Tuesday 10 May - Programming - 6:00 - 8:00

Members will show the microprocessor assisted devices they are building, and help with programming problems.

Here is a summary of the April meeting:
Andrew outlined a project for testing water meters. It requires operating electric water valves rapidly many times at exact intervals, measuring the flow, and operating switches, counters and LED indicators. He showed the specification he wrote and an outline of a PIC12 microcontroller program for it.

Michael showed us three devices he built, an angle positioner, an alarm, and a LED array, all programmed for the PICaxe. To make a PCB he runs three separate layout transparencies through a laminator, so there are three layers of etch resist on the copper. This produces a dense pattern that does not need corrections.

Alex showed us a device he built for measuring and logging small variations in atmospheric pressure. It can be used as an altimeter. He used an Arduino Pro Mini, and Task Scheduler, a template for Arduino programs.

Friday 13 May - Friday Forum - 9:30 - 12:00

We will attempt to restore the Windows 10 operating system from the ISO image created last month.

Members to discuss their favourite browser, tool-bars, extensions, add-ons and stored favourite sites.

There will be time for Q & A plus general discussion as well.

Friday 13 May - Communications - 1:00 - 3:00
