If you are interested in seeing what is going on with your garden this Garden Monitor Project is something you should take a look at. It is using a Picaxe microcontroller and has an interesting home brew communication process. All of the schematics and source code are also provided. "One day we had a good hard rain and I could see it the graph of the data; the surface temperature
This Hyperbike looks like it would work well in the long sunny days of summer, the batteries should have a decent charge by the time it is needed for the trip home. "The Hyperbike feasibility study will investigate the influence of emerging storage and electric machinery and control technologies on electric bicycles (PEDELECS and work bikes). New opportunities arise from new efficient and lightweight electric machines, inverters (buck-boost) and
Congratulations to the winner for the last contest. The prize will help you to have a closer look at custom circuit boards, board repairs etc. This contest will run for one week (July 5 – July 11, 2008) . Ending time is based on central standard time. To enter, identify the item pictured above and give an example of what can be done with it. Please do not give
If you want to make a project that is a bit creepy, this Robot Spider is for you. It uses a powerful Parallax microcontroller so it could also be adapted for many other purposes. "Microcontroller: Javelin Stamp (with Ubicom SX48AC, Parallax) Sensors: 1x ultrasonic sensor (Deva-tech SRF04) 2x sensor with micro-switches Actuators: 3x Standard Model servos for the musculoskeletal 1x Micro servo to the pan of ultrasonic sensor "
I have never seen Polymorph before. It’s a plastic that can be melted in hot water, molded in your hands and when it dries it is rock hard! Using not much more than some Polymorph, some cordless screwdrivers and some wooden curtain rings this robot by XRobots was created. " I constructed the pelvis part for the android first. This is made from aluminium strip material to make a
I love using old computer equipment and breathing new life into it. That is exactly what Giovanni Militano did when he took some electrical parts and stuffed them into an old CD-ROM case. The resulting DIY Headphone Amp looks great! "This headphone amplifier will reside primarily on my desk at work, so it needs to fit into an office environment. Fortunately I had a dead Plextor external CD-ROM kicking
This LED Painter system looks like it works very well. If you want your living-room to groove this may be the ticket for you. It is using a chip by TI that I have never heard about before, I can see the TLC5940 being incorporated in many products and DIY projects. "The LED Painter is a 16 channel RGB LED controller (or 48 independent LEDs) using the Texas Instrument
