Copperhill’s third-gen, $65 “PiCAN3” HAT features Raspberry Pi 4 support and a SocketCAN-ready CAN-Bus 2.0B port. The HAT has an RTC and is powered by a 3A, 6-20V Switch Mode Power Supply that can also power the Pi.

On some Raspberry Pi’s of mine I had problems running node-js as a service as described here. The only hint of a problem I got was a cryptic “run nvm use latest/*” in the setup. I also remembered a post saying that node-red does not like nvm.
So how to get rid of nvm you have it installed?
First
sudo npm uninstall nvm
to remove it.
Then remove the lines nvm add to your .bashrc file. They are located at the end of the file and look like this
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Now remove the nvm config folder
rm -rf ~/.nvm
Now run the node-red setup/update script again and after that services will work again.
I had problems installing node.js using the official install script. The problem
is that the update step fails. There is no clue in the install log file as far as I can see.
To solve the problem I installed node/nmp following the excellent guide here
After you gone throw the steps in the guide just run the install script again and everything will be alright. At least it was for me on a machine running Debian Stretch and some other boxes.

#VSCP – Last year as a teenager
Today it is 19 years since the VSCP project started. A long time. Many hours of work has gone into this project. But nineteen now. Time to grow up. This is the last year as a teenager. I think I have the path ready for this grow up phase. But more on that later. Today we celebrate.

State of #VSCP
Just a post to let you all know that VSCP is still alive even if not many things have happened for the last months.
As I wrote before I had some surgery in January this year and a follow up operation on that in June. Sadly I got a bad infection in the operation wound so I had to stay for some time at the hospital, but now I am home again eating tons of antibiotics.
Well things are pretty good now and I hope I am in working condition next month or so. But apparently one never know with deep infections, they often come back with full force. I, of course, hope it will not. 😉
I am sorry for all this talk about my health lately, everyone have enough with there own health and wellbeing, but this is my reality right know and I just want to indicate that VSCP is not dead. or even sick. It’s just me and I am in a good mode after all.
Have fun!

In 2017, we (balena) embarked on a mission to build the ultimate flashing media. As a software company, we didn’t realize the hornet’s nest that we had stepped into. Little did we anticipate that in the process, we would end up re-examining the wheel at every step, going through eight

With each new cellular standard, we see fresh claims for the “end of Wi-Fi”. When 3G was announced, it promised to make Wi-Fi (802.11b) redundant, which clearly turned out to be wrong. With 4G (LTE), this story repeated itself, claiming it would put Wi-Fi (802.11ac) in the bin.

State of #VSCP
It’s been many months. I have more or less been unable to do any serious VSCP development. All plans for the first half of 2019 just went out of the window. Even if that hurts, loosing such amounts of time, I had a second operation last week and the doctors says I am allowed to do some programming again from the end of the month. I look forward to that.
So hopefully “the state of VSCP” will be less about my scars and more about project progress after this summer. I have done quite a bit of the new VSCP works client during this slow time and hopefully some initial code will be available publically also very soon. JavaScript is still a little “strange” for me. But I like Electron and node.js more and more.
I hope everyone reading this will have a very nice summer. A Blackbird, named Pavarotti here on the hill, is singing for me and there is nothing in the world more beautiful than his song. Enjoy the summer my friends.
