iFixit: Welcome to Repair 2.0

This interesting video — really a commercial for iFixit — has some fascinating things to say that would resonate with makers. Do you see yourself slaving over some 386 trying to get it to work? If iFixit creates a Wikipedia-like repair guide, will you contribute? Leave a comment with your thoughts. [Via bunnie’s blog] More: […]

Hollow spy bolts

Hollow spy bolts

Brian Dereu of Hollow Spy Coins showed us how to make this hollow dead-drop bolt for stashing secret messages back in MAKE 16. It’s not hard to do if you have access to the necessary equipment–a drill press, hacksaw, vise, grinder, and the appropriate taps and dies. But if you don’t have those tools, or you don’t have the time to use them, and you still want a spy bolt, Brian will gladly sell you one hand-made by his family and him for the not-unreasonable price of $37.

Bulbdial clock has no moving parts, casts shadows for hands

Bulbdial clock has no moving parts, casts shadows for hands

This clever clock kit from EMSL has an analog-style face, but no hands. Instead, kinda like a sundial, it has a “gnomon” that sticks up in the middle. Three rings of inward-pointing LEDs are positioned around the rim, each a different color and each at a different angle relative to the face. The blue ring is at the shallowest angle, and thus casts the longest shadow representing the “seconds” hand. The red ring is at the steepest angle and casts the shortest shadow to make the “hours” hand. The green ring, in the middle, is minutes. Check the video above, courtesy YouTube user amandachou, to see it in action.

The “Bulbdial” clock is available as a kit with four different case options, but the clear/black variety shown above is definitely my favorite because it shows off the cool retro-futurist logo on the circuit board. Here’s a time-lapse video of YouTuber jcorsaro building one from a kit.
