Sound travels approximately at 343 meters per second. When two speakers are placed opposite one another and they generate sound with same phases, then acoustic standing sound waves are formed.
These sound waves have enough power to keep small objects in the air.
The wave length is calculated by dividing the speed of sound by the sound frequency. Our speakers are 40Khz ultrasound transmitters and the sound wave length is 8.5 mm long.
Ultra-Sound-Levitation soldering kit contains everything needed to build such a standing sound wave generator.
On 14th October is the 20th issue of Open Fest – the biggest Open Source event in Bulgaria.
Olimex will have its traditional soldering workshop there from 10.00 to 18.00 o’clock.
Participation in both OpenFest and the soldering workshop is completely free of charge.
Everyone who wants to test his/her soldering skills is welcome. Olimex employees will help you with the soldering and guide you at the workshop.
For these who can’t participate in the workshop, the Ultra-Sound-Levitation soldering kit is available on Olimex web site for sale and can build one at home.

The biggest Free Libre Open Source Software and Open Source Hardware event in Europe – FOSDEM 2022 will be again online on February 5th and 6th. Check the devrooms and mark the talks you want to attend.
My talk will be in Computer Aided Modeling and Design devroom and I will speak about how we push the limits of KiCAD with our most complex OSHW board the iMX8QuadMax.
https://fosdem.org/2022/schedule/track/computer_aided_modeling_and_design/
There will be chat channel and I will be available to answer your questions.

Silicon Labs stopped selling Si3204 POE controllers which were inside our very popular ESP32-POE and ESP32-POE-ISO boards. There is no stock anywhere neither information when they will be back in stock. So back in August we start searching for alternative and we evaluated several other solutions. We liked most Texas Instruments and made some prototypes and verified that they works fine.
Then we run blank PCBs in production but unfortunately we hit two major Chinese Holidays, so instead the blank PCBs to arrive in the normal 2 weeks we had to wait 5 weeks to produce our order then another week to arrive here.
Meantime we sold out all our stock of ESP32-POE and POE-ISO and created solid backlog before we stop the sales on the web.
We are glad that this week we shipped all backlog orders and now the boards are again for sale!
The new revisions of the boards are REV.G and the PCB info will be updated on GitHub tomorrow. From user point of view nothing changes – the new revision operates exactly the same and have same functionality as the previous Silicon Labs based solution.

STMP157-OLinuXino-LIME2 Open Source Hardware Linux computer running Mainline Linux is in mass production in four variants:
User Manual for the boards is available on the product web page.
Debian and Ubuntu Linux images are pre-build and ready to install and run.
The images are build with Olimex script Olimage which is available on GitHub.
Olimage user manual explains what is included in it and how you can modify uboot and kernel to include drivers for devices which are not included in Olimex official images.
