Division Controller

This post covers the electronics side of an add-on feature for my milling machine’s rotary table. A while back I saw the Division Master product and thought this was a great idea, however I had no intention of paying the £230.00 ($345.00) price for an assembled unit or £180.00 ($270.00) for a kit of parts to…

Binary Clock 5

I have recently been reading about the use of timers on AVR chips over at Max Embedded and thought this would be a perfect opportunity to update my binary clock once again. I decided to make use of the CTC option, whereby it clears a timer on compare, you set a value for the timer to…

DIY DRO for Mini Mill 2

I have since had some more thoughts on this subject and after counting the connections again, decided that it could be implemented with an ATtiny85/45/25 DIP 8 chip. After downloading the DRO_2_2 source code from Yuriy’s website and compiling it up noticed that it will fit on an ATtiny85 or 45, but not on a 25 because…

Binary Clock 4

I recently re-read an article, I had originally read some time ago, about an arduino clock source using a single wire, on Instructables by relic1974, and thought that this might possibly be a more accurate clock signal than the tone value I am currently using. The internal timer is not overly accurate and there seems to…

DIY DRO for Mini Mill

Having settled on some Igaging linear scales and Yuriy Krushelnytskiy’s DIY DRO for Android as mentioned in my Mini Mill posting I set about making the board itself a cheaper prospect. I am not a big fan of the Arduino boards and their associated shields, as they use a non-standard pin spacing from one side to the other, which is incompatible…
