Shop stuff is great but it's always there. Time with family isn't.Okay, next post is some shop stuff. I promise.
I'm happy to hear all the joy you and your family are having.
Keep it up!

The other half is getting their friends into it as well so they have the social aspect too. So it’s amazing the racing club has taken off so well for them.
Nice!
You say, picking up and returning kids?! Are the parents not responsible for that? They should be grateful that someone teaches them something and entertains them.

Props for coaching. I am an L3 NICA coach so I get the time commitment.
It’s also one of the most rewarding experiences I have had. And my kids are just getting to be old enough.
Nice! I think Profoto had a similar dish back in the late 80’s? I owned that version. A lot better than lugging an HMI with a ballast. You should try to get a utility patent on yours at the very leastSo the other thing that I've been trying to do this summer is rustle up work because it's been a pretty slow year/summer. In some ways I feel like I'm captaining a sinking ship with my photo career but in another way I'm trying to appreciate the beautiful sunset while the ship slowly sinks deeper and deeper...
Part of what has always been fun for me is to invent or make new tools for creating photos. As cameras get better and phones replace cameras I tend to lean into what AI or an influencer can't do which is create light. Okay, AI is getting better but for the moment I am still more creative and I can create light in ways most people can't.
And one of the most fun things is to create new ways to modify light. One of them that we (the royal we which was Gregory Heisler and myself) loved was this very niche modifier from Broncolor called the Satellite. It was a giant parabolic reflector that you'd bounce a head into and it would focus that into a parallel beam that was very strong and, from a distance, indistinguishable from daylight.
I owned the smaller version for years but it was never intended for the newer battery powered heads that I use now and so I sold it and instantly regretted it.
So for the last couple of years where I've been doing more architecture and hotel work I have been scouring ebay for a replacement. They are exceedingly rare and almost never show up and when they do they want crazy money for them. And I'd still have to modify it. So I thought I'd make my own that works exactly like I want.
I found the reflector dish on Edmund Scientific so I just needed a way to mount it to my strobe head. The original design mounted the reflector to the stand and the head was mounted to that but the battery heads are too heavy for that.
I'd originally imagined making this adjustable with an Acme thread since I had some in the shop. When I welded the nuts to a tube I got the orientation wrong and they bound as a pair. Another option I'd considered but abandoned was a linear bearing. I'd ordered one from McMaster and decided to go with that instead.
The plan was to weld the struts to that machined center and each other and then weld that to a 1" aluminum tube so that the dish was the part that moved off the head. My dish was much lighter as it didn't have the plastic surround the original used.
Haven't welded aluminum in a while but Claude helped me dial in some settings. It's the conflict of AI stealing jobs but also being very helpful while doing it.
All parts fabricated...
Not winning any awards for those welds but they're more than serviceable for the job.
I originally didn't want to use the linear bearing because I was overthinking it and wanted to design a rack and pinion geared adjustment for the focus. The dish has a sweet spot - its focus point - but there's still a little room to adjust the beam pattern and spread by moving the dish to bulb relationship.
But thankfully the inherent friction of the linear bearing is more than enough to hold the dish in position and while it would be nice to make some kind of geared adjustment it's easy enough to push or pull the dish to focus it.
"Version 1" is designed to be used with both strobes and LED lights since I'm doing more video now. I've had a couple of jobs since completing this but they haven't needed this particular solution so I still haven't gotten to use it yet for an actual job but in testing it's doing just what I want...
You can certainly do more with light in here but there's no drama to this shot. No singular focus or thing to draw you in.
The same shot with a slightly darker exposure and a single strobe with my new reflector placed out in the middle of the back yard. Having a strong shaft of "daylight" that is streaming in the windows adds a sense of time and space. Time in that your mind knows by the angle of the sun that this shot is either morning or late afternoon. Depth in that there are deeper shadows and strong single light source that dominates the shot. Together they create an image that feels warmer and inviting.
So while the ship is sinking I'm designing fancy new oars, hoping to stay afloat by perfecting my paddling technique and enjoying the opportunity to invent and fabricate my own solutions to problems that won't exist in some near off future. The other benefit is that while you're actually working on something physical you are thinking and imaging other solutions along the way. That process is very satisfying and only happens while you're interacting with reality. Something AI can't quite do... yet.
