A few videos ago, I showed you how to boot from USB with the Raspberry Pi 4 and said that this video would be obsolete in a few weeks. This is the case now. The procedure became fast and straightforward. This very short video shows you how to create a bootable SSD or other USB device and a short speed comparison.

In this video, I will try to find out which SD cards are best for Raspberry Pi 3. I will try to answer the following questions: 1. Does the size of the SD card has an implication on its speed? 2. Do “better” or more expensive cards from the same supplier have an advantage? 3. Is it better to buy clones or original SD cards? I assume, this info is valid also for other small Linux boards like the Orange Pi, or Nanopi Links: Results: https://docs.google.com/spreadsheets/d/12VD1l3yhHVl-CWYekX0NPqrQqzzF7qfCo6W9DWBbeUU/edit?usp=sharing SD card benchmark 1: https://www.pidramble.com/wiki/benchmarks/microsd-cards SD card benchmarks 2: https://www.jeffgeerling.com/blogs/jeff-geerling/raspberry-pi-microsd-card Discussion about lifespan of SD cards: http://tech.scargill.net/a-question-of-lifespan/ Read the CID code: cat /sys/block/mmcblk0/device/cid Benchmark script: curl https://raw.githubusercontent.com/geerlingguy/raspberry-pi-dramble/master/setup/benchmarks/microsd-benchmarks.sh | sudo bash Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa ... https://www.youtube.com/watch?v=K1EBs3L1Wpc

Let’s build a connected scale, which alarms us when the food bin is empty. Of course, we will be able to use the same principle to measure the weight of any other good like the honey in remote beehives, or even your own weight to visualize it somewhere in the cloud… So, today we will: - Measure quite small weights with an Arduino like Microcontroller - We will need some tricks to do that - Then, we will build a bowl for our cat which is capable to detect if no food is available anymore - And we will send a Twitter alarm to our Smartphone We will also slow down the clock rate of the ESP32 to fit the timing of the HX711 chip (no more needed now), and will use an OLED display and an MQTT library I am a proud Patreon of @GreatScott!, @ElectroBOOM , @Electronoobs , @EEVblog , and others.
