DIY Rotational Molding

md_roto.jpg
Solsylva has an interesting DIY rotational molding, or casting, machine used for hollow casting of resin or any other material that does not require heat activation. I like their idea of using a rotisserie motor, since I think it is fairly easy to find an unused one for free. Although, a hand crank would work for quick drying resins. - Link

HOW TO - PCB pre-order check

PCB_order%20pre-check.jpg

uCHobby has an article up about checking component placement on PCBs before ordering. If you're planning on having your circuit design professionally fabricated, it's vital to do a thorough pre-check to get a better idea of the final product. There's not much worse than receiving a box full of expensive custom green coasters (unless of course you're into designing coasters) when you expected a functional board.

Building the Perfect PC--updated system configurations

buildinAPC.jpg

Building the Perfect PC authors Robert Bruce Thompson and Barbara Fritchman Thompson have updated their recommended system configurations for the new year. Pick up a copy of the book, check out their updated lists of components, and build the best PC... the one you build yourself:

  • Gaming PC Configuration - Link
  • Budget PC Configuration - Link
  • Mainstream PC Configuration - Link
  • Media Center PC Configuration - Link
  • Small Form Factor PC Configuration - Link
  • SOHO Server PC Configuration - Link

From The Maker Store:
Building the Perfect PC Cover

Building The Perfect PC 2nd Edition by Robert Bruce Thompson and Barbara Fritchman Thompson
Price: $34.99
Buy: Maker store - Link.

This popular Build-It-Yourself (BIY) PC book covers everything you want to know about building your own system: Planning and picking out the right components, step-by-step instructions for assembling your perfect PC, and an insightful discussion of why you'd want to do it in the first place. Most big brand computers from HP, Dell and others use lower-quality components so they can meet their aggressive pricing targets. But component manufacturers also make high-quality parts that you can either purchase directly, or obtain through distributors and resellers. Consumers and corporations alike are opting to build rather than buy PCs to ensure high quality and compatibility. The new edition of Building the Perfect PC shows you how to construct a variety of top-flight systems with the latest technology, including AMD Socket AM-2 and Intel Core 2 processors, that are Vista- and Linux-ready.

Homegrown jukebox

homegrown_jukebox.jpg
From the MAKE Flickr Pool:
OverWired designed and built this PC-based jukebox using arcade button switches and a KeyWiz keyboard controller.

More KeyWiz info from RetroBlast:

The KeyWiz Max 1.5, by Groovy Game Gear, is a PS/2 keyboard encoder for MAME controller applications. It's a compact 32-input encoder unit, with a "Shazaaam!" shift function to double the number of effective inputs.

AAA powered Arduino

AAA_powered_Arduino.jpg
MAKE Flickr Pool member Funax made an Arduino-compatible board powered by a single AAA battery.
A step-up converter is used to boost the battery's 1.5V output to 5V and meet Arduino's minimum power requirements. Keep in mind - this circuit would considerably reduce current supplied to the board and therefore limit its ability to power external components.

Radio control switch from junk

rcphone.jpg

This is a great way to recycle those old cordless phones into something really useful and in only 5 relatively easy steps.

Here we are going to make a simple radio controlled device using supplies from your local dumpster. This project should cost less than a dollar to make. If you spend more than a dollar on this project, you need to dig more.

Weird sound generator kits

WSG_board.jpg
Synth designer Ray Wilson is now selling kits for his "Weird Sound Generator Reborn" standalone instrument module. It's a quick build and makes for some very cool noises. There's even professional-grade front panels available for use on the enclosure.
Ray's site is a great resource for learning about synthesizers and electronics in general. His circuits are well documented with a welcome sense of humor.

Lovesick Larry

lovesick_larry.jpg

Everyone say say hi to Lovesick Larry. He's a sympathy doll made by Flickr user "brooklyn sunset":

We were inspired by Bre's Sympathy Doll project in his Weekend Projects podcast. We got out our 40 yr old Singer sewing machine and used my grandpa's old Pendleton robe for sentimental value and we now have Lovesick Larry.

Truly heartwarming - makes us appreciate red flannel a whole lot more.

Make3D --- convert your images to 3d


Stanford's 3D tool where you can upload your own 2D image and make it 3D (site seems to be getting hammered at the moment)-

Make3D converts your single picture into a 3-D model. It takes a two-dimensional image and creates a three-dimensional "fly around" model, giving the viewers access to the scene's depth and a range of points of view.

It uses powerful machine learning techniques (more details here), to learn the relation between small image patches and their depth and orientation. This allows it to model 3-d structures such as slopes of mountains or branches of trees.

Make your own plasma globe

OK, maybe rolling your own vacuum tubes was a bit difficult? Why not start out by trying to make your own plasma globe? It uses an off the shelf 250 mL flask, saving you the difficult glass blowing parts. This isn't a step by step like instructables, but it is a great starting point with a bunch of useful information. It would be a great addition to your Jacobs Ladder- Link

PID temperature controller for cooking

PID_temp_controller.jpg

From the MAKE Flickr Pool -
Member Boss Sauce shares pics of his precision temperature controller using a PID mechanism.

PID_diagram.jpg

A PID (proportional-integral-derivative) controller measures a specific variable (such as water temperature) in comparison to a predetermined setting (ideal temp). The controller then performs a corrective action via its control circuit in order to reach the desired setting (i.e. - increases power to the burner). Result = dinner cooked up just right.

The Fluidforms Cassius punching bag

139669041 F2873C42E8 O
Punch out your designs with the Fluidforms Cassius punching bag sculpture maker, Arduino based too!-

The Fluidforms Punching Bag contains a matrix of 9x7 force sensors that measure the force exerted by a blow to the punching bag. The sensors are plugged into an Arduino board that sends the values over USB to a computer using the MIDI protocol. The Computer is running a Processing sketch that receives the MIDI packets and writes the current state of the sensors to a folder in a “|” separated format. An OpenGL render then reads these text files and graphically represents the current state of the punches to the bag since the last reset.

RFL robots, BlinkMs, low power LCDs

Some new stuff from SparkFun here are a few of the items I thought were interesting...


08573-01-L
RFL Robot. This is a amazingly agile and low cost wirelessly controlled robot. The RFL robot by Active Innovations has four specially designed, independent, high-torque motors for driving, throwing, and generally being mean. We are happy to be the first online retailer to stock this exciting new product. Comes in fancy retail packaging with robot battery, charger, and 2.4GHz remote.

The idea behind RFL (Robotic Football League) is to create a league of robots and players to compete in a game of American Football. The robots can actually block, knock each other over, throw and receive a velcro football. They even talk trash to each other whenever a competitor's IR signal is detected - Link.

Blinkm-L
BlinkM. BlinkM is a “Smart LED”, a networkable and programmable full-color RGB LED for hobbyists, industrial designers, prototypers, and experimenters. It is designed to allow the easy addition of dynamic indicators, displays, and lighting to existing or new projects. If you’ve used up all your microcontroller PWM channels controlling RGB LEDs and still want more, BlinkM is for you. BlinkM uses a high quality, high power RGB LED and a small AVR microcontroller to allow a user to digitally control an RGB LED over a simple I2C interface. Multiple BlinkMs can be stranded together on an I2C bus allowing for some amazing light displays - Link.

Monolcd-L
Monochrome LCD - A wonderfully basic monochrome LCD! This extremely low power digital display is excellent for meter read-outs and counters. Each segment is driven with a AC signal. You must drive and maintain each segment with a high/low/high signal. Display works with 0-5V and 0-3.3V signals - Link.
