Do you accept bitcoin donations?


Me: Sorry, I don't have any sort of crypro currency on my discs. I prefer hardware coins since they have a certain value caused by the metals used ;-)

Dear Sir,

This project is very usefull to my project.

just i want one modification I want preset length and ruler reach preset leaghth one output goes high

and it will reset by another input.

thanks

Me: Well, if you'd like to make changes on the software, you are allowed to do so. The source code is available as Download and the license is free.
I will implement that type of functionality some day, but for sure not quickly, because I have too many projects running...

Excellent useful makeshift project., both educational and very functional. You have the equivalent of a standing ovation from me on the level of detail, innovation, creativeness, and theoretical explanation to setup this project. Well Done!

Me: Thanks!

Hello Norbert.
Great example of Arduino and optical encoder, a little bit crude  - I wish it will be more accurate.  Can I suggest you way to improve this  - attach linear optical encoder  to you workpiece, say with magnets. Or make a movable caret that will measure linear movement and will also carrying workpiece.

Thanks
Gene.

Me: More accurate than half a millimeter for parts cut by hand? First of all you'll need a very good mechanics to get better results.
