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.
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
ETH Zurich is developing a new radiation-robust microcontroller that uses the triple lock-step method to validate its own computational results. The basis for this is a RISC-V based design.
Lockstep is nothing completely new in the RISC-V area either, but the focus on energy consumption is interesting. Perfect for satellites!
Andreas Spiess reruns a video from 5 years ago in which he destroys or damages several components in an attempt to build some random project he found on Instructables and then connect it to electronics it was never originally designed to be connected to. It is a favourite video that I refer people to whenever they try using a microcontroller, Raspberry Pi, etc to switch inductive loads https://youtu.be/ReFUr3KuK40
#RetroBSD is a port of 2.11 #BSD#Unix intended for embedded systems with fixed memory mapping. The current target is #Microchip#PIC32#microcontroller with 128 kbytes of RAM and 512 kbytes of Flash. PIC32 processor has #MIPS M4K architecture, executable data memory and flexible RAM partitioning between user and kernel modes.
It works y’all! A #circuitpython powered typewriter machine. The #adafruit KB2040 blips out a sequence of binary data into a Swintec 1146 CMP’s parallel port, one character at a time. When the typewriter receives a newline, it tells the code it’s busy, and taps out its text buffer.
Just had a look at the release video. I was looking on things to criticize it on, but couldn't find anything. ESP32 integrated...a bunch of memory (which I probably would never use though tbh)... and is that an LED matrix I see? Also USB-C!
The price point is surprising - $20. Even converting that to AU, that's an amazing price. I think I saw R3s on sale for 3 times that at core electronics...but then again, core electronics will be core electronics.
I am struggling with the cargo paths, which i think i corrected by hand - not very nix like. But i fail to get the toolchain for esp running.
Cargo-espflash seems to kind of work but cargo-espup is not a thing.
