ESP32-P4 booting up and running CircuitPython 🚀🐍

Core CircuitPython dev Scott has been chugging away at adding ESP32-P4 support to CircuitPython - and today tossed us a bin file that runs on the Eval board we got last week from Espressif. Native USB is still in progress, but we can connect to the REPL and save files using the USB-Serial converter. It's so fast at 400mhz, and with 16 or 32 MHz of PSRAM, it's going to be an awesome board for embedded Python! More soon!

So, the esp32c3 from seeed has these battery pads on the underside that allows you to use the integrated charge controller, which is nice for a cheap devboard.

Now, I don't have a hotplate, and the rest of it is castellated so it's easy to do by hand. My question is: Is this. Allowed.

just put some big vias through the board and flood them with solder from the underside. Is this stupid or will it work.

i dont live in canada but i feel the need to say that, no, the flipper zero alone cannot steal a car AND if you did get the necessary tools, an audrino with a cc1101 attached to it could do literally the same thing.

if the canadian govt wants to use this logic to ban a product, then literally anything used to steal a car (a hammer, a screwdriver etc) should also be banned. but i have little faith in the spineless losers that run the canadian govt since theyre using social media trends to influence thier laws.

please dont ban it in the us too please. its not fucking contraband, it a tool for learning and development just like any devboard you can get off of amazon or aliexpress.

i read this an immediately got sniped into making a demo.

I have the timers ticking down now I just need to draw them to the screen, but I forgot to eat dinner so that first.

That oled is small but it's the one I have to hand, once I have a code framework laid out I'll design a PCB or something to host buttons and then CAD a case. Not sure what kind of vibrator motors jlcpcb has in stock because if I'm careful I can build this around a nice simple devboard that has built in battery management, and then you can just order a pack of 5 boards from whoever.

I need ugly adhd tools.

I guess it’s time for my first cursed programming post.

I have too many computers at home. In between my laptops, servers, virtual machines, and devboards I have about 15.

This makes distributing tasks between them kinda hard. I can SSH or RDP into most of them but they don’t have the same software setup or filesystem. That’s my core problem.

The traditional options fit into three categories. You have workload tools like Kubernetes, job based tools like Slurm, and finally provisioning tools like Ansible (there are other options but they aren’t general purpose). Kubernetes is the popular option based on Google’s experience developing Borg and Omega. Slurm is a old classic used in high performance computing. Ansible is a tool for setting up servers (we’ll see why I included it later).

Kubernetes is designed to pack long running workloads onto a cluster of servers based on based on a simple(ish) requirements format. Most of the workloads are services like web servers and databases. It does this using containers as the basic unit.

Slurm is a bit different. Slurm solves the problem of letting a group of users run script shaped programs on a cluster of computers. Slurm is used in scientific computing to run jobs on big supercomputers.

Ansible runs short lived commands to change the configuration of computers. It’s more used to setting up software like Kubernetes or Slurm.

The first two solve the core problem of “you can’t buy a bigger computer” beyond a certain scale. Ansible solves the problem of sitting down and setting up 200 computers all the same way is a mind numbing exercise.

But all three are fundamentally about running a command on a group of systems. Each are a way of looking at a weird series of computers as if they are a single system.

But back to my initial problem. I want to run medium to long lived applications on my fleet of computers. They all have different filesystems and they run different operating systems as well.

Slurm assumes a common network filesystem so that’s not a ideal solution for me.

Kubernetes distributes containers and it doesn’t like Windows.

Ansible copies the requirements over the network (normally via SSH). It doesn’t have tools to manage longer running jobs though.

So none fit my requirements perfectly.

So that’s the basics. Let’s see what I come up with. I’d also accept suggestions if my reasoning and understanding are stupid (quite possible).

CP2105 dual UART breakout 🔌💻

Sometimes, you need more than one UART for interfacing with hardware. So instead of getting two CP2102 breakouts

you could use this CP2105

chip. We exposed the two CDC UARTs on either side plus the modem control signals so you could use this for bootloading various microcontrollers. Coming soon!

Last Monday of the Week 2023-10-02

Lots of neat new things out this week

Listening: New release from We Kill Cowboys, well, not new because they've been playing it live for a year but they mostly run in Cape Town so I didn't get to hear them even when I didn't live a continent away.

Also, finished COUNTER/weight from Friends at the Table. I think I have figured out one of the things I like about Friends at the Table, which is that they behave like a real world Darths and Droids table. They move between a lot of systems and they regularly have players playing at very different scales, often someone plays multiple characters, it's an interesting mix of very, very old fashioned TTRPG techniques with some very new styles of games.

The other way it's like Darths and Droids is that they have patently absurd names (Territory Jazz, Lazer Ted, Territory Jazz Junior!) and also have a really solid mix of detailed character driven storytelling and extremely silly comedy. Mako really bought all those robots in like episode 3 and deployed them in the final fight. Legendary.

Gonna give it a moment before I move on to Marielda but man. What a good show.

Reading: Digging through some 1999 weblog posts about contemporary server technologies in an abortive attempt at a computer history blogpost. Unfortunately turned out to not be very interesting beyond what can be easily found already.

I did finally track down where a furry writer I read pretty heavily in high school moved to when his website disappeared so that's like a ten year mystery that didn't need solving but damn if it didn't just get solved.

Watching: Movie night once again canned. Idly browsing random comedies on Mosfilm but not really grabbed by anything.

Oh. Conspiracy has a new 64k realtime demo out. I still preferred their 2021 entry but the particle effects here are very impressive, especially for a realtime.

Making: Prototype knife block prints, also picked up someone's scrapped undergrad quadcopter project cheap for parts so I am interested to dig into that.

Playing: Almost done with Breath of the Wild, beat the last Divine Beast (Medoh) and now just have to wrap up.

I was originally planning to finish "Every Main Quest" before hitting the castle but a) one of those requires basically going to the castle, b) the game suddenly spat out an "EX" quest where you do some weird fights on the plateau which I have now learned means it's a DLC thing. I will finish the first one and see how I feel but it's the first in a whole long-ass chain of themed quests that I probably don't care about.

I was also planning on doing the trial of the sword but I really do not enjoy replaying all those levels any time I die. Boring. Not doing it. I'll probably get through that soon.

In other news, new Twinbeard game: Gordy and the Monster Moon, adventure PICO-8 game from Jim Stormdancer. Cute little thing! I had a great time. Legend of Zelda-esque runaround story. You can really tell Jim has a kid these days.

Tools and Equipment: If you like me are trying to consolidate on USB-C for simplicity but you still have a pile of micro-USB devboards and also a watch charger and game controller, these tiny USB-C to Micro-B adapters are handy to just leave plugged in wherever needed.
