Cheap Idea for a DRO

I'm in the process of putting a DRO on my X3. Given that a Yorkshireman has been defined as a Scot deprived of his generosity it prob'ly comes as no surprise that the reading heads for the scales will be these, at £2.99 a pop:

I've gutted 3 of these to get just the reading heads (ie no case, no readout, no battery) and replaced the batteries with pairs of capacitors to reduce jitter. They talk nicely to the capacitive scale strips I'm using (ex Wixey tablesaw DRO) so it looks all good to go. Readout is a Shumatech DRO550.

Please understand that all this is written with the unshakeable confidence of the totally ignorant. I know nothing about machining but I'm having enormous fun learning.

There are the same ones I bought ($US8) and seem to work OK with the scales I bought from Shars
They're spares for when I gut the original heads on the scales prior to mounting on my X2 mill.
