Our recent paper on roach-bots in IEEE EMBC and the related video PLEASE FOR A BRIEF HISTORY of OUR PUBLICATIONS Controlled by neurons, muscles are the micro-mechanical actuators of the body. Throughout history, humans have indirectly benefited from the muscle power of animals around them to build various civilizations.

To achieve this goal, we presented a novel surgical procedure at Cornell University to insert artificial implants into insects at early stages of metamorphosis (Figure 1).

TI-Nspire Programming - TI-Basic Developer

The calculator's programming system is remarkably similar to that of the 68k's hardware, but because the Nspire's internal core is different, it needs a section on its own. Unlike all the older TI versions, the Nspire does not have a home screen or a graph screen. Instead, the calculator runs on a document that has five applications: Calculator, Graph and Geometry, Spreadsheet, Notes, and Statistics. The programming operates under the Calculator application. Although the Nspire makes good use of form and screen resolution, the programming is very limited compared to older versions. Activities for TI Graphing Calculators.

I recently had to get rid of my rarely-used oscilloscope due to space restrictions and started looking at alternatives. The handheld devices started from about $70, but had known of some PC kits. I thought, couldn’t I just use the input for my PC sound card? So came across the Poor Man’s Oscilloscope. I also knew of $300 iPad oscilloscope, which was crazy money.

Sat lonely in my box of old electronics, however, was a upgrade-made-redundant Android device. How to Build. Lab3 - Laboratory for Experimental Computer Science. Here we show a little Theremin module which plugs onto a Arduino Board that gives out the tune to a speaker or puts out the tune as control signal like MIDI, Servo etc.

Lab3 - Laboratory for Experimental Computer Science

We were using this device not only as a musical instrument, various kinds of proximity sensors, pointing devices or as interface in combination with Processing, Max or Pd have been build with this technique. How it Works The Theremin Module itself is as little LC type Radio frequency oscillator which generates a radio wave and gives out the frequency signal to the Arduino board. An Antenna connected to the LC resonator provides the Theremin effect when a person or some conductive material is placed next to the antenna. This leads to a slight frequency deviation of the oscillator frequency which is registered by the Arduino software. Vulpestruments. Flux, flux, flux. InMoov. Hacked Gadgets – DIY Tech Blog.

Hack a Day. The Mechanical Vivarium of Dr. Iguana. 5V Boost Switching Regulator Here's a little project I put together for a friend.

The Mechanical Vivarium of Dr. Iguana

He wanted to build a project that ran off 5V but didn't want to use a 9V battery. I found an interesting part on Digikey that can take the output of 1 or 2 AA or AAA batteries and boost it to 5V. Infact the part can be programed for any output voltage between 1.8V to 5.0V using two resistors. If you leave off the resistors you get a 3.3V output. One drawback is that at 5V output the part only puts out about 200mA with two AA or AAA batteries. 6502 Primer index. Dmitry Grinberg.

It is Thanksgiving Day, the table is set, the food is ready, and your wife breaks two cork screw pullers in the cork of the wine bottle. How do you get the cork out without digging it out and making a complete mess? Solution: Simple! Helium Frog Developments - Where crazy ideas come to life. Insentricity. MakeaFake : Nerdipedia.

MakeaFake : Nerdipedia

Some nitty gritty on creating a fake epson chip or chip eliminator. 5'th Sept 2008, It shouldn't be all that hard to make a fake Intellidge (AKA ink chip). Unless you are making ink carts this is pretty pointless. In general read only ink chips are more useful and actually a lot easier to do. I've heard from people saying they were working on a chip emulator and such but never heard the result or seen anyone publish anything. There is also scope for variations on the theme such as write-once chips or chips which are usually un-writable but can be reprogrammed if need be. The term "program" has a double meaning here. aka eddieworld. Blondihacks. Pushing Johnny’s secret buttons.


Every pinball machine from about 1980 onwards (the solid-state era) has a diagnostic control panel inside it. This is a set of buttons used to control service menus for running game tests, setting prices, gathering gameplay statistics, modifying game rules, and anything else an operator or technician might have needed to do. It has arguably become an even more important tool as these games age, because breakdowns become more frequent. Flute Finger Hole Locations. Determining approximate finger hole locations for a simple 6 hole flute is somewhat complicated.

Much of what follows is due to the analysis of A. H. Benade (see "Fundamentals of Musical Acoustics," A. H. Benade, Oxford Univ Press, or "The Physics of Musical Instruments," N. Robotic Xylophone. With the holiday season approaching, we are always looking for a way to add a little Christmas spirit to our office. This year, we thought it would be awesome to have a musical instrument that we could control with a NerdKits microcontroller kit, and have it play holiday music. Keeping true with the NerdKits spirit, we decided to build a xylophone, build the whole thing from scratch, and teach about solenoids and shift registers along the way! Bunnie's blog. We’re launching a crowdfunding campaign around our Novena open hardware computing platform.

I shook his hand at Spybar Chicago, but that was about it. His music is fantastic, the way this guy mixes music is on an entirely different level. But it helps when you have Ableton Live (DAW award winner 8 years running) and can hire a super secret team to build a custom controller for said software. Open source logic analyzer.

[studio] Created by Ubi de Feo, “from 0 to C” is a new series of workshops that aim at teaching programming using a more creative and human approach. Through the use of tangible, hand-made objects, I try to establish a clear understanding of how a computer works and what a programming language actually is: nothing but an abstraction of what we can do as humans.
