That’s it for this week’s Hacklet, As always, see you next week. If you want to see more, check out our Propeller Project list! Did I miss your project? Don’t be shy, just drop me a message on Hackaday.io. There are a ton of Propeller projects on Hackaday.io. He’s now working on modeling a 3D printed case with Blender. At the center of it all is a Parallax Propeller programmed in SPIN. A GPS and compass module provide all the navigation data Pipman needs. Input comes through a 5 way navigation switch. version uses a 4D systems TFT LCD to display those awesome graphics. This Personal Information Processor (PIP) has spawned hundreds of projects from cosplayers and electronics hobbyists alike. ![]() There’s just something about the Pip-boy from the Fallout video game series. With 256Kb of RAM, 16 MB of Flash and an LED, the entire system fits in a DIP package smaller than a stick of gum.įinally, we have with Pipman GPS Watch. has taken this code and ported it over the Zynq-7. Back in 2014, Parallax released the Verilog HDL code for the Propeller core. The core of the system is a Xilinx Zynq-7 chip, which contains an FPGA and a Dual Core ARM A9+ processor. Soft Propeller doesn’t use a hardware Propeller at all. created Soft Propeller, his entry in the 2015 Hackaday Prize. All the parts live on a custom PCB milled using his CNC router. Command and control is via X-Bee radio modules. This module contains a gyro, accelerometer, compass, and altimeter all on one tiny board. Locomotion comes in the form of two stepper motors. B-BOT’s primary sensor is a Pololu AltIMU-10. While slower than assembler, SPIN was plenty fast enough to solve the classic inverted pendulum problem. used B-BOT to learn about designing with the Propeller and programming in SPIN, the Prop’s built-in interpreted language. has expanded the L-Star to support the Ohio Scientific C1P and CompuKit UK101, both early 6502 based computers. As you can see from the photo, it’s quite capable of displaying Woz in ASCII. The system takes input from a PS-2 keyboard, and outputs via composite video, just like the original Apple I. The project uses a 6502, with a Propeller handling just about everything else. ![]() The whole thing fits on a Propeller proto board with room to spare. He built upon the success of his Software-Defined 6502 Computer project and created L-Star. Inspired by recent Apple I build, wanted to see if he could replicate an Apple I with minimal parts. We start with retrocomputing prop star and L-Star: Minimal Propeller/6502 Computer. This week’s Hacklet is about some of the best Propeller projects on Hackaday.io! The Propeller saw commercial success, and continues to have a loyal following. Cogs are connected to I/O pins and other resources by a hub. Designed by, the Parallax Propeller has 8 cores, called cogs. Parallax didn’t just jump into some cookie cutter ASIC, they made their own parallel multi-core microcontroller. Still, for a relatively small company, jumping into custom chips is a big leap. ![]() The Propeller is a good choice over other microcontrollers when a low system part count is desirable due to its ability to provide direct video output and an easy interface to external peripherals such as keyboard, mouse and VGA monitor.In 2006, Parallax, Inc wasn’t new to the electronics business. Its eight symmetric 32-bit processor cores (also called "cogs") are united by shared memory, managed by a central "hub," and have common access to all 32 I/O pins. The Parallax Propeller is a unique multicore, multi-processing microcontroller with shared memory and a built-in interpreter for programming in a high-level object-oriented language, called Spin. ![]()
