Has anyone used these? They could decrease the profile size of a PIR style sensor. Also 3.3V. Thoughts?

I have it. My first 3d printer so I can't compare. I hooked it up to a octoprint pi setup. I really like it. I have already changed the hot end for a volcano setup.

Hi @mtiutiu - Did you ever get a chance to make a BOM? Most of the one @tonnerre33 one makes sense but I only bought two boards so being a little cautious

Thanks!

@sundberg84 It was your project that inspired me - The electronics part etc is not the hard part IMHO on these projects - it is the WAF and how tidy I can have them in the house. Hence I was looking for a box that I knew I could stick a screen and arduino in and not have to worry about it. Thanks for all the work!

Thanks @mfalkvidd !

Any BOM?
I still have these PCBs and want to finish em. Can't source a crystal/resonator of about 5x4 mm.

I am going to try out http://ie.farnell.com/stmicroelectronics/m95128-wmn6p/serial-eeprom-128kbit-10mhz-soic/dp/9755870

Will report back.

How are you getting on with it? What spare pins are you using etc?
Have one sitting on my desk making me feel guilty for not hooking it up!

I use a reed switch on my gates - when they are in contact the gate is closed.
You could put more at the open points for fully open but I only cared about closed or not. I assumed for 20 secs after they started opening they are opening else they are open.

When I close the gate I assume closing until the reed switch shows closed - of course opening the gate during closing will reopen (I also have IR to detect car so gate will not close onto a car).

Hi @koresh - I had a little accident on the AC side :-). I was wondering what values the 2 resistors (TH and SMD) and diode are ? Thanks!

@giltesa Congrats!

@giltesa Looking forward to seeing results! Great work.

@dbemowsk I am trying to tune that at the moment! Lots of stringing.

Hi @Koresh - Any gerbers etc yet? Thanks!

@gohan Thank you!
