So the little 590nm modified Powershot n finally came to a destructive end from mother nature and, on reflection, my ill-considered kite flying – I should have flown a kite more stable for bigger gusts on the day. We learn.
The lens took most of the impact and will now not extend or retract. I guess it could be repaired, but it is not worth it and I would like to change it for something less fiddly. It has been good as a light-weight flyer, but I have struggled at times, especially while holding the line, with the small touchscreen and CHDK settings.
Next, it is a Canon Powershot SX240, as I decided to continue using CHDK for access to RAW files and interval timer scripts; saving the weight of an external interval-timer unit. The SX240 is still light-weight, inexpensive to buy used and convert. It also has a shutter priority mode, unlike the Powershot n, which should help with swinging around on the end of a pendulum.
I looked at a few other compact cameras, like the Olympus TG (tough series) but could not find anything inexpensive to buy, with a built interval-timer that supported short intervals around 1-5 seconds and unlimited shots (until the card is full), which is what CHDK scripts will do. I also looked at using older GoPro models, which can now be converted for IR, however, don’t like the smaller sensor images and fixed wide angle – fly too high and the images are too wide losing detail.
The Canon A series (good optiA810, A1300-1400, A2300-2600, A3300-4000) are generally cheaper than the SX series to buy used and lighter, however, they don’t have helpful options like shutter priority.
Infraredy (the ever excellent and helpful Andy) are already converting the SX240 to 660nm and it should arrive for the weekend. I decided on 660nm just for something different from the Powershot n’s 590nm and did not want the more color-limited options of 720nm, 850nm etc.
