Fantastic RGB LED coat!

mowcius — Wed, 29 Sep 2010 19:48:06 +0000

This coat by [DustMonkey] had to be one of the most colourful things at burning man this year.

With 256 LEDs each individually addressable in a 32×8 matrix, it’s a lot of wires!

[DustMonkey] had about 300 mini PCBs made, one for each LED with a 4 wire header on each one to make the wiring simpler. All of this is controlled by 6xTLC5940s and a 595 Shift register with an ATmega328p (arduino) doing the work.

The final result really is very nice. I know I would love one of these in the coming winter months.

Starfighter Helmet LED Mod

Who says that arduino projects have to be complex?

This mod of a Starfighter helmet [Ian Cole(digitalman2112)] made for his son is just that, nice and simple. [Ian] added some LEDs in place of the fake lights on top of the helmet and a modified Pico Arduino to control them.

Yes, people will say that an arduino is overkill but it’s quick, simple and easy to add to in the future if required.

It’ll keep his son happy and make it safer to walk around in the dark. It’d be a great design on a bike helmet.

Build your own Ultrasonic Range Finder

[majolsurf] has posted a rather neat home made US range finder up on his site, majolsurf.net

Unlike commercial devices; this is cheap, easy to configure to exact needs and will give you the full reflectance pattern (not just the distance to the closest object).

I know I will be trying something similar in the future, I am rather a fan of the maxbotix sensors but they are rather expensive and the full reflectance pattern could be very useful.

Equinox Clock

Don’t know about you but I love this clock, even more so when I know it uses an arduino.

When I first saw this on my google reader feed, I thought it was one of the design websites I have a feed of but I was pleasantly surprised.

You can read more about it here.

I wouldn’t normally add so many pictures but it really deserves it!

Timelapse Controller for Canon DSLR

mowcius — Fri, 03 Sep 2010 09:57:50 +0000

[-Gil-] has done a nice neat timelapse controller for his canon DSLR, it consists of:

an arduino mini pro
2 optocouplers (4n35)
an LCD (HMC16223SG – controlled by HD44780)
three push buttons
two LEDs
and a neat project box to keep the wiring spaghetti hidden away

The results are very nice, here is an example cloud timlapse video, taken at 1 frame every 5 seconds and played back at 15fps.

High Altitude Balloon Photography

These projects are always something I like reading about and something I long to do some day.

Just look at the kind of pictures you can get (click for full size):

This one is the handiwork of [Timz] and he has done a great job.

Excluding the radio receiver and the borrowed items, this does not seem too expensive especially if you have a few of the components already.

The radio and GSM and dual GPS might seem a bit excessive but having a bit more kit is better than losing your balloon and all the expensive payload.

If you are going to do a similar thing then make sure you check up on the cellular network regulations for where you are, some countries disallow the use of cellular devices when you are not on the ground so you would only be able to use the phone when it had landed.

Go read more about it on his website

I didn’t intend to to do this originally but I feel like having a go.

I see so many arduino projects around and they are never all in one place so I thought, why not make it so!

Hopefully I will be able to keep this up and get them uploaded into a list on the duinoaday site too for easy access.
