Daniel Eindhoven sent in his latest creation, this is one killer looking coil gun! The laser effects are fantastic. 🙂 If you love coil guns make sure you have a look at our top 5 coil gun list. "Fully semi-automatic, up to 14 shots. Capable of delivering over 18J kinetic energy, and speeds up to 110km/h! (42 gram projectiles). It’s a single stage gun, using a 8800uF(4×2200) capacitor bank
If you are lucky enough to be in Germany you might want to check out the high tech Shell Eco Marathon Europe 2009 entries. The event will be at the EuroSpeedway Lausitz track from May 7th to 9th. One of the teams competing is Team Aurora from KTH Royal Institute of Technology, see some of their car pictures below. "The current European Shell Eco-marathon record for a combustion engine
This Acoustic Gesture Recognition by Gary Halajian and John Wang from the Cornell University Designing with Microcontrollers course reminds me of the Object Scratching Input Device that Chris Harrison made (I later read the references and see that sure enough they reference the Object Scratching Input Device Project). "Our project utilizes a microphone placed in a stethoscope to recognize various gestures when a fingernail is dragged over a surface.
Piezo buzzers can be found everywhere, next time you throw out an old smoke detector be sure to remove the piezoelectric element from it and stash it in your parts bin. If you want to monitor sound with a piezoelectric element it’s not that easy since the voltage produced by the device is so small. Nerd Kits has not only provided a circuit to help out they also walk
Inspired by Erik’s creations, Daniele Benedettelli put together this very elaborate drawing robot. You basically import a picture that you want the machine to draw. Manipulate the image to make the image simpler and let the robot loose to draw it. I can’t wait until my daughter starts asking for one of these LEGO Mindstorm NXT kits. It will be lots of fun for me her.
Cornell University has just completed their ECE 4760 Designing with Microcontrollers Final Projects. There are lots of great projects, this 3D Laser Scanner by Ryan Dunn and Dale Taylor looks to be a flexible scanning system. Code and schematics are provided so that you can learn from their project. "Our project implements the hardware necessary for a laser triangulation 3D scanner as well as a PC user interface for
This is an interesting look inside a Russian Nuclear Power Plant Control Room. It was completed in 1990 after a 8 years of construction. Even though it wasn’t built yesterday I am surprised that it doesn’t have more computer screens to monitor the status of the plant. If you like dials, buttons and lights you would be completely at home in this control room! "Because this powerplant was completed
