I was asked by a friend a while back to create a timer to turn a pool fill value off automatically. Apparently he would turn the fill value on and walk away only to return to water overflowing everywhere. He gave me a few parameters to follow: 10 minute timeout, easy to use, status lights,

LiPo Booster is a breadboard-friendly boost converter board based on the TPS61230 IC from Texus Instrument. It has an output voltage of 5V, and is designed to be used with a single cell LiPo battery. For normal and half size breadboards, the LiPo Booster can be plugged into the power rails without blocking the vertical 5-pin
As I mentioned in my previous posting, there was an issue with my Wavetek 907 microwave frequency generator. While everything was fine during my initial testing, the frequency display is now stuck with an out-of-range display and the adjustable frequency range is limited to between around 6.9 Ghz to 7.9 Ghz (instead of all the

App note(PDF) on schottky rectifiers from Microsemi. Schottky rectifiers have been used for over 25 years in the power supply industry. The primary advantages are very low forward voltage drop and switching speed that approach zero time making them ideal for output stages. This latter feature has also stimulated their additional use in very high

Description SLOC™ (Security Link Over Coax) is a transmission protocol for simultaneously transmitting analog CVBS video and digital IP video over a single coaxial cable. The TW3811 is the receiving end of a SLOC link, converting the single SLOC signal on the coaxial cable back to separate Ethernet digital video data and analog CVBS video.

Supported components The entire component collection is open-sourced on GitHub: EDAsolver on GitHub Because this software is still in beta, the component list is very limited right now. We will eventually be adding the ability for users to add their own components if they are not already defined. Apps using EDAsolver WireWizard – an open
