This is for the recently released ESP32-S31 which does have a MMU, unlike the ESP32-S3. The author has more details in this reddit post: https://eddrit.com/r/esp32/comments/1vait52…

I've been using eddrit.com, I think it best matches the minimalist old ui (no full size images without clicking drop-down, pagination, etc).

He was just ahead of its time in terms of grind and realism. I remember one of the first times gregtech was introduced to the mainstream was with the Mindcrack FTB modpack, most pe…

No it doesn't, the time to first fix from cold start of modern GNSS receivers is in seconds (24s on the NEO M9N). Assisted GNSS using data from the internet reduces that to under 2…

Awesome project, re fpga implementation one option you might want to explore are used Bitcoin miner control boards if you want the best logic units/$ ratio. I've used the EBAZ4205 …

To add on to this overview, there are a new class of inverters in research called grid forming inverters which don't just follow the rest of the grid. One interesting technique is …

The end of life notification for these chips were issued in May of 2022, with final orders by December 2022 [1]. The chip itself from what I can see at a glance has unremarkable sp…

Very interesting project, I'd be interested in seeing their system architecture in more depth and what tricks they used to bring the unit cost down. Another radio telescope project…

It would be good if this chip had good idle current comparable to other MCUs. I have used the ESP32S3 and it's idle current with the radio enabled, but not transmitting, is quite t…

Our university rocket team uses openrocket extensively for doing fast design iterations early in the design phase. We have also used Rasaero II which is meant to be more rigorous a…

I would suggest using a more modern IMU, the MPU6050 has been long obsoleted both in cost and capability by newer IMUs. I used the ST LSM6DSOX in my rocket flight computers, for ex…

I regularly use Mathematica for working with symbolic expressions (for its DSolve and transfer function stuff) and it is way more maintainable and elegant to have fractions, symbol…

I've found a combination of circuitjs and a spice simulator to be quick for prototyping custom analog circuits (made mainly from discretes). Circuitjs https://www.falstad.com/circu…

This is true, for example many stm32 series have a 96 bit unique id which is derived from the lot number, wafer id and position [1]. Even the low cost stm32g0b1 series I am using h…
