Acc_Gyro = Accelerometer + Gyro Chip!

For those of you looking for an accelerometer chip with a gyro, look no further as this new Acc_Gyro chip does exactly that.

The Acc_Gyro Board represents a 5DOF Inertial Measurement Unit (IMU), capable of measuring acceleration on all 3-axis as well as measuring rotation rate around the X and Y axis. Combining values from both accelerometer and gyroscope will allow you to obtain accurate values of inclination angles relative to the earth’s surface. IMU units are often used in

Well, we just bought the Vex Robotics Kit for like a hundred bucks at Radio Shack while shopping for some parts. Check out the video of what’s inside the kit. Apparently, they are not selling too well at Radio Shack but the kit itself is a great deal and has lots of parts for other projects.

We couldn’t help but to open up the microcontroller box (spelled mirco controller on the box…) and found the PIC18F8520 is powering it. I think we might be

DIY HACK – Oscilloscope using PIC

http://zedomax.com/image/200701/more-pic-oscilloscope.jpg

Here’s a cool DIY oscilloscope using a PIC12F675 kinda similar to the Atmega Atmel Oscilloscope.

This is a simple PC voltage oscilloscope using only a PIC12F675, a 20MHz oscillator, and a RS232 level shifter. The PIC takes a sample on GP2, immediately sends it to the PC at 115,200 baud using an software asynchronous serial routine, and repeats. It sends a 8-bit val

DIY HACK – “Propeller Clock” Mechanically Scanned LED Clock

http://zedomax.com/image/200612/cool-pov.jpg

Cool propeller clock you can make!

How this clock works: A motor spins the “propeller”, and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion, but it works nicely.

If you want to build this clock, you will need a few things, including: Skill with motors and mechanical things. Prior electronic experience. A dead VCR or floppy drive or other source of a suitable
