Here’s the steps to share your OSH Park project:

Step 1: Click ‘Start sharing’

Navigate to your Projects page and click the ‘Start sharing‘ link for the project that you wish to share:

https://oshpark.com/users/current

 

Step 2: Edit your shared project content

The shared project content is formatted by Markdown syntax.  This is a good guide:  Markdown Cheatsheet

We recommend you include a link to your projects primary documentation such as Github, Hackaday.io, Hackster.io, or Tindie.  Remember to publish your BOM as well, since your project cannot be built without it.

Here is what the shared project edit page looks like:

 

Step 3: View the Shared Projects directory

Navigate to the Shared Projects directory page and you should see your new shared project at the top.  You can also search for shared projects from this page.

Open Panzer Sound Card

Open Panzer Sound Card

The Open Panzer Sound Card is a work in progress with the goal of bringing inexpensive, high quality, and open source sound functionality to RC models but especially to tanks using the Tank Control Board (TCB).

The board is actually made up of two components. First, an off-the-shelf PJRC Teensy 3.2 is used as the onboard processor. The Teensy is then plugged into a socket on our custom carrier board that adds a Micro SD card slot (max 32 GB), an additional 16 MB of flash memory, an LM48310 2.6 watt audio amplifier, and headers for external connections.

I/O Expander for LED Arcade Buttons

fustini, , , , , Leave a comment

Teensy creator Paul Stoffregen has shared a new project on OSH Park:

I/O Expander for LED Arcade Buttons

The Monolith Synth Project needed to use a large number of these LED lit arcade buttons.

Dimming of the LEDs was required. Initially I considered using this Adafruit 16 Channel PWM board. But the LEDs in these buttons have integrated resistors which require 12 volts, so 16 transistor circuits and another board for reading the switches would have also been needed.

It uses the same PCA9685 chip for 12 bit PWM control on every LED, with mosfet drivers to handle 12V outputs, and also a MCP23017 chip to read the buttons. Every button has a discrete 1K pullup resistor (rather than using the higher impedance on-chip pullups) to help with use in the same cable bundles cross coupling to 12V PWM signals.

ic_mkl04_refboard2

Teensy 3.6 DIY Reference Board

A known good reference board for testing the MKL04 chip when building a DIY Teensy 3.6. Refer to this table for the differences between Teensy 3.6 and other models. The soldering friendly LQFP package (at least more friendly than BGA) is used on this board.

E-Ink controller with ice40 FPGA

E-ink Display Driven DIY

E-ink displays are awesome. Humans spent centuries reading non-backlit devices, and frankly it’s a lot easier on the eyes. But have you looked into driving one of these critters yourself? It’s a nightmare. So chapeau! to [Julien] for his FPGA-based implementation that not only uses our favorite open-source FPGA toolchain, and serves as an open reference implementation for anyone else who’s interested.

Watch the E-Ink controller in action:

Servo Shield for OpenMV

Radomir Dopieralski created this PCA9685-based servo shield for the OpenMV machine vision board:

Servo Shield for OpenMV

OpenMV has a couple of pins that you can use for connecting servos (for example, if you want to mount it on a pan-and-tilt base), but you can’t use those if you also want to use the WiFi shield or any other shield that uses up a lot of pins. Practically the only pins left to use are the I²C ones
