If you need a cool way of monitoring your computer performance this DIY Computer Performance Monitor which is based on the PIC18F2550 should fit the bill. “The USB Performance monitor is a PIC18F2550 based device which shows the performance of your computer using two analogue meters and a RGB LED. The design is based around a stock Hi-Fi VU-meter which is controlled using PWM from the PIC18F microcontroller.”
Our friend Daniel Eindhoven will be selling Handmade Teslacoil Toroids along with other high voltage fun parts on his new web store. “If you want to spin something you first need a mandrel to spin the metal sheet onto. The mandrel can be made of a variety of materials, but if you want it to last you’re best off making them of steel. I started with two steel disks (190
If you want to know how much current your electronic devices are drawing when they are turned off this DIY Standby Current Monitor will do just that. Back in the day when a power switch physically turned off the power to our electronics this was not a problem but these days the power button is normally just a soft input that simply turns the unit into standby mode. This is
Our friend Carl who has been featured here many times in the past for his laser projects has made an improvement to his Spinning LED creation. Have a look at the new Spinning RGB LED Ball. “Unlike it’s predecessor this one has three axes. It was very challenging to build, with a total of 9 slip-contacts, not including the motors. I made it from scrap I had laying around and
With this Motion Feedback MP3 Player you need to keep moving otherwise your tunes will get turned down. It uses a SparkFun MP3 Trigger , Parallax PIR Motion Sensor , and an ioBridge IO-204 Controller. Could this be the end of the mint tin cases? The French Vanilla Cafe tin looks to be a winner. 🙂 “I wanted the IO-204 to change the volume of the MP3 track as motion
Laser cutters are all the rage right now. Prices have come down quite a bit over the past 10 years but they are still not nice and cheap so it would still be a purchase that would hurt a bit. Interestingly there are lots of people who are making DIY CNC machines but not that many making DIY Laser Cutters and DIY Laser Engravers. Have a look at this DIY
Over at the Arduino X10 Collection site there is a two part series in the making of a DIY Geiger Counter Project which is built with an Arduino Microcontroller. Part 2 can be found here. I can’t think of a time I was looking for a geiger counter but you never know. The project is built around a Russian Military SBM-20 Hard Beta and Gamma GM Detector. If you are
