The first question I often get about this creation is “Why?.” The answer is quite simple, I am an engineering student at Stony Brook University. We play a game on campus called “Humans vs. Zombies.” That fact coupled with my over competitiveness, and my drive to engineer things most people wouldn’t is what ultimately spawned […]

Week 01 January 11, 2012 (1 hour): Met with professor Talavage to discuss the basic functionality of the headset sensor devices that will be used to collect data for this project. Discussed challenges of interfacing these devices to the base station using the USB protocol standard. January 11, 2012 (1 hour): Met as a team

Ok, so there are heaps of immobilisers out there but with most of them, if someone has your keys, they have you car. What good is a car alarm with 3+ point immobilisation if someone manages to get the keys and of course the alarm remote. This is a simple immobiliser based on a PIC12F629 and

In this tutorial I show you step-by-step how I install a PIC microcontroller inside of an Xbox controller in order to provide custom functions. Now that you have the methods, all you have to do is go write some code and program a chip! Well, I know this is easier said than done, but check

By embedding a PIC microcontroller into an NES controller, it can be converted into a replacement for Apple’s iPod remote. (Only 3rd and 4th Generation iPods have this, it is a the small oval port next to the headphone jack). Update (8/26/2011): It’s been quite some time since iPods have used this iPod remote connector,

Keypads are a very commonly used input device in microcontroller-based systems. In a keypad, multiple switches are arranged in rows and columns so that they could be interfaced to a microcontroller with a minimum number of I/O pins. For example, a 12-key keypad is arranged in a 4×3 format, which allows to interface the 12

This device will trigger a camera or flash unit to automatically take a picture when an object (target) enters a specific location. It uses two, crossed infrared light beams to detect the presence of the target and close a relay that trips the camera or flash unit. Response time is about 2 ms from detection

Connected to a burglar alarm or fire alarm in the event of making phone calls playing voice messages. Controlled via DTMF actuators can operate on the spot. In recent years we have introduced several telecontrols based on the SIM900 GSM module. We released schematics and code for a gate opener (that activates when receiveing a

The Nixie Tube Ornament is a homage to the light-up&motion ornaments from the early 90’s. The ornament looks cool on a tree and makes a great gift. Finally, a use for IN-12/15 top view tubes! I used an IN-15A symbol nixie in this ornament. An IN-12 works great too. A video of the ornament alone:

“Ready for PIC“ is one of MikroElektronika‘s compact prototyping boards for 28 and 40 pin PIC microcontrollers. The board comes with PIC16F887 microcontroller which is preprogrammed with an UART bootloader firmware and thus eliminates the need of an external programmer. The on-board USB-UART module allows the serial data transfer between the PIC and a PC
