(Image Credit: Northwestern University/K.Konkoly)   Researchers at Northwestern University have achieved a breakthrough: communicating with people who are in the middle of lucid dreams, a phenomenon called interactive dreaming. Participants were able to solve basic math problems, answer yes-or-no questions, and follow instructions. The team's research demonstrates a "relatively unexplored communicat ...

Keysight University Live

Posted by Fred27 Top Member Feb 16, 2021
Not sure if this is the new Scopemonth / Keysight Wave or something slightly different, but everyone like the chance to win some shiny new test equipment. There's normally lots of informative stuff too. Keysight University Live starts on 15th March.   https://kulive.keysight.com/?ref=pHwow5iyQUW2IZLU Full disclosure - using that link gives me an extra entry. Feel free to remove the ref bit if you want. ...
Introduction Concept Probe Construction Connecting It Up Testing with a Bare PCB and a Signal Generator Testing with a BeagleBone Black Wireless Summary   Introduction This blog post is a spin-off from Building Solderable In-Circuit Oscilloscope Probes After working on those probes, Jon ( jc2048 ) mentioned that in "Electromagnetic Compatibility Engineering" by Henry Ott, there was another way of using two similar resistive probes, in an arrangement that could ...
Introduction Why not just use Coax Cable How Do Probes Work? ‘Normal’ Passive Probes Resistive Probes Building It Using It Comparison with Other Probing Methods Summary   Introduction The probes attached to oscilloscopes are fundamental to getting useful captures and measurements from the ‘scope. The normally seen ‘scope probes (technically they’re called passive probes) have a special construction that is not easy to DIY; it ...
This blog post walks through one method for prototyping electrical circuits.  It revolves around using prototyping boards, copper tape, and thin insulating tapes and wires. Here's an example: The example above was built on copper-clad board, but other types of boards can be used too: The copper-clad board is great for whenever a ground plane is desired. It comes in single-sided and double-sided variants. I use double-sided which can be sometimes convenient. The tools and consumables ...

Silicon Solder Mat

Posted by Jan Cumps Feb 6, 2021
I purchased a silicon solder mat today, when I was in the electronics shop to pick up my order.     I use an antistatic mat as a generic work area, and prefer to keep that tidy. That mat can take an accidental touch of a hot iron, but it's not intended for that.   The silicon solder mat (from Velleman - Buy Belgian!) is heat resistant, up to 500° C. Flexible and can be cleaned in a kitchen sink. It returns back to its original form. Total size 45 x 30 cm. Work area with ...
