Binary marble adding machine
Matthias Wandel has the coolest project ever, a binary marble computer -
It had occurred to me that perhaps with an insane amount of perseverance, it might be possible to build a whole computer that runs on marbles. My second marble machine was however much less based on logic - more on just making lots of noise.Binary marble adding machine - Link.But a few months ago, I had an idea as to how the divide by two mechanisms from my first marble machine could be cascaded together to actually function as a sort of adder or counter. Once I had that idea, I knew I had to try it at some point, and recently, I finally got around to building my marble binary adding machine.
The core of the invention is a modification of the divide by two flipflop to retain the marble that falls off the right side, and retain it until the flipflop is flipped to the left by the next marble. See small diagram above right. The retention of this extra marble allows the state of the marble accumulator to be dumped. The adder would just as well add without it, but the number would have to be read off by the angle of the rockers, rather than have the device dump the count out. Really, if such an adder were integrated into a hypothetical marble computer, reading out the result as a series of marbles would be an essential element.

Parallel port oscilloscope
Here's a pretty nice parallel port oscilloscope -
This oscilloscope uses the SPP or EPP parallel port (LPT1) for reading the data from ADC. If your LPT1 is an ECP then the program automatically switches the LPT1 in byte mode (normal mode). BUT, not all parallel ports (LPT ports) are bidirectional. "Bidirectional" means, that except outputing data, the port can also read the data. How to determine if your LPT1 port is a bidirectional one? Start the LPTscope program and on the program menu select: "Bidirectional capabilities testing" then follow the given instructions.LPTScope hardware - Link & cache.

Wall wart power supplies
Randy has a good article on selecting a wall wart (power supply) for your projects, he writes -
AC adapter, wall transformer, power pack - they go by many names, but the most popular seems to be "wall wart." Although they are indeed an "unsightly protuberance," they look pretty good to me most of the time...glitchbuster.com - wall wart power supply article - Link.When I was a high school student building my first ham radio gear, a low voltage DC power supply meant buying a transformer, aluminum box, power cord, terminal strips, hardware, feet, grommets, diodes, and capacitors. Then you drilled, assembled, soldered, and hoped it didn't start a fire or shock anyone. Buying the whole thing ready to go for a few bucks suddenly doesn't seem so bad, even if they do tend to clog up a power outlet strip - or look like a wart on your wall...

Slicing STL files in POV-Ray
Evil Mad Scientist Laboratories writes -
We have been using POV-Ray to create 3D models and render bitmap slices that can be printed with the CandyFab 4000, our home-built 3D sugar fabricator. One thing that we could do to extend the usefulness of this procedure is to be able to take STL files as input, because STL is the de facto standard file format for 3D fab shops and the machines that do the fabrication. So, here's how to do it: STL files can be converted to POV-Ray format, and from there we can use our usual bag of tricks to render the set of bitmap slices.Slicing STL files in POV-Ray - Link.In this article, we explain that process in more detail: We'll take an STL file, import it into POV-Ray using the stl2pov utility, and then set it up to render a series of slices. Our example file is the sculpture Metatron by Bathsheba Grossman, who has released the STL file for it into the public domain (with some interesting results).
On a related note, happy 1st birthday Evil Mad Scientist Laboratories!

Mr. EQ - DIY equalizer
Meet Mr. EQ - a nice DIY equalizer -
While use of a graphic equalizer is often recommended for fine-tuning the tone of your instrument, no feasible DIY versions exist. However, a seven-band equalizer is not necessary to drastically shape the response of an instrument of effect. Adding peaks at certain frequencies can provide a pleasing result and is much easier for the DIY builder.Mr. EQ - Link.The Dan Armstrong Purple Peaker (and Yellow Humper, the sister version tuned for bass guitar) used two peaks for bass and treble boosts. The resulting effect is interesting, but not very flexible. We chose to apply the same concept, but with a modern approach that would provide added control to the user.

DIY Radio transmitter circuits
Chris writes in with some DIY Radio transmitter circuits...
If you can receive, what would you like to send? Here are some of the radio broadcast circuits that I like lately. Some of them I have built, others I would like to or am in the process of testing. One idea would be to set up an information kiosk, run the transmitter and player on electricity derived from renewable energy like wind or solar. You wouldn't need a huge generator to make it work, none of them seem to draw much current. It could run forever in the right setup.africatravels / RadioTransmitterCircuits - Link.

This is a condensed, single page version of a tutorial for talking pea puppets originally written by a puppeteer/puppet builder named Sean Johnson explaining how to make talking puppets from large Nerf balls. It's a cute, clever idea that's easy to make.Puppetbuilding - Talking Pea Puppet Tutorial - Link.

Palm Tungsten case mod
Chris did a simple mod so he could listen to music on a Palm Tungsten, seems weird Palm didn't do this from the start - but that's what Dremels are for...
I have a Palm Tungsten E2, which comes with RealPlayer and an earphone jack. The jack works just fine until you put the Tungsten in a Palm hard case. An unmodified case will not close with a pair of earphones plugged into the Palm because there is no hole for the plug to pass through. This situation makes it a bit difficult to put the case in your pocket when your listening to tunes or a podcast. Dremel to the rescue!The View From My Feet: Palm Tungsten Case Mod - Link.

Make your own Operation board game
Kyri writes -
I first made this game when I was around 11 or 12, when I was on some rant about how the original Operation dude didn't wear any underpants. I told my mom she shouldn't let my younger brother play the game because it was inappropriate (I didn't actually believe this, though, I just liked arguing about things back then). So...I made my own (with boxers drawn on) and called it "Disease Remover". it's a very simple game to make, and it would make a really funny gift or practice for people who want to learn more about electronics.instructables : Your own Operation Board Game - Link.

HOW TO - Make a Green Lantern ring- glowing version
Honus writes -
Here's how to make your own resin cast Green Lantern ring.This a complete overhaul of my original instructable on how to make a Green Lantern ring, which previously only showed how a cast sterling silver ring is created. Since many people don't have access to silver casting equipment I decided to show how to cast a ring in resin and also how to make a translucent resin version that glows. I'm still showing how a silver ring is made for those that are interested in the process and have access to the necessary equipment.instructables : How to make a Green Lantern ring- including a glowing version! - Link.Please note that I cannot sell these- bummer! :(
Now go make your ring and repeat after me:
"In brightest day, in blackest night, no evil shall escape my sight! Let those who worship evil's might, beware my power.. Green Lantern's light!"

HOW TO - Build a camcorder
Jonas made a DIY camcorder, he writes -
I have always wanted a camcorder for myself and not just any camcorder. I wanted one a bit like a professional broadcast camcorder, where I would be able to mount ad-ons like pre-amps, lights and all the other ever so cool stuff you'll see professionals packing. However I'm not about to pay the horiffic price of eg. a Red Camera . So let's just build one...The chaos blog 2.0 » (DIY) How to build a camcorder - [via] Link.

Milk bottle lamps
Neale writes -
I'm always interested in reusing things as often as possible. I've been reusing things to make various things around the house - shelves, hooks, etc. which I should really get around to posting up here. Ever since moving into my apartment, we've been without a light in the dining room, so I decided to set about making one from re-used parts.Whimsy Inc. » Blog Archive » Milk Bottle Lamp, Thanks Dustin! - Link.The shades are old-style glass milk bottles - I cut off the bottoms with a wet saw and sand-blasted them frosty. The wiring is from old computer power cables. The wood was all scraps salvaged from my father's wood workshop.
The design took a while to get right, but eventually fell into place. The light quality is very nice and warm.
