Because this can't go viral enough, I post it also here.

The picture above shows an open source laptop by the Chinese hacker bunnie. It's based on an ARM processor, has got an integrated FPGA and some more hacker-candy features.
Here is an article about the project, here's bunnie's blog post and here is a wiki-page with more technical details.

PS: Skip to the end of the talk to see the laptop in use.

The Berkeley Tricorder is now Open Source!

multiple tricorders

[Reza Bauna] has just released the designs for his Berkeley Tricorder for the public to use. He’s been designing it since 2007 as his thesis work for his PhD, and since he’s done now (Congrats!), he decided to let it grow by making it open source!

We covered it almost 7 years ago now when it was in its first prototype form, and it has come a long way since then. The latest version features an electromyogram (EMG), an electrocardiograph (ECG), a bioimpedance spectrometer, a pulse oximeter, an accelerometer, and all the data is recorded to a micro SD card or sent via bluetooth to a tablet or smart phone for data visualization.

He’s released it in hopes that other researchers can utilize the hardware in their own research, hopefully springing up a community of people interested in non-invasive health monitoring. With any luck, the development of the Berkeley Tricorder will continue, and maybe some day, can truly live up to its name!

Unfortunately there’s no new video showing off the latest iteration, but we’ve attached the original video after the break, which gives a good narrative on the device by [Reza] himself.

A robotic tattoo artist


Here’s something we thought we’d never see: a robot that turns a computer drawing into a tattoo on the user’s arm.

The basic design of the robot is a frame that moves linearly along two axes, and rotates around a third. The tattoo design is imported into a 3D modeling program, and with the help of a few motors and microcontrollers a tattoo can be robotically inked on an arm.

Since the arm isn’t a regular surface, [Luke] needed a way to calibrate his forearm-drawing robot to the weird curves and bends of his ar.  The solution to this problem is a simple calibration process where the mechanism scans along the length of [Luke]‘s arm, while the ‘depth’ servo is manually adjusted. This data is imported into Rhino 3D and the robot takes the curve of the arm into account when inking the new tat.

Right now [Luke] is only inking his skin with a marker, but as far as automated tattoo machines go, it’s the best – and only – one we’ve ever seen.

Building a wooden air raid siren


A while back, [Matthias] was working on a dust collector for his shop. Being the master woodsmith he is, he decided to build a dust collection system out of wood. Everything worked out in the end, but in creating wooden impellers and blowers, he discovered his creations made a lot of noise. For this project, instead of trying to quiet his blower, he decided to make one as loud as possible in the form of an air raid siren.

The basic idea behind [Matthias]‘ air raid siren is to make two impellers that force air through two stators along the perimeter of the rotor. As the siren spins, the air coming from the impellers is either blocked or passes through the stators, creating an alternating high and low pressure; to be more accurate, it creates a ton of noise. Stack two of these impellers together and you’ve got a two-tone air raid siren made out of wood.

For something that’s spinning very fast, we’re surprised [Matthias] didn’t have more problems with balancing his siren than he did. There are a few useful tricks to be picked up from his tutorial, though: balancing everything on a marble really seemed to help with the build.

As for how loud the siren is, [Matthias] can’t give us a decibel volume. From the video after the break, though, we can tell you it’s really, really loud.

Thanks [Dimitar] for sending this in. [Matthias], it’s alright if you send projects in yourself. You’ve earned the right to say, “I am so cool!”

Epson projector LED mod


Projector bulbs can be incredibly expensive to replace. Sometimes it’s more cost efficient to just buy a whole new projector instead of a new bulb. [Shawn] recently found a nice deal on an ‘as is’ Epson EMP-S4 on eBay and decided to take a chance. He assumed it probably worked with the exception of the missing lamp the seller mentioned. His suspicions were correct, and one custom LED mod later, his projector was up and rolling.

Without a stock lamp installed, the projector would give an error message and shut itself off. So, the first step was to wire up a little bypass. Once that was taken care of, [Shawn] installed a 30W 2000 lumen LED and custom fit an old Pentium CPU heatsink to keep the LEDs temperature down. He also wired up the heatsink fan in parallel with the stock exhaust fan for good measure.  Optical lenses help focus the light, and some custom wiring makes the LED turn on and off just like the stock lamp would.

In the end, his first experiment was a success, but [Shawn] wants to try an 8000 lumen 100W LED to make it about as bright as the stock lamp was. Check out a little video walkthrough after the break.

[Thanks Shawn]
