Today I drove the Land Rover back up to Bracknell via Salisbury plain. Alan kitted me out with tools and loads of gear, such that no matter what became me on the trip, I would not need to use my AA cover. I glad though that I didn’t need it or the tools.
Cruising at what appears to be 40 mph and 2500 rpm, in reality thats closer to 60 mph.
I drilled all the holes into the PCB board last night, using a regular sized cordless drill and my tiny drill bits. I held both items, one in each hand and was able to drill all the holes without much trouble.
Today I etched the PCB board using ferric Chloride. It worked a treat, but probably showed that I should have cleaned up the board better and taken more time and had more patients when doing the ironing of the print. Either way it has worked and I now have some tinning solution in the post so that I can coat the bear copper with something to making soldering to the board easier and also to protect the copper from corrosion.
I printed the circuit onto photo paper and cleaned the PCB board using a kitchen scrubber thingy, brand new. I then ironed the print onto the PCB board, I don’t think I ironed it for long enough or hard enough, so I wound up spending my evening colouring in the blackness using a Staedtler Permanent marker pen as supplied by the etching solution people from Ebay.
We didn’t get up to a great deal over the long weekend, we did have Lynn and Gerry to visit on Friday and on Sunday visited Portsmouth where Hannah cooked a great roast! We visited Basildon Park (NT) on Saturday, which was pleasant but busy. Mowed the grass and kept busy around the house the rest of the time.
I started to design a printed circuit board for the shift registers to expand my Arduino board on Monday.
