Our first open source Homeland Security non-lethal weapon project – The “Do-it-yourself Handheld LED-Based Incapacitator: THE BEDAZZLER”. After attending a conference where the $1million “sea-sick flashlight” (THE DAZZLER) was demoed by Homeland Security, we decided to create an under $250 version and here are the source code, schematics and PCB files! This is not a kit – but it is an Arduino project! – the M4V is here for the podcast folks…
Update: We’ve included a transcript of the video for the hearing impaired and well, we think all videos should have transcripts. For transcripts we used 3Play Media. We uploaded the video, they transcribed it, we paid via paypal, all under a week and under $30 for two videos total.
Rocketboom Tech correspondent Ellie Rountree visits engineer and founder of Adafruit Industries, Limor Fried (Ladyada) to talk about our DIY open source electronic kits! (MOV).
Woo! Arduino Budget Pack – the under $50 Arduino pack! – An optimized collection of parts and pieces to experiment with an Arduino at home, school or work. Great for students and those that want to get their feet wet, no soldering required!
This pack has only the basics to get you started. That allows us to keep the price low while giving you the choice of what shields, sensors and accessories to add in.
Once you have the pack, check out our free online Arduino tutorials…they’re designed for everyone, even non-programmers!
Includes:
Arduino Duemilanove w/Atmega328 – The latest and greatest Arduino revision, assembled and ready to go, including 4 rubber feet to protect the board from the worktable
3′ USB cable – Perfect for connecting your Arduino to a computer
Here’s a video (m4v) about our new business cards, we’ll have these at Maker Faire this year! They’re laser cut “SPIROGRAPH” (hypotrochoid) cards, pop out the gears and you make your own designs!
int photosensorPin = 0;
int piezoPin = 9;
int val = 0;
void setup() {
pinMode(piezoPin, OUTPUT);
}
void loop() {
digitalWrite(piezoPin, LOW);
val = analogRead(photosensorPin);
val = val/2;
for( int i=0; i<500; i++ ) { // play it for 50 cycles
digitalWrite(piezoPin, HIGH);
delayMicroseconds(val);
digitalWrite(piezoPin, LOW);
delayMicroseconds(val);
}
}
In this video (m4v) we show you how to take a $10 pager and make “pager scanner” – it can see all the pages and pager data on the pager networks – surprisingly it’s still used for a lot of interesting things and for transmitting data to many devices. Breadboarding diagram for 2-fsk decoding here & download PDW here.
It’s Friday night at Adafruit, usually that means we take apart something… Here’s part I of reverse engineering a pager (m4v).
NOTE: Oops, I was tired. There’s a mistake in the video! The chip is a TA31149 4-FSK (not 31142 2-FSK), and I printed out the wrong datasheet. Still, its pretty much the same idea/chip, just follow the ’31149 datasheet for the correct pinouts, there are -two- serial lines for 2 bits of serial data. Sorry about that!
Overview video on using 2 Xbee modules, Adafruit adapter kits and FTDI cable to transmit MIDI wirelessly. If you have a modern musical instrument, theres a good chance it has a MIDI port. MIDI is an ancient serial protocol that runs at 31.25Kbs, often they come in pairs an Input and Output. Setting up MIDI gear usually requires lots of cabling, tying inputs to outputs across a studio or stage. In this XBee tutorial we’ll show how to configure the XBee to talk at the MIDI baud rate, and then how to create a bi-directional wireless MIDI link… (m4v).
Not too long ago there was an xkcd comic featuring the Kindle, we knew someone would eventually laser etch a new Kindle 2 but we didn’t expect it to be us! Here’s the first ever laser etched Kindle 2! Sean brought his over to the shop today and we “experimented”. We used 80% power and 100% speed on our Epliog 35W laser, the laser burned off a thin layer of metal and the results look great.
