Electronic Circuits on Circuit Exchange International (CXI) RF Remote Control --- How to build a simple remote control system --- Note: Ming no longer manufactures the RE-99 receiver & TX-99 transmitter RF components. We will leave this project up for users that may still have the Ming RF components. If you plan to build this project, simply replace the RE-99 receiver & TX-99 transmitter with the RWS-434 & TWS-434A RF receiver & transmitter modules found HERE . Due to the huge interest in this project, I have just recently finished the NEW schematics. This project uses the Ming TX-99 V3.0 300 MHz AM, RF Transmitter module shown below for transmitting data. The photo above shows the Ming TX-99 V3.0 . Here's a quick sample of how to configure a switch to power up the transmitter and enable the transmission: Transmit Switch Configuration Using the pushbutton switch to make/break the ground connection for the power circuit to your transmitter, you save power and only transmit data when you push the switch. Note: Ming now has a new version of the RE-99. Click HERE For
SchematicsForFree.com VPT 7 VPT 8 by HC Gilje, released may 2018. Video Projection Tool (VPT) is a free multipurpose realtime projection software tool for Mac and Windows. VPT 7 was downloaded over 100000 times, so in spite of a lot of other options available VPT still is popular. Among other things it can be used for projecting mapping on complex forms, adapt a projection to a particular space/surface, combine recorded and live footage, for multiscreen HD playback, for interactive installations using arduino sensors or camera tracking ++. VPT is very flexible in terms of control, with presets and a built in cue list, as well as control over almost every single parameter using OSC, midi, serial communication, built in LFOs and ArtNet. It also supports syphon (mac) and spout (windows) for sharing video streams between applications. VPT 8 is recommended for mac OS 10.12 or later and Windows 7 and 10 (although VPT 7 works great on Windows 7).and yes, it is still FREE! VPT 8 has a lot of under-the-hood changes. Download

How to Automate Your House With Your iPhone The iPhone’s ability to connect to wireless systems via Wifi and/or Bluetooth opens up a wide range of potential devices that the iPhone can control. This functionality isn’t limited to your television or stereo but expands over a variety of electronic equipment in your home. Today we’ll take a brief look at ten iPhone applications that are built to control elements of a home automation system. Examples include everything from video cameras and security systems to lighting rigs and automatic blinds. What will you control? Read Before You Buy The big disclaimer that you should be aware of before buying any of these apps is that almost all of them require extra hardware of some sort. Needless to say, many of these apps are targeted at serious technology geeks already familiar with home automation technology. HomeWorks Light Control Required Hardware: A Lutron HomeWorks System (more info…) CozyHome “With CozyHome you will be able to control and monitor your home automation systems. House Control
Homo ludens electronicus My interest in electronics started when I was 12 years old, although I had built electric devices (lighting systems, flashlights, solenoids, even a motor) much earlier. At age 12 I started the real thing: Radios, sound effect generators, light games, etc. This obsession of building things led to a career in electronics, but also it has become my most interesting hobby. I regularly design and build things, and now I will share my better documented projects with you. Each of the following links leads to a page giving constructional information (schematics, sometimes printed circuit layouts, and text) for an electronic project. Power supply and switching technology 13.8 Volt, 20 Ampere linear power supply: A semi-traditional power supply for communication equipment, using negative-rail regulation with grounded pass transistors in a configuration that gives some unique advantages. 160 Volt, 3 Ampere DC motor power supply: A very compact, efficient and simple off-line buck regulator.

LIME ART GROUP – Interactive Video Mapping 101 - 200 Transistor Circuits e-book. It contains a further 100 circuits, with many of them containing one or more Integrated Circuits (ICs). It's amazing what you can do with transistors but when Integrated Circuits came along, the whole field of electronics exploded. IC's can handle both analogue as well as digital signals but before their arrival, nearly all circuits were analogue or very simple "digital" switching circuits. Let's explain what we mean. The word analogue is a waveform or signal that is changing (increasing and decreasing) at a constant or non constant rate. But let's crawl before we walk and come to understand how to interface some of these chips to external components. Colin Mitchell TALKING ELECTRONICS. To save space we have not provided lengthy explanations of how the circuits work. KIT OF PARTS Talking Electronics supplies a kit of parts that can be used to build the majority of the circuits in this book. MORE INTRO There are two ways to learn electronics.
