Replaced DRV, seemed to be working on the bench. Iāve done 2 DRV replacements on these before that worked ok until I killed them with a power switch ground loop. Put it in my funwheel but didnāt have a chance to program it until later that day.
So I take off the lid and as Iām reaching in to plug in the USB C cable, it goes fucking crazyā¦ about 10 seconds straight of arcs and flames until I ripped the half melted power cables off of it.
The thing was, before this happened it was off but plugged in, so the power stage was live but control stage was off. It was sitting like that for around 8 hours before I somehow triggered it. I am extremely lucky that it didnāt happen on its own while I was away.
Iām thinking that the DRV reflow wasnāt the best and something was bad, whether I cooked the chip or some pads shorted out. I donāt believe the focer was to blame.
Iām just puzzled on how it worked fine on the bench with a PSU, and also fine while installing it in the board, but then explodes after sitting for 8 hours the moment I reach my hand over itā¦
That is an expensive hobby . I tinkered with it last year a bit, and you really need dedicated equipment to duplicate what you see online. A regular camera sensor filters out most of the wavelengths that nebulas emit, so you need dedicated cameras for the job, or compensate with an extremely long exposure time.
Yes. I saw a guy from London. He has an awesome channel, where he shows what can be done on a budget, and different ways to get through the atmosphere haze thingy to get a good pic.
I will for sure try one day.
Yeah Iāve gotten decent results with a ten year old entry level DSLR and a homemade tracker. You could probably grab the entire kit for under $200 these days. The only thing you canāt buy are dark skies (Iām in a Bortle 9 zone, and Iāve got to drive hours to find some actual dark sky, so I donāt bother)
Yeah Iād say astroās one of the few places where sensor size actually matters
Sure thereās all those algorithmic tricks the phone can do to improve the image, but thatās no match for more light (and therefore data) on the sensor. My camera lens is pretty slow and light pollution drowns out a ton of detail, so all the images above took several hours of exposures to get.
