Raspberry Shake – your personal seismograph

via Raspberry Pi

There are some applications for the Raspberry Pi that were a very long way from our minds back in 2009, when we were trying to come up with a computer to get kids programming again. I think it’s fair to say that we did not think we were building a personal seismograph.

Raspberry Shake has blown past its Kickstarter target of $7,000 to raise ten times that amount, and it’s still got a couple of days to go.

Raspberry Shake is sensitive enough to detect earthquakes of magnitude 2 and higher at a distance of 50 miles, and earthquakes of magnitude 4 or greater from 300 miles away. Angel Rodriguez, the maker, says:

It will also record earthquakes of larger magnitudes farther away but it will miss some of the subtleties. Raspberry Shake can detect and record short period (0.5 – 15 Hz) earthquakes; the farther away an earthquake, the less of that range of frequencies can be recorded.

At the heart of this kit is a geophone: a device that converts movement into voltage. (Think of it as being a bit like a microphone for geology.) Inside the little geophone a coil moves relative to a magnet, creating current. Angel has a nice demonstration of how a geophone works:

What’s inside a Geophone

In order to get data coming from the ground we need a sensor able to detect these data. A geophone is a ground motion transducer that convert ground movement into voltage. Raspberry Shake use a geophone and in this video we are going to show you what’s inside of it.

The little add-on board amplifies and digitises the signal from the geophone, and feeds it to your Raspberry Pi.

The Raspberry Pi time-stamps the data and stores it in a seismic industry standard format and sends it in answer to client requests. Those requests are displayed on your smartphone or computer monitor. The complete system is called a seismograph.

Angel and the other instrument builders behind the Raspberry Shake make seismographs and other equipment for a living. This device is the little brother of a seismograph his team makes for universities and other earthquake observers. It runs the same open-source software that the United States Geological Survey (USGS) uses.

Angel says:

Don’t be fooled by the size and the price. Raspberry Shake is better than many of short-period seismometers in current use by the local networks of the USGS and many developing countries. Several software vendors have, for the first time, provided personal no-cost licenses for this project.

Raspberry Shake will make observatory quality data that can be shared in the worldwide standard SEED format. All modern automated seismology programs used by observatories can use the data from the Raspberry Shake. It’s the Volkswagen of seismometers – yes there are Lamborgini seismographs but both the Lamborghini and the Volkswagen will get you from point A to point B.

To prove it, here’s some data from a Raspberry Shake ($99 if you back the Kickstarter now) against data from a $50,000 professional seismograph. In this image the Raspberry Shake’s data is displayed at the top. Both devices are showing data from the same regional earthquake.

Bringing the affordability of a piece of kit like this down to consumer levels is a real achievement: previously this sort of equipment has only been available to universities, governments and other bodies with the ability to make very big investments. As you’ve probably gathered, we love it: head over to back Raspberry Shake on Kickstarter quickly, before the opportunity’s gone!

ZeroBorg: teeny tiny robotics from PiBorg

via Raspberry Pi

Raspberry Pi robotics aces PiBorg are known for quality robots and add-ons, from the tiny PicoBorg board to the somewhat terrifying DoodleBorg. Now they’re bringing their magic to the Raspberry Pi Zero with ZeroBorg, a small but powerful motor controller and sensor board. We weren’t surprised to see their Kickstarter campaign hit its target quickly; there’s still time to jump on board.

ZeroBorg robot

ZeroBorg costs from £15 and is barely larger than a Raspberry Pi Zero, and a Zero + ZeroBorg + 9V battery weigh as little as 65g, but it doesn’t pull its punches. You can control four motors independently, or more if you stack multiple ZeroBorgs over I2C (ideal for animatronics projects or CNC machine servos); I2C communication also means you can connect it to other add-on boards to pile on extra functionality, and there are two analogue inputs so you can connect any sensors that your project demands. It’s available with an infrared module, so you can control it via a TV remote, and a DCDC regulator for powering the Pi Zero. And, as with PiBorg’s other boards, they will provide open source software for controlling the board, so you can set up your robot exactly the way you choose.

ZeroBorg

PiBorg told us,

We love making boards and kits for the Raspberry Pi, mainly because the Pi community is like one big growing family. The support we’ve received so far with this Kickstarter has been phenomenal and we can’t thank the community and the Raspberry Pi Foundation enough.

Many people are learning about programming, electronics and robotics with the Pi. Every day a new Pi project appears, and the community jumps in and helps develop ideas and solve problems.

Already there are really awesome projects such as a Zero that makes tea in the morning, and a robot that feeds your cat while you are away. We can’t wait to see what people build with the ZeroBorg!

Neither can we. Take a look!

Fail of the Week: OpenMV Kickstarter Project Hits Manufacturing Snag

via Hackaday » hardware

Making stuff is hard, especially when you are making lots of stuff. The OpenMV Cam project knows this, because it has hit a problem while putting together their cheap machine vision module. The problem is with the BGA solder balls that connect the image sensor to the main board.

openmv-thumbWe’ve covered this intriguing project before: the aim is to build a small, cheap module that can run image processing algorithms to easily give robots sight. The sensor is a Ball Grid Array (BGA) package, which means there are a grid of small solder balls on the back that form the electrical connections. It seems that some of these solder balls are oxidized, preventing them from melting and fusing properly with the board. This is called a head-in-pillow defect, because the ball behaves like your head when you lie down in bed. Your head squishes the pillow, but doesn’t merge into it. There are 38 balls on the OV26040 image sensor and even a single bad link means a failure.

The makers of the project have tried a number of solutions, but it seems that they may have to remake the ball links on the back of each sensor. That’s an expensive process: they say it will cost $7 for each, more than the actual sensor cost initially.

A few people have been posting suggestions in the comments for the project, including using solvents and changing the way the sensors are processed before mounting. We’d like to see them overcome this hurdle. Anybody have any suggestions to quickly and cost effectively move the manufacturing process forward?

Thanks to [eDgE] for the tip.

Meet my Pixel Pals from Soldering Sunday

via Raspberry Pi

I’m always on the lookout for fun physical computing gadgets to teach young people basic electronics, soldering skills, and of course how to code. If they work with a Raspberry Pi then I get even more excited. Some time last year I happened across a Kickstarter campaign that ticked all my STEAM boxes from a small company called Soldering Sunday established by a group of adventurous makers from Monroe, New Jersey, USA. Their campaign was called CHIP – an electronics kit with character and immediately grabbed my attention. Thankfully I was not alone and the campaign was successfully kickstarted.

Thanks to @solderingsunday for my #chip kit. I upgraded his leds to multi colour!

A video posted by Miss Philbin (@missphilbin) on

Chip is part of a group of ‘Pixel Pals’ designed to grab the attention of young makers, encouraging them to explore new skills and to play with technology in a new way. He consists of a circuit board, two LEDs, two resistors and some connecting pins. I had to build him myself before connecting him to the Raspberry Pi GPIO pins and programming his eyes with Python. I enjoyed the activity so much that Chip now accompanies me everywhere.

In fact, he has made many a long trip. He appeared in Australia for PyCon as part of my Physical Computing talk to teachers and has even featured in the background of a BBC Technobabble episode back home in Cambridge! I’ve been worrying that during my travels, Chip might be getting a little lonely. Lucky for me then that Soldering Sunday have launched their latest Pixel Pal, called Buzz!

Buzz – A New Pixel Pal

Soldering Sunday is raising funds for Buzz – A New Pixel Pal on Kickstarter! Buzz is an easy and fun educational kit that builds STEAM / STEM skills and grows from a project to a friend you can program.

The latest Pixel Pal kit includes a Buzz kit (like Chip but with a buzzer), a Pixel Power Kit, and a Pixel Pal Pi adapter kit. Its creators say:

When you plug Buzz into a Raspberry Pi or an Arduino, you can control his eyes and his sounds with programming. Buzz is an excellent way to get kids involved in Computer Science and take part in the Hour of Code initiative. We already have Arduino and Raspberry Pi tutorials online for Chip and with your support we will have the Buzz tutorials available shortly.

Please help to support the Buzz Kickstarter campaign so that I have more toys to play with. You won’t be disappointed!
