#DnesBastlim 10 kanalovy merac energie (spotreby) s #esp32 #bl0910 a #esphome a teda aj #homeassisstant. Mam aj nejake navyse ak by bol zaujem.

#DnesBastlim Ako zistite vysku hladiny vo vrtanej studni? Zacnete nahravat a klepnete po studni. Prvy odraz sa strati v dozvuku ale 2. a dalsie su velmi zretelne. 85ms "RTT" by malo znamenat cca 14m k vodnej hladine. Planujem tento napad este spresnit a zautomatizovat.

New WiFi 6E and ultra-low-power Bluetooth LE microcontrollers from @EspressifSystem cnx-software.com/2026/01/07/… The ESP32-E22 is a tri-band Wi-Fi 6E and dual-mode Bluetooth 6.0 SoC, and on the other end of the spectrum, the ESP32-H21 is an ultra-low-power Bluetooth LE and 802.15.4 (Zigbee Thread) MCU for battery-powered devices like IoT nodes and wearables. Neither is available right now, but the company unveiled and showcased them at #CES2026

Chcel som vam dat tip na lacny 12V 33A zdroj co sa da "retazit" za par korun ale kym som to doluskal, stihli sa vypredat: aukro.cz/cisco-n2k-c2248tf-e… Tak aspon navod ako ich aktivovat ak narazite na nejaky dobry deal: blog.danman.eu/repurposing-c… #DnesBastlim

Hrozne sa mi paci tato krabica ale teda neviem co z toho vznikne ked to pozapajam 🤭 alebo teda ze ci sa to ma riesit metodov sluckovych prudov alebo uzlovych napati 😊

#DnesBastlim "priechodzi" RJ45 keystone. Je to vobec legalne? Nepride pre mna kablova policia?

Ako sa kontroluju ulohy ak ste (trochu) farboslepy?

#DnesBastlim supercap z Ciny. Ako mam rozumiet parametru Maximum Leakage? Zda sa mi to dost out-of-spec. Je to fake?

Pacia sa mi lacne MCU kde na blinky staci napajanie a LEDka. Ziadne xtal, 3 napajania, RC reset... #wch #ch32x035

#DnesBastlim HLK-LD2451 auto radar. Funguje cez UART aj bluetooth. Zatial mi detekuje iba priblizujuce sa auta a chce to este najst krabicku s nizkym utlmom.

#DnesBastlim USB udelatko. Prototyp fungoval tak dnes prisli PCB. Moze byt osadeny oddelovacim menicom alebo prepojkami na odpojenie VUSB a ine experimenty. Da sa osadit aj zospodu ale potom nesedia popisky.

ANALYSIS AND MYTHBUSTING – What’s cheaper to maintain? Battery, motor, or transmission replacement costs? Short and clear: incompetent journalists and mainstream media have been misleading you for years, and this should have been their job. In the Excel sheet we are making publicly available, you will find individual prices for all drivetrain components. On the far right, there are catalog numbers, "parts" images from the catalog, and other parameters. Price fluctuations for parts are possible in different countries. Corrections can be sent to us. Some prices are missing because manufacturers conceal them, so U.S. catalogs were used. TABLE LINK: docs.google.com/spreadsheets… We have put in the effort for both ourselves and you, digging deep into every corner of sustainability by researching several authorized service catalogs. After a month of searching, the data we collected is both interesting and alarming. Reflecting on the struggle we went through to gather this information—submitting aftermarket support requests, waiting for activations, paying for each access, dealing with broken links—it has become crystal clear which manufacturers will survive the rise of next-generation specialized workshops and which won't. It all boils down to three parameters: Simple, Serviceable, and Accessible! These three parameters also apply to owners of all future ICE, Hybrid, and EV vehicles because, without them, there will be NO WORKFORCE to maintain your vehicle because nobody wants to use complex system to service complex powertrains. Relying on authorized services means replacing entire drivetrain components and incurring high costs. A critical mistake by manufacturers is the use of pouch cells, which have proven unreliable and, in some cases, dangerous (EQB, Leaf, Kona). One of the parameters you should consider when buying a vehicle is "What type of cells does the vehicle have?" The priority should be cylindrical or prismatic/blade cells. For those unaware, the most critical EV component is not the battery (though it is for hybrids). The most critical components are: Electric Motors On-Board Charger (OBC) Heat Pump Battery comes in last place. Therefore, the prices of these components in this order should concern you most, along with the quality of the Right-to-Repair system. The most expensive batteries per kWh are found in hybrids, of any type. On average, the total kWh cost for hybrids is 40% higher than that of EV battery systems. The most expensive complete drivetrain systems, on average, are hybrids, followed by ICE vehicles, while EV systems are the cheapest. (This refers to the average cost!) The worst parts procurement systems, right-to-repair access, and support (backend/frontend) are from: Xpeng, MG, BYD, Stellantis, Honda, Nissan, Volvo, Rivian, Lucid, Mazda, Hyundai, Kia. MG and BYD have not yet activated their RMI systems. Lucid and Rivian have no RMI systems at all. Hyundai does not issue invoices, leaving accounting departments with nothing to process. Kia has not yet approved RMI accounts and discriminates against Croatian and Slovenian owners by blocking access to Kia Connect. Warranties you cannot rely on if you purchase vehicles from: Stellantis, Mercedes, Kia, Hyundai. KMAG shortens factory-recommended service intervals and ties the warranty to drivetrain maintenance. Another concerning factor is the price difference for parts between Germany, France, and the Balkans. All parts sold under Grand Automotive (covering MG, Renault, Dacia, Nissan) are 20–40% more expensive. It’s cheaper to buy a vehicle locally and service it in Italy or Austria. Dacia Spring is alarming, with a potentially artificial price boost on parts to push new car sales due to uneconomical repairs. Practically every damage leads to a total loss, raising concerns for insurance companies. A comprehensive insurance policy for this car should cost more than one for a Porsche Panamera. In-house component-level repair: Tesla, despite leading in statistics, unfortunately lacks an internal system for servicing battery modules or components. BMW, Hyundai, Kia, Ford, Mazda, Nissan, VAG, Volvo allow the purchase and replacement of individual components within the service network. Cheapest components: Tesla has the lowest kWh cost. VW has the cheapest OBC. Tesla has the cheapest electric motors. Tesla also has the best right-to-repair (RMI) system. Tesla and BMW offer the best powertrain value and cheapest powertrain parts. Porsche has the most expensive parts globally. Best RMI systems (critical for sustainability and cost-effectiveness): Tesla, BMW, Mercedes, VAG, Ford, Toyota. Worst systems: Stellantis, Kia, Hyundai, Xpeng, MG, BYD. The most expensive systems (unsustainable for servicing): BMW, Xpeng, BYD—this significantly increases the total cost of vehicle ownership and reduces ROI. Lucid, Rivian, and others have no support systems, meaning these vehicles should be avoided as they could become unusable and not servicable at any moment. Tesla offers the cheapest RMI system, EPC accessible even to individuals without needing a business. It’s even free, and the total cost for full access is only €612. Chinese brands have proven completely unprepared for European expansion and lack scalable systems for corporate and aftermarket needs. Some EU representatives of these brands are already considering withdrawal due to non-functional EPC catalogs and even worse support. And when all is said and done, it becomes clear why Tesla is the king of the road and the only truly sustainable and financially accessible vehicle manufacturer—unlike legacy automakers who have become mere "assemblers of outsourced parts" produced by 100 different external companies. Other statistical favorites are BMW, Mercedes, Hyundai, Polestar, Volvo, and of course, Toyota. For those considering a hybrid instead of an EV, there’s no need to look at anything other than Toyota and Lexus. Oherwise, you are looking into bankruptcy. FULL Read: evclinic.eu/2025/01/19/ultim…
