Source Parts on TaoBao: An Insider’s Guide

Posted on by

For hardware aficionados and Makers, trips to Shenzhen’s Huaqiangbei have become something of a pilgrimage. While Huaqiangbei is a tremendous and still active resource, increasingly both Chinese and foreign hardware developers do their sourcing for components on TaoBao. The selection is vastly greater and with delivery times rarely over 48 hours and frequently under 24 hours for local purchases it fits in nicely with the high-speed pace of Shenzhen’s hardware ecosystem.

For overseas buyers, while the cost of Taobao is comparable to, or slightly less than AliExpress and Chinese online stores, the selection is again, many, many times the size. …read more

Safe Cracking is [Nate’s] Latest R&D Project

Posted on by

We love taking on new and awesome builds, but finding that second part (the “awesome”) of each project is usually the challenge. Looks like [Nathan Seidle] is making awesome the focus of the R&D push he’s driving at Sparkfun. They just put up this safe cracking project which includes a little gamification.

The origin story of the safe itself is excellent. [Nate’s] wife picked it up on Craig’s List cheap since the previous owner had forgotten the combination. We’ve seen enough reddit/imgur threads to not care at all what’s inside of it, but we’re all about cracking the code.

[Joe Grand’s] Toothbrush Plays Music That Doesn’t Suck

Posted on by

It’s not too exciting that [Joe Grand] has a toothbrush that plays music inside your head. That’s actually a trick that the manufacturer pulled off. It’s that [Joe] gave his toothbrush an SD card slot for music that doesn’t suck.

The victim donor hardware for this project is a toothbrush meant for kids called Tooth Tunes. They’ve been around for years, but unless you’re a kid (or a parent of one) you’ve never heard of them. That’s because they generally play the saccharine sounds of Hannah Montana and the Jonas Brothers which make adults choose cavities over dental health. However, …read more

The Think Tank at the Chicago Unconference

Posted on by

On Saturday the Hackaday community turned out in force to try something new. The first Hackaday Unconference was held in three places at the same time, and I was in Chicago and was amazed at the turnout and variety of presentations. The image above sums up the concept quite well, everyone shows up ready to give an eight minute talk, but as a whole, no one knows what to expect. Well, we should have known to expect awesome and that’s what we got.

As usual, people are excellent… to one another and in adapting to the fluid nature of the …read more

Your VR Doesn’t Stink (Yet)

Posted on by

What does it smell like when the wheels heat up on that Formula 1 car you drive at night and on the weekends? You have no idea because the Virtual Reality experience that lets you do so doesn’t come with a nasal component. Yet.

Shown here is an olfactory device that works with Oculus Rift and other head-mounted displays. The proof of concept is hte work of [Kazuki Hashimoto], [Yosuke Maruno], and [Takamichi Nakamoto] and was shown of at last year’s IEEE VR conference. It lets the wearer smell the oranges when approaching a tree in a virtual environment. In …read more

Toy Car Pumps the Wheels with Balloon Power

Posted on by

We’ve had our eye on [Greg Zumwalt]. He’s been working on some very clever 3D-printed mechanisms and his latest prototype is an air engine for a toy car. You can supply the air for the single cylinder with a compressor, or by blowing into it, but attaching an inflated balloon makes the system self-contained.

Last week we saw the prototype of the engine by itself, and wondered if this had enough power to drive a little train engine. We were almost right as here it is powering the front wheels of a little car.

This isn’t [Greg’s] first rodeo. He’s …read more
