Marvel fan re-creates the famous E.D.I.T.H. specs from Avengers and Spider-man using a Raspberry Pi Zero

by  •  • 0 Comments

Mike Darby, over at 314Reactor, has carried out an impressive make by re-creating the E.D.I.T.H. glasses from Spider-man Far From Home. If you haven’t seen Avengers: Endgame or Far From Home yet, stop reading and get thee to your nearest screen to check out these wonderful movies. I’ll leave a bit of a gap so that you don’t see anything you don’t want to!

E.D.I.T.H. (I’m not going to spoil the acronym!) is a set of glasses worn by Tony Stark in Avengers: Endgame and which are eventually given to Spider-man (played by Tom Holland). They carry an artificial intelligence which allows the wearer to control all sorts of Stark Tech and also see an enhanced version of the real world.

Mike Darby has taken a Raspberry Pi Zero, an Adafruit Powerboost, a LiPo battery, a camera and some other bits and pieces and re-created the glasses. The software uses Python and various libraries to do the text-to-speech and information look-ups, including a very nice tie-in to knowledge-provider Wolfram Alpha.

Sure, the glasses a bit bulkier than he would like and, because it’s a single-core Zero, it’s a bit slower than is ideal, but the concept is terrific. Kudos, especially, for the use of necessary Blutack to hold the glasses on his nose! You can find out more about the project by viewing the video below (which is, possibly intentionally, very funny, especially at the beginning, unless that’s just my sense of humour!) and by reading his blog.

New camera module targets A.I. algorithms and is compatible with the Raspberry Pi (and others)

by  •  • 4 Comments

China-based electronics manufacturer DFRobot has just launched a new Kickstarter to fund the HuskyLens, an A.I.-enhanced camera module. Built into the camera circuit is a Kendryte K210 chip, a 400MHz dual core RISC-V 64bit processor which facilitates the following algorithms:

  • Object tracking
  • Facial recognition
  • Object recognition
  • Line tracking
  • Colour recognition
  • Tag recognition

It should be popular with robotics people, especially, as a platform for solving tasks. It has the ability to detect spacial gestures, too, which means that your Minority Report-style interfaces or art projects are possible using the module.

The Kickstarter has a fairly punchy goal of over £18k, but hopefully it’ll get there (as I’ve just backed it myself!).

There are two flavours of camera – a standard, 2 megapixel module and an enhanced, 5 megapixel module for higher resolution pictures/videos.

One of the most intriguing features in on the back of the circuit – a 2-inch IPS screen. This means that you’ll be able to easily see what the camera module is doing while it is doing it without looking at another screen. The full specs are below:

You can get the Standard HuskyLens for about £20 or $20 at the moment with reasonable shipping costs. Costs go up after the first 200, so get in quick if you want one 🙂

The HuskyLens is compatible with the Raspberry Pi, Arduino, LattePanda and micro:bit.

LEGO Apollo Lunar Lander hooked up to a Raspberry Pi is a thing of beauty

by  •  • 0 Comments

Spotted this one in amongst all the 50th Anniversary celebrations of the Apollo Moon Landings.

Richard Hayler purchased the LEGO Lunar Lander set and built it up. He decided that he wanted a permanent enclosure to display it in and cut some perspex for the job. He then moved on to more hacky endeavours and decided to add lighting and button-controlled sound clips of the Apollo missions. The sound clips are played using a Pimoroni Speaker pHAT and some simple “Neopixel” strips were used to provide the illumination. He added three switches to control the lighting “moods” and three potentiometers (run through an MCP3008 analog-to-digital chip) to control RGB values. All the components were wired to a Raspberry Pi Zero:

The result is a very nicely-conceived project build with some simply-achieved, but very beautiful lighting effects:

Control a Raspberry Pi / CamJam EduKit 3: Robotics kit using two micro:bits

by  •  • 0 Comments

Young programmer Luke Spademan has built up a CamJam EduKit 3: Robotics kit and, after first of all using the excellent worksheets written by Tim Richardson, then converted it so that the Raspberry Pi inside the box can be controlled by a pair of micro:bits. You can read how he did it here and see the code on GitLab here.

I reckon there’s a way to control the Raspberry Pi over Bluetooth from the micro:bit, so I’ve asked Luke about it and will look further into it as I think this is an excellent control method using the accelerometer chip on the micro:bit to control direction.

Edit: Indeed, there is a way to control the Pi over Bluetooth. Barry Byford sent over this link which you could add to Luke’s work to just use a single micro:bit.

Comparison of SD card performance on a Raspberry Pi 4

by  •  • 0 Comments

Jeff Geerling has carried out a series of SD card benchmarks on his new Raspberry Pi 4 (1GB edition) and has shared them over on his blog. It is a great post, primarily because he doesn’t require the reader to read the whole thing before giving his results and recommendations.

For those in the UK, the Amazon UK links to the two he recommends are: the Samsung Evo Plus and the SanDisk Extreme.

pi-top launches number [4] on Kickstarter with a Raspberry Pi inside – check out the Earlybird offers quickly!

by  •  • 4 Comments

London-based pi-top have just launched the pi-top[4] on Kickstarter. Pitched as a ‘go anywhere’ computer, the [4] has the newly-released Raspberry Pi 4 (4GB version) built in. The key feature is the plastic case that surrounds the Pi and gives some buttons and a small OLED screen and onto it you can attach the ‘Foundation plate’ which allows you to expand the capabilities of the device.

The pi-top[4] pledges come in different flavours: the bare pi-top[4] “brick” (sorry, but it is a bit of a brick, a very high-functioning one, though!) itself, with an accompanying 11.6″ full HD screen (with touch capability) plus keyboard and with a robotics kit (the “AVK”). I won’t go into all the prices, but they’re about where they should be, thinking of their other products.

They appear to be making an effort to, once again, create their own “ecosystem”. This takes the form of the Foundation plate and their “component modules”. These vary from ultrasonic sensors to LEDs, potentiometers to light sensors. They seem to be all magnetic, so no soldering and easy-to-connect is the thing, here. They do, helpfully, provide a couple of male-to-male 40-pin headers so you can plug that into the GPIO pins, which are broken out to a female header on top of the case, and, presumably, use standard HATs with the Pi.

The screen, in particular, is very interesting as it provides a pi-topCEED-like desktop experience. The pity is that there is no screen-only option on the Kickstarter. I believe adding this would prove to be extremely popular, especially for those who already have a Pi 4 and are seeking to get a portable screen. They’ve done a very wise thing – you can just plug the pi-top[4] into the screen on the kickstand via the bespoke connector or you can plug in via an HDMI cable, allowing you to bring the Pi to the front of the screen for physical computing.

The robotics kit (AVK) looks very impressive – the pi-top[4] plugs into it using it’s bespoke connector and then you can build the robot in several different configurations.

Interestingly, they are pitching the pi-top[4] as being “portable” and, as such, it has an internal battery. This seems a bit strange as the Pi 4 is the most power-hungry of all the Raspberry Pis. Still, the Pi 4 being the newest, I can see why they went for it above a different model.

Overall, I think the pi-top[4] is an exciting product for the Pi community. I think it will find its place and, with the accessories that come with it, it’s clearly looking to build a flexible ecosystem. They have a modest $100k goal on Kickstarter, which I expect them to smash. Here’s hoping they allow people to buy the screen/keyboard on its own!
