Exploring bifurcation on the PicoCalc is pure fun! 🤩🤓 #raspberrypi #ClockworkPi #PicoCalc #bifurcation #math #Feigenbaum Especially when operating the PicoCalc via USB-C cable from the Mac in iTerm2. 😎 I wrote a blog post about how to accomplish that (in German) … 👉 blog.metawops.de/gadgets/Pico...

Sooo. Ich hab jetzt mal die aktuelle Fassung meines slide decks zum Thema #AnalogComputing als Version 1.0 definiert und sage mal „fertig“. 🙈 Bin gespannt, wie die ersten Zuhörer es nächste Woche finden werden … #anabrid #TheAnalogThing #HybridComputing #Arduino #ai

Mission accomplished! ✅ After some soldering my #AnalogComputer THAT („THe Analog Thing“ by anabrid) can now easily be connected with an #Arduino to build a #HybridComputing setup. 😊

This is my late father’s #TexasInstruments #calculator SR-56. It still works fine, no LED display problems. 😊 I replaced the old 600 mAh NiCd batteries with a 1150 mAh LiPo battery and a TC4056 USB-C charging board. Plus a 3D printed battery cover. Now everything fits & works fine. #sr56 #3dprinting

Fascinating! The two adjacent #Ulanzi displays show different illuminance values. This explains why – when in auto-brightness mode – they show different brightnesses. ⇒ Will setup a #HomeAssistant automation that sets both brightnesses using one of these sensors! 😏 #Awtrix #SmartHome #HomeAutomation

Loving the new Custom Widgets we get with the latest beta of the #iOS #HomeAssistant Companion app! Great to be able to freely edit the text as well as choose color and icon. 👍👍 #SmartHome

The marked point is the moment where I shutdown my Windows 11 VM that was running on my #ProxMox server. Interesting how much power it draws – app. >25 Watts! ⚡️ #SmartHome #HomeAssistant #Windows11 #VirtualMachine

I no longer automate the evening lights depending on the sunset time. Bad weather ⇒ earlier dark. So I use the light intensity sensor from my weather station and switch on the lights if the value falls below 50 lux. 👌 Here's today's light intensity curve … #HomeAssistant #HomeAutomation #SmartHome

WTF?!? What is #Elgato’s Control Center App doing there?! Every 2 seconds an ICMP (ping) packet with the lyrics of the song “99 bottles of beer on the wall” in the data frame – and counting backwards (like in the song) to 0 where it starts all over again?! 😂 Hilarious! #Wireshark #networksniffing

I‘m pretty used to Casios having a ∛ key. But look at the Casio fx-300ES PLUS 2nd edition! It has a dedicated 1st function (!) x³ key! Crazy! #casio #calculator #calculators #pocketcalculator #pocketcalculators

Hehe … Ich habe seit kurzem einen #BambuLab #A1mini mit dem AMS lite und auch erste Erfahrungen gesammelt. Das ist schon schön, aber zeig mal Deinen Filament-Müllberg! 😞 Bin aber DERART begeistert, dass ich jetzt auf den X1C upgrade! #3DPrinting

Don’t even have a hardware where I could put a firmware on! 😂 This is my Bus Pirate … 😊 Do have an Open Bench Logic Sniffer v1.04, too. 😊
