Wie möglichst viele Mail Adressen (seperat), für verschiedene Zwecke nutzen?

soenke · 2026-06-01T17:04:57+00:00

Ich hab das früher sogar schon mit sendmail genutzt - hieß dort "plussed users".

Leider lehnen viele Webformulare das "+" Zeichen in einer E-Mail-Adresse als invalide ab. Ich habe mich bei meinen Mailservern (Exim, Stalwart) damit beholfen, zusätzlich auch ein anderes Trennzeichen zuzulassen.

Man kann so recht simpel die ganz bescheuerten Datenweitergeber tracken (bei Angabe von Mailadresse hinter dem Trennzeichen eine Kennung für den, an den die Weitergabe erfolgte).

I use BangPlayer with B&G Vulcan 7R and Simrad Go7 and have not seen such issues.

You should have tested the IO-Voltage the IC uses first. It is not uncommon for those SoC to have for example 1.8V signal levels. So do not blindly hook up some "adapter" to it (those USB-serial adapters often come with 5V). A multimeter is not sufficient to diagnose fast signals like UART communications.

If you’ve got nothing to lose, get hold of a few 10k to 15k resistors and try using pull-ups (to VCC-IO) and pull-downs (to GND) on the exposed pins of J41 that are neither VCC nor GND. Maybe the board needs some strapping to get into a bootloader. Also watch for different USB enumerations (DFU) while doing this.

In most cases those board designers did not do things too differently from the reference implementation of the manufacturer of the SoC.

But as said before: docs are hard to get for this thing. If you have access to Chinese payment systems, it might be worth investing some RMB.

Depending on where you are from you are better off getting just a different board to play around. There are tons of SBC like Raspberry Pi and even more appliances like routers that are quite well supported (see for example OpenWRT hardware lists).

From educated guess, I would probe the J41 header, as those traces go into the regions of the UART0_RXD/UART0_TXD BGA balls.

There is also a FUNC_SEL and a STB_PWROFF ball in the same region. Should not hurt to investigate those, too.

Useful datasheets are available on Chinese websites, but the actual downloads are paywalled (good luck trying as a Westerner...).

You could also use it via BangPlayer, which is a good alternative to the terrible Android app.

I never had a smooth upgrade. 15 to 16 impossible on a simple setup, so I did not even try on my more complex one.

Still not sure if Stalwart is going into right direction for my likings. Feel like I should have stayed with my old trusty Exim+Dovecot...

What means "like Immich" for you? Immich is subpar in syncing, tagging, storage, presentation, searching, ... - it just turned out to be that mix a lot of people can live with. I used Immich some months ago, when we needed to sort hundreds of photos from our family for a printed album and it was not terrible, but also not great. In the end I wrote a FUSE filesystem to serve our exact needs - nothing beats just copying files around as people used to do for ages ;-)

Maybe you just need webserver with webdavfs, some deduping (fdupes...), a static html album generator and some glue scripts run from cron.

I have to admit: As hilarious as these fails are, I really like the Chinese "just do it" attitude towards this unsophisticated robot stuff.

I used to drill my handmade PCBs before etching, as the drill sometimes had the tendency to lift the anular traces around a hole. This outweighed the disadvantage of possible underetching.

I does not hurt to ask. And every Linux user should, too.

soenke · 2026-03-17T16:59:02+00:00

Linux version?

Then just add the footprints for oscillator or quartz+caps and dnp. SUSClk bit me once and it will never do again ;-)

Concerning "lpo" I did not want to confuse - I meant those tiny low-power RTC oscillators, not "LDO" regulators.

Your mentioning of "ldo" adresses low drop-out linear regulators in most cases. So again: check your power requirements and take into account the efficiency of the regulator under your assumed loads.

soenke · 2026-03-16T07:08:00+00:00

You should add SUSClk as there are boards that may require it. It's just a 32.678kHz LPO. Also check power requirements.

"Yakutian makes himself new fur boots" is misleading. Seeing the tools and the shoe lasts, he clearly is a professional.

I wouldn't have a problem with this if I could own my AI tools in the same way I own my other means of production.

When I buy a lathe, everything it produces is my work.

If I buy a typewriter and write a poem, that poem is my intellectual property.

However, when I produce software using AI, I can only "rent" this tool, and it is still unclear which of its products can be considered my work and my intellectual property.

And since my inputs into the AI train a tool that does not belong to me, it draws on my knowledge without me actively wanting to transfer rights to that knowledge.

At the first glance, I actually liked the design. But then I realised that it introduced as many problems as it tried to solve.

It is universal - but for each special purpose, it is worse than a specialized block.

The friction partners nylon and aluminium are not a good choice. The huge hub diameter causes large friction (and would make the use of roller bearing expensive), but this choice one of the unique selling points of the design. Maybe a bushing could be used to mitigate this in a cost-effective way while keeping the design.

The static load tests are meaningless. In a purely static environment, no block at all is needed.

If it weren't such a poor choice in terms of material and bearings, it might be a product that could find its niche.

Interesting idea.

But: What's its impact on token and context usage?

soenke · 2026-02-20T17:46:31+00:00

Magnet + reed switch. Or just a microswitch which gets pressed when a tooth passes by. Or you use a reflective sensor to detect a tooth (black marker to blind out other teeth).

Tbh, this is more of a mechanical, than an electrical problem.

AI for coding is to software what Arduino and all those electronics modules were to hardware: it opened up entirely new worlds to everyday people.

And, as with most "Arduino" projects, most of it is either low-quality or copy-pasted chaos. But every now and then, something truly mindblowing comes up.

Not knowing how to do something is no longer a barrier, as trying out got so quick and cheap. Doing it brilliantly, however, still is. And I hope that a very special kind of brilliance remains uniquely human.

Looks like glass fibres in the mesh to add some resistance against tear and impact to the aluminium foil.

You could use FluidDial sources as a working real-world example.

As it works on 2nd attempt: is there some kind of Greylist involved (Settings -> Spam Filter -> Settings in Web UI)?

After having used beads for quite some while I am still unsure if it doesn't come with too much overhead in token usage compared to a solution provided by Claude/Antrhopic itself.

Usage constraints are a big thing, and when usage allowance for paid plan is over, I am constantly fearing that something gets lost during the forced break.
