There are lots of items out there that promote proper tooth brushing, you can get toothbrushes that play a tune for a few minutes, you can get toothbrush timers but there is nothing that can tell you how long you need to spend on each section of your teeth. That is where the Arduino based Toothbrushing aid called the Brushduino comes in. It knows when you are brushing by the
If you are a light sleeper and don’t need much to wake you up in the morning then this DIY Gentle Wake Up Alarm Clock by Michiel Spithoven might be the ticket for you. On the other hand if you can sleep through a thunderstorm then you may want to look into a real loud alarm clock instead. 🙂 “First I wrote some test code to check of a small
Our friend Bob Davis is working on an experimental device he calls an Ionic Spinner. It’s working but still needs some fine tuning. The first video he describes the creation but the demo doesn’t work too well, in the second video you can see the modified design and the spinner spinning away. Bob is using a TV flyback transformer in this experiment so use extreme caution if you attempt to
Thanks to Stanley for sponsoring the contest this week. They will be providing a Compact HID Spotlight to a lucky contest winner. This flashlight would have come in handy last year when we did some travels and visited a number of campgrounds. It usually ended up being dark when we were setting up camp and light was always an issue. We had a number of flashlights but you can never
We have seen tons of cool rubber band guns and lots of potato guns but I think this is the first Sausage Gun I have ever seen. The resulting gun after a 4 hour build looks like lots of fun. I guess it would be classified as a less lethal weapon since I think it would hurt but I don’t think it could kill.
Our friend Daniel Eindhoven from the Netherlands has got his hands on an interesting piece of ancient medical equipment. He will be refurbishing this Voodoo Magic High Frequency Healing Device from the 1930s. I wonder if Dr. Eindhoven does house calls. 🙂 It is truly quite shocking what people used to do to cure you. I guess some of its applications are not far fetched even these days though. “This
Here is an interesting Linear Clock that is driven by two Stepper Motors. It is using an Arduino Mega as the brain and an Adafruit motor shield to interface to two stepper motors. The stepper motors turn a lead screw that moves two nuts up an down to indicate the current time. Via: Adafruit
