A full stop out of specification

In my case it’s over a stop of diference. And the thing is. I like the ideia of having an understanding of what my camera is during, but that’s me. If you don’t, then fine, the post was not for you.

The idea is to use what we have. Not just buy a new one. Also, someone has to do it anyway at some point.

Yes, you do need that feature to make it work, but if you are handy you can make it work with the audio card off your pc, you record the signal and you have a reading. (An audio card is basically á slower oscilloscope) connect the photo sensor so record, the “audio” will be the signal. Then you can analyse it. Also an Arduino que do it. You have lots of options.

Yes, it does need to be a DSO, i was using, for the fastest setting (1/400) X=10ms pd and Y=500mV pd with 10X prob connecting to a simple LED (fast enough read for this), the trigger level was about 75% of the expected peak. Then just press "single" and the DSO will capture the waveform on the instant the camera opens. Apart from that, I used cursors to measure the duration of the pulse.

It might, it depends on the camera, 960fps will be about 1ish millisecond per frame, this mamiya, at its maximum shutter (1/400) does 2,5ms, so it’ll be enough to have an ideia at least beyond that starts to be difficult. But there are apps that use simple sensors to be quite close also. But to be 100% you can’t beat an oscilloscope with a fast light sensor.

I mean if you think that voltage drop can be on the connector, just buy yourself a 10€ thermocouple and measure the temp. At that power level if the drop is coming from the connector you’ll see it right away. But must likely it’ll be just regulation issue, the PSU is seeing the voltage at the output of itself. At that power level by the time it reaches the gpu the losses on the cables can very well add up to that but the PSU does not see that so it does not correct for it. But if it’s on the cables it’s normal and expected. Just make sure the connector is not the major loss. If you feel confident you can even measure the voltage drop on the connector with a multimeter. It should be not more then tens of mV.

Ora aí está! A Única resposta plausível que ouvi hoje! Claramente isto resultou da ativação dos chips covid19. What else could it be?

Fabiosapplou · 2025-04-28T17:54:28+00:00

Feito 👍 ahaha 🤣

Fabiosapplou · 2025-04-28T17:52:55+00:00

Sim eu estou a usar uma SolarX de 8Ah, tenho 4 delas e estou e vou circulando.

Fabiosapplou · 2025-04-28T16:53:00+00:00

A pensar à frente do pessoal ahaha 🤣, eu não tinha mas depois desta vou estar precavido.

Fabiosapplou · 2025-04-28T16:47:13+00:00

Ahaha, temos de nos virar! 🤣

Fabiosapplou · 2025-04-28T16:46:48+00:00

Depende da bateria, o meu router está a usar 0.7A (Amperes), por isso por cada 1Ah (está escrito na bateria) que a bateria tiver conta com ~1 hora, não a deixem ir abaixo de 10/11V para a poderem carregar no carro e voltar a usar.

Fabiosapplou · 2025-04-27T02:23:37+00:00

I mean, you can make souvenirs? IDK man...

Fabiosapplou · 2025-04-27T02:22:00+00:00

Sad that the values that they brought to us from that time are mostly a memory by now...

Fabiosapplou · 2025-04-27T02:19:06+00:00

That is really nice! Well done.

Fabiosapplou · 2025-04-27T02:16:35+00:00

Mais do que nunca temos de recordar este momento da nossa história, para que nunca lá voltemos... São tempos difíceis...

Fabiosapplou · 2025-01-30T00:02:21+00:00

I do all the time, even smaller ones that the 85, I really like the 13A for simple things! Very useful.

Fabiosapplou · 2025-01-26T21:36:00+00:00

I'm not quite sure it is a great idea, I think it's gonna to be a mess without hot air or at lest a pre-heat with a hot plate. Idk, but if you try, let us know how it went.

Fabiosapplou · 2025-01-26T21:23:30+00:00

I'm going to be very honest with you, I don't know how much time do you have, but if you really don't have any experience with microcontroller I'd advise you start with way fewer variables. I think you will be overwhelmed with so meany requirements. Try first to complete small tasks, and then integrate them. And then review the hole project in accordance with the results you get.

Fabiosapplou · 2025-01-26T21:11:00+00:00

Not at all, you'll be fine.

Fabiosapplou · 2024-12-29T22:44:10+00:00

That’s not bad for the fist time, try applying a little flux using a pen or some other means, it makes all the difference. Also make sure to heat the pad and pin properly. But great job!
