I had an interesting meeting at lunch time today… Ended up taking three hours… Really really interesting. It will be interesting to see what happens out of it… This was at Vardy’s on King Georges Road at Beverly Hills. I have finally paid my $3 for a Vardy’s card – after all I visit a few times a year.

Now that my program on the PIC processor is actually compiling and uploading I am actually getting some work done on the program. And the bugs are being removed. I have having to re-learn some maths – SIN, COS, TAN and their inverse. I have not needed to seriously use them for some time. And i had to remember if the ratios are before or after the function. Is it COS(x) = A/H or is it COS(A/H) = x. It is the former, but it took me some time to work that out.

I needed to work out an angle was 45 degrees +- 22.5 degrees without using trig functions, but with northing and easting. I got around this by working out that if the numbers were within 50% of each other then it would be within about 19 degrees which was close enough.

Right now I need to get back to the hardware. I am working on the plane tomorrow, and need to visit my grandmother for her birthday on Sunday…
