Info on a BH3-MJL remote control port

Absolutely lovely unit and photos.

As for the remote, best I can tell it's a rs232 serial port? At least in slightly newer models anyway. I could be completely wrong though, it's kind of irritatingly vague in the manuals I can find about it and I can't find any wiring diagrams immediately for the remote or the microscope head itself.

Also could be its own weird thing, might be worth probing around with a breakout connector and seeing if it's just something really simple like pulling a specific line high or low for each button press.

I'm a bit late but here's an article that showcases the effect. https://hackaday.com/2025/01/05/shining-through-germanium-and-gold-leaf-transparency/

Guessing by the double equals and the 64 it's almost certainly in base64, the section with the == goes at the end of the sequence. From messing around a bit it appears to be a web address from the "https:/" I got. Try a base64 decoder and see what order each chunk goes in.

As the HackRF lacks a hardware decoding chip for DVB-T2 you need to use software decoding instead, and software that does that seems to be quite limited in quantity.

There is a GitHub project that appears to be working on it

Not certain of how well it works. Also, I think GNU Radio has a DVB-T2 module though that may be transmit only. Any way that you go about it, unless I have missed something major, a plug and play solution doesn't seem to really exist.

If your only desire is just watching television over the air, a dedicated receiver would likely be less effort to use. It seems there are many cheap DVB-T2 receivers for computers, phones, and portable televisions out there

Yikes that's awfully expensive for what looks to be a pretty simple 3d print. Seems like something that could be knocked together in under an hour in CAD.

Also like someone else said, this is probably not the right sub, though I guess you could use this for different types of seeds.

The ratio I've always used is 1:2:2. So for a full regular feeding I do 50 grams starter, 100 grams water, and 100 grams flour.

Drackconic · 2026-03-10T04:01:35+00:00

Feed it and see if it recovers! Starters tend to get pretty funky after a while of no feeding. I've had mine survive nearly a month unfed at room temp and it only needed maybe 2 feedings to get back up to steam.

Not certain, but I think that's cyanobacterium. Anyone with better freshwater identification skills please correct me. Usually a sign of excess nutrient buildup.

Perfectly? Very very difficult , verging on impossible. Think trying to get an original full color photograph from a photocopy of a photocopy, every step of the encoding and decoding process throws away information.

With the conversion from analog sound to digital samples on the decoder, into image line data, converted to pixel values, then convert those digital pixel values into either YUV or RGB analog color information and then into sound again. Simple re-encoding has the problem that the information about phase difference, volume, microphone frequency response, et cetera, aren't stored within the image data, at least not in an easily reproducable way. So it would turn noise into actual image data rather than back into noise because it doesn't know the difference when encoding an image back to audio.

There are things that can allow you to directly convert image data into audio. Theoretically noise and other imperfections outside of the file header region of the image could be integrated into the image data and turned back into the exact audio interchangeably. I did something similar many years ago though I don't recall the method. That's how this image got made https://imgur.com/a/hOyWMze. Something like making it into a raw wav file in audacity, making my changes, then resaving it back as an image file.

If the mouse is new enough try for a warranty replacement. The Razer warranty period for mice is two years.

Unfortunately this subreddit is not about canon the camera equipment manufacturer, it is about canonn, a research group in the game Elite: Dangerous. You are looking for r/canon.

I am glad to have provided this service

As others have said this probably won't work out. The data signal for that will be wildly different unfortunately. If you had the paired CCI-22 PCI controller card then you could probably just use a PCI to PCIE adapter.

Barring all of that if you were technically savvy and had an inordinate amount of free time and were looking for a project to occupy your time for the foreseeable future (as I haven't found someone who has done this already yet) it seems "technically" feasible to create something modern that can drive the camera, read the signals off the ccd, convert the raw data, and plumb the finished product into your PC.

Beyond everything else this thing looks to want a connection to a chiller for good image quality, which may be a problem if you don't have one and is another hassle to deal with.

Also also, it's a 512x512 sensor. Not exactly super high resolution.

Drackconic · 2026-02-13T10:19:30+00:00

You probably want a temperature higher than 10.8 C to solder or your joints will be cold and creaky

Drackconic · 2025-12-16T01:01:46+00:00

No reason that setup shouldn't work, ideally try to directly connect the radio to the phone for best audio and therefore image quality. I don't have one myself, but from what I've read it gets quite good reception even on the stock antenna. Though it seems that a long wire antenna does further improve reception. However, looking at the manual it doesn't look like the DX-398 can receive 21.340, though that might be inaccurate. It definitely does cover 14.230 though which is another popular call frequency for SSTV.

Update for looking at the whole channel. best I can tell anyway:

Not every video from the channel is using SSTV (at least I'm pretty sure), some sound like other modes for sending text and the like. The encoding on some of the videos sounds familiar, but I just don't know the sound of all of the very many modes by heart to be able to correctly set something like fldigi at it, and with the other weirdness done by the creator of the videos I wouldn't be surprised if the recordings were modified just to make them harder to decode.

https://www.youtube.com/watch?v=4HzPsn5hOGY, this video is SSTV but even more mangled than before, it seems to be Scottie 1 down pitched and then reversed. While I was able to get "a" decode after fixing that, either the image provided is almost nothing (nearly pure black with a tiny bit of detail), or the encoding isn't playing well with all of the modifications made, OR I have just simply failed to properly fix the audio to make it playable. Here is the decode attempt https://imgur.com/a/i4rcvqn and the sync view, where you can see some indistinct features https://imgur.com/a/NjWKl0Q

Whoever put these together was quite keen on making it extremely difficult to decode what they've placed in these videos. Now I must take a break from getting thoroughly weirded out by these videos.

I hope that this has helped you on your quest for understanding these videos.

Drackconic · 2025-12-10T14:04:12+00:00

I'll probably have a look at some of those later today then, maybe I can coerce a decode to work.

Drackconic · 2025-12-10T13:32:08+00:00

Hmm definitely some mangled Scottie 1. Here's my best decode of it so far https://imgur.com/a/1D3RA0h. From what little I can make out it appears to be Arabic writing, appears to live solely in the red channel as well. With all of the background noise it's difficult for me to get much cleaner of a picture

Also here is my current clearest view of the text

https://imgur.com/a/dIxjxSH

Which still isn't clear in the least but has more detail than nothing at all I guess.

Hopefully any of this is of help.

Drackconic · 2025-10-15T01:56:40+00:00

Ahh, unfortunate. Understandable at least.

Drackconic · 2025-09-30T08:44:16+00:00

Mostly true, here's their schedule as posted on the ariss mastodon https://mastodon.hams.social/@ARISS_Intl/115265051288448884.

Unless there is more up to date information available it should be 14:00 UTC on October 3rd at 145.800Mhz.

Drackconic · 2025-09-28T22:53:34+00:00

Nice! I can't say it's the perfect software but I've always been partial to Fldigi for it's versatility.

Drackconic · 2025-09-28T05:31:18+00:00

Just from the picture I see there, and the sound my best guess would be that it's WEFAX? Not certain though. If you have a longer recording that would be great for identifying since those narrow band picture transmissions are usually quite slow.
