#jazda — Public Fediverse posts

What's the lowest-power #RISCV #microcontroller ?

I'm planning to use the low-power core of ESP32-C6 for #jazda (no less than 7µA), but I'm sure there are cores that go lower than that.

Also, I'm running out of I/O pins on the -C6 and I might need to augment it with a "south bridge"...

#askfedi #electronics #embedded #programming

I'll be giving a talk at @rustmeet this year.
Based on the upcoming #Jazda v3.

What topic should I choose?

#rustlang #rust #embedded #programming

I hate #async in #Rust.
I say that after writing 4 toy runtimes for it.

I have a very async-shaped problem and I *still* can't use async for it without ugly hacks.

Lifetime hell is trying to kill me. Will self-referential struct save me or finish the job? Let's find out.

Yeah, I'm riding #no_std , no alloc, why do you ask?

#programming #rustlang #unsafe #jazda

@easterhegg2026 Also, I'm gonna bring the dev setup for #jazda the #openhardware and #software #bike computer. Wanna hack together with me and @karotte ?

Any #rust #embedded fans?

#opensource

Interested in #Jazda? PM me to track new progress.

Short break home and back into the maelstrom. Hello #MRMCD, hello Darmstadt :)
This time following Elvis: a little less conversation a little more hacking please.

Taking my #microcontroller and async #rust :)
#jazda

@pavel I chose Bangle.js2 as the base for #jazda because of the screen.
No idea about exact color values, but I didn't really intend to display calibrated graphics with how washed out they look.

Actually, I'm rather surprised you're investigating that. What do you want to display?

Help, I'm having trouble sifting through talk ideas for #fosdem .

Which talks would you like to hear, given the chance?

#fosdem2024 #askfedi #FOSS #SSH #SSHFS #filesystem #jazda #rust #ml

Goodbye #FrOSCon! It was a pleasure to be a helper (although I didn't submit my talks in time to be a speaker).

Next conference: #CCCamp! See you there. I'll have #Jazda.org for sale for the interested.

@fatboy Whereas the watch hardware I picked up for the #Jazda bike computer, while otherwise nice, doesn't seem have any way to turn the device completely off whatsoever D:

Verify the hardware is OK and work on board support for #jazda and #tockos #tock

@nicemicro I actually stopped any coding back in January, where other stuff took over my time (work, #Jazda). But I still have fun thinking about it.

@bbbhltz While selling #jazda.org, I learned the hard way that the price of the hardware is but a small part of what the buyer needs to pay.

#Jazda is making #upstreaming progress. It's now a supported board in #TockOS ! Very bare bones, but I'm working on adding drivers.

My last presentation about #Jazda is now available in text form.

A #downhill with #jazda.
Woop 40km/h on dirt :) The tool bag rattles like a xylophone.

The good: Jazda's unique display is amazing when the sun shines on it drectly, and still good in shade (at least to the eye).

The bad: GPS-based speed isn't so accurate under tree canopy.

Also, I need to work on microphone noises.

The feeling when you finally caught up with life and can hack on your favorite projects again.

#Tock #Jazda

This just in! I'm giving a talk about #Jazda at #FrOSCon today!

Jazda: #Rust on my bike

14:00 HS3, see you there!

#Jazda is at #FrOSCon! Check out the booth at the entrance, where my friends from #FLOSSShop sell the smart watch dev kits. Stickers also there!

Cleaning device drivers of cruft is exhausting. Yes, I did replace a rather central pice, but throughout I kept finding mistakes like using bytes instead of bits.

I hope they are gone, but am not expecting it.

Need a break before the inevitable humiliation while testing.

#jazda #Tock

My #OSHW #bikeComputer dev boards arrived!

The display and #adafruit #feather should arrive in a few days as well.

#PCB #KiCAD #bike #jazda

For those who don't follow me across conferences, I transcribed my short talk about #jazda which I gave at #gpn20 :
https://dcz_self.gitlab.io/posts/why/

@thewk Shameless plug: #Jazda has GPS and people have been comparing the hardware to PineTime.

It's however less feature-complete on the software side.

Thanks @spaetz for writing up your first experience with the #jazda devkit. I'm going to use it as onboarding in the future.

#cyclocomputer

#GPN20 is over, but #Jazda keeps rolling. How far did the conference push us? Let's look at the numbers:

- 0 bike rides with #jazda :(
- 1 dev kit sold!
- 1 lightning talk given
- 1 connection to an author of another bike computer ( https://github.com/carrotIndustries/cyclotron-mini )
- 2 wiki pages started
- 3 demos of the simulator shown
- 5 sticker exchanges filled up
- a dozen people played with the real hardware

Hello #GPN20 ! For anyone insterested in #jazda, I not only have stickers, but also took some spare development kits! Want to build a bike computer together?
