The Tog base module contains a densely packed PCB assembly, battery, and modular expansion bus in a ultra-small plastic enclosure. The base module can operate standalone with no additional components required. The front of the Tog enclosure is transparent to allow the internal LED to be visible and allow the optical sensor to detect button […]

I came across a stash of iButton T-sense 1-wire sensors.. so I grabbed a couple and decided to check out 1-wire. Maxim makes a 1-wire device called the DS18B20. It’s a 9-12 bit temperature sensor with the possibility of being powered by parasitic power from the data line. This cuts the signal path down to a

Thank you helped me a lot just by opening that instructable !! Now enjoy my instructable. This is my first instructable. I show you updates on my cnc machine which will cost about 200 euro’s for still decent quality. Don’t hate if you don’t like this instructable, I’m just an 18 years old student from
LED Panels A few years ago I built a red-only 32 pixels high, 96 pixels wide LED Matrix, and due to all the positive responses I sought out to do it again the year after with a bigger better matrix. I did some research into affordable solutions, and as usual ended up with Chinese vendors.
Wideband communication systems usually require an ultra-low noise regulator to power the VCOs and PLLs. The regulator must also be able to reject any ripple presented at its input. In a typical system, an ac input is converted to an isolated dc supply rail, –48-V, for example. This rail is then converted to an isolated
Summary The MCP6V01 auto-zeroed op-amp features an ultra low offset voltage (VOS) and high common mode rejection ratio (CMRR), which makes it applicable to temperature measurement. The MCP6V01 thermocouple auto-zeroed reference design demonstrates how to measure electromotive force (EMF) voltage at the cold junction of the thermocouple in order to accurately measure temperature at the
Connectors have in general one interesting feature – there are many similar or almost the same connectors on the market. Audio connectors are not exception in this. Even though they look the same, many times there are huge differences in price and mainly in quality. If we supposed, that every producer designs and makes his
Uncompromising quality audio connectors for a compromising price Continue Reading
A term „EC fan“ (electronic commutation) is generally used to mark energy-saving AC fans. In fact, these are DC (brushless) fans with AC/DC module and other electronics. EC fans reach up to 90% efficiency and they consume 50% less energy than traditional AC fans. At the same time, a typical „50Hz“ motor noise is eliminated
Modern EC fans are able to save up to 50% of energy Continue Reading
What began as research to improve telephone service became one of the most important inventions in electronics history. In 1945, AT&T’s research division, Bell Labs, began working on technology to replace vacuum tubes and make long-distance telephone service more reliable. William Shockley organized a solid-state physics group to research semiconductor replacements for vacuum tubes and

I’ve just finished a little Arduino project. It’s a shield for the Arduino Uno that lets you measure inductance. This is a functionality that I found missing in just about any digital multi meter. Yes, there are specialized LCR meters that let you measure inductance but they typically won’t measure voltages or currents. So I
