maybe using PETG with the rpi 4 would be a solution to avoid warping?

Did you end up sending this email out? I thought I submitted my email for a kit but I don’t remember if I actually managed to do so.

On that note, if you’ve got a PCB and a bag of parts, I’d be happy to do the SMD bits and let ya have one less partial kit to throw together…

Not yet (maybe tonight or tomorrow). VERY busy juggling about 4 different things and then I’m on a plane to Japan on Thursday. :exploding_head:

After mounting the capacitors and GPIO header, I test fit the Pi and there was significant interference between the Pi’s display header and the caps. I figured I had bought oversized caps so I desoldered the display header to compensate.

And that’s when I realized that I just had the Pi spun around 180 degrees. :expressionless:

No pressure, but here’s another one refreshing the inbox every day :smiley:

Really looking forward to tackling this project, thanks for making it happen!

just a quick note to say I applied the latest norns update without any ‘harm’ to fates (or sidekick/orac)

I just followed the normal norns ‘System>Update’ route, without issue.

the changes to Maiden look like a really nice step forward

I printed some knobs for my DIY Arc - the tolerances are very tight between the knob falling off and being extremely stuck to the shaft. I think I got one useful knob out of every three I printed.

Yeah. My plan is to laser cut and glue together a knob of wood. Mostly as a test(I have some Chroma knobs on the way). Will update on how it goes next week.

In case anyone is interested in running their fates with a LiPo battery, I have something that appears to be working after a bunch of trial and error.

I bought a MP2636 boost/charger board made by DFRobot for $10 CAD and 5000mAh LiPo battery (with build in protection circuitry) for $19 CAD.

Out of the box the MP2636 has problems when plugging the USB power into the board if the rpi is under moderate load — the charging circuit seems to steal too much current away from the rpi causing it to crash.

I modified the ISET resistor (pin 13) from 47.5K to 224k to limit the charging current to around 500mA, and, although that helped a bit, it wasn’t totally sufficient.

I then added a 470uF1000uF capacitor across the output rails and that seems to solve it. Now I can operate this like an UPS, switching between battery power and charging all while the rpi continues to run (even with most of the lights on my Arc lit up).

I think this battery will fit in the case, although I might have to make it ever so slightly deeper to get everything to fit.

Nice work!

For clarity - are those mods on the MP2636 or on the Pi itself?

Those are mods on the MP2636

right hand side of R15 looks like it might not be fully connected; lefthand side of R16 definitely looks like it needs resoldering, I agree with @okyeron.

Hi!
I have a fates working well after a few fails on customizing the setup.

I installed orac, vnc, the 4 encoder layouts etc.

Is there a way i can clone the sd card on the fates as a backup?

This will save me lots of time if i need to do a system reset or want to start from scratch on a new fates.

Can balena etcher clone cards? Any recommendations ?

Im on mac.

Cheers!

On the mac I use ApplePi-Baker

There’s a setting you want to use to compress unused file space - so that you can expend it back to a different size SD card if needed.

Command line nerds might ues dd

@okyeron is everything in the store truly sold out, or are sales suspended because you’re traveling? I think I might have missed the boat, even with your courtesy email (which I greatly appreciated). I’d DM you but thought others might benefit from knowing the status… thanks for your amazing work!

Really Sorry I’ve not updated everyone! :sweat:
Haven’t had enough time and I’m still packing when I should be sleeping.

The shop will show zero items available (sold out) for the next three weeks while I am traveling.

When I get back (Nov 21) I’ll have kits and smd-boards available as I can get them tested and bagged up.

Very happy I managed to get one before you left @okyeron. Enjoy the trip, well deserved!

I got my Mouser parts yesterday. Does anyone know how much time USPS takes to get to Europe? Cannot wait to get started on the build.
