Wireless temperature picture frame mashup : scanlime

It’s a Kodak W820 digital picture frame, showing a graph of real-time temperature data collected from around the house: upstairs and downstairs, garage, outdoors, and even inside the refrigerator. More photos on Flickr, implementation details below… Temperature Sensors Most of my friends probably know that back in 2004, when I was still in college, I built a set of wireless temperature sensors. The PIC spends most of its time sleeping, but every 20 seconds or so it wakes up to read the current temperature from the 1-wire sensor. Every couple of minutes, each sensor transmits a burst of packets back to the base station.

As usual, microcontroller firmware for the transmitter and receiver is open source. Software The software running on the server machine has had a rough history. My reasons were mostly historical.

DIY Conductive Glue And Paper Circuit. Third Hand++: A multi-use helping hand for electronics and other delicate work. In the past I've used the third hands/helping hands available at chain electronics shops and have been frustrated with their usability.

Third Hand++: A multi-use helping hand for electronics and other delicate work.

I could never get the clips exactly where I wanted them or it took more time than it really should to get setup right. I also wanted the ability to hold small circuit boards and alligator clips just don't do a very good job. I was familiar with the adjustable coolant hose systems used to spray coolant at cutting tools in the machining industry and thought that would be a great place to start. I ordered various nozzles and hose segments from my favorite online machine tool supply company and started experimenting. This is what I came up with. These arms can be placed into pretty much any position and they will stay there.

Another nice feature is that you can make all sorts of attachments for holding whatever you need to work on. All you really need are some simple hand tools, a couple taps, a drill bit and a drill to make the basic version. Low Voltage Pro...The Best! How to Make a Vibration Detector/Meter Circuit. Whether it's truck throttling over the highway, or an airplane roaring about the sky, or whether it's a knock on the door or a purring of the cat or simply your heartbeats, the vibration level detector circuit explained here will sense them all and convert into beautiful sequencing LED light bar graph indications.

How to Make a Vibration Detector/Meter Circuit

The number of LEDs lit in the bar graph at any particular instant indicates the magnitude of the vibration force at that particular instant.Vibration is nothing but the ruffling of the air due a corresponding force generated from an external medium. For example when we speak, our vocal chords vibrate and generate the corresponding patterns of disturbance in the surrounding air. When these air vibrations enter our ear, our eardrum also vibrate at the same frequency making it audible to our respective sensory organs. Automatic Wire Cutter and Stripper by oomlout.

Wire and Cable Cut & Strip Machine - Schleuniger MegaStrip 9600. Minute Man Electronics Online Catalog. About. We are a community of makers, artists, designers, and builders focused on simplifying the world of electronics DIY by modularizing information.


Instead of showcasing users’ projects, we offer bite-size, easy-to-follow articles that help you hit the ground running. We understand that, for many, the idea is more important than the method of accomplishing it. Our hope is that by offering working code and wiring examples for almost anything you would want to make, we can create building blocks that will enable people to stop searching for help, and start getting their idea made. What’s all this talk about Modularized Information? It’s pretty simple. Imagine buying an entire car just because you needed a single part.
