Gauss Weapons are lots of fun because there is some cool science making them work. At first glance it doesn’t look like anything special would happen with the typical Gauss Gun setup. As each magnet/ball bearing chain is reached the energy and speed increases. The effect is stunning because there is no explosives or electrical energy being used, just some normal magnets and the Gauss Gun setup is all you
When you are laser etching some stuff there isn’t much contrast in the end result. There are rub on products that you simply buff off the excess. Only issue is you have a short working time before it is on everywhere for good. I am all about using products that you already own and didn’t know it could be used in a new and creative way. That is exactly what
Finding a case for your latest project is often a challenge. I am always on the lookout for a non standard case that could be re purposed into an electronic project case. I think my fish tank lights is about the best example I have of what I have done when there wasn’t a proper project case available. For another great example of using what is available for a project
Getting a finished look on custom gear is always hard. If it was made in your basement it usually shows. Rabbisu demonstrates how it is possible to make a great looking custom audio panel using the toner transfer and galvanic etching method on some metal panels. The results look great, the only thing I would change is that the dials would all go to 11. Check out the gallery for
Our friend Carlos from Carlitos’ Contraptions has joined the Aldebaran Developer Program, they make the Nao humanoid platform. Thanks to Carlos we will get a first hand view into how this robot works and what it can do. At $16,000 it isn’t a toy but as a humanoid development platform that is a decent price. It reminds me a bit of the RoboSapien but is much bigger and has a
Jérôme Demers from the Université de Sherbrooke built this fun Fart Meter, I can just imagine how much fun this would be in an office environment. 🙂 The meter uses an Arduino to monitor a Methane sensor, the dial then indicates how much gas it detected. Not sure I would want to be a judge in this competition… You probably remember Jerome from his Robot Build that he shared with
If you are a procrastinator and have some electronics in your junk box why not make one of these LED hearts for that special someone. ThermalRunaway did a great job on the circuit board but I think I would have made mine from a heart shaped box of chocolates. The circuit is very simple and I like the way the components are symmetrical and look quite nice when laid out
