For one reason or another, someone decided smartphones should have personalities. iPhones have Siri, Windows phones have Cortana, but these are just pieces of software, and not a physical representation of a personality. This may soon change with Sharp, with help from famous Japanese roboticist [Tomotaka Takahashi], releasing RoBoHoN, the first robotic smartphone.
RoBoHoN is by any measure a miniature humanoid robot; it can walk on two legs, it can wave its arms, and it can fit into excessively large pockets. This robot is also a phone, and inside its cold soulless chassis is a 2.0″ LCD, camera, pico projector to display movies and pictures on flat surfaces, and the electronics to turn this into a modern, mid-range smartphone.
In the video for RoBoHoN, this friendly little phone can do everything from hail a cab, add stuff to a shopping list, and be the life of the party. According to Akihabara News, Sharp should be releasing this tiny robot sometime in early 2016 but no word yet on price.

If you’re completely landlocked like I am, you may dream of ocean waves lapping at the shore, but you probably don’t think much about the tides. The movement of the ocean tides is actually quite important to many groups of people, from fishermen to surfers to coastal zone engineers. The behavior of the tides over time is helpful data for those who study world climate change.
Early tide prediction was based on observed changes in relation to the phases of the Moon. These days, tide-predicting is done quickly and with digital computers. But the first purpose-built machines were slow yet accurate analog computation devices that, as they were developed, could account for increasing numbers of tidal constituents, which represent the changes in the positions of tide-generating astronomical bodies. One of these calculating marvels even saved the Allies’ invasion of Normandy—or D-Day— in World War II.

We’d call it a robot, but [Eric Buijs] calls it a dolly. [Eric] bought a Makeblock starter robot kit last year, but never did anything with it. He recently wanted a camera dolly to help shoot project videos and the Makeblock hardware fit the bill.
[Eric] found that one of Makeblock’s example videos showed off a camera dolly but had no construction details. He cracked open the kit and got to work replicating what he had seen. Two 6V motors combined with a reduction gear, a belt, and some wheels, and the dolly now moves under computer control!

The first-ever Berlin Maker Faire was last weekend, and Hackaday was there. Berlin’s a city with an incredible creative vibe, so it’s no surprise that there was good stuff on display. What was surprising, though, was how far many of the presenters traveled to be there. I wandered around with a camera and a notebook, and here’s what we saw.

When [Bunnie] talks, we listen. He is a fount of product engineering knowledge, having seen many of his own products through from concept to market, and frequently helping others do the same. Of course having the knowledge is one thing, but he is also an accomplished speaker who knows what is important and how to share it in a way which is meaningful to others. The latest example of this is a pair of Engineering Talks he gave at Highway 1.
It’ll take you less than twenty minutes to get through the two videos. The first focuses on documentation for manufacturing. What do you need to include on a bill of materials sent to the factory? [Bunnie] has a set of gotchas which illustrate how vital this is. He also discusses how to handle design changes once the manufacturing wheels are already in motion. The second clip covers how Design for Manufacture relates to the actual cost of a production run. We hope there are more of these clips in the publishing pipeline so we’re keeping our eye on this channel.
The two videos are embedded below and at the time of writing had just a couple dozen views each and only one comment between the two of them. It seems sacrilege to say this, but we agree with that YouTube comment; these videos are gold.

It’s always nice to get down to the root directory of a device, especially if the device in question is one that you own. It’s no huge surprise that a Google product allows access to the root directory but the OnHub requires locating the hidden “developer mode” switch which [Maximus64] has done. The Google engineers have been sneaky with this button, locating it at the bottom of a threaded screw hole. Has anyone seen this implemented on other hardware before?
There isn’t a blog post regarding this, however [Maximus64] shared a video on YouTube walking us through the steps to root and un-root Google’s OnHub, which is embedded after the break. He also states “wiki coming soon” in the description of the video, so we’ll keep eye on it for an update.
We covered the product announcement back in August and have heard a few reviews/opinions about the device but not enough to make an opinionated assumption. Rooting the device doesn’t seem to increase the OnHub’s number of LAN ports but we think it’s still worth the effort.

A lot of digital processes are named after an old analog device that they’ve since replaced. It’s not uncommon to “tape” a show nowadays, for example, even though the recording work is actually done by a digital video recorder. Sometimes, though, the old analog devices have a certain je ne sais quoi that is desirable even in today’s digital world. This is certainly the case with [Dima]’s tape loop echo which is actually made with a physical tape loop.
The process of building the tape loop hardware is surprisingly non-technical. By positioning a recording head and a playback head right next to one another, a delay is introduced. An echo is created by mixing the original live sound signal with this delayed signal coming from the tape By varying the speed of the tape or altering several other variables, many different-sounding effects can be achieved.
Although in practice it’s not as simple as it sounds (the device required a lot of trial-and-error), the resulting effect is one that Pink Floyd or Beck would surely be proud of. Analog isn’t the only way to go though, there are plenty of digital effects that are easily created, and some with interesting mounting options as well.
