MAKER: Luke Kenneth Casson Leighton
Luke is a Libre Hardware and Libre Software Engineer, he is currently fulfilling an eco-conscious Crowdfunding campaign (EOMA68 on Crowdsupply). The idea is to create mass-volume products that people can repair, upgrade and maintain for themselves, saving a lot of money in the process. That means it has to be entirely open (100% libre) including the casework, which must be 3D printable so that people can repair it or replace it for themselves. He is designing a 3D printer to support the project because he has a huge amount of 3D printing to do, to fulfill his promises to the backers.
Project 1: RD3D
PROJECT 2: EOMA68-A20 Computer Card
The EOMA68-A20 Card is the very first in a decade-long series of EOMA68 Computer Cards.
PROJECT 3: EOMA68 15.6in Libre Laptop
The EOMA68 Libre Laptop Housing basically turns any EOMA68 Computer Card into a fully-functioning laptop. It has a 1366×768 15.6in LCD, built-in USB-based audio to give stereo speakers and a built-in microphone; it has an extra MicroSD Card slot, and the battery is a stable Lithium Polymer battery (from an E-Bike company!), which
provides an estimated 8 to 10 hours of operation. It also only weighs 1.1kg which is extremely unusual for a 15.6in laptop. This contributes to its robustness, even when PLA is used as the 3D printer material.
PROJECT 4: EOMA68 MicroDesktop
The Micro-Desktop Housing is a very simple minimal way to gain access to the standard ports of EOMA68. The MicroDesktop Housing therefore extends a Computer Card’s ports to include 2 USB, VGA Video, Micro-SD,
and for tinkerers there is an internal GPIO, UART and I2C header.
PROJECT 5: EOMA68-RK3288 Computer Card
This Card is under development as a future Quad-Core upgrade and will come with 4GB of RAM. It is the same processor that was used in the highly successful Acer C100 Chromebook, and as such has full libre source code available for it, right down to the bare metal. The first prototypes have been made and will be brought to show at Shenzhen Maker Faire 2017. News and progress can be found at http://rhomb
PROJECT 6: “Taobao Clone” 3D Printer
PROJECT 7: Riki200 3D Printer
In combination with Dual Linear rails and Triple Lead screws which may be independently controlled to give auto-bed-levelling if a Z-probe is used, this 3D printer is unique in its flexibility, is sourced entirely from parts commonly found in the Shenzen eco-system, and yet has the kinds of features normally reserved for 3D printers in excess of $USD 2,500.
As it is a fully-libre GPLv3 licensed design, Its project page is http://repra
