Blair Kelly has designed a fun looking RC car. It has an Arduino mounted in the car, there are a number of sensors that allow Blair to drive the car around viewing the drive on a computer screen. There is even force feedback so when the car goes over a large bump or bangs into something he can feel it. With a head mounted display this thing would be very immersive. The camera is mounted so that it can be moved from right to left. I can just imagine what it would feel like if this right and left camera movement was linked to head movements when wearing a head mount display! Via: Make

When someone rings your doorbell wouldn’t it be nice to know about it when you aren’t home? Well this project will do just that. Pressing the doorbell will send a message to your cell phone and send you a picture of who is there. You often hear that robbers often ring the doorbell to make sure no one is at home before breaking in. I am thinking that a few of the Arduino outputs could be purposed to spray a water gun and turn on a siren. Thanks for the tip Clement. ”How does it work ?

The ECE 4760 Final Projects are here! Check out this DIY Digital Saxophone that was designed by Brian Wang. His design uses an omni directional microphone that is mounted in a tube to reduce background noise. The player blows into the tube and the microphone pics up the wind noise to know when the player is blowing. This signal is amplified and fed into a microcontroller. Buttons are positioned on the body just like a real Saxophone has and while the player is blowing pressing different key combinations allows for different notes to be played.

Check out this great looking Binary Burst Clock that Mike Szczys from Jumptuck has built. At first glance you might be a bit confused on how to read the clock but it is actually quite simple. Mike ordered the boards from Seeed Studios and had a good experience and it was cheap! In this design a MCP7940 RTC chip is keeping track of time with the help of a coin cell mounted on the back of the board. An ATtiny84 is controlling the board, it is mounted on the back of the board also so in these pictures it isn’t visible (see the full project page to see pictures of the back) .

Just in time for Mothers Day. Dress up your box of boring chocolates with some blinking LEDs. This project by Dmitriy Abaimov uses an ATTiny13 programmed using the Arduino IDE to do the interesting blinking. The microcontroller doesn’t have very many pins but with a bit of Charlieplexing this project can control all 10 LED that were desired. ”By counting the possible spots for LED locations in the box, I decided I should use 10 LEDs. In the course of construction it turned out that a couple more could be mounted but 10 LEDs was the starting point for this project. ATTiny13 has only 5 I/Os (if we leave the 6th as RESET so we can more conveniently program it) and so Charlieplexing was used for connecting the LEDs.”

This Auto Dimming Incandescent Bulb that Dick Bipes built works in conjunction with Slow Starting CFL Bulbs. When he flips on the lights in his garage that has now been converted into a workshop he gets instant light from the incandescent light bulb while the compact florescents take their time to warm up (many minutes). As the CFL bulbs slowly increase in brightness the circuit that Dick made gradually decreases the brightness on the power hungry incandescent bulb will it eventually goes out completely. A 5 minute timer would have got the job done but it would have been a very abrupt change in lighting intensity.

This project by some 4th year engineering students will get them ready to build the next Segway. “This project consists of prototype lab module for Control Systems II. The purpose of this lab is to teach 4th year electrical engineering students how to implement control systems to a real life mechanical system. The controller seeks to balance the ball on the beam. It is also possible to set a desired position or motion for the ball.” |
