They have 3 versions of the Canaduino boards. In addition to the one above 
they have one with 4 relays and one with 6. The boards have both analog and 
digital inputs and outputs in addition to the ability to some relays.


I have the 6 relay version. I am looking at it as a way to enhance an 
existing product used for the monitoring and control of industrial CNC machines.

Another Canadian supplier of semi-industrial microcontrollers is Universal
Solder out of Yorkton, SK: https://www.universal-solder.ca

A particularly handy board they sell is the CANADUINO PLC 300-24 —
https://www.universal-solder.ca/product/canaduino-plc-300-24-arduino-mega2560-based-diy-kit/
— that's basically an Arduino Mega but with proper relay outputs and 0-10 V
analogue I/O, all protected. The owner's also really knowledgeable about
industrial applications and is super helpful.

Also, for local cheap microcontroller bits, there's
https://www.simcoe-diy.ca/ in Barrie. That's where I get my weird
MicroPython boards.

I wouldn't be so negative about capes and shields -- they're where you put
your own peripherals and interface circuitry.  Start by mapping out the
sensors and drivers you're going to connect to the big hardware, and work
inward from there to the microcontroller.  The hard work is out there with
questions of noise immunity, and the all-important question of what the
cutters and conveyors will do if the computer glitches or stops working.

Olimex used to be good for microcontroller boards.  Service was pretty
good, even though they shipped from Romania.  Some more local vendors are
ABRA, BCRobotics, Creatron right in Toronto.
There's not much to soldering an ATmega processor to a board;  the
processor plus a voltage regulator plus maybe a crystal, plus a half-dozen
capacitors and it's done.  There are gcc toolchains around for many of the
popular lines of controller, AVR and ARM in my experience.
The mission-specific circuitry outside the computer is the real challenge.

Yes I had red of the RPi Pico.
RPi is rather interesting in that you can buy quantity 1 of the board

reasonable!
One project - - - - there have been questions over what I'm trying to do

some idea of what I'm doing.

I want to have one electric motor for moving like a large mass of material
forwards (and back if I wish), then there is a higher hp motor to power a
whole bunch (2 m worth) of blades and then there is a third moderately
sized motor that moves the gang setup up and down. The gang is turning
at a fairly high rpm (7500 rpm in the prototype and 10k in the design) and
moving quite quickly, 2 m in under 10 to 12 seconds. So the load on the
gang is monitored so that if the load moves over say 103% of rated that
the gang movement speed is slowed or if the load is under 80% that the
gang movement speed is increased. So there, planning is anyway, a vfd

small system. This system may be working for as much as hours per time
and multiple times per day. Overloads/heating will also be monitored.
This is the kind of equipment that I don't want to have to babysit but it

Re: [GTALUG] micro controllers

[Chris Tyler via talk]

I've been using ESP8266/ESP32 boards, but the RP2040 used in the Pi Pico
looks interesting as it's cheap, dual-core, and has the PIO units on it.
The Pico has weak network connectivity, but the RP2040 chip is showing up
in other boards like the Arduino Nano RP2040 Connect, which has WiFi+BT.
Haven't heard pricing or availability. (Other RP2040 boards are coming from
SparkFun, Adafruit, and others). Could be an interesting option in a space
that intersects with the ESP32 boards (looking forward to comparing ESP32
[Extensa] vs ESP32-C3 [RiscV] vs RP2040+Wifi+BT [ARM C-M0+] boards).

You can also make your own board using an ATtiny or ATmega chip. The Arduino 
boards I've seen always(?) have ATmega328's on them. That limits your 
options somewhat as to amount of program memory. There is also the Beagle 
Bone boards as a possible alternative to Arduino. ATmega chips can be as 
large as 40-pin so there are plenty of I/O pins. There is also the AVR32 
(32-bit) line of devices.


There are many Pi variants available: BananaPi, OrangePi, and NeoPi to name 
three that come to mind.

I snagged two of them already, purchased two weeks ago (at launch) from

On that note, we can expect short supply and rising prices for 
electronics for the next year or two. The fabs that actually produce all

This couple with no new capacity. The auto makers are making noises

Take a look at https://www.phidgets.com/
They have a range of compatible  modules that you can use to build up a 
control system.
It is a bit more plug and play than trying to work with arduino boards 
and shields.


Another choice for lots of stuff and ideas is https://www.adafruit.com/

I think when you said "Raspberry Pi" above you were referring to the
SBC, but they have very recently issued their own microcontroller
board, "the Raspberry Pi Pico:"

https://www.raspberrypi.org/documentation/pico/getting-started/

In fact they don't seem to have shipped yet, but they're going to be
selling for $5.25CA each.

I mention it as an alternative to the Arduinos, with the caveat that I
know very little about microcontrollers.  I own an Arduino Teensy, and
have done a little programming on it, but that's all.  And my
understanding is that the reason the Arduino made such an impression
on the market is because it's a lot easier to program than the older
microcontroller boards that existed before it.  And I suspect that
initially, the Pi Pico will suffer from much the same problem.  I say
"initially," because the Pi itself has been so successful that it may
drive sales of the Pico which would in turn lead to development of the
coding environment for the Pico.

Anyway, I thought I'd put that out there in case the Pico and/or its
MicroPython (or C/C++) development environment sounds good.

(This is of course NOT industrial grade.)

Re: [GTALUG] micro controllers

[Mauro Souza via talk]

It depends on what kind of connectivity do you need, and how fault tolerant
you have to be.

If you need mostly wifi/bluetooth, there's a very nice line of
microcontrollers: ESP32. They have a lot of variants, so you can find the
one you want.
If you need IO pins, Arduino is the way to go. They too have lots of
variants, with more pins, less pins, large, small, and they are very easy
to program.
If you need processing power, the RasPi variants are the ones you should
use. They run Linux, they have beefy processors (for an embedded platform),
lots of RAM, and are accessible too.
STM have some industrial-grade microcontrollers too, and I believe you can
program them with C. I have a STM Discovery in a drawer somewhere...

Fault tolerance can be achieved using more than one board, and depending on
the equipment you are controlling, you can use some combination of OR-gates
or counters to define if you are activating it or not. As the boards are
cheap, it won't be much expensive having 4 Arduinos giving the same input.

I have had great success with Arduino mega, mini and Adafruit Huzzah
feathers.
Not in industrial settings though.
The Huzzahs are relatively inexpensive and have wireless built in.  All
can be developed with the Arduino IDE, which is tolerable.

I use the Huzzahs for indoor/outdoor Temp/Humidity/Pressure sensing, for
tracking power consumption on my hydro and have used it for net enabled 
fan control and for, errr, cat feeding scheduling (Not a success, but 
due to the cat).


I bought all the micros at Creatron when it was open, and the odd 
purchase of ICs from Amazon has worked for me.

Re: [GTALUG] HP Z420 + rx5600 + MSI MAG272CQR ?

[steve--- via talk]

 Just installed Ubuntu 20.04.   No issues of any kind, seems to
work great..

 Was easier getting my rx5600 up to full res than on windoz
checking out some colour linux colour calibration stuff.

 So.. what is a "good"   OS browser? These days.

Chromium is a */pain/* to build. If you're not being paid to work on it, 
it's a low-value, high cost effort.


This has caused even some folks to reconsider offering it, except as a 
binary blob with less functionality than the Chrome binary blob.

Ah, you're really not gonna like Ubuntu now, then. Chrome is *only*
available as a snap. The deb is a stub that reinstalls snapd and the
