AVR Touchscreen Interface 2008-03-14 04:23:56 This AVR touchscreen interface could be the right I/O system for your project. It sure is cool to touch here and there and than have the results displayed in the same place. Its not gonna be cheap because of the touchscreen, but who knows maybe you have one laying around from another project or some [...] Read more:Interface
RC hobby tachometer 2008-03-14 04:17:11 There are some commercially available tachometer’s but why pay for one, when you could built it and have more fun. If you don’t know what a tachometer is, in shot words its an instrument that measures the revolutions. In our case, in rc hobby it measures the revolutions of a propeller (revolutions per minute). This [...]
LED Rainbow 2008-03-17 06:26:52 This is a little eye-candy circuit which continuously cycles an RGB LED through the colours of the rainbow. The speed at which the colours change is adjustable.
The circuit has two options:
1. Switch between the different colours. This makes the effect very noticeable.
2. Have the colours fade into each other. This is a more relaxed effect [...] Read more:Rainbow
Light Grow for Super Efficient Photosynthesis 2008-03-17 06:20:14 SEPT - Super
Efficient Photosynthesis. A grow light made from red and blue LEDs being pulsed. This light fits inside a Altoids container and requires less than 1.1W of energy to grow a 6″x6″x6″ space. Lights can be chained to grow more plants. Total lumens = 111. Plants need primarily red (680nm) light to grow [...]
SMD LED Ring Light 2008-03-17 06:12:40 With the advent of high-output, relatively-inexpensive white LEDs, it is possible for a hobbyist to make a miniature solid-state ring light with surface-mount technology. The LED ring light featured in this article costs about $10 in parts (PCB, LEDs, resistors, wire, and solder). If you’ve never tried soldering surface-mount parts, this is an excellent project [...]
LED Tester 2008-03-17 06:10:13 We all could use this tool, i can tell you from my experience, when it comes to adding a led into a circuit, although its not that a complicated job it tends to get complicated, when the tools you need to test the led, are already measuring something else, or you need to leave the [...] Read more:Tester
Constant Current Power Supply using Pulse Width Modulation 2008-03-17 05:55:48 Light an LED, Power a motor, this simple - ish circuit will accommodate all you constant current needs using NE555 chips! This is a great way to learn about electronics and although not as efficient as using a pre made buckpuck, this is more fun, cheaper and hopefully you’ll learn something too!

Rapid NiMH / NiCd Battery charger 2008-03-17 05:53:02 The following project could prove very useful for those of you who are into robotics, because as you may know robotics uses lots of batteries and needs to charge them fast, so the bots can be up&running again. The authors states that this battery charger charges a NIMH 5-pack battery used in the BiPed robot [...] Read more:Rapid
DIY iPod Nano Doc 2008-03-20 07:54:18 Docking cradles are more convenient if you connect your ipod frequently, but apple charges way too much for them. The ipod nano is especially easy to make a cradle for because it comes with a plastic insert to make it fit larger docks. With this, a cable, and some Plexiglas you can make a dock.

Hexbot the home made hexapod robot 2008-03-20 07:45:04
The HEXBOT is constructed from 12 (cheap) model airplane servos. Each leg moves laterally on one servo and vertically on the other. Conveniently, this type of servo runs on 5 volts. These servos need only a specific width pulse to position it. Once it arrives at its target location, it draws very [...]
AVR gaming project 2008-03-20 07:36:52 David on Robot w/Lasers created a handheld gaming device using an ATMEGA32 and an 8×8 LED matrix. It’s currently running a breakout-style program he wrote and the self contained platform shows a lot of potential. Complete with directional pad and A/B-style buttons, it could be great for those interested in AVR learning and development. (perhaps [...]
Light Show Stick - commercial POV 2008-03-20 07:29:20 Hard to say the words? Make them appear in the air. Customize your messages like “I Love U”, “Sorry!”, or images in JPG/BMP format, install them in the 32-LED Light Show Stick
via usb cable. Wave the Light Show stick horizontally, then your message/image will be [...]
7805 Uninterruptible Alarm Power Supply 2008-03-20 07:24:48
Although this Power Supply
was designed for the Modular Burglar Alarm - it has other applications. It provides an output of 12-volts - at a current of up to 1-amp. In the event of a mains failure - the back-up battery takes over immediately. And when mains power is restored - the battery recharges automatically.

Power Distribution Unit 2008-03-19 06:07:17 Chris writes: I’m very pleased that I was able to build a controller for this PDU and I actually have a use for it which is more than I can say for most of what I build. The initial inspection of the hardware told me 80% of what I needed to know to control it. [...]
Wind Meter with LCD 2008-03-19 06:02:45 This is a simple interface to the windmill power storage. There is a button that the user toggles to get the current voltage and percent charge on the stored energy in the windmill battery(s). to conserve power the unit is controlled by a toggle switch rather than always be on; we work hard to generate [...] Read more:Meter
Ethernet Temperature Monitor 2008-03-19 05:57:59
Zedomax present this really useful project on which you combine a digital thermometer with a Lantronix XPORT ethernet serial device, the result ? you can monitor temperature over the ethernet, from across the globe. You will find full schematics and source codes, everything you need is there in the project.

Veggie oil temperature monitor 2008-03-19 05:47:25 A easy to install temperature monitor for cars and trucks running on veggie oil. Any veg oil used in a diesel engine needs to be heated to at least 160F (ideally more) to achieve a low viscosity. This device has three temperature sensors which can be zip tied to coolant or veggie oil hoses to [...] Read more:Veggie
Really cool robots 2008-03-19 05:40:22 I thought it will be nice to write an article containing some of the coolest robots
out-there with movies on each one.
The firstone will be the BidDog Robotic Mule:
Built by Boston Dynamics, the BigDog is a four-legged robotic mule that can carry over 340-pounds (original version 88-pounds). As you’ll see in the video, it’s very [...]
The world’s first ultra-thin 8.5mm camera module by Samsung 2008-03-22 09:25:56
Measuring just 8.5-mm thin, you’re looking at what Samsung
claims to be the slimmest CMOS camera module of its kind. The 8 megapixel module is expected to supplant the 5 megapixel job found in todays top-end cameraphones sometime in the second half of the year. Fortunately, this isn’t just a case of megapixel marketing as [...]
USB powered easter eggs 2008-03-21 16:09:00
I still prefer the classic way of doing this kind of things, i mean i want real eggs, real red colored in my house. Some USB powered easter eggs are not gonna change the mood in my house. But if you would like some new ideas, you could approach [...]

DIY Oscilloscope up to 5 kHz 2008-03-21 05:33:13 Vassilis Serasidis writes: A few months ago as I was surfing on the net, I saw an oscilloscope based on PIC18F2550 microcontroller and a KS0108 controller based graphical LCD. That was Steven Cholewiak’s web site. I had never seen before so amazing microcontroller-only oscilloscope. That was realy impressive circuit, so I decided to design something [...]
HappyJTAG2 - JTAG AVR interface 2008-03-21 05:17:57
HappyJTAG2 is the new version of the HappyJTAG interface. Why a new version ? well it seems the old happyJTAG wasn’t powerful enough and there is a barrier in performance when manipulating bits trough USB interface. the USB traffic gets to huge to be effective. This is why HappyJTAG2 was created to bring more power [...]
Dog epileptic seizures monitoring system 2008-03-24 13:55:40
Some of our doggy friend’s sadly sometimes have problems. The Doggie 911 electronic monitoring
system enables dog owners and vets to monitor the patterns of epileptic seizures in dogs. The real-time, ATmega32 based system logs the number of seizures, the duration of the seizures, and the time between seizures so that veterinarians can better diagnose [...]
