How much data has your router passed? No idea right, well check out this LCD Router Traffic Counter project if you are curious how many bits have passed through the mystery box. “Using my python library as a reference for how to use the display, and my XML parsing script for ash, I was able to cobble together a working project quickly.”
This Geiger Counter USB Hack takes an inexpensive Geiger Counter and makes it able to output counts our via USB. This would be very helpful when you want to take readings logged over time. It uses a small microcontroller to interface to the computer. Check out the small circuit implementation above! “The Kvarts DRSB-01 (Кварц ДРСБ-01) is a simple consumer Geiger counter. It does not feature a display of any
Touch sensors are getting more and more popular these days especially since many low cost microcontroller have them built in. If you have a controller that doesn’t have built in touch sensors there are many chips that do just that. The Freescale MPR121 is one of these chips. This MPR121 Touch Sensor Controller Project will give you the pointers you need to get your feet wet with touch sensors. “This
This Audio Spectrum Analyzer Kit looks like too much fun. I remember back in the 90s I had a huge spectrum analyzer with lots of knobs, buttons, levers and dancing LEDs. With the lights down the display was as mesmerizing as a lava lamp. But just like my lava lamp the EQ was phased out. There is lots of technology packed into this kit but unless you can solder surface
I remember some of the showers at campsites have timers on them, you crank the 5 minute dial to get a quick shower. When you are timed like this you are very conscious of how much longer you have before the water automatically shuts off. I was thinking that I could save tons of hot water fees if I implemented this in my own house although I never did since
Rolling your own PCBs is something that is great to speed up the development time when designing a new circuit. Even now that there are quick and fairly cheap board houses that can make production quality boards it still takes days instead of the hours it would take if you made your own in your home lab. Keith Neufeld has perfected the isolation method of PCB creation on his MakerBot.
If you need a stable time base for something such as a clock project have a look at this DIY 1Hz Time Base project from The Hackers Bench. I see that the board that was used is one from our friends at Gadget Gangster. “In principal this circuit is extreemly simple. You build a crystal oscillator, and then you divide it’s output down to 1Hz. The crystal we’re going to
