Binary Clock Build

at 9:44 pm. Filed under Electronic Hacks

This Binary Clock Build project by JD is enclosed in a custom acrylic enclosure. 3 buttons are used to adjust the time, the binary clock is displayed for your leet friends. For the regular folk there is also a time display on the LCD. The System is powered by a Parallax Popeller. With 40 pins the Propeller has enough pins to drive each LED direct, the buttons are also all connected direct. The LCD is a serial LCD so that just required one data line but there are still available pins so chances are a standard LCD would also work.

Coin Cell Jump Starter Project

at 11:34 pm. Filed under Cool Gadgets, Crazy Hacks, Electronic Hacks


 

Ted Yapo is designing a crazy project idea, it is a Coin Cell Jump Starter! Just think next time you need to jump start your car you simply need to locate a coin cell and use this system to suck the power out in a usable way to start you car. Is it practical? Not really but it is cool is this theoretical idea would work. It is a total work in progress, I am looking forward to seeing a video of a car starting soon.

“So, if I can create a boost converter to charge the capacitors to 14V from the cell that’s at least 6527/10800 = 60% efficient, I should be able to start a car from a coin cell.

The first rough plan is to make a simple inductor-based boost converter to charge a similar (possibly identical) capacitor bank over perhaps 24 hours, then start the car with the capacitors in place of the usual battery.”
