  • Ultralight Tiny Cabin

    Man, that's really, really nice and well-thought-out. So many projects like that tend to grow and get sloppy in execution. It's clear you kept your vision and still integrated "salvaged" parts when appropriate. As a long-time professional engineer, I always keep in mind what dad (also an engineer) told me as a kid, "real engineering's not what you can put in - it's what you can take out" - maintain function with simplicity. You've done it, and also made it beautiful.

  • Greenhouse Made With...scaffolding?

    Wonderful!!We did something like this to keep birds and squirrels from the garden. I recycled a lot of nominal 1" manufacturing-cell quick-change bench & shelf configuration tubes and connectors into what we needed at home. Some good-quality birdnet and zip-ties topped it.

  • Cardboard Horn Amplifier.

    Well, each petal is "identical" to the other petals, not "symmetrical" themselves - they all have to be cut from the same desired face of the cardboard - there is a left and right side to each petal. This may be just a language detail.

  • Cardboard Horn Amplifier.

    Hmm - instructions aren't very thorough, and the rear phone compartment doesn't really assemble or "wrap" correctly. Also, seems like the phone compartment is sealed off from the horn volume? Tried with two phones - doesn't amplify or direct the sound in any noticeable way with either; three people listening and trying various positions.

  • Hammered Copper Coffee Table

    Gorgeous, gorgeous, gorgeous!! I had done a hammered-copper tabletop a different way a few years ago for a corner bookcase. I made a "soft" wood top from SPF pine framing lumber, and covered it with roofing copper. That's when I learned that my ball-peen hammer had to be mirror-polished not to leave a mark!

  • Continuum - Slow Motion LED Art Display

    I love it! I'm going to do this for a simple reason. In the late '70s, in electronics class, I made a kit of a device called a "color organ". It took an audio signal; split it into three frequency bands, like a conventional re-amp crossover. When any of the frequencies hit a settable "volume" level, it triggered an SCR to power a 1-2 amp 120V circuit. To these outputs, you plugged in three strings of Christmas lights, each string a chosen color. The lights would flicker with the music, and we actually got to where we could recognize songs by the patterns!Then one would build a 2' X 4' box about 8" deep, mount the Christmas lights against the back, and add a sheet of translucent A19 or A12 fluorescent troffer diffuser in front. Listening to music was never …

Listening to music was never cooler than those highschool nights in my bedroom with this as the only light.I think this project will be as cool, as I approach my 60s as an R&D engineer in commercial/industrial LED lighting - I have the patents on the 2x4 LED retrofits in your nearby Target stores.So cool!

    Well, those electronics things were a LONG time ago. Here's an Arduino-powered docking-light system from Battlestar Galactica on my carport - Daughter on a moon-walk think when they were younger (she turned 23 yesterday!)Device to show the kids how card it was to even power a 25-Watt lamp - Multiple-motor scooters - Some pix attached of two dashboards I've made recently - one for an MB rally-style car; the other for my '70s kit car that I hope one day to get over 200 at the Texas Mile - Forrest in Atlanta

    Gs500 Cafe Racer

    Wonderful father-son project! I just spent this beautiful Sunday in my shop with my son (19); me doing electrical and woodwork; he doing metal work. Couldn't be a nicer time - he's home from GA Tech due to the virus.

    Raw SS is certainly the better material. I have a tube bender that has an available mandrel attachment to bend thinwall (Rogue Fab). When my TiG skills are better, I dream of making SS equal-length headers for my V-12 MB - Kooks want $8K for custom ones! I do have a second regulator for experimenting with back purging.

    Love it! Great attention to every detail, and thinking through all the steps and components.I got carried away on my exhaust as well - mild steel from many bends and then Jet Hot ceramic coated

    That is such amazing, inspiring work - just freakin' super - perhaps the best thing I've seen here.

  • Quarter Iso-grid Cardboard Longboard

    You MUST glue the all the edges of the core to the outer acrylic faces - otherwise it's not really a "structure" in the engineering sense - it's just three things layered together - the truck bolts are not sufficient.Gorgeous look and execution, though - I'm going to play with that grid concept!

  • I do this professionally (R&D industrial / commercial LED fixtures). Seoul Semiconductor does something similar with their Acriche series of "AC LEDs". The reason this is tough to do in an uncontrolled environment like these LED strips is that LEDs are incredibly current-sensitive, and their forward voltage varies with the current to some extent. Super-hard to balance multiple strings to run on AC - and remember that the "peak" voltage of an AC sine wave is separated by a lot of time below that peak - and the LED string won't conduct - so a lot of "off" time in the cycle - much more than the "on" time.What one actually does is to have several groups of LEDs that turn on at different points in the cycle as the voltage ramps up and down - but th…

I have some early prototypes in my kitchen, and if you pour sugar or get the faucte dripping just right, they motion will "strobe" and freeze - and that's at 120 Hz.It's important to keep flicker up to a minimum of about 3KHz for physiological reasons.I'll attach a pic of my similar garage lights, with an Arduino sequencer. One LED is visibly out - can anyone find it?Here's a link to the motion video -

  • Cool! I made mine sequence from one LED driver, or I can turn them all on with eleven drivers (one for each rafter) for bodywork and detailing.
