How you define wisdom? @naval Understanding the long-term consequences of your actions. -- Always keep this joke by Pavel Kantorek, it reads "When I passed here last time, funny little lion jumped at me from the bushes. So, I've kicked him..."

Dostal jsem vakcinacni certifkat ♥, ale nechapu, proc jsou v overovaci QR kodu dalsi data mimo unikatni ID certifikatu. To znamena, ze v nahodnych access logach (aspon je to https) bude moje RC, cislo OP/pasu atd. @ZdravkoOnline ?

Simple treasure chest for upcoming "exit game" for our kids. Take on classic Simon says game. #Arduino

New level of password complexity detection. If you are over (26 in my case) max suggested length you will receive a medium rating.

Printing double Klain bottle with a vintage (1987) plotterXY3141 via DIY interface for #RPi 0 (under the brown PCB). Plotter, originally connected to #ZXSpectrum is now connected to home WiFi. Dah, even the @eevblog DMM next to it has more processing power :) #plottertwitter

Wow @brave Version 1.19.77 Chromium: 87.0.4280.101 (Official Build) beta (64-bit) will happily connect to https://pinning-test.badssl.com/ while firefox and chrome correctly handle #HSTS preload and prevent connection.

Finally got time to fix Czechoslovakian 1980s desktop plotter XY4131 from Laboratorni Pristroje Praha. It moves! Currently powered by about 15y older PC with LPT. Will probably rewire with #raspberrypi to make it wireless.

Thank you @Chris_Mellor for pulling together info about @MayaData performance from @JakubPav @Volterra_ & thank you for the help Intel (@chrisjtobias & team). Ease of use of open-source Container Attached Storage plus performance. i.e. -> have 🎂, eat 🎂https://blocksandfiles.com/2020/11/30/portworx-and-mayastor-container…

Tenhle deploy se úplně nepovedl ;) @rohlikcz

I had this idea, that I will make COUPLE bridge pillars for their wooden railroad as a Christmas present. I guess I went a bit overboard....

Converting SMD module to THT (like a proper through hole...). Also catered for the needed power rating in the process. :)

Curvature of this battery pack looks a bit suspicious .... 😀

Wharton inspired Mini Clocks by SDG Electronics arrived in the mail from @JLCPCB. I just love esthetics of these clock. Just soldered ESP32 and off we go. I had to tweak the sw a bit, you can find it at https://github.com/bobek/sdg_wharton_miniclock

Nemáte někdo nějaké volné elektrony? Nám došly.

One day build -- #modbus #rs485 scanner using #esp32 and sending data over bluetooth serial to mobile phone.

Today's #dumpsterfind DC2DC converters - 12V/18A and 5V/30A. Now it's time for 48V solar installation ;)

Došly papírové krabičky, tak doufám, že příjemce ocení improvizaci.

I ran out of the paper shipping boxes. Hope that the receivers are going to appreciate the improvised ones.
