Get Your PET Out Of The Cemetery
Continuing with the idea from last year’s special Halloween edition, here are some ghoulish ideas to take this year’s haunts up to the next level — electronically, of course!
Go retro with this PET project that will get you re-learning everything about these old machines.
To the Power of I2C. We’re going to raise the bar and connect our AVR microcontroller to modules with a little more intelligence.
It seems like just an innocent edition sitting on the counter ...
Give your Jack-o-lantern (or whatever props you may be using) some cool faux flames this season.
Get those talking props in sync with this audio spectrum analyzer that has a variety of uses — from tone detection to real time audio analyzation for controlling servos and other devices.

RF Interference
RFI is everywhere — is it interference to you or is it interference by you? Possibly both! But fortunately there are ways to keep it in line.

Take Your PIC of a Super-Fast Embedded Computing Machine
It just doesn’t get any better than this. It’s time to gather the components, get the circuit boards made, lay down the parts, and write the code. When the dust settles, you’ll have built a super-fast 32-bit embedded computing machine that can converse via multiple logic-level serial ports, a true RS-232 port, USB, and Wi-Fi. If all of that data is important to you, just store it away on the onboard microSD card. And it does get better.
