How do you detect the actual current from your 22,500uF, 450VDC capacitor bank when you pulse discharge it? Well Norman from Procrastinatus shows us his method. Inductive Current Sensing is done using a Rogowski coil which is wrapped around the high current output of the capacitor bank. A DSO is used to capture the data so the short event can be analyzed. Norman entered this into the Tektronix scope competition
This is a cool looking Bubble Display Project. Who doesn’t want to play an instrument that is connected to bubble making system! I think there would be a lot more piano players out there if this was hooked up to pianos in schools. 🙂 “The board was built to support up to 64 outputs. Each output had an LED. It was a simple design of several I/O expanders on an
If you enjoy photography you know that it can be very hard to capture certain events. Our friend Viktor has built this DIY Lightning Detection for Photography which has a PIC microcontroller controlling the events. The photodiode monitors the ambient light levels and triggers the camera when it sees a lightning strike. This project is safe for your camera since it is optically isolated for your cameras protection. Viktor will
Now that spring has arrived you might be looking for something new to build that can be used outside. Why not make something that can be used to protect your property in a non-lethal way? We have see lots of sentry guns over the years but quite a few of them has closed source code. This Sentry Gun Project has code that has been released which is sure to help
I haven’t been keeping up with the Ben Heck show for the past few months, back in September we featured the the Ben Heck Show when Ben built the custom XBOX controller. I had a look this weekend and Ben has been very busy making lots of new episodes. Love the huge ShopBot CNC machine. Ben goes through lots of the build steps that go into making his projects but
Want to control an army of robots with the sound of your voice? Well have a look at this Speech-Controlled Arduino Robot for a good head start. Carlos Asmat has done a great job with the video that shows how everything goes together. “For this project, I used the DFRobotShop Rover (a mobile Arduino kit), the VRbot speech recognition module by Veear, two XBee modules, an Arduino Uno, two XBee
Remember all the people warning you never to look directly at the sun because you will go blind. Well believe me when I say do not look into the barrel of this gun because it will make you blind. This DIY Pulse Laser Gun was built by Patrick Priebe who you might remember from the Iron Man Repulsor Light Laser Glove Project. This is what you get when you convert
