Building a home made G-meter

Accelerator meter
Jesper writes on his page about his AccelR8 project:

This is a fun project. Unfortunately, it takes some time to develop the code, so this is a work in progress and here i’ll just present the project so far.
Basically the AccelR8 is a device for measuring acceleration. It can measure +/- 2 g.
As it contains a microprocessor, it an also measure time.

AcceR8 will tell you :
Acceleration 0-100 km/t (0-60 mph),
Braking distance 100-0 (60-0), and
Maximum Horsepower

Maybe not something you’ll do in the coffee break but have a look at the AccelR8 project

Soldering like an expert

LED organ
A organ (when you speak electronics) is a device that flicker and blink a couple of lights in motion with music or other sounds. This is such device and there are two things that are interesting with it. The first one is of course how to build one and there is a piece of schematics on the linked page where it’s described in detail how you would go about to build one.

The second one is just the looks of it! It’s built like a birds nest, which is quiet common when you build small things - not when you have hundreds of components on such small space!! None the less it’s very impressive. Very!

Custom made L-pod for slim cameras

by @ 9:47. Filed under News
To make something useful doesn’t always have to involve rocket science - that’s something I’ve said before and I’ll say it again. Papydom has a small compact camera that is nice and thin, which unfortunatley means that it lacks a proper hole for a tripod mount. He writes:

I love my Sony DSC 7 camera. It is really thin, and I can finally go to a wedding or a family party with a camera in my pocket and still have a straight jacket. The point is that it is so thin you cannot screw a regular tripod in it. You have to use an adapter that looks like a big socket for the camera, and accepts a regular tripod screw. This adapter is not heavy, but it is too big for my pockets. So I decided to build my own accessory. I call it the “L”-pod, because this is its shape when in use, as you can see in the last pictures.

Computer in a whisky bottle

by @ 16:15. Filed under News
I’ve seen a lot of great custom cases during the years but I think this one beats most of them. Janos Marton took computer casing to a new level with his computer in a Ballentines whisky bottle.
It’s not extreme in terms of either power or performance but it fulfills its designers wish to be small, handy and quiet as he already has a powerful computer when that’s needed.

DIY T-Shirt folding machine out of paper

by @ 4:16. Filed under News

I’m very bad in folding t-shirts. Plain and simple, it takes me forever to fold a t-shirt in what my wife considers a proper way and she usually comments my folding with But - it’s so simple.. Well, I just don’t have it in my fingers and if you’re anything like me then you will appreciate this instruction video on how to build a t-shirt folding machine.

God - it’s so simple when you see it. [click on the image to play]

DIY Led flashlight

by @ 11:06. Filed under News
LED Flashlight You can buy these LED flashlights for not to much money, but why buy one when you can build it yourself? The benefit of using LED’s instead of a regular glowing lightbulb is of course its efficency where about 90% of the energy is turned into light comparead to a lighbulbs 10%. With these LED’s consuming about 90mA you should be able to use this flashlight for about 25 hours before it’s time to charge or replace the batteries.
As this curcuit needs 3.3v to function there is a IC taking care of the stepping up of the voltage from 1.5 to 3.3v. And no, you can’t pop in more batteries as we’re talking a pocket flashlight here.

DIY POV

by @ 9:28. Filed under News
POV LED Clock For being a beginner in working with clocks I must say that Bob has succeded very well. This is a POV, Persistance of Vision, clock that works like this:

A motor spins the “propeller”, and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion, but it works nicely. If you want to build this clock, you will need a few things, including: Skill with motors and mechanical things. Prior electronic experience. A dead VCR or floppy drive or other source of a suitable motor and miscellaneous parts. A programmer that will program a PIC16C84 or 16F84 microprocessor.

Contest: Run Windows on a Mac

by @ 9:21. Filed under News
100 dollar Colin is convinced that XP can be run on the new MacBook that starts shipping on the 15th of February. They’re intel based for anyone who has missed the news flashes. He’s so convinced that he’s holding a competetion on who will be the first to boot the mac into XP.

I am pledging $100 of my own money and offering anyone else who would like the instructions on how to Dual boot these two operating systems the ability to donate some of their money into the pot as a reward for the person / group that can make dual-booting Mac OS X and Windows XP happen on an Intel Mac. Good Luck, Colin

At the time of this writing the total donated price money is $9842
Want to go for it? Have a look at Windows XP on an Intel Mac
