MCU Electronics projects. History This project didn’t look complicated but it was.
The MCU part is really simple: just some code for the Display, Keypad and DDS Communication. A DDS is a chip that is driven by a hi-frequency oscillator. I used a 50 Mhz clock. Inside this IC there is a big divider that goes down to less than 1Hz. GarageLab (arduino, electronics, robotics, hacking) - #42. iBionics. Insect Cyborgs NEW!

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. Math.com 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.
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.
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.

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.

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! Use three rolls of electrical tape, lockjaw pliers, one extra large adjustable wrench and a crowbar.

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. Eddiem.com 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. 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! Our homemade xylophone was a great way to put our milling machine to use cutting the bars for each note, and using the lathe for the solenoid forms and steel slugs. We made our xylophone from aluminum bars -- all 6061 aluminum alloy rectangular bars, with a 1.5" x 0.375" cross-section. We made the base from a 1/8" thick sheet of acrylic (a transparent plastic). Bunnie's blog. We’re launching a crowdfunding campaign around our Novena open hardware computing platform.
Originally, this started as a hobby project to build a computer just for me and xobs – something that we would use every day, easy to extend and to mod, our very own Swiss Army knife. I’ve posted here a couple of times about our experience building it, and it got a lot of interest. _-= Uzzors2k =-_ Project Site. Introducing...Apollo 13. Open source logic analyzer.
