I bought a couple of these. Seem to be doing the job so far. D81 LTC3780 DC 5-32V to 1V-30V 10A Automatic Step Up Down Regulator Charging Module http://s.aliexpress.com/NbInqU36

It's to protect a TSL2561 luminance sensor and a MLX90614 digital infrared thermometer as part of a sky monitoring station I'm trying to build. I've ordered the £2 UV filter from eBay, so hopefully that should do the job.

Something like this should fit the bill I think: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F142873666801

Thanks. The window will only about an inch. I'm now thinking that maybe a basic luminance filter would work? Also, after a bit of googling, a piece of borosilicate would work if I can find a small piece for not much money.

I'm wondering if all transparent plastics pass IR or if there's any to watch for. I'm planning a build and need to make a small sensor window. Something like perspex or polycarbonate would be ideal, but if it blocks IR then it's of no use ?

I used to use imgburn, seemed to work fine for me.

Steel wool can be good for small gaps if you can keep it dry. They don't much like gnawing through the stuff.

Bought one of these a couple of years ago and it's been doing pretty well ever since https://www.amazon.co.uk/dp/B0166RCKXU/ref=cm_sw_r_other_apa_wlJwBbB655E24

XT Connectors might also be up to the job: https://www.componentshop.co.uk/leads-and-connectors/connectors/xt60-xt90-connector.html

Andy, did you ever solve your original issue of "rings of varying brightness". I only ask because I have seen something like this my self and it seemed to be a quirk of Photoshop. If I recall, it happened at different zoom levels. I think I was able to get rid of it by zooming to 100% but then the image didn't fit on the screen.

I think you can get them from B&Q https://www.diy.com/departments/grey-british-standard-b50-paving-slab-l-600mm-w-600mm/35830_BQ.prd Would be good to know what to put on the ground under it.

Thanks Peter, that sounds even simpler, think I'll give up on the concrete pour idea. Looking at the photo, it looks like a threaded rod with large washers? holding it together. What did you use for the fixings?

Thanks James. I don't have the drill bits for the size of the holes I need. I'd need to make holes for the M6 screws and M10 screws. What sizes would you suggest I buy?

I meant to ask, how have you secured to the pier to the ground? I can see a threaded rod that looks like it's going through the slab at the bottom, but how is the slab secured? I was considering digging a small hole and filling with concrete and submerging one of the blocks half way. This would help me get the height I need and would also allow the concrete to fill the first hole and anchor the block. I'm thinking of doing it in 2 pours. This first pour would be to establish the level for the block to sit on. Once set, I'd then place the block on top of the first pour and fill in the rest of the hole with the second pour. Think this would work?

Think I'll give this a shot. I'm just not sure what will happen when I start making azi adjustments. Is the puck just going to rotate in the opposite direction?
