It seems like everything in this hectic world is going digital. This Wireless Router with Analogue Utilization Meter project takes digital information and presents it in an analog form. Video after the jump. “There are a number of ways to find out how much bandwidth is being used. This being the first pass at a digital to analogue conversion of the utilisation, I opted for simply using the uplink LED
Guido Socher build this Ethernet Weather Station project that uses an AVR microcontroller to process data from weather sensors. Software and schematics are provided. “Using an add-on card to the already existing avr ethernet board we build a weather station. That is a weather station with a build-in webserver. My original plan was to have sensors for temperature, air pressure and wind. I started a prototype and it worked very
Check out the latest Microsoft technology, it is Gesture Controlled Computer using a Webcam. “Using a $30 dollar camera and this piece of Podtech software that’s still in development, you can play with computers just like Tom Cruise did in Minority Report, by grabbing files by the nipples and dragging them around the screen. Using topological depth technology, it figures out what’s the static background, and differentiates it between
You may remember an RFID project that was featured here last year by The Digital Dawg Pound. Nick has come up with a new and improved RFID Door Entry System. Video after the jump. “I decided to try and improve the reliability and responsiveness of my previous RFID front door project (based around a client / server design), by re-implementing it using the Parallax BASIC Stamp 2e, and the 13.5MHz
There has been quite a few temperature devices featured here in the past. This temperature logger is nice since it uses one of my favorite temperature sensing chips, the DS18B20. This sensor is digital and does not need any calibration. When I make my next batch of home brew beer there will definitely be a DS18B20 floating in it. Or if I have some extra DS1822 devices from the fish
I could think of about a hundred ways to make a simpler clock, but this Ball Bearing Clock looks fantastic. Video after the jump. "I though about building a clock with a pendulum activated by the fall of bearing balls. The first thing to design was the engine which was to sustain the pendulum’s oscillation: how to get enough energy from a ball to make this possible? The balls
This DIY Audio Spectrum Monitor by a Japanese engineer looks and works great, there are full construction details and code available on his site. You have to watch the video, it’s very impressive. Video after the jump. “This is an experimental work to monitor a spectrum pattern in radio band, and is a continuous project from Audio Spectrum Monitor. To analyze the spectrum of an input signal, I chose an
