Hello. I have this project in mind. I would appreciate your suggestions. I fly a small airplane and it has 4 1.75” rectangular cut outs for old indicator lights in an enclosure that has been emptied out on top of the panel. I thought I could fill those with small displays and hide a pi behind in the...

hi, could you elaborate on the wiring? Id really appreciate it if you could share . thanks

I too need to rust off my electronics.

let me try to figure it out, and i´ll be sure to post the result , in case it can help someone else.

Hello guys im stuck in project, i started using this forum post https://www.raspberrypi.org/forums/viewtopic.php?f=32&t=127870&sid=457f2cde71e4badafaef7e735e68fb66&p=958526#p958526 But this example works fine when the coin module pulses at 5v. the one i have pulses at 0.7v. My electronics are very b...

Hello, again. I've got good news and bad news. The good news is, that I actually got a reply from a Chinese guy that sells this exact model, and he confirmed the pulse is 0.7v. The bad news is I'm now lost where we can use it on the Pi or not. :lol: I appreciate your patience Chris, the help means a...

Hello Ground is connected. The pin is ok I tested another and if I switch to the other code it does show the dozen coin drops. I added a 10k resistor from the pulse to the pi. It shows about 50 "drops" for the 1 coin. That's the only way I can get the acceptor to display something on the pi But that...

Hello again. I went to the electronics shop and bought new resistors and some jumpers and started again from scratch.... but Im guessing this YD-7 series units do not output 5v. I´ve searched the net and found similar units (not identical) than output .004v on standby and .7v on pulse. See http://cd...

agidi

Hello thanks for the tip. I found a NO and NC switch on the coin acceptor. With the switch on NC i tested the with the voltmeter on the GPIO pin. On Standby i get a steady 0.43v On coin drops i get a RISE to 0.72v (when i drop a $10coin which sends 10 pulses) if i drop a $1 coin my voltmeter shows 0...

Hello again. So i built the voltage divider as per the diagram. thanks Im just missing one resistor. http://screencast.com/t/oILHKvMi With the voltage divider things changed a lot. The old code , that sensed coins, now shoots print messages reaaaallllyy fast. http://screencast.com/t/xhbuazNaz Your t...

I had not seen the Code, thanks! I tested it and for starters i got an error on with the except pi@raspberrypi ~ $ sudo python pruebatres.py File "pruebatres.py", line 17 except KeyboardInterrupt: #Just clean everything on exit... ^ SyntaxError: invalid syntax pi@raspberrypi ~ $ So i just commented ...

Much appreciated Mr Chris.
With Crayons please

Yes some diagnostic test code would helpfull abusing of your kindness
I'm getting some Python for dummies books tonight.

agidi

Trust me, I'm more confused than you, it's been 19 years since I coded anything or solder electronics, :shock: My multimeter is still from RadioShack! :lol: But I'm getting there. The code that sort of works I copy pasted it from a forum. Yours shows me nothing so I'm asuming I'm not doing something...

agidi

Hello Kindly requesting an opinion. Im really new to this. I tried the posted code on this forum, in all it stages. But i cant get not one to work on my setup. However, i managed to get this one to sort of work. This code sends dozens of print lines to screen, im not sure why, but at least i know is...

agidi

Wow thanks. I can't wait to get the coin acceptor from the mail to test it.
Thanks!,,much appreciated

agidi

Hello Chris and crew, i just boarded the same boat. I just got the 2x16 LCD screen and wifi working and im eagerly waiting for my coin acceptor module to arrive. Wondering what was the code that finally worked for you? im too trying a 3 coin module and would like it to add , until i get to the write...

Hello Im trying to do the following but dont know where to start, or if there is something similar already working not to start from scratch. I want to setup a display in portrait mode. With a camera, either this one or some other USB camera on top. and 2 large push buttons, green and red. Have the ...

Did you guys solve this?

Need to sense light and activate relays too.
