PCB CNC Enclosure – Finishing the bottom
Finishing up the bottom section of the CNC PCB Enclosure.
Rework of an early prototype to use with the canbus controller and to have an additional RS485 device on the bus. HCControl2 is in the RZR 1000 S at this point and replaced the relay for the lightbar and winch. I’ll be adding reverse and rock lights soon to integrated with CanBus to enable turning on the reverse lights in reverse and auto rock lights on at low speed.
In this video I build a prototype of the multiplexer board. Stencil process, placement and reflow of a double sided board with parts on both sides. PCB stenciling, placement and reflow by hand for the prototype process.
This is a multipart series of design, prototype and build of a small multiplexing system for UTV’s. Initially this will replace lighting and winch relays with solid state control. In this part 3, I go over the base software using OSX with the STM8.
I explain using OSHStencil to prototype a board with double sided parts. I also discuss high side switching with a MCU. The first testing happens with two development boards from STMicro using a STM8 Discovery board.
RZR Mini Multiplexing Part 1. This is a multipart series of design, prototype and build of a small multiplexing system for UTV’s. Initially this will replace lighting and winch relays with solid state control. The goal is to replace the traditional use of a relay in the rzr for winch and lighting control. Later I will integrate this with canbus work for speed and gear info from the Polaris RZR to turn on reverse lights based on gear selection and turn on rock lights at low speed.
I put this together for testing. Package download is below (At Very BOTTOM). You will need to homebrew a non-standard ngspice (doesn’t have ngspice lib by default). Its avail here https://raw.githubusercontent.com/jmaibaum/homebrew-core/8ac02ae933c4cd5d1f661b6a2bda2f429d5f1e87/Formula/ngspice.rb . Note the NGSpice homebrew is in flux and this version is done jmaibaum.
An open source codec for compression is up and going (CODEC2).
AMBE is much easier to implement and get ahold of.
Remote heads are beginning to pop up commercially in the FlexRadio line.
More embedded projects/products including SM1000, FlexRadio head unit, and many many DStar node adaptors.
DMR radios have hit the market to warm up the digital voice market, many which are under $300 new.
