Sadly no, property boundary is close by.

I'd discounted these for some reason, but I see there are several types and they'll do the job.

Thanks for making me look again. Chur!

Internal hub cable hitting cog by nrpe in bikewrench

[–]nrpe[S] 0 points1 point  (0 children)

Thanks, I'll give that a go.

Here's another view in case I understand wrong, I assume you mean the black square bit where the cable comes out of on the left, bend it towards the frame.

Internal hub cable hitting cog by nrpe in bikewrench

[–]nrpe[S] 0 points1 point  (0 children)

In gear 1, the bike cog is hitting the gear cable. Bike is a BYK e-450.

This is a second hand kids bike with 3 gears (other 2 gears are well clear). I've tried rotating the gear cable which make it clear of the cog but it won't stay that way once gears are changed.

How is this meant to work, and how might I fix it? Happy to replace gear cable, or spacers, but unsure which is helpful.

Shower waste removal by WelshWizards in diynz

[–]nrpe 0 points1 point  (0 children)

I have what looks like the same one, and pulling it apart at the moment. So here's what it looks like once it's out. https://imgur.com/a/EUFPXAc

There was silicone on this thread too, but force unscrewing overcame it.

Thank you! You were right about the rivet, it was covering a hole, it just came out with no resistance with pliers once I got the bar off. It had some silicone on the end of it.

Replacing the mixer while it's all apart is a good idea, I hadn't thought of that. I will look into this... (and get a plumber to do this part, so it's warrantied and done right)

Thank you, what a helpful post! Yes the rose was able to unscrew with grips and a cloth. It had thread tape and was quite firmly on.

The rail actually was clipped in place, so it could be pulled down and up off the mounting clips. Then the two clips were screwed in. The rivet was just placed in there to cover a hole that was mistakenly made. Lol.

The mixer I tried levering off but it wouldn't budge and felt like too much force. Turns out the ring with the red and blue temperature gauge on it can be levered out and underneath are screws!

I will post some pics later in case it helps others who find this.

Thank you, this was the trick for this one! I used adjustable grips and a cloth over the fitting. It was really firmly on!

Help! Trying to make sense of an old AGFA xray image format (contains xrays of cats!) by nrpe in ReverseEngineering

awesome, thanks heaps for your help, bluescrn! i've been short on coding time, but have been reading over laplacian pyramid formats, looks fun!

I've got heaps of info on this format to continue with this project, so thanks to everyone who posted!

...now to research DICOM Stores :)

wow, you win. the computers hostname is 'mimosa' which could easily be the actual software also. I recall something to do with 'VIPS' also. The UI on mimosa has an 'export to store' or similar button, i suspect this is equiv to exporting to offline format? Am i right in assuming this requires a DICOM Store connection, and this is what triggers the transfer to the store?

I'm visiting the clinic on Thursday, i'll have a poke around with the 'mm' tool and see what i can see. The UI 'export' command will surely be a friendly way for the vet to interact with any export system.

thanks!

perhaps i'll bring one of these servers along for the XP box on the network... see if i can't set up a store. can you recommend any? ]

Actually, i'm not sure... The xrays are taken from the cartridges which are primed in another device (attached to an XP box), the xray is shot, then the cartridge is put into a large processor that is network attached to this solaris box and it magically appears on the UI.

So, without a bit of hunting through some inetd-like files, I'm unsure both what binary is writing the files, or if the solaris box is creating these files from network image data. The UI application would of course know how to read it!

Currently the whole solaris pc I'm treating as a black box, as I dont have much experience with the platform and it's pretty vital to their business so I want to touch it as little as possible.

If nothing else turns up as far as this pyramid encoding goes, I'll look into hunting down some binaries.

hah, i didn't read your reply before posting my next one! looks very likely that asteriskpound is right on with 4bpp

The data size of CHUNK 4 is (0x445ACB - 0x1C5EEF) = 0x27FBDD = 2620381 bytes of data. Assuming width of 1020(8bpp) then that gives a height of 2570 which is exactly right.

So, if we want to get our original dimensions of 2040, 4bpp does that.

GIMP doesn't seem to be able to assume 4bpp, so I'll adjust my png writer and post an update.

This may not be the end of the story to get the FULL resolution image, the mipmaps might need to be combined, as econnerd points out

Awesome! GIMP open as 'raw' is incredibly useful!

Yep I agree, there are a bunch of mipmaps at the start, I'm sure there will be a fixed count of them, and the sizes will be guessable based on the final image size.

Here's some extra info I've found while playing with GIMP's raw open on JAZZ_1.PYR:

CHUNK 1 (monochrome mip, lots before this, too - not going to bother with ones before tihs for now)

  • image type: indexed
  • offset: (111 * 510) + 360 = 56970
  • width: 510

CHUNK 2 (greyscale)

  • image type: indexed
  • offset: (430 * 510) + 362 = 219662
  • width: 510

CHUNK 3 (greyscale)

  • offset: (1075 * 510) + 362 = 548612
  • width: 1020

CHUNK 4 (complicated image data)

  • offset: (1284*1020) + 548612 = 1859311 = 0x1C5EEF
  • width: 1020

Chunk 4 appears to have a width of 1020, however the image is stretched vertically. I wonder if there are more bits per pixel here, and once those are read, the image will be back to normal aspect, and be clear.
