Wow @brave Version 1.19.77 Chromium: 87.0.4280.101 (Official Build) beta (64-bit) will happily connect to pinning-test.badssl.com/ while firefox and chrome correctly handle 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 to make it wireless.

FYI @michalillich @vpecinka some fresh independent performance data about @MayaData MayaStor

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 🎂blocksandfiles.com/2020/11/30/

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....

Today @openebs Mayastor is the only CAS able to fully leverage this sort of 🤯 hardware. Learn from @richardelling - he *knows* storage hardware/software & explains the increasing localization of storage. More @MayaData news coming at richardelling.substack.com/p/t

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

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 github.com/bobek/sdg_wharton_m

Hard to tell if I recorded this 30 years or 10 minutes ago...

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

Today's 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.

Always test your parts! I have ordered 40pcs of NDP6020P from AliExpress. It's just general purpose P-channel MOSFET. I have received 30pcs from batch 9J08AR and 10pcs of 9S12AR. What a surprise - the first batch is actually N channel MOSFET! Than can easily ruin your day.

Náhrdelník pro ženu, když už máme ten det matek. Matky jsou M4, M6, M8 tak jako naše děcka :)

Tak jednoduché udělátko (aka mikrofon, jeho napájení (ještě, že jsem po dětech zdědil ten držák na baterky), osciloskop a papírová trubka) jsou připravené na hodinu fyziky s Honzou. Budeme s dětmi měřit rychlost zvuku.
