Vintage computer kits

Replica1Ds
Jason writes -

Relive the glory (gory?) days of early computing with these two great sites for vintage computer kits. Briel Computers has kits for the Apple I (Replica I) and the Kim-1 (Micro Kim). And, Spare Time Gizmos has a has a kit for the Cosmac ELF (ELF 2k). These kits are great ways to learn the basics of computer architecture and data organization.

Nanocarbon from Graphene to Nanotubes to Buckyballs

Nanocarbon Intro
John writes -

I've got a new posting to my UVA Virtual Lab website entitled "Nanocarbon: From Graphene to Nanotubes to Buckyballs." This page differs from most on the site in that it actually downloads Shockwave 3D models to the user's browser where they can be manipulated and modified. The overall presentation explains how different types of bonding leads from cyclohexane to benzene to graphene to graphite to Buckyball structures, and how the bonding affects electrical conductivity. The presentation also introduces some of the terminology readers will encounter if they websurf into nanoscience research websites.

Simple homemade tilt activated switch


imagitronics writes -

I started working on my next project tonight and realized that I needed four tilt activated switches. I wasn't exactly sure what would make a good tilt switch. The majority of online videos and tutorials for tilt switches were either undocumented, mercury based, or actually accelerometers. Luckily I found these small steel hooyahs. I have no idea what they were actually designed for, but they make pretty handy little switches.

Doublet amplifier

Sam writes -

A few weeks back I wrote up a blog about the Doublet Headphone Amplifier which lets two people listen to the same audio source with independent volume controls. I got so many emails from folks who were interested in building one that I decided to make another run of the printed circuit boards - and they've arrived!

If you want one of the PCBs, email me with your mailing address and I'll drop one in the mail to you at no charge. You'll have to supply the parts and the Altoids tin.

Circuitboard earrings

Earrings1
Earrings6
Craig writes in -

Here are some circuit board earrings I've been making for years. Cut a circuit board with a Dremel cutoff wheel, sand the edges straight with a belt sander and then ultra-fine sand the edges and corners smooth. Since it is fiberglass, you must coat the raw edge with a clear nail polish, and make sure there is no lead solder on the back side against your ear. Wear eye protection as always and a dust mask is good too when cutting/sanding fiberglass. The studs and backers can be purchased at a fabrics & craft store by the 50ct. bag. The perfect jewelry for the computer geek or electronics nerd!

With a 35W Epilog laser 40% power, 100% speed with a 600dpi vector art image (AI) works great for laser etching an iPhone. The material on the back is a nice plastic that etched white-ish. Special thanks to Dan for experimenting... :)

The sideways bike

sidewaysBike.jpg
Being dyslexic, just looking at the videos of Boston-based bike-builder Michael Killian's "sideways bike," makes my noggin throb. You ride and pedal the bike sideways, and steer front and rear (independently). His site has numerous videos, pics, and links to media coverage of his various bike projects.

Acra mill plus

Cutoff Saw Display1
Kaden writes -

So I was hangin' with one of my hardware buds last night... he's my go-to guy for obscure and/or drool worthy toolage. Last time I visited he showed me a bunch of Orthopaedic surgery tools from the '80's that he'd scored from an estate sale in the interior. Cripes, Phil, ya wanna have nightmares?

Hold something called a Femur Reamer in your hands. That's all you need to do: give your subconscious a few hours to ferment the experience and you'll be waking up in a cold sweat at 30 minute intervals for the next 6 nights.

Last night the talk turned to 'rotary tools'. For the record, I do not view Dremels with the awe and reverence of most Makers. Anyway, 5 minutes into the chat, dude showed me one of these. Let me muck about with it, but wouldn't sell it to me, the bastard. I was into the Goog as soon as I got home, placed my order 28 seconds later. You will *never* find a more needful Dremel accessory: The build quality is strong-like-bull and smooth-like-silk, there's add-ons available to make it even better, and it's just screamin' for a DIY CNC bodge. The manufacturer has a bunch of other products that seem equally lustworthy.

Music key display

Make 824
The latest Gadget Freak shows you how to make a music key display -

There was dissonance in the church when the pianist and other musicians had to hunt for the key their Music Leader was playing in. Dick's gadget took the guesswork out of the guitar, the meandering out of the mandolin and the pondering out of the piano. The Music Leader communicates the key to the others by setting the display on his Sending Unit via pushbutton or the foot switch, and the Remote Units replicate that display for everyone else. Now, they're all in one A chord (or F, or C, or...).
