Any guesses on what it does?

YES, I did use hot glue to mount the LCD display! No there is no duct tape inside, so it's OK!

I like this one....
Depth?
Ir?
Distance?
Color?
Missed one, which would be super impressive...
Contrast imaging
Than I guess what to do with it

close, ultrasonic and SD Card.

Off contact?
Some kind of densitometer?

So distance, hmm.. To many options... Based on the onslaught of LED and Emulsion threads. I would guess measuring emulsion thicknesses is your plan

going on the press. . .

homemade no-shirt sensor?
or some kind of counter/monitoring device for performance?
-
no shirt sensor is to difficult, especially if a revolver program is involved. I am guessing possibly trying to measure ink deposit values?

I wouldn't think that an ultrasonic setup would have the accuracy? but maybe measuring ink levels in the screens?

other cool ideas:
1. "Registration checking doohickey" I might need to trade mark the name but possible. A lot of software involved
2. "Cell phone usage alarm"
3. Bearing and timing belts inspector, could let you know before parts fail

Jason go it, data logging for the press cycles. It measures when the carousel goes up or down and logs it to the SD card in CSV form. This is the second version with a larger box with space for a battery and to install the additional sensor connectors (8 connectors, one for each arm). It will take Ultrasonic movement sensors and IR temperature sensors to tell me which heads are printing or flashing during the job. The idea is to see how fast different color jobs print and how long it takes to set them up.
ultrasonic sensors measure the speed of sound waves so it would not be precise enough to measure the EOM. I think a properly calibrated Hall sensor might work for that, but we already have an EMO meter so not going to do that. I am looking into a FLIR sensor for the dryer (something Steve should be quite familiar with!), but it seems to be cost prohibitive. No shirt sensor will not work on an MHM as there are no physical interfaces I can tap into and tell the press to skip (S-Types and bigger have the button that we don't have). If there's time, I'd like to build an ink and platen temperature monitoring station or a ink temp sensor to install in the flash unit. . .

I have a lot of those fancy "FLIR" sensors and a lot of code behind them!! I might have some other cool sensors that could help with your concept..... Long beach 2017!

will be there!
Do you have anything that would read UV around 400nm?
pierre
-
Yes I do, it has an upgraded aperture to breakdown the light output by spectrum from 200nm - 600nm.

WOW! Is that a sensor or a meter?
If it's a sensor, where do I get one?
pierre
-
It is a sensor, I needed it to measure up to 16 w/cm^2 without washing out. The software will display a real time graph of all of the wave lengths being produced by a light source. Where I got it, and had it customized is a different story for a later date!

It shocks the operator when they shut the press down with no apparent reason!!!!
Is that it????
-
Did you build it Pierre?
I see Arduino ultrasonic sensor but those are just "commonly used for..." sensor breakouts and could be used for anything.

yes, it's Arduino based . . . cheap and easy to set up.

That would be the best tool ever.

Neat. So in the USB mode it's like a flash drive?
You use a RTC module, or does it fake time from the clock?

not working as a flash drive, only an SD card for logging. There is a way to reprogram the Arduino to make it do that, but it's beyond my current (starting) skillset. I am thinking about making it Bluetooth as am not certain of the security issues with WiFi on Arduino.
Yes, it uses a real time clock (RTC) module so it keeps track of dates (needed for the data analysis).
