DIY HACK - How to make your own open source motor controller!
Check out this cool little hack, it’s an open-source motor controller for an electric bike. There’s no pictures of a finished version but can’t wait to see this circuit in action!
n brief the PicOx is a PicAxe 08M based digital Controller that performs an ADC of a Hall-effect throttle and an ADC of a Hall-based current sensor. These two parameters determine the “Mark” value of a 15Khz PWM signal that does the switching to the Output stage. At the end of the project the Controller can sustain 48V @ 75 Amps repeatedly for approx 5 second bursts and is really only limited by the In-Line breaker that cuts the supply voltage, though the entire system’s overall design objective is met reliably at 48V 50Amp operation…

Loading ...Download Windows Movie Maker for your illegal Windows XP, Vista, whatever!
When your computer dies and you don’t have a backup disk of your official Windows that came with your computer, you do have to resort to other ways such as installing an illegal copy of Windows XP. Well, that’s what I had to do since I do have an official license but no disks that came with my computer.
Well, I use Windows Movie Maker to make most of my videos and it’s a great video software that doesn’t break down.
I try to download it from my illegal version of Windows but I have to do a “Windows Update” in order to get the Movie Maker, which I hate to do and most of the time it tries to install this “Windows Genuine Checker” thingee.
Well, to download the Movie Maker without going through those Windows Updates, you can simply go here.
Wish Microsoft just made everything open-source and free, otherwise honest and good users like me don’t have to resort to illegal ways to get the software that I need.
Yes, the biggest problem with Microsoft is that they SHOULD offer online downloads of their operating system by simply entering the OEM product code. That will help me save a lot of time trying to find illegal ways to get what I paid for working again.

The Google phone or is it gphone is due to hit the streets by June 2008, and it would appear that the phone and everything about it is going to very different to what we would have expected from other phone providers.
For once the software or part of it is going to be open source, this will enable outside developers to work on their solutions for the phone, which is great and will offer more opportunities for users to find different applications for the phone.

Wow, check out these chumbies, wifi enabled touch screen. Hmmm. If they came out with a Chumby phone, I’d get one.
“chumby is a small, wifi enabled, touch screen information device. When you take it out of the box and plug it in it is essentially a glorified alarm clock. But when you take a moment and register your particular Chumby at their website, it can become just about anything you like. A number of widgets are available now and can be enabled on Chumby with a click. And Since Chumby is completely open source and has made a HDK and SDK available for developers, expect modifications to come quickly.”
