An Interview with Matt Richardson - Raspberry Risorgimento Regent

Welcome Matt Richardson, the first US member of the Raspberry Pi Foundation!

• The foundation has about 15 people in various roles (hardware, admin, education, outreach).
• There are now approximately 4.5 million Raspberry Pi's in the world! Dave was curious how many were orphaned but Matt says "they don't expire".
• The official add-on boards are called HATs. Adafruit coined the term "Plates" for a similar concept.
• The Model B+ moved from a smaller connector to a 40 pin connector, with much more pin fanout from the chip.
• Each HAT has an EEPROM onboard to tell the Broadcom chip how to configure the pins.
• Matt has published a wide range of projects on his portfolio site. Some of the best known are the awesome button and the enough already projects.
• He has also attended the sketching in hardware conference, which seems to fit Matt's skillset well.
• While working at MAKE and before joining Raspberry Pi, Matt attended the NYU ITP program.
• It was at ITP that he developed the descriptive camera. That uses a BeagleBone, a webcam and an interface to Mechnical Turk. In high pressure, long duration showcases of the project, Matt redirected the images to his partner, who supplied funnier than normal descriptions of the things being captured.
• Matt's focus has been on implementing other technology blocks, which gave him a good view on how people interact with technology, specifically the UI.
• Dave mentioned that engineers used to pay a fortune for GUI library ($10K+) for something like an 8086 PC104 board, because it was worth it to have something that works.
• Matt did a bike lamp project that tells you how fast you're going using a Raspberry Pi and a picoprojector.
• As an author, Matt has written (and co-written) 3 books
  • Getting Started With Raspberry Pi
  • Getting Started With The BeagleBone
  • Getting Started With The Intel Galileo
• Just a few days ago, the Raspberry Pi 2 was announced!
• It has a quadcore, ARMv7, 900 mhz processor and averages about 6x faster processing if multithreading is possible. It is moving from the Broadcom 2835 to the 2836.
• Since it uses the ARMv7 instruction set, it can run things like Ubuntu and Windows 10. Previously the most popular distro was a custom one called Raspian.
• It also enables interesting new applications like using Robot OS (ROS). That can only run on an ARMv7.
• The new board uses the same B+ header but has some small physical differences.
• The hardware is not open source, but the foundation is working on opening up the software used in the graphical side of things.
• The main focus was on low cost (hitting a $35 price point) and the tradeoff is using high volume chips that are not open to the public. This is similar to Bunnie's take on the MediaTek chipsets (and how he got around it).
• Matt will be working on getting the RPi into the US education system, which is very fragmented. There is a good footprint in the UK. They run workshops for teachers called PiCademy.
• The board can work as a great gateway for people into electronics. Students enjoy running Minecraft on it using a port called Piper.
• How low can you go? Rip off some headers and
