DIY LED Monolight

I’ve been quite focused on light building projects recently, but before I move on to other targets for my enthusiam I felt I had to make something with one of the Nichia COB LEDs I bought last year. The Nichia chips have a power rating of 37 watts, a quoted CRI of 95+ and what appears to be a fairly serious level of light output. All very good, but the thing that held me back …

Upcycled Monitor: LED Light Panel

When I was planning a light panel build using a reel of high CRI LEDs I bought recently, it struck me that repurposing one of the old 4:3 aspect ratio monitors that don’t get used any more, since everything switched to wider format, might be a good starting point. I wasn’t sure whether the backlights in these were LED based, but that didn’t really matter as they weren’t particularly bright in any case, so weren’t …

Recycled Polariser for 100mm Filter Holders

When I used a Cokin P square filter system I tried a few polarising filters, and ended up with one made by Stealth Gear which gave me pretty decent results. Unfortunately, since moving up from 84mm (Cokin P) to 100mm to cope with some of my wider lenses I’ve been having to make do without a polariser, as a lot of the 100mm versions seem to be tied to a particular filter holder and probably …

The Improved DIY Tubelight

After the unbridled fun of building my pipe light a few months back it struck me that since the build was in part my justifcation for buying a 3D printer, it would be a good idea to revisit the project and do it better using 3D printed parts. Now that’s the sort of challenge that could cause a load of buyer’s remorse if the result isn’t better and the build time a lot shorter. Risky, …

A Sheep in Wolf’s Clothing

Last spring, when I was putting together my anamorfake Pentacon 50mm lens, I had the overwhelming urge to get hold of a few more old M42 lenses of different focal lengths to hack in similar style. My project backlog has been a bit heavy since then, but while I was slightly stuck on the technicalities of the design for a couple of other projects I’m working on, I thought I’d clear my head with another …
