Hi Gene, I found that site a while back, very useful.? The calipers they show are the very cheap ones which, I believe, have a different output format and are usually 1.5v.? The caliper I'm

Hey Julian, Are you planning to keep using the battery in the caliper? Wouldn't it be possible to hook up power from Arduino to supply the caliper with power, getting rid of the battery? A fresh 3 V

Happy to help! That's not too bad a plug - isn't fun working with such small wires? Thinking this through - since you have said there is a 3.3v and 3v supply, looking at the Atmel datasheet for Voh

Buffalo John, thanks for your reassurance.? I changed the sketch to make the "req" pin normally high and change to low,? hooked up the wiring and amazingly it worked, subject to some adjustments to

Hi Julian, nice to hear from you.Mini lathes are always difficult to add on mods due to space constraints.I cheated and used I gaging scales for reading Z saddle movement? and X for cross slide

Should be fine Julian

The 2N2222 is a general purpose NPN transistor and the usage here would certainly be voltage translation. However - is there a pullup resistor on the REQ pin? This can be checked with a volt meter

Thanks for the prompt reply, Mike.? But it's not really a TouchDRO issue. All I want to do for the time being is get numbers to the Arduino serial monitor to check the two will talk. After that Mark

Julian , ,I can't answer your question , but maybe you might try asking over on the Touch DRO forum over t Yuri's toys . ??? ??? good luck ??? ??? animal

Hi all, Been a bit quiet on here for a while, hope everyone is well. I thought I’d wake things up a bit by asking some dumb questions about a project I’m currently working on where my knowledge of

Well hopefully you luck out , if not take it apart & clean it again . ??? ??? animal

Mike That is something new to me. I just opened the scale and wiped it all clean. Now I have to wait and see how reliable it is.? Thanks for the idea-Prasad

If you can find one the old ShumaTech DRO-550 works well with the iGaging scales and gives you nice DRO features (like switching between diameter and radius on a lathe, basic math functions on lathe

The aluminium iGaging scales work great. For the price I would just go for it. Worry about the premium another day. Ralph

I apologize if I'm getting off topic. Reading https://www.touchdro.com/resources/scales/capacitive/igaging-absolute-dro.html begs more questions. From what I see Igaging has "standard" capacitive

I realize this started out as a DRO question, but in case you might want to go to CNC in the future... I started out with linear scales connected to a Mesa interface card into a computer running

Theres a guy that did that online somewhere , let me do some digging & see if I can find it . https://pcm52.com/tag/arduino/ ??? ??? here's one , but I know theres another one I was looking at .

Like the idea of the angular readout very much.? I'll have to sign up to see the details. I did look at doing something similar for the X axis ... Removing the magnetic strip from the scale and
