Yes, I know this has been done before, but I wanted to build my own, using as few parts as possible.  I built this as a table top or wall mount model, but it can be scaled up to make a coffee table.  I built it as a study for a more ambitious project, which […]

I love to integrate devices which are not supposed to be integrated and this guide shows you how you can control an Android mobile using Apple’s Remote. (Who said Apple devices work only with Apple products 😉 ) Also this is my entry to the Sparkfun microcontroller context. If you like this guide, please do […]

Please vote for this Instructable if you think it deserves it! Thanks! The Ultimate Altimeter is a super-compact, Arduino controlled altimeter capable of measuring the altitude with an accuracy of 0.3 meters, and saving the highest and lowest values it has measured. It is powered by a 40 mAh Lithium Polymer battery, uses a tiny […]

Has this ever happened to you? You wake up in the morning and realize that you’re terribly late for work/class/your weekly pedicure/whatever. You throw on a t-shirt and flip flops, sprint around your warm, heated house grabbing your belongings, and race out the door…where you suddenly find yourself surrounded by a cold, biting wind encompassing […]

Arduino text‘in. Key Features: 24 relays controlled by 4 I/O lines! Cell phone text using your Arduino. This project hacks a cell phone to text using normally open relays. After investigating cellular modules on the internet I decided it looks not only rather pricy, but also like a possibility that even after I had it […]

This drawing will display RF power and SWR readings from any SWR bridge, such as the ‘monimatch’ type. Since this type of bridge, called ‘monimatch,’ varies with frequency, the meter needs to be adjusted for each bandwidth. My main focus was on VHF/UHF/SHF, so I had planned for 6m, 4m, 2m, 70 cm, 23cm, and […]

Separating ADC uncertainty from display formatting: input scaling, analogRead limits, and verifying an OLED module’s controller before trusting its output.

I’ve just completed my second Arduino project, a sound level detector which sets off an “alarm” when there’s the sound level is to high for too long.  I built it for use in a school that wants to provide visual feedback to students when they are being too loud.  The “alarm” is a string of […]

My Lumix GH2 Micro Four Thirds camera not only shoots fantastic high definition videos, but with inexpensive adapters I can use it with older manual lenses that are cheap and often very high quality. I shoot a lot of performance videos for my daughter’s dance studio, and I use an f3.5 Nikon 28-85mm zoom lens because it provides a […]
