Re: Backup SD card to .IMG file

Concerning the target for the img file: I have failed to use an NTFS hard drive directly connected by USB as the target for the output img file. :cry: But I have succeeded in using an SDcard in an USB carrier directly inserted into the RPi after reformatting it as ext4. Now I am facing a problem wh...

Do I have to run imgclone as sudo or does it switch internally?
yes you need to run as sudo it will not switch internally and you don't need to run inside the directory if you provide full path to the backup destination file.

Well I'm not an expert but clearance is 0.086 you think that is not enough? I've added buttons and made display work so the project is now almost 100% finished, the machine is back in the original place and doing all wash independent!

Backup SD card to .IMG file

With the piclone program that comes with the standard installation of the Raspberry Pi OS you can create a backup of your SD card to a second SD card while it's active. Now I've modified this program a little bit so it will create backups to an image (.img) file on an external USB drive or shared ne...

Re: WashbearyPi - Controlling a washing machine with a Pi

Made some changes to the circuit for speed detection, used an opamp because it is more sensitive at low speed (20rpm). Could not find datasheet of the NTC so I've pored some water in and turned on the heating then measured water temperature and compared with the ADC value. until the water level sens...

Washberry.zip I've used a Microchip PIC18F2550 for controlling the triac because it has to be done with perfect timing. Maybe it's better to choose for PWM and a mosfet? The ...

Yes searched the number and it is a triac. It is on the AC side (before the rectifier).

Re: WashbearyPi - Controlling a washing machine with a Pi

I'm working on similar project now :D. When I take a look at the controller PCB in the washing machine I see Samsung has put a rectifier bridge after the triac. Don't know why but I guess they want to make the motor act as a resistive load by feeding DC to it?
