LEGO NTX projects can be lots of fun but what if you need to have one part of your project talk to another and wires are not practical? There are lots of wireless technologies around but they would be hard to interface to your LEGO NXT system. That is until now, dexter industries has developed a NXTBee sensor which allows you to extend your LEGO projects from around the corner
When Johnathan Hottell from filear.com was developing some programming for his PLC testing how things work was often not very easy. The PLC IO Simulator allows Johnathan to simply adjust value on the simulator to see what happens on the PLC logic. Turning a potentiometer is a bit simpler than draining a 100 gallon tank to see what happens in the PLC. The wiring is actually quite nice based on
I love plants but they tend to die when in my care because I forget to water them. I know that the plant needs a shot of water every now and then but I still forget, there has been some helpful electronic plant monitoring systems made, even systems that let your plants tweet to you. But this DIY Electronic Watering System from Deddies Lab is more up my alley since

We featured this Analog LED Clock last year, cosmetically it looked fine and worked great. Wellyb00t has been hard at work making a new version which you can see on his Youtube channel. Instructions and details on the clock can be found here. Via: HG Comments
We have seen DIY bullet speed measuring systems before, this DIY Paintball Gun Chronograph by Instructables user KLASH69 has been well documented and includes schematics, PCB layouts and code so you can get a jump on building your own. “The operation of this chronograph is rather simple, there are two IR transmitters and two IR Detectors, each transmitter/detector pair is placed exactly four inches apart. When an object breaks the
Make is going to have a live show twice a month (every second Wednesday). In episode 1 they are talking all about the Arduino microcontroller. In this episode they interview Steve Hoefer who made the Arduino gum ball machine that dispenses a gum ball when the secret knock is given. In the second video which I am guessing was just the second part of the live show Collin Cunningham shows
I remember spending way too much time doodling on my Etch a Sketch when I was younger. Martin Raynsford from NortHACKton wanted to bring something cool to Maker Faire UK next month and came up with this Etch a Sketch Computer, we have seen similar creations before but this one gets props for how simple it has been hacked together. “Two water bottle caps act as the knobs for the
