Raspberry Pi launches new all-in-one Pi 400

Raspberry Pi has just announced the launch of the Pi 400. This is, essentially, a Raspberry Pi 4 inside an official Raspberry Pi keyboard.

TL;DR – it’s really nice and will certainly be a solution to “I just want to use a Pi as a desktop machine!”.

Get on from The Pi Hut or Pimoroni.

Away from the basics, it actually contains a redesigned Pi 4 board that is much larger than normal, but also much shorter than the regular board. It contains an updated Broadcom 2711 processor that will run at 1800MHz and breaks out all the ports to the back of the keyboard. You can see the insides of the keyboard here (thanks to Jeff Geerling for this photo):

I was lucky enough to get access to a Pi 4 unit a week or so ago. It’s extremely well-built – the moulding is of the highest-quality – with no creaking even when twisted. It feels very solid (thanks to the very large heatsink plate stuck to the processor) and, actually, quite “expensive”.

The Pi 400 is available on its own at $70 (or your local equivalent) or at $100 with all the gubbins you need to get going, such as the official power supply, cables and a copy of the Official Raspberry Pi Beginners book. There are also local variations of keyboard that will be available soon.

Other non-UK resellers can be found from the Resellers page on the Raspberry Pi website.

Thanks to The Pi Hut for the full kit image!

Vizy, the Raspberry Pi-powered AI camera with lots of options – crowdfunding on Kickstarter now!

Charmed Labs, the team behind the well-known Pixy camera, have launched a new Kickstarter campaign for “the Vizy”. The Vizy, which is powered by a Raspberry Pi 4 (of various memory sizes), takes photographs with a 12 megapixel camera and then internally processes the images to determine what is in them. If it detects a certain animal, or even something else, it can then be programmed to take specific actions. For example, if it spots a squirrel, it might activate an automatic feeder specifically for that animal. Another example: you might want to measure how many cars or vans pass your house every day – the Vizy will help you do that.

They have developed a software stack to handle all this and you can see a sample on this page, although full documentation on the software is yet to be completed. The Vizy will come with a suite of ready-made applications that can be used as they are, or with modifications. One of them, the Birdfeeder app, recognises 20 common bird species and then, once identified, uploads photographs to the cloud.

To go with the 12 megapixel camera, which uses the same Sony sensor as the official Raspberry Pi HQ Camera, they have improved the software to allow capture of high quality video up to 300 frames per second.

As well as the software, a special I/O interface on the side of the Vizy lets you add additional peripherals to control hardware devices.

All-in-all, it’s a very nice piece of kit, and is a step-up from something like the NatureBytes camera in terms of the software and the design of the product.

The Vizy costs from $229 (on the Earlybird for the 2GB Pi 4 version) and then rises accordingly.

Programmable Bluetooth remote for the Raspberry Pi comes to Kickstarter

A company called Remodo based in Honk Kong have developed a flexible remote control that works over Bluetooth and IR/HID to control functions on your Raspberry Pi and has created a Kickstarter campaign to fund it. Designed for home automation, smart living and home entertainment, the Remodo X is pretty stylish and comes with an app for your mobile to configure the functions. A GitHub library to support various home automation projects has already been started and will be available soon. The Remodo X is on Kickstarter for around £30 in HK$.

New version of the micro:bit launched – but won’t be available until November

Great news from the micro:bit Foundation today. There will soon be a new version of the micro:bit available to buy!

There are several exciting new features on the version 2:

  • An integrated speaker
  • An integrated MEMS-type microphone
  • A new capacitive touch button built into the main logo on the front
  • A new sleep mode to enable low power consumption when not in use
  • A new processor (nRF52833)
  • The flash memory has been doubled to 512kb
  • The RAM has been increased to 512kb (an 8x improvement!)
  • The ability for add-on boards to draw up to 200mA current
  • A new “notched” edge connector to allow crocodile clips to connect more securely.

There will be some minor compatiblity issues – the increase in components on the back will mean that some of the existing cases will not fit and the LED column pins on the edge have been swapped around (although very few add-ons use these).

This is a really exciting development from the Foundation – it’s great to see them investing the time and resources in a new version and it’s sure to give a boost to not only the buying market but, more importantly, the chance for creative activities.

Interestingly, they have chosen to announce the new version in advance of availability. This presents two issues that I can see: 1) No-one will want the existing stocks of version 1 and 2) The publicity they receive from announcing it early will be somewhat wasted by the delay. However, it also means that consumers will be happier as they may decide to hold off until the new version is available.

You can read a more in-depth article about the version 2 over at micromag and also at Tom’s Hardware where Les Pounder also covers the release. Pimoroni will have the new version and have an email list so you can get notified when it’s available. This is addition to regular suppliers Farnell and new partner OKdo.

Carnegie Mellon student retrofits a Polaroid camera with a Raspberry Pi, camera module and thermal printer

Sam Zeloof, who is currently studying electrical engineering at Carnegie Mellon University as an undergraduate has taken an old Polaroid camera and retro-fitted it with a Raspberry Pi W, a camera module and a thermal printer. He added two LiPo batteries to provide the 7-8 volts needed by the printer and then programmed the whole thing to produce thermally-printed photographs whenever the trigger was pressed. You can read all about the project and how he did it over at IEEE Spectrum.

Intrusion detector lights up and counts using a Raspberry Pi

Nick decided that he wanted a more visual representation of the attempts bots made to attack and gain access to his server. To do this, he took a Raspberry Pi Zero W, a Pimoroni Blinkt and a 7-segment display and created a device called the PiAlert, the case of which was 3D-printed. For the software, he configured fail2ban (which monitors log files) to trigger a special action whenever it detected a potential intrusion. The triggered action is a Python3 script (which Nick admits is an absolute mess!) which acts as an HTTP server, listening for the notifications from fail2ban and lighting up LEDs accordingly. The 7-segment display is also updated to show the number of intrusion attempts made.

You can read more about the device on Nick’s blog, including how to do it yourself..

Here is a video of the PiAlert in action:
