@ Mannar, Sri Lanka
Name : Indian Roller
Binomial nomenclature: Coracias benghalensis
Status: least concern, resident
A common breeding resident in dry lowlands, uncommon in other parts of the country. Seen in open areas solitary or in pairs. With it's light and dark blue wings, it is extremely colorful in flight.
December 2012 was extremely rainy in Sri Lanka, even in usually very dry areas like Mannar. I was utterly disappointed as it restricted travel during the holiday season... but it opened up some good opportunities like this as well.
Roller Derby: Dolly Rocket Rollers vs Glasgow Roller Derby at Loughborough Leisure Centre on Sunday 28th April 2019
Not so interesting or material this week - need to write the software for the die roller. Though electronic component fiddling does resemble playing with Legos, microcontroller-based projects also have a programming side that needs to be done and in which I am more at home, being a long-time software guy and a novice hardware engineer.
I'm pretty busy this week, too, so I doubt I'll finish it today, but it shouldn't take long.
In case you were wondering, this is what the software development environment for the Microchip PIC microcontrollers looks like, if you develop in assembly language. Details on request. This is a slightly weird angle on it, since it is a Windows program and I'm running it under "wine", which is a pretend-Windows environment that runs under Linux. It's a little bit hiccupy that way but lets me do the typing and some testing. I haven't tried actually sending the program to the chip from this Linux laptop - I use the tiny Windows netbook for that since it fits handily on my cluttered hobby table - but I like the Linux machine for the software part since it has a much bigger screen.
The reference to "Nigel code" in the comments is due to a now somewhat dated but still live and useful PIC Tutorial site by Nigel Goodwin. It has several useful examples of applications of the PIC chips, from which I've cribbed a fair amount for some of my projects. Its attached forum shows activity as recently as last August but mostly it went dormant around 2006. Great site for beginners even still.
