I made a cheap DRO for my CJ18a mini lathe using 4 cheap Aldi workzone digital calipers, an interface using an Arduino nano and a cheap Android tablet running the TouchDRO app.

I have intended to post about it for a while and todays post about cross slide dial calibrations on the same lathe has prompted me to actually do it.

I can’t claim any originality in this – I have followed ideas from various others on the internet and based the circuit on the one posted by Les Jones on here.

I think it cost about £80 in total.

I am quite pleased with it as a beginner.

Photos in my Lathe DRO album.

Hi Stuart,
You may get more "traction", if you link the photos from your album into your post. Use the camera icon in the editing menu bar
