ACT3: USB devise charger - build with stuff I had at home

So I was inspired by this iPod charger posted by TJ Roshan - and I thought 'I can do that with the power connectors I have around the house and in my car.' So here is what I created to charge my iPod (or any USB chargeable divice).

These were components which I had - I simply had not put them together this way. First an Apex hand crank radio / flashlight ($14US). As you can see this flashlight actually came with a attachment that allows one to charge external devices using a "cigarette lighter" type attachment (see detail picture below).

I plugged a Griffin PowerJolt Dual Universal ($15US) USB adapter (an adapter I purchased for my car) into that device. From there I can plug any USB connector and charge any USB device that I own. In fact I can charge two devices at one time. This is great because I own a few. As you can see I attached my iPod and it worked. Here is how I know it worked.

The battery on the iPod that I connected was complete drained (it would not turn on). I plugged the iPod in and cranked the crank for five minutes. I then played music on the iPod to find out how long it would play with only five minutes of effort on my part. The iPod played for 1hour and 25minutes on the charge! Very nice.

That's brilliant, James! Thanks for that post on the Barefoot College, too-- a big inspiration. I have very little in the way of technical skills, but I would love to build a reprap. Between your descriptions of what you've put together and the inspiration of the Barefoot College, teaching illiterate grandmothers to be solar engineers I'm hopeful that I'll eventually manage to make something useful.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
