Wifi Enabled Outlet with VoCore

We have an older Mr. Coffee without all that newfangled technology like a clock and timer which means getting out of bed to start the coffee pot. How can one turn on a coffee pot without leaving the warmth of cozy sheets? Add a VoCore, some LED’s and relays to a surge protector/USB charger, that’s how.

Z2 Breakout Testing Part 2

After fiddling around with the two breakout boards I’ve assembled, I think I’ve got everything the way I want it. I’ve made some new useful changes as well as fixed the issues I described in my previous post. The remaining parts needed for the Z2 Breakout relay header arrived today and all is working there. I also did some current testing tonight and thought I’d share the numbers.

3.3V to 5V Boost Converter for Low Power Projects

Quite a while ago I built a USB adapter for my Zipit based on the Texas Instruments TPS61240 boost converter IC. It’s a small chip and only needs 3 external components to function. The ouput current is limited to 400-450mA but it runs most low power USB devices just fine (flash drive, mouse, webcam). It also has a wide input voltage range of 2.3V-5.5V. This makes it a great boost converter for low power / battery operated projects so I decided to design a breakout board for it.

Give Thanks for Zipit Breakout Boards

While most Americans were probably eating turkey and watching football today, I was eating sushi and finishing up the layout on a Zipit breakout board. It’s been a long time coming. Hopefully it’ll be here before Christmas.
