Homebrew CNC surface mount PickNPlace machine
Steve writes -
...[Here's a] video clip of my CNC Taig mill setup as a surface mount Pick and Place machine. It's slow, but it's more fun watching it do the work then it is to do it by hand! Notice how it picks up the parts in one orientation, and then rotates them to the correct destination orientation. It then "centers" the part in the "centering pit". Also notice the way-cool http://www.HighTechSystemsLLC.com Modular Work Holding System that holds the PCB down on the HighTechSystemsLLC.com tooling plate. It makes clamping the PCBs down a snap!PickNPlace - [via] Link.

Nokia 3310 LCDs re-purposed
Pyrofer is working on a great project using old Nokia LCD screens and PICs -
You can see ive managed to draw a basic map on the screen. The size of this map is limited by the ram, as the objects within have to change it cant be a rom map. There isnt enough RAM. Ive had to be very clever with ram byte handing to squeeze a large map into ram. Having static map layouts in rom isnt quite as bad.Pyrofer's Projects » 3310 Nokia LCD re-purposed - [via] Link.Anyway, im about to add movement to the player and put some basic game logic in. Then its onto maps larger than the screen that scroll. This is still the original hardware from the temp probe, no changes other than removing the temp sensor and using the single input for player control.

HOW TO - Connecting a 3.3V device to a 5V microcontroller
Spark Fun has a simple breakdown of the various ways to interface 3.3V logic devices to 5V logic devices -
If you've ever tried to hook up a 3.3V sensor to a 5V micro, you know what I'm talking about - connecting these two can be a problem! There are several ways in which a 3.3V device can be safely connected to a 5v microcontroller. This tutorial will detail a few ways in which this can be accomplished.Spark Fun Electronics - Link.Below is an example of how NOT to connect a 3.3V device (like the SCP1000-D01 pressure sensor with SPI interface) to a 5V microcontroller (like a PIC or AVR running at 5V). Although you may experience normal operating conditions, the lifespan of your 3.3V device will be dramatically shortened.

HOW TO - Make a triple barrel PIC controlled spud gun
Bill Gurstelle, this one is for you, a triple barrel PIC controlled spud gun -
This project is definitely not small potatoes -- three barrels loaded with spuds and charged with propane! Two PIC microcontrollers handle the User Interface, Azimuth and Elevation Aiming and Fire Control functions. Aiming is controlled with a joystick. The Fire Control subsystem verifies a projectile is loaded in the selected barrel before injecting the controlled charge of fuel and that the barrel is armed before firing. It doesn't verify the operator's age, sobriety or aim -- that's your responsibility. The chips will fall where they may.Gadget Freak Case #103: The French Fryin' Legion's New Secret Weapon - 6/4/2007 - Design News - Link - video & instructions.

Hacking a Digg button with a removable interface cable
Here's a neat hack for folks who have the Digg button (beginner electronics kit that mimics the Digg site, I worked on the kit)... Bobber writes -
The Digg Button from adafruit industries www.adafruit.com is a very simple DIY electronics kit suitable for beginners. It consists of a microprocessor, a 3-digit display, a button and some available i/o pins.Hacking a Digg button with a removable interface cable - Link.As it comes from adafruit, it's a counter that displays the number of times it's button has been pressed. The open i/o lines can be connected with jumpers (small pieces of wire) to produce a couple of different behaviors.
But, with a simple parallel interface connecting it to a computer, it can be a sturdy platform for experimenting with microprocessor programming.
The site, www.ladyada.net, which has all the instructions and support forums for adafruit products, has instructions for some simple software hacks based on ponyprog 2000, a program for communicating with the microprocessor. The site also describes how to make a simple parallel port connector to connect the Digg Button to your computer. The description is very straight forward, but it requires soldering the connector to the Digg Button. This is not conducive to hacking your button then displaying your warez.
SO, since I like showing off what I do, I designed a simple clip-on connector that allows me to easily connect and disconnect my Digg Button for hacking. I also created a modded version of the Button firmware, which I'm calling diggX, that can be uploaded using this cable and can itself be hacked using ponyprog 2000.

Homemade CatCamera
Another cat project today... J.Perthold made a camera that takes pictures automatically... from a cat! -
Sometimes I have some challenging ideas, or crazy like some other people would say. This time I thought about our cat who is the whole day out, returning sometimes hungry sometimes not, sometimes with traces of fights, sometimes he stay also the night out.
When he finally returns, I wonder where he was and what he did during his day. This brought me to the idea to equip the cat with a camera. The plan was to put a little camera around his neck which takes every few minutes a picture. After he is returning, the camera would show his day. First I thought about transmitting live pictures from a remote RF camera, but the equipment is too expensive and battery consumption is too high.So the idea was born and split into these parts:
- find small, lightweight, inexpensive digital camera
- develop a controller for the camera
- protect the camera from cat attack
- mount equipment to cat

Blogged - BASIC stamp based art installation gets bigger as it is blogged!
Bill writes in with a fun art installation that gets bigger the more it is blogged...-
"Blogged" is an interactive installation artwork and one day net event dealing with the concept of being 'blogged'. It attempts to pop 6 feet in diameter red balloon by using traffic from blogs linking to http://billshackelford.com/home/portfolio_blogged.Blogged | billshackelford.com - Link.It runs on Thursday May 31, 2007 live from The Ohio State University Art and Technology show "Digescape". During this one day event I will suggest a link for consideration to this installation to a number of blogs in hopes that they will blog it on their sites and include a link back to this page (http://billshackelford.com/home/portfolio_blogged). My web site will then monitor the traffic coming from these blogs and run an air compressor for 1 second for each visit, filling up and then pop the 6 feet in diameter red balloon live on the web. Visitors will be able to monitor installation with a live video feed where they can watch and listen to the air compressor fill up the balloon and then pop it if enough traffic is received.
The idea comes from a previous experience when my artwork was fortunate to be blogged by several blogs. I found it interesting to see how quickly artwork spread from blog to blog. It was also interesting to see as time passed and the posts about my artwork would fade into the blog archives, that the traffic to my site dried up almost as fast as it arrived. I think Blogged expresses the joy I felt when my artwork was blogged by other sites with the filling of the balloon with air and then the dose of reality that hits when the traffic dries up with the potential popping of the balloon.
How It Works
Blogged works by counting a visit for each unique IP address and URL referral combination to this page. For example if you followed a link from the blog Bit Babble to this page, then your visit would be counted. If you went back to Bit Babble again and clicked a link to this page, then your visit would not be counted the second time. But if you where to click on a link to this page from a different blog other than Bit Babble, then that visit would be counted too. Other blogs linking to this page are listed to the right.
The visits are logged in a MYSQL database and then used to determine how long to run the air compressor based on the total number of visits. Then the Parallax Basic Stamp with a Netburner network adapter receives the running time from the database and then switches the air compressor on using a solid state relay for the given running time filling up the balloon.

MAX - headphone amp
Jon writes -
The Millett Hybrid Maxed, or Millett MAX, or MAX for short, is a vacuum tube and solid state hybrid headphone amplifier. It is the latest refinement in a series of headphone amplifiers that began with Pete Millett, its namesake. This is a fantastic headphone amp. The design even includes vacuum tubes illumniated by blue LEDs!! Colin Toole is currently taking names and quantities for a group buy of the custom PCB designed for the MAX amp. The expected cost is $12, however, it could be less if enough people place orders. Orders can be placed until June 3rd. More than 253 have been spoken for so far.MAX Overview - Link & here's where to get the PCB.

LM555 Tick tick tick
Dave writes in -
I wanted to see how few parts I could use, from what I had on hand, to build this clicking blinking LED device based on a 555 chip.uC Hobby » Blog Archive » LM555 Tick tick tick - Link.This article was submitted by Lee Bornifield as part of the "Hobby parts for articles " program. Write something of interest to electronic hobbyist and receive parts for your next project.
Probably the most expensive part is the 9V battery. There is no circuit board, and no additional wires; just bending the leads of the components provides enough connections.
The earphone clicks and the red LED blinks at a constant 137 times a minute. The exact rate depends on the value of the resistor and capacitor. That rate will be maintained very precisely for the life of the battery. It's not forever, but listening closely I could still hear the earphone faintly clicking after 6 days of continuous operation.

CMUcam3 - open source programmable embedded color vision platform
CMUcam3 is an open source programmable embedded color vision platform, you can get a CMUcam is a few places (listed on the site)... Including Seattle robotics...
The goal of the CMUcam project is to provide simple vision capabilities to small embedded systems in the form of an intelligent sensor. The CMUcam3 extends upon this idea by providing a flexible and easy to use open source development environment that complements a low cost hardware platform. The CMUcam3 is an ARM7TDMI based fully programmable embedded computer vision sensor. The main processor is the NXP LPC2106 connected to an Omnivision CMOS camera sensor module. Custom C code can be developed for the CMUcam3 using a port of the GNU toolchain along with a set of open source libraries and example programs. Executables can be flashed onto the board using the serial port with no external downloading hardware required.

Arduino variant - Bare-Bones Board
This Arduino variant (Bare-Bones Board) looks great!
Modern Device Company is a modest website to make available some of the circuit boards and electronic projects that Paul Badger has designed for use in his physical computing classes. Right now the site is focused on a variation of the Arduino, called the Bare-Bones Board. More custom sensors, and boards will be added soon.Modern Device Company - Link.Arduino is an open-source microcontroller hardware, and software, environment, closely related to the Wiring and Processing open-source initiatives. The microcontroller uses an Atmel Atmega168 chip programmed with a bootloader, so no programming hardware is required.
Arduino is programmed in the "C" programming language, with an integrated development environment (IDE) engineered for beginning programmers. The language includes support for desirable microcontroller features such as 32 bit and floating point math, many standard C libraries. Projects that outgrow the Arduino's capabilities can easily be ported to the Wiring Board, which is based on the Atmega128 chip.
