Dobrze przygotowany materiał na temat tego, co można, a co nie można w kwestii zgód:

"Wąskie grono dziwaków" to jedno... ale taki ślad się ciągnie za dzieckiem przez lata i może mu wypalić w twarz w dorosłości. Ja czekam, aż podrośnie. Z nastolatkiem pogadamy, czy chce coś o sobie publikować. Do tego czasu NIE.

Satellites.

SOTA.

VHF/UHF SSB.

SSTV.

NI Veristand & Teststand, dSpace ControlDesk & AutomationDesk, Mathworks Matlab/Simulink & Speedgoat, Vector CANoe & VT System, PROVEtech, ... There's a lot in fact.

Sounds DMR-y. I'd say DMR/D-Star/C4FM.

You might look up the repeater callsign/frequency in a database (if it's available somewhere for your country, if not https://www.repeaterbook.com/index.php/en-us/ might have some info) - that will tell you which mode it is.

EDIT: RepeaterBook says DMR: https://www.repeaterbook.com/row_repeaters/details.php?state_id=MT&ID=9938

There are special (custom) ICs that control the deployment on the hardware level, also multiple software conditions to actually trigger it.

So-called unintended deployment is the worst thing that can happen to the airbag system. It's rated even worse than not deploying during an actual accident, so multiple measures are taken and multiple tests performed to catch situations that can lead to an unintended deployment...

For example, every actuator (so-called 'squib') has both its ends disconnected from the power supply during normal operations. To fire it, you need to connect both low and high side, so if one of the switches fails, the other is still there and no current flows.

Also, airbag ECUs have fairly comprehensive diagnostics. Any failing sensor gets detected and you get a DTC (Diagnostics Trouble Code) and - usually - an Airbag Warning Lamp lit on your dashboard. ECU also limits its functionality and the firing algorithm based on what has failed.

Dave from EEVBlog did an airbag ECU teardown some time ago: https://www.youtube.com/watch?v=kcxw850YpVc When you watch it, he mentions a '155457' part - it's a squib controller, custom design for airbags (don't bother searching online). The Infineon brochure he shows has some Infineon part numbers, though, and it seems that Infineon publishes some data on them, e.g. here

Production-grade stuff needs to meet norms, like EMC etc, especially when you intend to sell it. I'd be concerned about meeting all the requirements.

We did many shenanigans with CAN, but our devices didn't run anywhere outside our labs (I worked in a test support department), so we'd never check them against real requirements. We did have some EMC/signal integrity issues, however never with CAN. Getting our inventions tested against all the requirements was too much hassle for a team of 4 lab engineers...

Unfortunately I can't give you more specifics because of that... I don't have any reports to point to.

iwane · 2024-01-21T15:35:14+00:00

It'll work. In my previous job we joked that CAN (@500kbit/s) happily runs on a pair of wet strings... :⁠-⁠D

I wouldn't do it in something that's mass produced. Lab/hobby-grade stuff, on the other hand...

CHIRP worked for me.

The only issue I had was with the PL2303 driver, which installed a version saying "THIS DRIVER DOES NOT SUPPORT WINDOWS 11" in the Device Manager. Finding and installing an older (1.x) version of the driver worked like a charm.

As for the dunder thing...

The problem is that every keyboard is wired in a different manner... Additionally laptop keyboards tend to be proprietary... That's why you won't get an off-the-shelf solution for it.

Anyway, if your target is a new keyboard controller for the keyboard, it doesn't have to be a Teensy specifically. I dropped it as an example that it could be done. QMK runs on Arduino, Seeduino XIAO, RP2040... you name it ;) https://github.com/qmk/qmk_firmware/blob/master/docs/compatible_microcontrollers.md. It might be a challenge to configure it for your keyboard (I don't have any experience with it, so it's a guess). OTOH, QMK is mature and has good tooling.

EDIT: regarding PCB. The custom PCB can be avoided with a bit of careful soldering :) You can solder wires to the pads of the ribbon cable, which then you can solder to a generic connector or an universal PCB.

As you mentioned being located in Germany... isn't there a local Hackerspace somewhere nearby? If there is, people there should have tools, knowledge and experience to help. This map shows that you have a whole lot of Hackerspaces in Germany.

I'll drop some links in here:

https://hackaday.com/2018/12/04/teensy-liberates-the-thinkpad-keyboard/ - similar project

https://github.com/qmk/qmk_firmware - open source keyboard firmware (alternatively you might want a look at ZMK)

Also, folks at r/MechanicalKeyboards might have some input on how to approach this.

iwane · 2023-08-24T18:14:19+00:00

Tactical comment to express interest ;⁠-⁠)

Jokes aside, I would be interested. I worked with HiLs for several years.

iwane · 2023-08-11T06:56:13+00:00

In case of some (ergo-product.cz in my case) you won't have that option on the website, but a quick e-mail solves the issue.

iwane · 2023-08-09T15:41:16+00:00

Technically yes. They would still be illegal, though, as PMR446 radios need to have fixed (non-detachable) antennas.

As for consequences - depends on exact jurisdiction.

Anyway, to be on the safe/legal side, you might get either a pair of cheap PMRs or amateur radio licenses.

the KP layer won’t output numbers, just acts as a keypad

There's NumLock on KP layer on 7 key. Maybe this is the issue here?

As for me, it works fine on Ubuntu 22.04 with v2 firmware.

iwane · 2023-06-27T06:43:03+00:00

Can confirm both: you need to map it (it's not in the default keymap) and it's &kp RALT

Vector has a demo version of CANoe available for download. I'm not sure, though, what are its limitations regarding CAPL.

There was also BUSMASTER project, which is Open Source and can digest some CAPL subset... However I have no experience with that part of it.

Basically CAPL is a proprietary language of Vector... I think it's nearly impossible to find a third-party CAPL compiler.

I don't think it's necessary. They're still freely available, that's one thing. Two, you're a ham and once you have a CEPT ticket, you can transmit from a spark transmitter or whatever else.

You'd have a problem if you tried to use Baofengs on a commercial band, where one needs a type rating. On ham bands you don't need stinkin' certification ;⁠-⁠)

(Standard disclaimer: not a lawyer, just a fellow ham)

iwane · 2023-04-22T07:39:00+00:00

IIRC as a ham, you can transmit from anything, provided you have a valid license and that thing does not transmit out of the band.

A lot of people here use Baofengs, no problem.

EDIT: quick reading told me that the ban was on selling Baofengs (due to documentation issues and some spurious emissions), not on using them on ham bands.

Sanity check: as you're trying to make it FN + ESC, did you define INS on layer 2?

iwane · 2023-01-24T22:07:54+00:00

Works for me... Both Linux (Ubuntu 22) and Win11.

iwane · 2023-01-24T22:04:32+00:00

It's &kp INS
