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.”
Thanks to Joshua for sending in this familiar tune being played in a not so familiar way. A PIC18F4520 is connected to an H-Bridge and is pulse width modulating two brushless DC motors to create the Super Mario Brothers theme!
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
John Park posted a cool video of a DIY Delta Robot over at Make. Juan Uberstadt created this robot around an Arduino, we have seen other DIY Delta Robots before but this is the first one that is Arduino based. “The trajectory is generated by a Pathplanner, which considers the Dynamics of the Structure. Maximum allowable torques in joints and maximum allowable forces in Rods are never exceeded. (The robot
Have a look at this Guitar Pickup Winder which is based on the PIC 16F887 Microcontroller that Robert Pickering built. It was created as part of his EET480 Senior Project at Old Dominion University. Have a listen to the video, the sound quality of his home made pickup is great!
If you want to put on a complex fireworks show you need some way of controlling a bunch of fireworks with precision. This system has the ability of controlling 144 individual fireworks circuits! Have a look at the great build log, the system was built with some great care.. Thanks Dustin. “I just finished building the main unit. It has a 144 cue capability; there are 48 on the main
