Lego Boosts Their Robotic Offering

January 21, 2017 by Al Williams 22 Comments

Kids often have their first exposure to robots in school using Lego Mindstorm kits. Now Lego is rolling out Boost — a robotic kit targeting all Lego builders from 7 years old and up. The kit is scheduled to be on the market later this year (it appeared at the recent CES) and will sell for about $160.

[The Brothers Brick] had a chance to try the kit out at CES (see the video below) and you might find their review interesting. The kit provides parts and instructions to build five different models: a cat, a robot, a guitar, a 3D printer, and a tracked vehicle. You can check out the official page, too.

CES2017: Astrophotography In The Eyepiece

January 9, 2017 by Brian Benchoff 27 Comments

If you’ve never set up a telescope in your back yard, you’ve never been truly disappointed. The Hubble can take some great shots of Saturn, nebulae, and other astronomical phenomena, but even an expensive backyard scope produces only smudges. To do astronomy properly, you’ll spend your time huddled over a camera and a computer, stacking images to produce something that almost lives up to your expectations.

At CES, Unistellar introduced a device designed to fit over the eyepiece of a telescope to do all of this for you.

According to the guys at Unistellar, this box contains a small Linux computer, camera, GPS, and an LCD. Once the telescope is set up, the module takes a few pictures of the telescope’s field of view, stacks the images, and overlays the result in the eyepiece. Think of this as ‘live’ astrophotography.

In addition to making Jupiter look less like a Great Red Smudge, the Unistellar module adds augmented reality; it knows where the telescope is pointing and will add a label if you’re looking at any astronomical objects of note.

While I wasn’t able to take a look inside this extremely cool device, the Unistellar guys said they’ll be launching a crowdfunding campaign in the near future.

CES17: Arduino Unveils LoRa Modules For The Internet Of Things

January 6, 2017 by Brian Benchoff 34 Comments

WiFi and Bluetooth were never meant to be the radios used by a billion Internet of Things hats, umbrellas, irrigation systems, or any other device that makes a worldwide network of things interesting. The best radio for IoT is something lightweight which operates in the sub-Gigahertz range, doesn’t need a lot of bandwidth, and doesn’t suck down the power like WiFi. For the last few years, a new low-power wireless communication standard has been coming on the scene, and now this protocol — LoRa — will soon be available in an Arduino form factor.

The Primo, and NRF

It’s not LoRa, but the Arduino Primo line is based on the ESP8266 WiFi chip and a Nordic nRF52832 for Bluetooth. The Primo comes in the ever-familiar Arduino form factor, but it isn’t meant to be an ‘Internet of Things’ device. Instead, it’s a microcontroller for devices that need to be on the Internet.

Also on display at CES this year is the Primo Core which we first saw at BAMF back in May. It’s a board barely larger than a US quarter that has a few tricks up its sleeve. The Primo Core is built around the nRF52832, and adds humidity, temperature, 3-axis magnetometer and a 3-axis accelerometer to a square inch of fiberglass.

The Primo Core has a few mechanical tricks up its sleeve. Those castellated pins around the circumference can be soldered to the Alice Pad, a breakout board that adds a USB port and LiPo battery charger.

LoRa

Also on deck at the Arduino suite were two LoRa shields. In collobration with Semtech, Arduino will be releasing the pair of LoRa shields later this year. The first, the Node Shield, is about as simple as it can get — it’s simply a shield with a LoRa radio and a few connectors. The second, the Gateway Shield, does what it says on the tin: it’s designed to be a gateway from other Arduino devices (Ethernet or WiFi, for example) to a Node shield. The boards weren’t completely populated, but from what I could see, the Gateway shield is significantly more capable with support for a GPS chipset and antenna.

A partnership with Cayenne and MyDevices

Of course, the Internet of Things is worthless if you can’t manage it easily. Arduino has struck up a partnership with MyDevices to turn a bunch of low-bandwidth radio and serial connections into something easy to use. Already, we’ve seen a few builds and projects using MyDevices, but the demos I was shown were extremely easy to understand, even if there were far too many devices in the room.

All of this is great news if you’re working on the next great Internet of Things thing. The Primo Core is one of the smallest wireless microcontroller devices I’ve seen, and the addition of LoRa Arduino shields means we may actually see useful low-bandwidth networks in the very near future.

Hackaday Links: The 2017 One

January 1, 2017 by Brian Benchoff 21 Comments

You screwed everything up last night. The end of 2016 had a leap second, so instead of the seconds going up from 57, 58, 59… 00, there was a 61st second in the last minute of the year. Yeah, 2016 just wouldn’t quit. [Michel] built a device to keep track of 2016’s leap second using GPS, and everything worked beautifully.

Remember MechWarrior? There’s a reason those mid-90s games used mechs instead of more organic characters. Computers couldn’t draw that many polygons, making MechWarrior a stylistic choice driven by the limitations of technology. Here’s a real MechWarrior that could rip your head off without trying.

The Hackaday Retro Edition is a Web 1.0 version of our main blog, and a challenge to retrocomputing enthusiasts. [PK] recently got his Psion Series 3a surfing the interwebs with a little help from PPP and a Raspberry Pi. He also got a Psion Series 7 online using the same method, but that was a little more anti-climatic.

The NES Classic Edition costs too much, the cords are too short, and you can’t play anything but the pre-installed games. There’s a solution to this: [Andrew] has been working on the Beagle Entertainment System for a while now, and it’s ready for a proper release. The BES uses the SNES9X, VBA-M, and Nestopia emulators, with the original ROMs, and has a ‘shield’ for SNES gamepads. You can’t do better than this, and it’s cheaper than the NES Classic Edition.

Vacuum pens, or vacuum pickup tools, or whatever you want to call them, are really useful when working with SMD parts. You can build your own out of an aquarium pump, duct tape, a lighter, paperclip, and a mechanical pencil, but that lacks the elegance of a footswitch-operated, solenoid valve pickup tool. [Dave] built a great version of a vacuum pickup tool from scratch for less than $200. There’s NTP fittings on here, so you know it has to be great.

Terrible news! I’m in Vegas next week for CES. While I’ll be spending most of my time figuring out ‘which internet of things is best internet of things’, I might have some time for a Hackaday CES meetup.

The best idea I have for a Hackaday CES meetup is the Fun Dungeon in the Trashy Castle. It has Skee Ball and Crazy Taxi. If you have a better idea of where Hackaday fans and aficionados can meet up for an hour or two, leave a note in the comments below.

Hackaday Links: January 10, 2016

Everybody loves cheap stuff, and we hate telling everyone about coupon codes. That said, TI has a new LaunchPad development board they’re promoting. It’s based on the MSP432, the ARM extension of their MSP430 line. The MSP432 is an ARM Cortex M4F, low power, and planned for production later this year.

Here’s your daily CES garbage post. Through a collaboration between Sony and Nissan, a car has become a video game controller controller. A controller plugs into the ODB II port, reads throttle, brake, and steering wheel positions (and buttons on the dash/steering wheel, I guess), and translates that into controller input for a PlayStation 4. What games do they play with a car? You would think Gran Turismo, Rocket League, or other games with cars in them. Nope. Football.

Dangerous Prototypes is a legal Chinese company! [Ian] didn’t say anything about the process about becoming a legal Chinese company because he wrote a blog post, not a book. Shenzhen Dangerous Prototypes Electronics Technology Limited allows them to have an office in the Shenzhen electronics market, hire local and foreign hackers, host Hacker Camp Shenzhen, and allow people to apply for ‘Authorized Authority’ visa letters for the people who need them. Great news for a great company.

The Forge hackerspace in Greensboro, NC is growing. In just over a year they have 160 members and they’ve already outgrown their 3,400 square foot space. Now they’re moving to a larger space that’s twice the size and they’re looking for donations.

People have been taking old iPad screens and turning them into HDMI displays for years now. [Dave] got his mitts on a panel from a Macbook Pro 17″, and turned it into a monitor. It required a $50 LVDS adapter, but the end result is great – a 1920×1200 panel that looks pretty good.

The 3D Printers Of CES

January 6, 2016 by Brian Benchoff 65 Comments

CES, the Consumer Electronics Show, is in full swing. That means the Hackaday tip line is filled to the brim with uninteresting press releases, and notices that companies from the world over will be at CES.

3D printing has fallen off the radar of people who worship shiny new gadgets of late, and this is simply a function of 3D printing falling into the trough of disillusionment. The hype train of 3D printing is stuck on a siding, people are bored, but this is the time that will shape what 3D printing will become for the next ten years. What fascinating news from the 3D printing industry comes to us from CES?

Sigzig Data Loggers Ditch The Noise While Pimping The Case

January 21, 2015 by Mike Szczys 25 Comments

We ran into [Paul Allen] at CES. He was showing off Sigzig, a super-low noise data logger which his company is just rolling out.

A couple of years ago he worked on a standalone chemical sensor and had a few extra boards sitting around after the project was done. As any resourceful hacker will do, he reached for them as the closest and easiest solution when needing to log data as a quick test. It wasn’t for quite some time that he went back to try out commercially available loggers and found a problem in doing so.

The performance of off-the-shelf data loggers wasn’t doing it for [Paul’s] team. They kept having issues with the noise level found in the samples. Since he had been patching into the chemical sensor PCBs and getting better results, the impetus for a new product appeared.

The flagship 24-bit 8-channel Sigzig samples 0-5v with less than 1uV of noise. A less expensive 4-channel differential unit offers 18-bit with 10-12 uV of noise. They are targeting $199 and $399 price points for the two units. We asked about the sample rate in the video below. The smaller version shown here captures up to 240 samples per second. The big guy has the hardware potential to sample 30,000 times per second but ~~since the data is continuously streaming over USB~~ that rate is currently limited to much less.

Update: It has been pointed out in the comments that USB may not be the choke point for sample rate.
