Chris from Pyroelectro shows us how to interface to an FPGA to allow precise control over a DC motor. “The goal of this project is to build a simple one input, one output system that will control a motor. The control input will come from a trimpot and the FPGA or CPLD’s job will be to use the input to create the proper duty cycle PWM output to the
I played a ton of Apple games in junior high, I think Choplifter was my favorite, looks like Taipan was created around the same time but unfortunately I don’t think my school had it. Simon Jansen sent in this hack where he made a version of the Taipan game that runs on 2 Adruino boards. Two Arduinos (that talk to each other) were used because a single Arduino would
You probably remember (and have) the Texas Instrument MSP430 LaunchPad, that is the TI microcontroller development board that was released for $4.30. TI is back at it, they have just released their C2000 LaunchPad which has a 60MHz Piccolo processor on board. This processor is sure to be very popular based on the power and price since it looks like you can get them for 2 or 3 bucks
How many hits does your web site have today? You just need to log onto to your stats system, drill into a few menus and voila there it is. This ATtiny USB Web Site Hit Counter Project by Bob Hobby makes it much easier than that, you can just have a look at the numbers on your own hit counter panel, if you are curious how traffic changed based
If you enjoy a beer or two every now and again you might want to try your hand at making a few batches of your own. After you get good at it why not automate the process. That is what randyrob did and has since had his system make over 1000 liters of beer. Got to love the NES controller that he integrated into his control system! Best of
This Kickstarter will get 1000 Ping Pong Ball Projects into Space. Many of them will be student projects but there will be a bunch from non students so if you have a great idea you might be able to get it into space. There are some cool sponsorship levels such as getting a note into space and back for $10. I was wondering how many they recover since they
If you have a camcorder you have probably had a case where you needed to start recording but weren’t near the record button. Ragtop from the Parallax Forum built a DIY Voice Activated Video Recording Project that monitors the room noise using a small microphone. When the room sound level is high enough the system sends out an IR code using an IR (infrared LED) that simulates the record
