3D DLP printer builds an orange TARDIS

TARDIS

This micro-sized TARDIS is the latest print from [Ron Light]'s Sedgwick 3D DLP printer. Yes, it's orange, but the print quality for such a small object is pretty astounding. The Sedgwick 3D printer is currently available as a kit on Kickstarter. For five hundred bones, the Sedgwick provides all the parts - minus a DLP projector and resin - to make your own miniature Type 40 with a … [Read more...]

Anti-Sanecraft ARTillery Cannon is farm boy engineering at its finest

ARTilleryCannon

The term "just enough knowledge to be dangerous" comes immediately to mind with this one. The official description is "a large scale pan and tilt propane Flame Effect" but that hardly does this thing justice. The Anti-Sanecraft ARTillery Cannon is a three-barrel fire cannon that can move around like its namesake and launch massive propane bursts from two 1" diameter barrels. The third barrel is … [Read more...]

Reverse engineering silicon

reverse-engineering-silicon

[John McMaster] is doing some pretty amazing work with figuring out how the circuitry in an integrated circuit works. Right now he's reverse engineering a serial EEPROM chip one section at a time. This is a 24c02 made by ST, and  he chose this particular portion of the die to examine because it looked like there were some analog components involved. He removed the top metal using hydrofluoric … [Read more...]

The cool kids all file their resistors for accuracy

file-your-resistors

Here's a tip to keep in your back pocket, you can use a metal file to adjust your resistors. [Gareth] shows off this technique in the video after the break. A metal file is literally all that you need to do some fine tuning. Just make sure you're starting off with a carbon film resistor as this will not work with the metal film variety. His example shows a 10k resistor which is reading just … [Read more...]

Facedancer board lets your Python programs pretend to be USB hardware

facedancer-prototype

This is the prototype board for [Travis Goodspeed's] new USB development tool called the Facedancer. He took on the design with USB security exploits in mind, but we think it's got a lot of potential for plain old development as well. Kudos on the [Frank Herbert] reference when naming the project. Like the characters from the Dune mythology that can perfectly mimic any person they touch, this … [Read more...]

Automatic beverage delivery system

SAMSUNG

Members of theTransistor, a Provo, Utah based Hackerspace, are showing off their entry in the Red Bull Creation contest. This is an all-in-one energy drink delivery system. It can take a warm can of Red Bull from a reserve rack and turn it into a chilled cup of goodness in no time. And it (kind of) cleans up after itself too! The process starts when a can is opened by lancing it through the … [Read more...]

F/stop printer for analog printing black and white photos

SONY DSC

This beautifully crafted device is a timer used for getting the perfect exposure when making film prints of photos. But in addition to keeping time, it also does logarithmic calculations that are based on the f-stop values used for each exposure. It does this in 1/100th of a stop increments. While he was at it, [William] also decided to pack in a bunch of other features like dry down correction, … [Read more...]
