Add Intuitiveness to OpenSCAD With Encoders

The first time I saw 3D modeling and 3D printing used practically was at a hack day event. We printed simple plastic struts to hold a couple of spring-loaded wires apart. Nothing revolutionary as far as parts go but it was the moment I realized the value of a printer.

Since then, I have used OpenSCAD because that is what I saw the first time but the intuitiveness of other programs led me to develop the OpenVectorKB which allowed the ubiquitous vectors in OpenSCAD to be changed at will while keeping the parametric qualities of the program, and even leveraging them.

All three values in a vector, X, Y, and Z, are modified by twisting encoder knobs. The device acts as a keyboard to

  1. select the relevant value
  2. replace it with an updated value
  3. refresh the display
  4. move the cursor back to the starting point

There is no software to install and it runs off a Teensy-LC so reprogramming it for other programs is possible in any program where rotary encoders may be useful. Additional modes include a mouse, arrow keys, Audacity editing controls, and VLC time searching.

Here’s an article in favor of OpenSCAD and here’s one against it. This article does a good job of explaining OpenSCAD.

[Editor’s note: This is a Hackaday writer’s hack, hence the “I” in place of the usual “we”. We all love custom peripherals though, and a good number of us love OpenSCAD, so you could probably read it either way, but we don’t want to take credit for [Brian]’s work.]

Phone Booth becomes a Photo Booth

A project by Chris Bell, Liangjie Xia, and Mike Kelberman called Rotobooth is a hacked rotary phone that takes your picture as you’re calling your own cell phone, then sends a link of the photos to you by SMS.

The rotary phone was hacked using Arduino, the photos were collected on a Flickr page, and finally the SMS notification is sent using Twilio. The exterior design is clean (dig the orange phone!) and recently took 3rd place at Twilio’s Photohack Day 2.

Tweephone is a rotary phone Twitter client, even your grandma could love

The collectives behind the Tweephone, UP digital Bureau and Unteleported tech agency, claim that it's the first analog Twitter client. We find that hard to believe but, while we've seen rotary phone-based Twitter tools before and analog meters that measure microblogging activity, we couldn't come up with a single example of a client that lets you punch in messages through non-digital means. Even if it's not the first of its kind, the Tweephone is still a pretty neat hack. Inside the old-school chassis is the ubiquitous Arduino, which interprets your pulls of the dial as letters. Like a phone with only a dial pad, you'll have to ring up numbers multiple times to get the right letter (i.e. dial "2" three times to get a "c"). It definitely not the most efficient method for sending out 140-character missives, but certainly one of the more unique. Check out the video after the break to see it in action.
