Add Lidar Vision to Your Robot
October 29, 2019 by Clemens Valens

Add Lidar Vision to Your Robot

Techniques that used to be available for multi-million defence projects only are becoming more affordable. Take lidar, short for Light Detection And Ranging, a 3D laser scanning method for mapping the environment. Initially intended for satellite tracking, today you can buy a miniature lidar for under €100. Add the software from this project and away you go (your robot, of course).

Oh, the Raw Power: Siglent SPD3000X Lab Power Supply

Oh, the Raw Power: Siglent SPD3000X Lab Power Supply

From your lab power supply, you look for power, infallible reliablility and stability of a gazlillionth of a volt. Hence the reticence towards anything in this area that is not a-na-lo-gue… Now the Siglent SPD3000X programmable power supply is, rightly, striking for its TFT liquid crystal screen. Since this one displays essential parameters and voltage waveforms in real time, does that carry enough weight to sway the opinion of old greybeards?

WaterColorBot Doubles as a STEAM Laboratory

WaterColorBot Doubles as a STEAM Laboratory

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).

Differential Probe Power Supply
May 10, 2019 by Martin Oppermann

Differential Probe Power Supply

In his article published in the July & August 2016 issue Elektor author Alfred Rosenkränzer presented a wonderfully simple differential probe for oscilloscopes, based around the AD8479 precision differential amplifier. I built one of them immediately and found it particularly suitable for measurements in the audio range, for example. But one small detail was not covered in this article: the power supply used for the probe (or for several of them). Practically all modern oscilloscopes have a USB port on the front panel for data output. Since the power consumption of a probe is very low, it makes sense to use this socket to power the probe.
