IPhone 4 Steadicam

July 20, 2010 by Jakob Griffith 25 Comments

It’s been a while since we’ve seen a steadicam, and to quench our thirst is this iPhone 4 steadicam. The system does use the typical 3 axis PVC gimbal and heavy weight setup that we’ve seen before, but (why has it taken so long to get this implemented?) the addition of a hand grip means you no longer get blistered fingers. The tutorial recommends the use of an expensive cup holder mounting system, but we think making your own epoxy one might save another dime and allow a wider range of cameras or phones.

The whole process is also wrapped up in a quick and simple how-to video (after the jump alongside an in action video), which goes to show even though a hack may have been done several times before, presentation can make a big difference and impact.

Three Pendulum Harmonograph

Just the other day we were thinking “You know what we need more of around here? Harmonographs!” And our requests were answered when [Paul] sent in his three pendulum harmonograph. For those unaware, it’s a mechanical device that draws Lissajous curves or “really cool circles” to quote some of our staff.

[Paul] includes all the plans necessary to make your own harmonograph and begin drawing today. If you can’t wait, there’s a video of the three pendulum harmonograph etching a masterpiece after the jump. Continue reading “Three Pendulum Harmonograph” →

DIY Coffee Table Scale

[Guus] screwed together this coffee table which doubles as a scale. No welding was required to put it together – just some bolts, pulleys, miscellaneous fittings, and an original design. The weight is indicated through the (unlabeled) position of the counterweight arm. Currently it is limited to measuring 10kg (22 pounds), but can easily be boosted by adding a heavier counterweight. It looks pretty robust, maintenance-free, and fitting for any living room workshop’s weighing needs. [Guus] is also the proud inventor of the rock radio, and he is working on creating Man-Y-Man: a modular play system allowing children to create up to 1520 unique creatures.

Logging Weight Changes

This is a classic example of a well done hack, simply for the sake of hacking. [Jorge] wanted to be able to chart his weight changes. His solution wasn’t to simply buy a scale that could be hooked to the computer. Those are available and aren’t really that expensive. He could have even used pencil and paper to chart it in a few seconds. Instead, [Jorge] started hacking. He took apart a digital scale he already had and installed his own circuit to display weight and write the values to a CSV. The CSV resides on a removable card which can then be put in his computer to chart the data in openoffice.
