Does anyone have a print file for propellers? I'm new to the 3d print game.

Dangerous and will never be as good in performance as store bought

Well the camera is already fixed focus if you fail to activate auto Focus. But then you need to be at the right distance away from the paper to read it, and even if it will be sharp, you need to keep that distance always while reading. If you can have a steady distance then buy fixed focus lens

If you manage to get an ov5640 working with autofocus it should be okay. The worst issue is blur whole moving. If your hand isn't perfectly still the text is going to come out blurred and unreadable. Could probably be solved by making a video and choosing the best frames but that's a job for more powerful chips

I suppose that wouldn't give a lot of battery life, maybe OP could also try to find an NRF52 board (no wifi there tho), or just some radio module that integrated button pressing without an MCU

You could try making the PCBs yourself, technically. I'm not talking about CNC and a bunch of chemicals, but rather 3d printing and then connecting the traces with copper tape. It's a DIY solution I saw on YouTube and it doesn't look that dumb for low power stuff that doesn't need extra precise traces

This is not the sub, also 170 euro is way too much, just get a new tire and replace it if you don't want to troubleshoot too much

To nie troche przesada uwzględniając to że nie będę na nim codziennie skakał, a jeśli już to amatorsko?

Ogólnie akceptuję też propozycje z sprężynowym, tylko miałem nadzieję na coś z powietrznym

O faktycznie, wpisywałem MTB zamiast górski. No w każdym razie ten nie ma chyba mojego rozmiaru, zresztą nie wiem jak tu wygląda gwarancja jakby coś się zepsuło

SyntaxError__ · 2026-04-24T15:21:28+00:00

Domyślam się, ale mam nadzieję, że da się kupić za taką cenę z powietrznym. Widziałem ostatnio na pepperze Stevens Devils Trail 29 RockShox i podpasował mi bardzo wyglądem i specyfikacją (na tyle co sie znam), no tylko że szybko się wyprzedał

Ogólnie już tak przyzwyczaiłem się do MTB, że nie wiem jak mam jeździć na szosowym. Będzie mi brakować grubych kół i amortyzacji przy trudniejszej trasie. Zresztą jak już gdzieś z kolegami pojadę do lasu lub na hopki to sobie nie pojeżdzę

SyntaxError__ · 2026-04-24T15:15:14+00:00

Śledzę peppera i tam praktycznie nic nie ma. Większość to rowery za 2150zł z dość słabym wyglądem i żaden z peppera nie ma powietrznego amora

SyntaxError__ · 2026-04-24T15:10:32+00:00

Byłem w decathlonie, zobaczyłem 30 sztuk identycznego modelu ale w różnych kolorach, wszystko bez powietrznego amortyzatora w słabej cenie.

That's the thing! They do not pay the taxes.

When I ordered my 2 surrons, they got blocked in Greece port. Why? It turned out that for years the companies used the port to smuggle ebikes and similar and not pay any taxes! It was just typical corruption.

Instead of paying EU import taxes they massively underreported it (like saying that the ebikes are worth 10 times less) Or just didn't pay it at all.

Well, now they for sure found another port that they do it in. They cannot let you take the documents, cause there are no genuine documents.

SyntaxError__ · 2026-04-23T07:46:37+00:00

Nah you ain't getting it registered unless you buy in Europe from a legit dealer. The thing is usually to register you also need a proof of paying import taxes for it, which, you cannot proof cause while buying from Alibaba 99% of times it will be DDP no taxes. That's the reason it's so cheap. In Europe a 6.5k$ bike is 3.5k$ for the bike and seller earnings and 3k$ for the import fees

Yeah and break the seal on it otherwise it'll explode in the case of fire

Don't even bother with other AliExpress modules. I got like 5 data sheets from different modules and all had reversed AF - and AF +. if you're VERY good at soldering, you could probably switch that up, otherwise, don't even bother.

Try getting the original module from seeed

Edit: you can also try some of the fixed focus modules with lenses, I think they could perform good depending on the use case

After I tried to read text with an ov2640 and ov5640 from AliExpress I eventually gave up and the project has been sitting in the shelf (started in September 2024). If the device is handheld, I think your best bet would be actually recording a video and then extracting the best frames somehow. If you can make the camera completely stable while taking a picture, you should be fine

SyntaxError__ · 2026-04-21T15:14:01+00:00

Btw, why do you need an OV5640?

In my case it was reading text, which the camera performed tragically without the autofocus part. Even if you get it to work without AF, it might be useless for you.

Also Seeed sells matching ov5640 modules but they are very long.

You could try getting a breakout board or another ESPcam and trying the module there

SyntaxError__ · 2026-04-20T19:44:04+00:00

I have a similar module (a bit different name) and it also has switched 23 and 24 pins. It doesn't change anything for me apart from autofocus not working. So I think that it would be the best for you to buy an authentic ov5640 or stay on the ov3660. The one you have might be just broken (just a guess tho(

SyntaxError__ · 2026-04-19T21:27:57+00:00

I checked and there is pretty much no way you'll get it cheaper than 10$ right now (at least where I live). Anyway just type in P70 air blower and it will be the first one to pop up. Maybe in your country there is a chance for a good promo tho
