Re: [CAD_CAM_EDM_DRO] PIC DRO

I thought it would be a good idea to post how much a PIC based DRO would cost if you built it yourself. These prices are in USD as most on this list are of that flavour.

I have worked and listed the costs as per axis except for the common parts that only have to be bought once and it all refers to what I wrote in the orginal posting of my wish list. The items list are by no means definative as it relies on someone else doing the PIC programming and designing the circuit. I will be glad to do the metalwork and the artwork for the boards.

The prices quoted are for one off quanties or small amounts from the likes of Digi-Key or USDigital.

Common parts are the power supply which is about 1amp @ 5v. I think this amount of current is enough for our purposes.

Qty. 1 Box 6.36 HM112-ND
Qty. 1 Transformer. 9.63 MT2104-ND
Qty. 1 Bridge Rect. 0.52 RB151MS-ND
Qty. 1 Cap. smoothing 16v 6.800uF 2.45 4209PHBK-ND
Qty. 1 Heat Sink TO-220 1.75 HS239-ND
Qty. 1 Voltage Reg. 7805 0.75 296-1974-5-ND

Misc. items such as circuit board, stand off's, screws, cable?


The following should be seen as per axis eg. if three axis is required then multiply by three. Some of the costs are not known at this stage because I have no idea what metal costs in the USA.

Qty. 1 Linear encoder 27" long 54.00 13" long 26.00 Rotary 2000 line/rev 5/8" bore 22.00
Qty. 1 HED****** 360 line/inch 25.00 HED******* 2000 CPR 28.00
Qty. 1 Up/Down Counter LS7166 11.65
Qty. 1 PIC 16F877 11.95
Qty. 1 Display LCD 12.88

Misc. items such as metal to protect scale, circuit board, stand off's, screws etc.?

This is a big difference in cost over commercial made systems @ $1000.

Regards,

Terry.
