New ElektorLabs Magazine Edition 5/2019 Available

LimeSDR Mini -- Functions Maxi! A pocket-sized SDR for transmitting and receiving

Although Elektor Magazine and their Labs have been relatively slow to jump the bandwagon called retro & vintage electronics, and specifically the revival of the Nixie tube, the projects and background articles we did see were delightful and well-engineered. The prime examples are the New Precise Nixie Clock and the Q and A on Nixie Tubes. In the wake of their Nixie and VFD clock projects, free-lance contributing designers Ilse Joostens and Peter S’heeren from Belgium (just around the corner from Elektor Labs) now surprise with another gem for in the living room: a thermometer with a traditional degrees C/F column but a “warm” readout. The secret: a perfect match of the old and the new.

The MightyOhm Geiger Counter is a device for detecting beta and gamma radiation levels. Because radiation is so harmful, you may want to keep an eye on the environment you live in and invest in a radiation detector like the MightyOhm Geiger Counter reviewed here.

Software Defined Radio allows you to create receivers for any radio signal. You just need a single peripheral connected to your personal computer. HackRF One, is such a SDR peripheral, connected through USB. It receives or transmits signals from 1 MHz to 6 GHz. Designed to enable test and development of modern and next generation radio technologies, HackRF One is an open source hardware platform that can also be programmed for stand-alone operation.

If (like most electronics buffs) you only have two hands with ten fingers on each, but lots of measurements to make on your boards, here is an interesting gadget for you. It’s the missing link between crocodile clip and contact point. It allows you to measure, continuously, hands free, with contact points without mechanical attachment, held in place by a flexible gooseneck arm. The probes are interchangeable and the support is very stable.

Help your children dream STEAM! Neither a toy nor a gadget, this WaterColorBot is an attractive educational project, involving girls, kids, adults, and teachers into active robotics and creative making. It not only provides opportunities for young people to build and learn about computer numerical control and to learn how to program a robot. It can be used far beyond that horizon. The WaterColorBot V2.0 is essentially a specialized pen plotter, using watercolors to paintbrush onto paper before your eyes. It dips its brush in water, goes and gets the right color. Standard watercolor paints and paper are used (no specialized supplies required).

DJs and fans of light shows are devotees of USB/DMX512 converters to control their projectors from their laptop PCs. Unfortunately, those found in the commercial world are often not (well) isolated from the mains voltage. Here, on the other hand, an isolated DC/DC converter powers the isolated RS 485 transceiver. Like any DMX device worth of the name, this new converter has an XLR socket.
