How-to add internal USB to your laptop cheap

by @ 13:14. Filed under Hack, Projects, Wireless
Disected USB dongle
Bluetooth is cool but unfortunatley I don’t have it build into my laptop. There is an empty mini-pci slot available but after trying to find a good Bluetooth card to put in there without spending a fortune I simply dropped that solution. And using one of these dirt cheap USB Bluetooth dongles is a hazzle as I don’t like having that sticking out of my laptop the whole time.
Well, why not build it in as Tom did! I’ve seen this kind of projects before – but this one really only uses a Bluetooth dongle plus some cables. No hub or any other electronics so it’s actually a no-brainer to get this one working. That is as long as you have the space within the laptop to hide the dongle away…

Circuits that come in handy

5v regulator
While designing all kinds of different curcuits I usually pick the designs from my head, or I go seaching on the net to find what I need. Over at DIY Live they put together a good top 10 list of curcuits that often come in handy. Like a 5v regulator, how to drive a transistor as a switch, USB pinout, a simple amplifier and lots more.

They write:

I have decided to compile a list of the top ten most needed circuits that are a must know for anyone interested in DIY projects. These are the basics that can all be interchanged and used in conjunction with each other to make many of the projects that we all love so much.

Charging you iPOD in different ways

by @ 16:40. Filed under News
iPOD bicycle charger
When I leave my house I always make sure that my iPAQ (don’t have an iPOD) is fully charged and ready for a full days work. I also have a charger in my car and in my office so even though I might forget to charge it during night this is not really a problem.
Mark though, he realized that these options not really are sufficient while riding his bike or while out camping and therefore he developed the ‘Hand crank charger’ and the ‘bicycle charger’ for his iPOD. Both are based on a hand crank flashlite.

Force feedback racing simulator

by @ 21:04. Filed under News
Force feedback racing chair
Do you want to build something that scores 9.5 on the geek scale? Wanna have a ‘real’ force feedback simulator that is as close to the real simulators as possible?
Then have a look at Jared’s little project where he uses the classical ingredients as a stearing wheel and the standard pedals, but also a electrical winch for a car…

He writes:

I remember when I was younger taking a family trip to Universal Studios Hollywood. While the experience was overall a snore, there was this one ride that really captured my imagination: Back to the Future. For those who don’t know, its a Delorean simulator with a back to the future theme. … For some time I have wanted to make my own, seeing the NASA shuttle simulator and other similar training simulators all over. Well one day while playing mech 4 I realized that I had the power to do so literally in the palm of my hand. So I decided to mod out my simulator. Well a lot of
R & D went into this and this is actually a prototype for the main build to come.

Thanks Tom Needer for the tip!

Simple but powerful bench power supply

Power supply
I find myself in my garage way to many times in the small hours of the day trying to find a suitable power supply to power what-ever-I’m-doing at the moment. And everytime I do this I look at an old atx power supply and thing – Hmm, I’ve got that 12v there… but…
But of course someone has done this for you already and have a look at this if you need a small project to hide yourself away with during the long christmas dinners coming up. It should take about an hour or two to complete and you get a ps that can give you +5,+12,-5 and -12. Connecting between +5 and -5 will give you 10v and so on, so you also get +7, +10, +17 and +24 to play with.

Extreme macro on a budget

by @ 20:27. Filed under News
Macro photography
In all pictures for my projects (and other photographs also) there’s always that moment when I need to take an close-up on something exceptionally interesting, like a ball point pen… On my Canon S40 (compact 4mp but still good) I have this feature which lets me snap a picture as close as about 10cm (~4 inches) which is usually sufficient if you take the photograph in high resolution and then crop it down. But it could definitely be better, like as on this picture.

Hajejan took this a step further – on a budget. He has a removable lens on his Canon EOS which is not something that I could do so maybe it’s time for me to get a new camera? To wrap it up (aka spoiler) – he mounted a Pringles can in-between the camera and the lens which allows it to get into real macro.

Hacking santa

santa claus
This is something I’d personally would love to have standing in the hallway during christmas to welcome all my guests.
Josh writes:

If you’ve ever gone to Wal*Mart during the Christmas season, you’ve seen it. I figure that at least a quarter of the US population has been exposed to it by now. A 5 foot tall Santa Claus that sings and dances to holiday music. Head moves left and right. Mouth opens and closes. Body sways from side to side. They’ve got white Santas and black Santas. Around here, they even have Spanish speaking white Santas. But do they have… hackable Santas? It took me $49.84 to find out.

He has several videos on his site where you can hear and see the hacked version in action.

Line following robot

Line following robot
Greg starts with warning us for a long article in this DIY article. And while we’re at it have a look at this one also over at ELM, it’s really small and neat.
He writes:

…we will start out with a problem and a solution. The problem is going to be to build a Lego robot with sensors, a motor controller, and a microcontroller that 1. Follows a black tape. 2. Upon reaching the end of the tape will pause for three seconds. 3. After pausing for 3 seconds will return back to the starting point.

DIY Snow

Snow machine
Making snow is always something that seems complicated but after reading this article about on how you can build a snow machine yourself I must say it’s something I’m definitely will try when (if) it finally goes below zero here.
The article itself is very straight forward and I myself have several question marks after reading it, but it’s a starting point. I’ll let you read it for yourself and draw your own conclusions.

The real hard drive clock

by @ 12:01. Filed under Hard drives, Projects
Hard drive clock
Hard drive clocks has been around for as long as hard drives has been around. The first ones simply had a disc and the regular hands, the second generation had a whole hard drive and regular hands, and I’ve also seen a very nice one which is using light and a spinning disc to show the time. But except for the last example they still look like a clock with those plastic hands.

In part 3 we take a look on how to build The real hard drive clock. Even though this clock might not fit into every home, it definitely has something about it that makes it nice to look at.

Read about how it was done in The real hard drive clock
