$17 Arduino-based nikon IR intervalometer + code


This is one of those projects I’ve been working on for quite a while now, but never well enough to actually put it in a box! Well.. it still has no box, but it’s much closer to a boxable form.

It is a RBBB arduino clone (but any arduinowillwork) with an ir led, a potentiometer, a resistor, and some perfboard. The perfboard is as much there to help provide a little bit of wire strain relief as it is to provide a place to mount the pot. The code simply reads the pot input and converts it into a delay() function. Then it fires the IR led with the nikon-specific magic to tell my d40 to shoot.

Here is an example of one of the timelapses I have shot.

Hackintosh one month review: Hp mini 1000

Hp mini hackintosh

I have had my little hackintosh for almost exactly a month now. I saw how the wired editors soured on the idea of their tiny notebooks, and I figured I would check in to share my experience.

CD robot V 2.0! Adding serial control to an old scsi cd duplicator.

My newest project involves reincarnating a very old (1998) cd duplicating robot. It is a DTP-1000 that was originally SCSI only. Due to the fates smiling down upon me I was able to pick it up on ebay for $11. I bought it intending to put an arduino in the place of the control board and probably have to do a lot of reverse engineering. The next day I happened upon this site where, amazingly someone has already opened one of these up and has instructions on how to enable serial control! I still am in awe of how lucky I got and really happy that DarkBane dropped all of that knowledge on the world.

There are a lot of pics below, since that was the one thing I could do to add to the fine directions DarkBane has already provided. Another thing is that in his command set he has two typos. I will quote his post after the pix and note the command set in bold.

Lethal Pneumatic Ping Pong Ball Gun.

Ping pong ball aftermath

I just moved to Colorado, and being new to the area I was really excited to find out that there is a Denver maker’s meetup. For those of you who don’t know, a makers meetup is where inventors and fans of Make magazine get together and talk about their inventions, ideas, and plans. It is held at a hacker space called Club Workshop on the gritty side of denver. The shop is amazing! I didn’t even get a tour, but I saw a full woodworking room, a metal shop, a multi-lift automotive shop, a small textile area, and their laser cutter. This place looks like the kind of place I could definitely spend some more time.

The meetings are loosely structured, and the point is to bring and show other people what you’ve been working on. This particular meeting was largely filled up by Ron Kessinger. He is an artist/inventor/sculptor/prototyper and even that description doesn’t even begin to properly describe him. He brought a big binder filled with photos and sketches of his previous creations. He had pictures of the giant dome house he built, really cool collimated flow water sculptures, knives, and prototypes for a variety of industries and products.

The project that really took center stage was his ping-pong ball gun. You can think of this as a variation on a potato cannon, however his is built to run on compressed air, and it runs on much tighter tolerances.
