If you are looking for a cool looking wall hanging that could be created with a knife, or better yet a laser cutter check out this project ides. Various layers of craft board are used to create a depth design that has an interesting effect when it is lit in layers. A nice small microcontroller and some LEDs is all you need on the electronic side of things.
The prize this week is a HMC5883L Triple Axis Compass Magnetometer Sensor so you can add some directionality to your next project. This contest will run for one week (December 6 – December 11, 2015). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments. Send an email to
We have all seen these small tags on items in stores that have high cost and are easy to conceal and walk out of the store with. Since these items are left on the items sold the cost must be small and they need to be simple to de-activate by the cashier when the item have been purchased. The technology turns out be be very clever and extremely low
Love the Nordic Semiconductor tradeshow display, a big bucket of chips. Nordic is making a powerful ARM Cortex-M0 chip that can be integrated into many items. They have a cool example of doing IPv6 over BTLE. At a cost of a dollar or two I think we will see these in everything. They already sell about 500,000 of these chips per day! “Nordic Semiconductor is playing a key
If you are looking for a compact development board that has more computing power than your Arduinos this might be the time to take the plunge into the Raspberry Pi world now that the RASPBERRY PI ZERO has been released. TheRaspberryPiGuy gives us the run down. They have made it much smaller, removed all of the larger components and some have been replaced with mini counterparts. If you blow
Ian Scott Johnston has a local only burglar alarm that he would like to be able to interface with remotely. He has hacked in an arduino with a GSM module to allow him to control the system via SMS text messages. The enclosure is large enough to house all of the additional modules that he needed. The built in regulator was a linear style which was swapped out with a
KF5OBS shares a tour of the Teledyne LeCroy Factory. Unlike a high volume electronic manufacturing like TV manufacturing this facility has stations where the equipment spends significant time. They can afford to do things this way since these are not built in the millions. It is interesting to hear that these scopes need to have an antivirus scan performed before it ships. Just like high end sports cars, many of these
