Work continues on testing the PCB. Using a Hot Plate to solder the SMD components has been rather more difficult than I'd anticipated and only after three unsuccessful attempts have I got a working prototype. Getting the correct amount of paste on the pads and controlling the temperature profile with long reaction times to changes of temperature settings being the most problematic aspects. Maybe I should have invested in a Solder Reflow Oven but it's all part of the 'learning new skills' process.

I have not yet attempted to drive the Solenoid and still have to decide between the 12 volt Bacor with its position feedback and the 9V Claber as both have their advantages and disadvantages. Also on the 'list to do' is the revised layout of the PCB to adopt the necessary profile for the proposed modified Garden Lamp housing.

It's going to be a busy couple of months.
