If you are tired of reaching for your tiny volume control knob to adjust your music when using your computer look no further than these projects by Engineering Nonsense and DIY Perks. The top one uses a DIGISpark board and a rotary encoder to adjust the volume via USB and the one below uses a potentiometer to adjust the analog output of your signal feeding your amplifier.
LiPo batteries are used everywhere. You might think twice before you toss them around like the regular alkaline batteries that are much safer and very common. GreatScott shows us how accurate the built in protection circuits are. You probably won’t be surprised to learn that they are not very accurate and often take much more current than expected to trip.
Have a look at this interesting Plasma Arc Vortex Speaker. Unlike the regular plasma ark speakers that you have seen in the past. Via: Hackaday “After replacing the power supply and adding an RC snubber across the flyback transformer primary, my plasma speaker is already much louder. The addition of a more powerful PSU, it allowed me to also reduce the number of turns on the primary, which increased the
Here is a project to get your SMD projects built with ease. Via: Electronics Lab “This particular instructable is based on the ControLeo2 reflow oven controller by Peter Easton. This is by far the best I’ve come across and the software is fully open source. It can control up to 4 solid state relays (SSRs), a servo motor (to open the door for cooling at the end of reflow
Apple produces a lot of electronics, unlike a pop can something like an iPhone is not the easiest thing to melt down and turn into something new. Apple wants to go green by allowing the recycling of your devices when you are done with them. “Introduced onstage in a peppy video, “Liam” the robot — more specifically a robotic arm — was specifically developed by Apple engineers to pick
Are you looking for a new project and have 3 or 4 months to dedicate to it this 3D LED Spectrum Analyser Project by Pianistos might be just the ticket. If you don’t have access to some of the equipment that he has it could take even longer though! He is able to make a bunch of jigs that allow him to quickly place and solder hundreds of connections where if you
Mike has taken apart a GFI Circuit Breaker and tested it to destruction. These devices are great to make electricity safer when used in dangerous environments such as beside water sources. They measure leakage current and trip when there is too much running from your hair dryer that accidentally fell into your tub full of water. “A GFCI works by measuring the current leaving one side of a
