There’s a lot of hubbub on the internet about charging Lipo batteries and how dangerous it can be. It can be, but if you take some precautions it’s perfectly safe. Charging Lipos safely typically requires specialty IC’s to ensure they don’t explode. All devices with Lipos (smartphones, tablets, laptops, etc) have these charging chips built in to protect the device and the consumer from an oops. The batteries themselves also contain a protection IC. The IC’s are great but can be over protective. I often get phones and tablets for repair with “bad” batteries that just need a little coercion into working again.

About three years ago I picked up the Harbor Freight 45 Watt Solar Panel Kit with good intentions. The kit was on sale (I think ~$130) and I figured, “why not? This could be a great backup power system.” Unfortunately, it’s not great and it’s no good as backup power for much of anything most folks would use it for. It does, however, provide some electricity and I figure I should use it. After the purchase I fiddled around with it, then put it away until this spring. I decided to give it another go and challenge myself. My goal was to not plug my cell phone into a wall charger for as long as I could.

A few years ago I looked around for a way to have the Zipit play console beeps and found some ways but could never get them working. The other day someone in #zipit reminded me about those beeps so I looked again and found the Fancy Beeper Daemon.

It’s official, Zipit breakout boards are here. You can order yours in the shop I’ve setup. My previous posts about the design process have some info about the board’s functionality and some issues that needed fixing. This post is intended to bring all the info to one spot and explain how it functions. Any new information will be added to this post.

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.
