I’ve posted this sort of content before and will do so again. This is the sort of thing I cobble together from found objects, spare parts, experiments in fabrication, and other brain re-setting exercises.

My center all touch-stone and tribute to the mechanical arts that compete at the Bonneville Salt Flats every year.

This particular rat bike object “Schwinncomotor” started from a rusting Schwinn Collegiate 5 speed bicycle I found at a yard sale for less than the cost of a meal at Wendy’s, coupled with a love for land speed record motorcycles and the nutters that pilot them bravely down one of the worst surfaces one can imagine on two wheels at high-speed. This is primarily a sculpture intended to look as though it was just back from the salt, uncleaned and suffering the pit-side hacking and clever re-engineering that goes on when teams make the best of their time on the flats.  It actually runs and drives. Add a bit of oil and gas, give it a pedal and hang on. It will do around 40MPH for anyone brave enough. For me, it serves as a touch stone to the universe of mechanical simplicity, a respite from the magic smoke electronics that makes up daily life in the shop here. The “Gear Head” art above the bike is also mine, from a used up race kart sprocket and a hammered aluminum mask from a wrecked floor plate.

A salt flat inspired creation. The flat panel light represents the salt, where the glare and reflection will burn you in places you’ve never been burned before.

For those who like details, the bike is vintage 1972, made in USA, that has been cut, chopped, bent and stretched savagely to create the parallelogram angles and trapezoid tube layout. The motor is new from a kit, a whopping 63cc screaming 2-stroke piston valve power. The front fork suspension system is modified vintage 1958 welded to a Schwinn blade fork that was bent to suit. This bike has seen a lot of torching and welding, from fork stem and handlebars to rear stays. The rest of the bike is custom bits made from fiberglass, metal or 3D printing (intake horn is actually plastic, as is the front air piercing element). The “salt” patina is white rubber sealant that looks the part but doesn’t flake off even on the tires. The seat is a composite of three different seats and 3D printed parts. I made no attempt to create a finished show bike. In fact every effort was made to do this with minimal use of measuring tools or finishing finesse of any sort. More time was spent making it look used up and old than it might have taken making it pretty – but that’s how I roll on this one. It was never going to be a show bike, its foundation was too far gone for that. Unlike those who believe the rusting hulk with tree growing through them in their yards are one day going to be pristine show treasures… I respect patina and recognize when the time for restoration has long past. Respect the rat as it were.

How does it ride? Well… pretty awful actually. The rake and trail make the front end floppy at low-speed. The motor and drive-train make peddling a bit hard. The front fork, being designed and modified, is not the sharpest handling part I have encountered on a bike – tending to be a little wiggly at times. Once the motor starts (pretty easy) it is fun, as long as you keep speeds above 20MPH to get the front end to pull in line. Other than that… it’s a sculpture, and is at its best sitting perfectly still.


Follow your passion and success will follow you

I find these “inspirational” vivications irritating and shallow. At the risk of being pedantic, allow me to explain.

In this case, the words evoke images of everyone loving what they do, and succeeding for it – with the inference of success pointing  to fame and fortune. Certainly, if you look at successful people in the public eye; actors, musicians, athletes, motor sports champions, internet and social media innovators, software developers, wealthy investors, etc…, they (more…)




Money does not buy happiness.

We’ve heard it before, and it is a compelling sentiment. Unfortunately, it is all too easy to assume that the basic needs of sustenance, shelter, security and comfort are a given. These cost money. Without food, protection from the elements, security from harm, and a modest degree of comfort, even a basic level of happiness is not possible. We live in a world (more…)

I have several fresh and brewing ideas about office lighting, putting new technology to work to make sitting in our little prisons more enjoyable and healthful. To put these ideas in context, and to consider real-world application nuance and detail, I’m collecting images of actual office spaces from anyone will to share.  I don’t need great pictures, just a quick snap with a phone that shows as much of the space as possible, perhaps with the lighting visible.

My office also houses the 3D printers. They need the clean/warm space to work best, and I like having them close.

If you have a moment, include any comment you might have about what you hate about the space, and the lighting, and perhaps what you like most? The spaces don’t have to be all cleaned up and tidy, in fact, the mess tells me as much as the arrangement.

I promise the images will go no further than a folder on my hard drive for reference in creating illustrations of model spaces within which I will be laying out alternative approaches and lighting products that might be applied.

You can do this all in less than a minute with a smart phone by sending me a an image to 414-241-5124, or I’ll send you a look in the future to what came from the effort, giving anyone who participates an inside peak of what I came up with and why.

Thanks in advance to all that participate!


LED Color Viewer

Posted: August 10, 2016 in Uncategorized

We’ve been working for several months on an LED Color Viewer that is easy to use, affordable and portable for use in the office and for taking it to client offices. Well, we’ve finished it at last.


The viewer contains 5 Cree CXB COB LEDs in 2700K, 3000K, 3500K, 4000K, and 5000K, each rated at 90CRI, that are selected with a simple selector switch. The viewer also includes a dimmer, so you can see the effect of light level on color. A rocker switch allows the light to be turned on and off without disturbing selector/dim settings. The viewer is easily folded up for storage and transport in an included carry case, which is padded, and includes room for the cord, as well as a pocket for taking along various color cards. It’s a perfect companion for the samples room, as well as viewing print media by graphic designers, and study by lighting designers when making presentations to customers.


The Lumenique main web site has been completely refreshed and revised to create a cleaner appearance that is easy to walk through. The original site was created (read evolved) over a period of 20 years, from its first appearance in 1995. The content was built up over that time to include a wide range of topics, from lighting and art, to BMW tuning mods and go-karts and our SCCA racing endeavors. That was before the days of blogs taking over that sort of activity. The new site is more focused and directed at our core business interests and competencies – and no longer requires a gamer’s commitment to navigating twists and turns to get an idea of who and what we are. The Lumenique Product Center has also been freshened up to match the new graphic design. (more…)
