Machine Your Own Ring Light

November 9, 2010 by James Munns 18 Comments

[Alan] acquired a stereo microscope from eBay, and decided to save some more money by designing, machining, and assembling his own ~~arc reactor~~ ring light to go along. After finding an LED driver board sitting around as well as ordering some surface mount LEDs, he set about using a lathe to cut away a block of lexan, making sure to include slots for the lights as well as the microscope mount point. Follow the link to see the detailed build photos, as well as some comparison shots with and without the ring light.

A month or two earlier though, and [Alan] would have had a fantastic start to an Iron Man costume.

Unreal Speaker Build

October 27, 2010 by Mike Szczys 50 Comments

These speakers are hand made and almost one of a kind. [Lluís Pujolàs] didn’t come up with the original design, but he sure did an amazing job of crafting them, including an eleven page build log (translated). They’re called the Odyssey 2, after the original design. The shell-shaped cavity on the bottom was built as a wooden skeleton first, then covered over for the finished shape. But the mid and high range enclosures were turned on a lathe from wood glued-ups. A serious machine shop is necessary to do this kind of woodworking. The bases are poured concrete, impregnated with lead beads to help with vibration isolation. At 330 pounds each it’s understandable that he tested them on wheels before parking them in their final position as seen above.

Replicating Connectors By Machining PVC

April 21, 2010 by Mike Szczys 12 Comments

[Alex] bought a hang on tank filter for his aquarium. Unfortunately it was made for a different water level than he was using and didn’t have the ability to adjust that he needed. Add to that the non-standard pipe sizing which compounded the problem by making it difficult to extend the intake and output tubes. He overcame this by machining PVC pipe to match the stock connectors. After turning the PVC on a lathe he added a neoprene o-ring and painted the assembly black. The new connector allows standard size PVC fittings for easy changes in the future, and it keeps his turtles healthy and happy.

The folks over at NerdKits got a shiny new Smithy 1220xl lathe/ mill. They found, however that adjusting the Z axis wasn’t as accurate as they desired. They decided to resolve this by installing a digital caliper and an LCD interface to display the adjustments. The writeup is quite detailed and the results seem to work great.

Industrial CNC Controller Retrofit

December 28, 2009 by Mike Szczys 5 Comments

[Jerry] had a beefy CNC lathe whose controller wouldn’t respond. He cracked open the case and found a large scorch mark surrounding one of the servo controllers. Rather than just replace the IC and still be stuck with a 23-year-old controller he decided to retrofit the machine with modern controls.

The journey from a brick of steel to an incredible machine is fascinating. Using a combination of commercially available boards like the ModIO controller and custom-built circuits, he cleaned up control signals and give life to the lights on the original faceplate. The machine is now working beautifully with a new monitor, automatic oiling, and wireless connectivity.

Ah the beauty of watching molten solder pull SMD components into place. Yeah, we’ve seen it before, but for some reason it never gets old.

The glory days of wardriving are certainly behind us but if you’re still hunting in certain areas for access points you can leave the laptop at home. A homebrew program called Road Dog can turn your PSP into a WiFi search device. You must be able to run custom code to use this app.

Ferrofluid is our friend. But having grown up watching the Terminator and Hellraiser movies we can’t help being a little creeped out by the effects seen in this movie.

Follow along with the NASA astronauts in this 20 minute HD tour of the international space station. It’s a cramped place to live but we can’t help thinking that it looks incredibly clean. After all, where would the dirt come from?

How are your woodworking skills? Can you take a wooden block and turn it on a lathe until you have a lampshade 1/32″ thick? We’d love to see how these are made, but imagine the artist’s reaction when hours of labor are ruined by a minuscule amount of misplaced pressure on a carving tool. Patience, we’ll learn it some day!

This video from the past that is about the future of travel does leave us wondering why our cars don’t have built-in radar for poor visibility? We’ve already realized the rear-view-mirror-tv-picture, but we’re going to need your help before the flying police/fire/ambulance-mobile is a common sight. Oh, the fun of seeing a high-tech push-button selector 3:30 into the video. Perhaps the touch-screen was a bit beyond the vision of the time.

Sometimes you have so many servants you need to find creative things for them to do. Only the most discriminating of the super-rich employ a person whose sole responsibility is to erase and redraw the hands of a clock each minute. This video is obviously a result of the global recession as the live time-keeper has been let go; a looping recording took his job!

Last time we checked in with [Marco Tempest] he was syncing video over multiple iPhones. Now he’s at it again with an augmented reality setup. A camera picks up some IR LEDs in a canvas and translates that into information for a video projector. We’d call this a trick, but it’s certainly not magic.
