OLDA is a tool enabling "real-time debugging" (The project image shows a prototype used in a project to assess software execution timing.)

A smartwatch, but without the complications of a smartwatch.

This board combines the force of the Raspberry Pi with the mechanical force of powerful LEGO Mindstorms motors. Four LEGO EV3 servo motors can be connected, with PWM speed control for two of them and direction control for all four. LEGO EV3 motors have built-in optical encoders that generate pulses when a motor rotates.

The 6-digit VFD clock is built around 6 Russian IV-22 VFD tubes and looks very familiar to the popular 6-digit Nixie Clock.

I am working on a complete high performance transceiver for narrow band SSB/CW (and possibly also AM and FM) on shortwave and/or VHF (amateur radio bands) based on signal processing in an FPGA together with 24 bit ADC and a very fast DAC.It is stand-alone and not like most other SDR projects that are relying on a PC.

This shield is based on the extremely popular SDR-project published in the May 2007 issue of Elektor Electronics. The original author Burkhard Kainka also made this new design, now as a shield for an Arduino Uno (-based) microcontroller board. The antenna preselector section was omitted and the CY27EE16 programmable oscillator replaced by a SI5351 from Silicon Labs.

Reads two PS2-keyboard and transmits MIDI commands. Includes arpeggiator and learn/replay mode.

What is it: An RF Power Meter is a device which you can use to measure the power a transmitter outputs. Why did I built it? Read all about it!

The 2018 Elektor Labs Summer Contest is about PCB order pooling. Tell us who your favourite pooling service provider is and why and maybe win a gift certificate.

Stromklemme die ohne abisolieren, Stromkabel in unterschiedlichen Stärken verbinden kann !

Pollux is a universal intercom system, to be used to interconnect radios, telephone, intercom, audio systems based on Raspberry PI

This project is the result of the LPRS contest run last year. The winner's project is to be finalized by and published in Elektor. So here we go.

Did you ever wonder how fast your hamster can run? With this project, you may find out!

iTimer is a versatile and elegant solution for countless applications that require timing

The AVR Playground is a hybrid of an Arduino Uno and a traditional microcontroller development board.

This project describes the generation of sine waves by a simple recursive digital filter in a way that only 8 bit shift/add/subtraction operations, two permanently occupied 8 bit registers and no data tables are required, therefore permitting the usage of low-cost micro-controllers without multiplication units and little storage capacity.
