Summary The circuit in this reference design features the capability of MC34VR500V1ES to supply multiple DC voltage outputs. This device is designed to support the LS1/T1 family of communication processors, which require efficient and precise level of voltage supplies. With its four switching and five linear regulators, the MC34VR500V1ES can supply power to the whole […]

I received the Boozhound Labs JFET Moving Coil (MC) Pre-Preamp Kit a while back and I promptly assembled the small circuit board. I’m a sucker for a simple kit and a hot iron. That is where it all stopped. The circuit board remained complete and laying about for a few years. Recently I required another […]

This sensor is very sensitive and can pick up electrical signals from anything that uses power. It displays the amount of interference it picks up by sequentially lighting 4 led’s one after the other. I have tested it all around the house and its been kinda fun to see how different things compare. It can […]

Atmel has announced a new series of Atmel | SMART ARM® Cortex®-A5-based microprocessors (MPUs). Firmly targeted at IoT applications they are said to deliver the world’s lowest power consumption for all MPUs in their class. They deliver sub 200 µA in retention mode with context preserved, 30 µs ultra-fast wake-up and a new backup mode […]

Wouldn’t it be nice to have an internet-connected alarm clock that automatically sets itself, based on your calendar? You would never miss an early appointment, never forget to set your alarm, and enjoy more restful sleep knowing you’ve solved the nightmare of regulating your alarms. An internet-savvy alarm clock could even watch your inbox and wake […]

This reference design is a simple VGA signal generation that uses the Freescale’s MC9S08SH16VTJR, which is an 8-bit microcontroller that has Central Processor Unit (CPU) speed of 40MHz with a maximum bus frequency of 20MHz. It has an internal clock source module containing a Frequency-Locked Loop (FLL) controlled by internal or external reference. Its precision […]

If you’re a PCB electronics designer, you know how important it is to review your designs thoroughly before sending them to manufacturing. It’s costly – and embarrassing – to find design errors in a production board. You also know how difficult it is to really check everything in CAD. You’re dealing with multiple layers, so […]

A device operates OK until it reaches stable operating temperature … a typical situation in praxis usually caused by a faulty component or faulty (cold) joint. Localization of such a fault is easy only if we can cool down (locally) a given component or a given joint. It´s often possible to suppose a source of […]

The Idea So for some reason I bought 2 IKEA lamps at a flea market. As IKEA furniture has a long history of being hacker-friendly, I figured they shouldn’t be an exception to the rule. My plan? Fit a few 10W RGB LEDs in there together with an ESP8266 to use the final result as […]

The Idea Update: Looks like somebody had this idea before me and made a product out of it. Just Google Fake TV. In fact, you can also buy a clone of this from AliExpress – again, just search for ‘fake tv’ in AliExpress. The Chinese versions can be had for about $12 in your hand […]
