Make Controller Kit
MAKE Flickr photo pool member DDaniels has some photos of our (now shipping) MAKE controller kit & some experimentation with it... here, the MAKE Controller Kit with a scavenged talking mickey mouse servo. It uses a pontetiometer to determine servo position, and uses PWM output to drive the servo motor. [via] - Link.

Add a LCD to your PC (USB)
Nnod has a follow up on our previous "Add a LCD to your PC" post, this version uses USB... - "If you're a little more adventurous you can build your own USB LCD interface with a PIC or AVR microcontroller. It's not as scary as it sounds. This is good because you can power and drive the unit all through one USB port, and it's the only option when you don't have a serial or parallel port. I did this with a PIC18F2455 and it worked out quite nicely." [via] - Link.

HOW TO - Make a Kid's "Draw Bot"
Finkbuilt has a great draw bot that's not only a great project for kids, but adults too! Steve writes - "As far as I'm concerned, you're never too young to start mixing art with robotics. So, next time you and your budding young tinkerers need something to do on a rainy day, you should have no trouble scraping up the parts to put together this crude, drawing robot project that we saw at the Seattle Robotics Society Robothon." Thanks Windell! - Link.

Simmons LED display
Here's a really bright building based Luxeon LXHL-LR3C Royal Blue LED system with schematic and code included... A MAKE reader writes... - "A giant 2-story-high LED display was constructed using amazingly powerful Luxeon LEDs in a 6x6 grid of windows at the architecturally renowned Simmons Hall undergraduate dormitory at MIT. It's a fairly simple circuit design that anyone can do with a decent amount of patience to wire each pixel." - Link.

HOW TO - Make Halloween "cave eyes"
Cowlacious Designs shows you how to make "cave eyes", schematic, code, circuit board layout, and parts list included or you can buy a kit/complete unit... - "This is a little microcontroller circuit that has 15 pairs of L.E.D.'s that look like rodent eyes. The pairs of eyes blink in a semi-random fashion. So, what you end up with is 15 pairs of eyes staring out at you with one pair blinking (looks like the animal had to close their eyes briefly) at a time. The pairs of eyes are on wires so that they can be placed around the cave, bushes, etc. Runs off of 4 AA batteries." [via] - Link.

DIY Hovercraft with 4 PC fans @ 22V!
Max writes - "Okay, yesterday through the instructable, we made a simple hovercraft. Today, we are going to take it to another level by taking FOUR PC fan coolers and running the FANS at 24VDC instead of the 12V DC rating. I think they are okay up to 30VDC, well, our fans are still running..." - Link.

Hacking your car radio - aux input
Nilson writes - "I have a Pioneer DEH1850 car radio system.. it's Pioneer's cheapest new model.. no mp3, no blue lcd, no ... But, I have an iPAQ rx3715 which I use as, mostly, an mp3 player (though I get some matlab stuff done in it too). So, I figured: why not jack an extra input to the radio and plug in the PDA? So, this is what I did" - Link.

Cheap BOE-BOTs
Tonyvr writes in with this deal on BOE-BOTs - "Cheap BOE-BOTS are back at MicroCenter again, but at $70 instead of the previous $50. This is still a terrific deal, as list price is $149. I bought 20 kits at $50, and although the boxes were battered, and had "Radio Shack" price stickers on them, the contents were new and complete." - Link.
In August we pointed to this when it was $50, as Tony said, it's not a bad deal for a Boe-Bot Robot kit (uses a BASIC Stamp 2 microcontroller).

Shocking alarm clock
Clinton made a shocking alarm clock, literally, he writes - "The idea for this project came to me about a year ago, it was right around the time I made the homebrew handheld shocker. I wanted to make something that I could shock my unsuspecting friends with and yet have it still be very annoying, and that's how I came up with the idea for the shock alarm clock." [via] - Link.

HOW TO - Cloning a Verichip yourself
Jonathan Westhues has a how-to on cloning your own Verichip (schematics, parts list, gerber and source available) he writes - "I used a relatively sophisticated piece of electronics to clone a Verichip. This made things trivially easy. Even though I had never seen a Verichip before in my life, I just had to write a hundred lines of code; but because I used my proxmarkii, I've heard claims that it is impossible to talk to a Verichip without expensive equipment.
Also, I embarrassed myself in front of a documentary crew when I couldn't clone the Verichip that their presenter had had implanted. (He was a fairly big guy, and the chip was very deep beneath his skin, so I didn't have enough read range to do it with my proxmarkii. We tried shoving the antenna into his arm, but I think we just pushed the chip deeper. A proxmark3--which can read them at the correct operating frequency of 134 kHz, instead of 125 kHz--would have worked fine, and in fact I had brought two of them; but I destroyed both, through my own stupidity, before I got a chance to do the demo. If you build a proxmark3, then don't forget to populate D10/D11.)
I therefore wanted an inexpensive cloner, with decent read range and a simple user interface. It should be easy to build, and it should not require a PC to operate. This will make it easy for you to clone a Verichip yourself, even if you don't have a lot of money, or any knowledge of electronics. The device will also be simpler to use, and have fewer parts to fail; if more journalists have chips implanted, then this reduces the chance that I will screw up the demo for them as well." Thanks Annalee! - Link.

Fun with micro-controllers!
MAKE Flickr photo pool member Steven and Sarah write - "Exploring micro-controllers with the Arduino NG development system. Seen here running in standalone mode with a 9V battery. Arduino makes embedded programming fun and easy by bringing together a clean and simple hardware and software development environment.
Here, I'm messing with reading analog input from a 10k potentiometer and PWM (pulse width modulation) of leds to produce variable brightness." - Link.

Solid-state Halloween controller and HOW-TO build a Haunted House
Eric over on Instructables reposted his Halloween controller and haunted house how-to along with some more information - "This was originally an article in Make 03 where my awesome editor Paul Spinrad actually made a replica of my controller and did a much better job documenting it than I would. For the controller board, if you need more explanation than "get a bunch of solid-state relays, connect them up to your parallel port, and go to town," check out the Make article. It also has an awesome comic that I have gone to pains trying to convince people that it doesn't star me.
With this Instructable, I'm putting in text that didn't make the cut for a size-constrained magazine article and creating a space to explore the latest options for computer control. The Win98 machine I had previously used to drive my controller can no longer by relied upon and I haven't yet conquerred external (parallel port, serial port, USB, ...) control with WinXP or MacOSX; hopefully we can collect some great pointers and links in the comments." - Link.
If you're planning something like this for Halloween, pick up MAKE volume 03 here and/or log in if you're a subscriber (digital) edition and check it out.

Remember those awesome color changing LEDs on a string? John has a video review of them, he writes - "I just uploaded a much better quality video of the Triklits set I bought from www.triklits.com a few weeks ago. First I talk about the programmable nature of the lights, then I talk about the built in animations. For the code I demonstrate in the video, see this post." - Link.
