Midwest RepRap Fest in 2 weeks

Every year, sometime in March, the world’s preeminent 3D printing enthusiasts gather in the middle of nowhere This is MRRF, the Midwest RepRap Festival. It’s only two weeks away. You need to come. Get your (free) tickets here. I’ll be there, and Hackaday is proud to once again sponsor the festival. I need to backtrack a…

Machinekit is a platform for machine control applications.  It is based on LinuxCNC and can drive mills, lathes, 3D printers, laser cutters and more.

Machinekit can run on an Altera SoC which combines a hard silicon ARM core with a FPGA.  Charles Steinkuehler has been working with the DE0-Nano development board from Terasic.  MachineKit runs on the ARM core with the FPGA configured as a MesaNet card:

Charles designed a DB25 connected interface board, with pin-outs matching the P2 and P3 headers on a 5i25

cdsteinkuehler has shared the board on OSH Park:

Chicago Robotics Corp is exploring 3D Printed Robotics with Simula:

simulated life-forms for use in research and entertainment

The robot is programmed with Arduino IDE:

Programming Simula

You might choose to program Simula by yourself from scratch, modify our existing software, or just keep up with our latest simulations.

Arduino Library for the Simula Boards and Modules is on GitHub:

Chronio

Arduino-based 3D-printed Watch. By not including fancy Wifi and BLE connectivity, it gets several months of run time out of a 160mAh button cell. The display is an always-on 96×96 pixel Sharp Memory LCD.

Hardware

  • Microcontroller: Atmega328p with Arduino bootloader
  • Real Time Clock: Maxim DS3231 (<2min per year deviation)
  • Display: 96×96 pixel Sharp Memory LCD (LS013B4DN04)
  • Battery: CR2025 160mAh coin cell
