Picade Console DIY kit (Picade console)

 

Power-up your TV with Picade Console! It's a compact, Raspberry Pi-powered retro games machine with authentic arcade controls that plugs right into your TV, monitor, or other HDMI display.

Picade Console is fight stick-style arcade console that riffs off our new Picade with the same retro feel, same joystick and buttons, dedicated power button, and driven by the same powerful combo of the Raspberry Pi and Picade X HAT. It's beautifully packaged, comes with stickers and a neon-infused A3 Picade Console poster, and full assembly instructions.

It comes in kit form and takes an hour or two to build. The enclosure is made from powder-coated MDF and acrylic, giving it an authentic arcade look and feel. All you'll need to add is a Raspberry Pi, power supply, HDMI cable, and micro-SD card.

*TV not included! Using a CRT TV requires additional adaptors.

Features

  • Black, powder-coated panels
  • Acrylic console with retro artwork
  • Push-fit arcade buttons
  • Joystick with black ball top
  • Speaker (3W, 4Ω, 2.5" driver)
  • Easy access with removable back panel
  • Dedicated illuminated power button
  • Grippy rubber feet
  • Dimensions (assembled): 245x120x140mm

 

Picade X HAT features

  • Easy DuPont connectors for buttons and joystick
  • Push-fit speaker terminals
  • I2S audio DAC with 3W amplifier (mono)
  • Power management, power switch pins, and power button
  • 4-way joystick inputs
  • 6 player buttons
  • 4 utility buttons
  • Metal standoffs to hold your Picade X HAT securely

 

Extras

  • Picade Console poster / assembly instructions
  • Picade stickers

 

What's new?

Picade Console is more compact and easier to build, but has a bunch of new features liked a dedicated power button, better cable routing out the back of the console with a panel-mount micro-USB connector for power, and slick new artwork.

The new buttons in Picade are lower profile, and the new joystick has a single connector rather than the eight spade connectors on our previous Picade joystick.

Picade X HAT is all-new and packed full of useful features. We've moved from more fiddly screw terminals to simple DuPont connectors that just push in, and the speaker terminals are the same easy push-fit connectors that we use on pHAT BEAT.

There's dedicated power management on-board Picade X HAT; just plug your micro-USB power supply into the HAT and it'll power your Pi through its pins. The power button connected to the HAT means that once your Pi is safely shutdown, the power will be cut completely to the Pi. A simple press of the power button will boot your Picade Console up again.

Software setup

We recommend the RetroPie operating system for your Picade. You can download it from the RetroPie website and then burn it to a micro-SD card with Imager.

Connect a USB keyboard to your Pi, and connect to Wi-Fi in the RetroPie menu. Press F4 to exit to the terminal and then type curl https://get.pimoroni.com/picadehat | bash to run the Picade HAT installer.

Reboot your Pi, if it doesn't prompt you to. Press the "Alt" key on your keyboard and then select "Configure input" to configure your Picade Console's controls. You'll find that the sound and power button should both be working now too!

Cambridge University Press - Black Flag: A Coding Club Mission (book black flag)
Description:

Welcome to Black Flag: A Coding Club Mission

In Marshall Trent’s Reunited Kingdom every citizen of New Edgehill has a neurochip implanted within them that links directly to the Neuralnet.

The Neuralnet sees and records every thought, movement and microscopic detail of every life in New Edgehill. Absolute control!

Cal Jones believes he is no different from everyone else. That is until he saves the life of Sasha and learns that everything that he thought was true is in fact a lie. He discovers an underground group, the Anarchists, living outside of the Neuralnet and harbouring a secret which will change his life forever.


Read the Book

Matt Langley has written a fantastic, imaginative and exciting novel for the Coding Club series. You can even read the first Chapter now: http://codingclub.co.uk/uploaded_pdfs/BlackFlag_sample.pdf

More info at http://codingclub.co.uk/black_flag.php
Join Danni as you train as an Anarchist


This is a Coding Club mission. This means that you can get far more involved in this book than any other you have read before – should you wish to. To register for free, all you need to do is enter an activation code and fill in a short form. Unfortunately we cannot just leave activation codes in plain view. You will have to visit the Black Flag website and think like a true hacker – ignore the visuals and dig into the code!

I will guide you throughout your training as an Anarchist agent. You will solve many of the assignments that Cal, Sasha and I face in our struggle. Do not worry if you are still a novice programmer, there is lots of guidance and hints along the way.

All the preparation that is necessary is that you have worked through Coding Club: Python Basics. Alternatively you should be fine if you have learnt a little Python 3 some other way. You simply need to have a grasp of how to write variables and functions, perform simple maths operations and manipulate strings. You should also know how to save and load files in IDLE.

It is not going to be easy, but trying to save the World never is!

Adafruit PiTFT Plus 320x240 2.8" TFT Capacitive Touchscreen(40 pin) (2.8 display touch cap 40pin)
Description:

Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x240 16-bit color pixels and a capacitive touch overlay. That's right, instead of a resistive touchscreen, which requires a fingernail or stylus, you can now use a fingerpad.

The screen looks much nicer, with a black bezel and glass overlay.

This updated design fits perfectly onto the Pi Zero, Pi 3, Pi 2 or Model A , B ! (Any Pi with a 2x20 connector) Not for use with an old Pi 1 with 2x13 connector. This version also has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath.

The display and touchscreen uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. All other GPIO are unused and you can still share the I2C pins with sensors, LED drivers, etc. Since we had a tiny bit of space, there's 4 slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.

Use it for console access or easily pop up X11 onto the PiTFT for a mini monitor, although its rather small at 320x240. Instead, we recommend using PyGame or other SDL-drawing programs to write onto the frame buffer.

Raspberry Pi computer and enclosure not included! As of July 22nd, 2015 this display comes fully assembled with tactile switches too

PUD Board (Pull-Up/Down Resistor Board) (MMP PUD board)

RASPBERRY PI BOARD NOT INCLUDED

Description:

Whether you're pulling-up or pulling-down, there's no need to frown! With the PUD board from ModMyPi, adding multiple pull-up or pull-down resistors to your Raspberry Pi project is easy!

If you want to detect an "output" with your Raspberry Pi, like a button being pressed or a motion sensor detecting movement, we can configure our Raspberry Pi's GPIO pin as an "input". That input pin can be in three states (known as Tri-State logic); "high", when 3.3V is applied, "low", when the pin is connected to 0V, and "floating" when the state is undefined. Floating voltages are troublesome in electronics as the input can either read high or low depending on various fluctuations in electrical noise. Like a gate flapping open and closed in the wind, someone needs to lock the gate closed, or wedge it open. If you leave it flapping, it's likely to hit someone on their bottom on the way through!

Like our gate, the best way to avoid a floating input is to "tie" your input pin either high or low to create a default state. This is usually achieved through the use of a pull-up or pull-down resistor, either connecting our input pin via a resistor to the Pi's 3.3V to achieve a 3.3V high state, or the GND line to achieve 0V low state.

Our PUD board takes the messy wiring out of adding a pull-up or pull-down resistor to your circuit. Simply wire up the sensor output to the single pin on the PUD board and add a shunt jumper to either pull up (u) or down (d)! Therefore when you apply a signal voltage from your sensor or switch, the Pi is easily able to sense into which logic state the pin has been pulled! No more trouble from floating I/O's!

The PUD boards connects across GPIO pins 11 to 18 (17 to 24 in BCM speak), and adds a jumper configurable pull-up or pull-down resistor to each GPIO pin: 11 (BCM 17), 12 (BCM 18), 13 (BCM 27), 15 (BCM 22), 16 (BCM 23) and 18 (BCM 24). Pin 17 (3.3V) & pin 14 (GND) are used to tie the pins!

The PUD Board Features:

  • Add a pull-up or pull-down resistor to your GPIO with the swap of a jumper!
  • Compatible with all Raspberry Pi Models Inc. A /B /2/3 & Zero/ZeroW
  • Tiny board means it's easy to integrate into any circuit - takes up just 8 GPIO pins
  • Connects across GPIO pins 11 to 18 inclusive (BCM 17 to 24)
  • In-line 1kΩ current limiting resistors on each GPIO
  • 10kΩ pull-up or pull-down resistors on each GPIO
  • All 6 GPIO pins can be configured independently 
  • Includes 6 x 2 Pin Shunt Jumpers & 1 x PUD Board
  • Jumper configurable pull-up or pull-down resistor on pins:
    • 11 (BCM 17)
    • 12 (BCM 18)
    • 13 (BCM 27)
    • 15 (BCM 22)
    • 16 (BCM 23)
    • 18 (BCM 24).
  • Pin 17 (3.3V) & Pin 14 (GND) are used to tie the pins!
  • To pull pin up, connect the jumper across "u" and the center pin
  • To pull pin down, connect the jumper across "d" and the center pin
