After seeing all the different instructables for Led cubes I was still left with a lot of unanswered questions.  So after reading everything I could find this is what I got. I decided to make the instructable after building it…so ill try to recreate the process the best I can. This cube is different from others for […]

The basis for this tube preamplifier started out as a post in the Super simple single stage tube preamp thread on the website Forum. One of the members (see Mark’s 4S Universal Valve Preamps) had suggested building a Super Simple Single Stage Preamp (“4S” Preamp for short) and there was much discussion concerning various tubes, […]

Lab Experiments involving the Heat Equation are usually one-dimensional exercises involving a copper pipe and a half-dozen thermocouples. But with DS18B20 “One-Wire” thermometer chips and an Arduino, it’s possible to measure hundreds of temperature values simultaneously. Here’s what my students Daniel Lund and Lawrence Lechuga and I came up with for 2-D temperature measurements. We […]

Tri-Axis, User Selectable ± 2g, 4g, 8g, Digital (I2C/SPI) Output, Integrated FIFO/FILO buffer, 2x2x0.6mm LGA The KX112 is a robust, low-power, I2C/SPI, 3-axis accelerometer with integrated FIFO/FILO buffer that features a wide range of embedded functionality, including tap detection, orientation, activity, and wake-up algorithms. Kionix’s XAC sensor provides outstanding stability with a market-leading combination of […]

I was wandering the internet looking for a good Arduino tutorial on how to build a binary clock with seconds, but I could not find one. So now I am  writing this for you to have a binary clock with seconds, minutes, and hours. What I did: -Because controlling 20 LEDs individually for this cube […]

I was googling around looking for some sort of device I could make using arduino and stumbled upon eshop with devices for visually impaired. What really shocked me was the price. I mean-I do realize that such sorts of devices are not really mainstream, but still, it was kinda high. So I decided to make […]

I have constructed a basic Arduino robot arm using 3 servos that cost me £15 in total plus a couple of hours in time to build and it’s very simple that I think anyone can replicate and build this. I already had the Arduino Duemilanove ATMEGA328, some foamboard, tools and glue. The robot arm has […]

I’m calling it MotionMote because it detects motion and because pretty much every type of wireless sensor or Moteino node name ends in “mote“. The possibilities for home security are endless, put this little guy in a corner near a door or on top of a cabinet somewhere and detect them intrudaz! Did I say there’s […]

Want a free board? Read below! My regular readers may already know that I never stop working on a project half-way. This is unfortunately the only exception so far, motivated by the fact that an IC isn’t doing what it’s supposed to do, that my thread on the TI support forum was left unanswered for […]

Overview This is a guide to building an Arduino-powered clock that uses LEDs to display a 24-hour clock (hours and minutes) as binary digits, an analog meter to display the seconds, a switch to toggle between time-display and time-setting mode, and 2 knobs for setting the hours and minutes. This was designed from scratch, but […]
