edgier, the Self Balancing Unicycle. This project reuses a lot of stuff from our previous projects, using an arduino as the brains behind the scenes. Step 1: Ready your tools Before we begin lets ensure we have

Goals Hello all. I hope to please share a little robot that I have just finished building. There are many Ping Boat, perhaps with a tutorials and display less so without pretension, will illustrate what I could do. I gave myself the goal of realizing a robot that avoids obstacles, hence the use of Ping,

There are lots of people who are very comfortable with the Scratch programming environment but want to try something with Arduino to Blink Lights, Sense Buttons, Run Servos or whatever. They may find the C programming environment in Arduino IDE – Sketch, a bit too much of a step. This instructable draws on the work

By popular request this is a new wireless version of the Visual Network Threat Level Indicator. This uses a Roving Networks WiFly RN-XV Module to do 802.11 WiFi along with an Arduino to display the threat level on your network. Network monitoring is very important in todays world. The internet is a scary place. People have taken

Recently I saw a documentary about the history of the television. And to my surprise they showed that there existed a mechanical television before the well known CRT televisions. Those mechanical televisions or televisors were pretty smart and simple. A CRT is simply an electron beam that scans a surface covered with a luminescent phosphor line by

A quick demo video for your pleasure. This is an instructable for a target practice system for airsoft and nerf weapons. The system has been designed to test a shooter’s reaction times and accuracy. Sam and I have been meaning to do this project for a while, and when the microcontroller competition opened, coinciding nicely with
