I appreciate that they made this ESP32-C6 super small, BUT how am I supposed to work with this? Are there also tiny breadboards and tiny jumper wires that I can get?
Is there some non-prorietary #microcontroller-friendly protocol for communicating on 915 MHz US/868/MHz Europe with available hobbyist-friendly boards? Or even just hobbyist-friendly 802.11AH SOCs that aren't super expensive?
Right now it seems like one's best bet is to just go with HopeRF's #RF69HCW. It's still proprietary and has less range than LoRa, but chips and boards are a lot cheaper and far more widely available. That should be plenty for building a sensor net around one's house without needing a full WiFi and IP stack on each board or dealing with WiFi's poor penetration of walls.
A friend gave me the board of an oil heater (it has 3 relays). I wonder if I can repurpose it. I found out it has an 8-bit 20Mhz #microcontroller (PIC16F819 I/SO).
[Adreas Spiess] does his own twist on the USB Powerbank keep-alive circuit -- using a modern version #ATTiny to first characterise the switch-off delay required https://youtu.be/SgV6_Y_sg4k
He also runs afoul of chip fakers on Aliexpress #microcontroller#electronics
The talk's recording is online now. If you're even slightly interested in how to get a lossless 60fps #UVC#MJPEG video stream from a #GameBoy by watching its memory bus with a commodity #microcontroller, go check it out:
It’s alive! This microcontroller project runs on an ESP32 C3. It cycles through 7 colors and blinked the built-in LED each time the color is changed. This code does not use delays in the loop and instead sets timeouts to run the blink and change color functions.
Garbage in, garbage out still applies even to generative AI. Yesterday I decided to give ChatGPT everything as a starting point for doing work with a microcontroller and a strip of LED lights. I gave it photos of the top and bottom of the ESP32-C3 board along with a summary and list of the parameters for the board. It was able to tell me even more and then respond to prompts with a lot more detail which was very useful.
Going forward I will be putting in a lot details at the start of a new thread so that it has more context to respond. #Microcontroller#ESP32#ChatGPT
Today I finally made use of the WiFi capability on an ESP32. It was quite easy. I've shared the details on a Gist linked below. #ESP32#Microcontroller#WiFi
I started looking into using a Pro Micro with an MSGEQ7 to process audio to make LED light strips change with music. I’ll need an input source as well as capacitors and resistors which I’ve ordered via Aliexpress. It will take a long time for those to arrive, but the cost savings is considerable. An MSGEQ7 is priced at $12 on Amazon and $1.17 on Aliexpress. #Microcontroller#ProMicro
