    Interrupt Driven Rotary Table controller

    Hi folks, at the risk of necroposting : regarding the problems that Edgar/reloader has been having... "...to know its bug free now. " Bloke I used to work with used to say "There is always one more bug!", and so it is with the RotaryTable11 sketch: So trying to change the Step pin will never...

    Arduino Rotary Table for Dummies

    I have a silly question: do you really need a graphic LCD? Or is it just for the challenge? Aside from that: generally when I'm trying to get "new" (to me) hardware working on Arduino, I start with a demo program - either one that cam with the libraries or something self-penned, but simple...

    Arduino RPM Application for Sieg Lathes and Mills

    Not sure if this is of any interest to anyone, but: my latest version uses a 4 digit LED "Digital Tube", with my adaption of the original code from MacPod/Jeffrey Nelson on an ATtiny84 piggy-back board. Using this, I only need to mount the display somewhere, and attach one cable to either the...

    Arduino RPM Application for Sieg Lathes and Mills

    Not too young to remember nixie tubes, unfortunately! The "Digital tube" that I used can be found on eBay by searching for "D4056A". Please be aware that this display is _not_ going to work with Jennifer's sketch which is posted above. It needs a different arduino library.

    Arduino RPM Application for Sieg Lathes and Mills

    Hi again Jenny, Regarding the name "digital tube", it's a bit misleading! It's just what the chinese ebayers call the 4 digit LED display. I've no idea why, as it's simply a 4 digit LED display with a TM1637 chip to make it I2C addressable. I guess it's intended for use in a clock, but in...

    Arduino RPM Application for Sieg Lathes and Mills

    Hi Jenny, I did a similar display for and SC3 (and SX2P mill) and shared the design with a YouTuber called Andrew Whale. Here is the video he did about it: Both of us used an Arduino Nano (clone) for it's small size, and a 4 digit "Digital Tube" display; but otherwise similar to yours. I...

    Mini Mill X/Y Tram and Gas Springs

    Hi Dennis, I haven't actually fitted mine yet. The design I'm going to use is based on this: http://www.rysium.com/projects/189-mini-mill-modifications This design also uses 30lbf struts. How did you arrive at the 20kg?

    Mini Mill X/Y Tram and Gas Springs

    Hey Dennis - You should be able to get some suitable gas struts in Australia from eBay, or StrutsAustralia.com.au or GasStrutAustralia.com.au I bought a pair recently from eBay (seller: "aussie_living") for my Sieg SX2P. The McMaster-Carr strut model mentioned above provides 15lbf each, 30lbf...
