Graham Prophet  @ www.edn-europe.com discuss about LT3086 LDO. The 40V, 2.1A low dropout linear regulator (LDO) includes current monitoring with externally settable current limit and temperature monitoring with external control of thermal limit temperature. The device includes a...

Thomas Scherer @ elektormagazine.com shares the news about a CoolMOS Mosfet from Infineon. The latest 800V CoolMOS P7 800V MOSFET from Infineon is based on their superjunction technology. The device is available in twelve classes of RDS(on) beginning with  0.28 Ω and in six...

This is a very simple mains isolated dimmer with a triac output (phase control). It uses timer0 to do the timing. There is no user interface, the value of the triac ignition delay after a zero crossing is defined by setting the reload value of timer0 (Tmr0) in the software...

Dan Meeks shares his design idea on edn.com: This Design Idea presents a low power short circuit finder that capitalizes on the ear’s sensitivity to changes in frequency. The heart of the circuit is a voltage-to-frequency converter (based on Linear Tech’s AN45, Figure 13, by Jim...

baelza.bubba @ instructables.com show us how to build a DC motor direction controller using L293D. I designed this DC Motor Direction Controller so that I could give direction control to DC motors that I am building into mini tools (drill, lathe, table saw, solder smoke extractor,...

taifur @ instructables.com show us how to convert a simple LED lamp to a smart one that can be controlled using a smartphone. A smart bulb is an internet or Bluetooth-capable LED light bulb that allows lighting to be customized, scheduled and controlled remotely. Smart bulbs are...

Light is a very popular means of communication. Today, optical fiber communication is the backbone of telecommunication and internet. Light is guided through a fiber optic cable in such systems to achieve low-attenuation and high speed data transmission. Question is: Is it possible to use...

Abdulgafur tipped us with his latest project, a 5V solar powered power bank. The circuit consists of two stages, the first stage is the battery charger stage based on MCP73831 and the second stage is the step up converter based on LT1302-5 which converts the battery voltage to...
