Comment on The CANable: a small USB to CAN adapter by Neil Emiro

Ethan, I know this is long since a passed project for you. I am still using CANable devices. I recently tried to get it working on an 83.3kbps bus, and while CANgaroo is showing it connected, it is not passing any traffic. I can plainly see that the data is there on an oscope. If I change the programming of my circuit to 125kbps, it works fine, but I am trying to interface down at the lower speed. Is there a setting I am missing? Putting the termination resistor in or out does not make a difference. Thanks!

Hi, the download links are down. Do you mind adding new links. Thanks

Hi from almost 2025.
Did this project failed to get to sales? I wish to buy one, but can’t find any.

And how do I quit a session with IRC ?
Shoud I type “quit”.
Or quit I just close connection, and server will end my session ?

Comment on Therm: a Tiny PID Controller by ThermTiny: Precision Control with a Compact PID Controller

ThermTiny: Precision Control with a Compact PID Controller — Thu, 15 Feb 2024 07:21:53 +0000

[…] Therm is a very small PID controller with an OLED display, thermocouple interface, and USB port. It can switch an external solid-state relay for driving large loads, or a transistor for driving small loads. When attached to a computer, it enumerates as a USB serial port for easy control and logging of data. The design is based around a STM32F0 microcontroller and the MAX31855 thermocouple-to-digital IC (note: an RTD version of therm is in the works).All PID parameters and settings are configurable from the on-screen menu. Therm also has a menu option to reboot to the DFU bootloader so the firmware can be updated without a hardware programming dongle. Currently, therm only supports a single setpoint, but we plan on implementing multiple setpoint support for reflow oven control and other applications in the near future.Therm has screw terminals to connect power input (up to 12v), a solid-state relay, and a thermocouple. Pads on the bottom of the board expose the SWD interface for debugging and programming in a fixture or with a PogoProg adapter. While all the core features of therm are complete, some have yet to be implemented “namely saving settings to non-volatile memory and setpoint control over USB”. In the coming months we plan on cleaning up the firmware, finishing up the missing features, as well as performing some extensive testing on our latest hardware spin.

Comment on EC155 PID with Arduino by Daniel

I am making a PID controller using an Arduino for the same espresso machine. I was wondering what coefficients you used for P I and D. Also did you model your system theoretically and use a transfer function or did you just guess and check

[…] Matthew designed the system “to bring sensors and actuators together through automation to allow hobby growers to focus on growing verses constantly monitoring and adjusting the environment to keep their garden stable.” HydroBot achieves this in three ways: facilitating optimal growing techniques that adapt to changing conditions; simplifying control interfaces to make setup and use easier for less tech-savvy gardeners; and using modular components to increase flexibility for every imaginable garden configuration. To read more about Matthew’s ingenious HydroBot and the vision behind it, visit his blog at Protofusion. […]

Ethan, does the CANtact BUSMASTER fork work with the Candlelight firmware or does it need SLCAN?

This is great! I want to add PID for mine, but I also want to be able to control the pump. So you have any information on the schematic of the machine itself. Thank you for this great content

You have a command typo, you need to prepend “:” (without “”) to the first word after the channel name.
