I was recently looking at Microchip's PIC10F322 microcontroller and thought it was a very capable little MCU for its price (and size). It has some really interesting peripherals onboard, like the Configurable Logic Cell (CLC), the Numerically Controlled Oscillator (NCO) Module and the Complementary...
I'm playing with a new flat-file CMS called Grav, and building a new site with it. I've had my fill of the giant database-driven CMSs like Joomla and WordPress. They're good for what they're good for, but for my dinky little site they're just massive bloatware overkill. I'm looking for simplicity....
In a recent Ebay China toy order I grabbed four HY-SRF05 ultrasonic rangefinder sensors to play with. Can't beat the price at $1.89 USD each with free shipping. They'd be dirt cheap at twice that price.
Here I'm controlling the SRF05 with a PIC18F2680 and displaying the results on my "Predko" 2-wi...
Ever since I was a youngster I've always wanted an oscilloscope. I didn't know much about them, but I knew that every electronics lab has them and they looked like they must be a good thing to have. Several months ago I finally broke down and decided to go oscilloscope shopping. I ended up with a Si...
So I drew up a board for the Silicon Labs CP2102 chip and made all the improvements I wished I had done on the CP2101 board. Great little ICs. I drew the board much more compact this time and left off the unnecessary extra pads. Once again I had the boards made at DorkbotPDX and as usual they came...
