Just like cars that measures the distance it can travel, you can also do it with your bicycles. We usually keep track of our mileage to see how far our strength can go but would it be of great use if we track it because we are maintaining a workout everyday considering the calories ...

emonTx stands for Energy Monitoring Transmitter.

It’s a small wireless energy monitoring node. It’s designed to take inputs from multiple CT sensors, optically from a pulse-output utility meter and from multiple one-wire temperature sensors. It is designed to be powered by 2x AA batteries or 5V USB.

Dmitry Grinberg had a few PIC12F1840 MCUs lying around, and wanted to use them in some type of IR remote control project. He decided to construct a remote control mood light using the PICs in both transmitter and receiver. Four high-brightness LEDs (White, Red, Green, and Blue) are used to combine to form different colors in the receiver unit housed in a jar, along with a 38 kHz IR receiver module. The commands are generated by a PIC (housed in a gutted remote control housing) and transmitted via IR LED.

This solar garden/path light was found at Target for $3! Nothing special about path lights, and the low price is no surprise in our times but this item looks very interesting for home projects. Instead of the fancy curved “good looking” enclosures it’s a simple cube. Very easy to reuse this enclosure. Reuse the enclosure, rip out the guts and build something cool. Use the Led, Battery, and the stake part to mount and power your latest creation. These kinds of things inspire me. I am compelled to find something interesting to do with it.

A 5-wire unipolar stepper motor (these could also be salvaged from old 5¼” floppy disk drives), ULN2003 IC (stepper motor driver), wire, stripboard (or a solderless breadboard ), solder and DB-25 Male connector (buy these two if you can solder. Soldering is not necessary for doing this project, but it will ensure that your connections are secure), DB25 (female/male) parallel port cable, a multimeter, a power adapter (with voltage rating depending on your motor’s requirements)
