Running down netbook batteries

We normally put these back on charge as soon as students return them. Over the summer we are running the batteries down completely before charging them again. We’ve recently regained this room which is being set up as a dedicated AV room with storage and charging of netbooks, laptops and ipads, along with a colleague’s digitisation project.

It’s finally more-or-less finished!
All I have left to do is fix the laptop-half onto the back of the frame more solidly and find some rubber feet so it doesn’t sit on the wall at a slight angle.
So glad I ditched the first attempt and used my other junker laptop instead, it’s worked out so much better and fits on the back of the frame in such a way that if I liked I could keep the battery and whatnot in and can keep the bottom half of the laptop shell on to protect all the bits. So nice.
It was running Twittervision but now it’s got surveillancesaver on it.
Geode-based Neoware Thin client running on Linux and 4 AA Batteries!
Image by Extra Ketchup
I have a few of these Neoware thin clients laying around ( www.flickr.com/photos/extraketchup/2292764032/ ), and because of their single 5 volt requirement and low power consumption, I figure they would be great for robotics projects and other such cool things!
With a power draw around 5 watts at idle, I can run this computer (sans case and P/S) off of 4 AA batteries!!
The unit comes with about a 130MB SSD (solid state drive), which isn’t much at all (it has old Win CE on it). However, I was able to get a bootable Linux install on it with various tools I would want for robotics (networking, Python programming language, USB storage, USB cameras, serial and parallel port access, etc.) I used Gentoo to fine-tune my install to this specific hardware.
Check the other photos for some more details about this project. Check out www.flickr.com/photos/extraketchup/2280376584/ for more details from back when I started this project (which has been on the back-burner for a while).
…is a recalled battery…

The Apple battery IIc was designed to be portable, and since it is powered by 12 to 15 volts DC, it can be run on batteries. A 12-volt sealed lead-acid “gel cell” battery works best, due to the high current draw. I also show the pinout of the IIc’s power supply connector, and demonstrate an unusual BASIC program which generates musical tones on a nearby AM radio, rather than through the computer’s own speaker.

boginjr.com A five-year old laptop made “portable” again…. You surely know that Li-Ion batteries won’t hold their charge after two or three years. Why pay 90 EUR for a new battery pack? Just a quick voltmeter setup, a cordless drill battery and we’re off. Just make sure that the battery voltage is over 12V, or else the laptop may behave irrationally. (NOTE The battery used here is a Ni-Cd type, rated 14V 1.2Ah; however the capacity of 1.2 Ah is NOT enough for this setup. You need at least 3-4Ah to do something useful – my battery did last just 30 minutes, the voltage then dropped to 10V and the laptop froze due to undervoltage.)
