My Mini Servo Grippers And Robotic Arm

Posted July 29, 2015 by Chris

"A little time ago I made a robotic arm, without the gripper. So last week I draw a gripper that is compatible with a mini servo, I made two versions because I had to chose between two kinds of gears, straight and rounded. Because I first finished the straight gears version I milled this one first, but since there was a little play between the two gears I also made the second one, the one with the rounded gears."

The Magic Crystal Mood Ball

Posted July 27, 2015 by Chris

"During my search for a cool design for my lamp, I found this plastic ball that looks like one of those future tellers crystal balls, and I decided to used it in a mystical way. Since my idea became a mood ball, I thought it would be fun to have the mysterious ambient surrounding the future teller’s world, in this case, not future, but present."

Clock Calibrator/Frequency Counter

Posted July 26, 2015 by Chris

"This is a project to make something that can be used to work out calibration details for a clock/calender chip and measure frequencies with a reference having 5-10ppb frequency stability."

A PIC18F2550 Based Computer Status Monitor

Posted July 25, 2015 by Chris

"This project is a USB based computer status display. Downloads at the bottom of the page…The firmware uses microchips USB stack. The files included in the USB folder are from the ‘Microchip Libraries of Applications’ I used version v2012-08-22 of this…The support application was written in C#. Some things of note…the file HIDInterface.cs is an invisible form."

PiMony – A Smart Remote Prototype

Posted July 24, 2015 by Chris

"Presenting PiMony, a smart remote prototype built on a Raspberry Pi! As prototypes go, this is very… prototypey! It is quite large and kludgy. The goals at the moment are to learn more about the hardware side, and try out ideas for both hardware and software. Then work on the size, look and feel!"

Mac ROM-inator

Posted July 23, 2015 by Chris

"Add a bootable ROM disk to your vintage compact Macintosh! Replace the startup sound, change the Happy Mac icon, edit the ROM disk, or tweak the ROM code behavior. The Mac ROM-inator Kit replaces the stock 64K or 128K of ROM in a compact Macintosh with a full 1 MB of flash memory. Once installed, the flash ROM’s contents can be updated from within the running Macintosh, allowing for crazy customization experiments."

Christmas Tree Ornament

Posted July 22, 2015 by Chris

"This is the Christmas Tree Ornament I made. It’s a custom PCB that I designed in the shape of a Christmas Tree. The little 8 pin black chip you see on the front of the board is an Atmel ATTiny45 Microcontroller. It has 5 IO pins, and there are 20 LEDs on this board. Each LED is individually addressable through a clever trick known as Charlieplexing."

Project Sentry Gun

Posted July 21, 2015 by Chris

"On this site we have published complete directions on how to make your own sentry gun, which autonomously tracks, aims, and shoots at targets…We are a unique project in that everything we do is completely open-source. This includes 100% of our code, as well as our electrical schematics, and even the CAD design files for our Standalone Controller. Our system has been used on six continents and in more than 20 countries (so far), and is even used by the Australian Navy in their training program."

WHMS – Wearable Health Monitoring Systems

Posted July 20, 2015 by Chris

"Wearable health monitoring systems integrated into a telemedicine system are novel information technology that will be able to support early detection of abnormal conditions and prevention of its serious consequences. Many patients can benefit from continuous ambulatory monitoring as a part of a diagnostic procedure, optimal maintenance of a chronic condition or during supervised recovery from an acute event or surgical procedure."

Haptic Appointment Manager

Posted July 19, 2015 by Chris

"The Haptic Appointment Manager manages all of an individual’s appointments, ensuring they arrive on time and in the right location by subtly guiding them throughout the day. This system uses a GPS receiver and a compass to maintain awareness of its absolute and rotational position. By interfacing with a calendar of time stamped waypoints, this system effectively guides the user to his appointments by vibrating in the direction of the next waypoint."
