FWIW, chdkptp (https://app.assembla.com/spaces/chdkptp/wiki) should work with your A640 if you install CHDK (https://chdk.fandom.com/wiki/CHDK) on it. I've only tested recent chdkptp on Windows ...

Turning the screen off with CHDK  set_lcd_display(0) will almost certainly work, but likely won't save as much power. The native "display off" mode turns of the sensor between shots, while the ...

How are your recording timelapse? From the manual, I think the native timelapse feature only works in movie mode, so CHDK? If it's CHDK, what script, and is the script turning of the screen and ...

There are a few options, though depending on your needs, just getting a cheap USB webcam from amazon or similar might be the best one. 1) As Randy mentioned, you could use the TV out capability ...

You can get the Galilean moons without over-exposing Jupiter, but they'll be very faint and you'll need to boost the shadows in post to really see them. For exposure on the 300mm zoom I'd start ...

For very old cameras like this, you almost certainly need an actual SD card, not SDHC. SD cards are usually 2gb or less. 4gb SD cards did exist, but they were rare and almost all 4gb cards you ...

How did you copy the firmware file to the card? If you are using a Mac, there's an issue  sometimes encountered by people trying to install CHDK that can prevent the update from being seen ...

If you aren't already aware of it, you might want to check out https://www.diybookscanner.org/ which has a lot of information on this kind of thing, including using powershots. You can use CHDK ...

Mechanical shutter failure can cause symptoms like this. If recorded video and live view look normal, that would strongly suggest shutter failure. Shutter failure could be either electrical ...

Unfortunately, no video related functionality is implemented in the SX60 CHDK.

The "lock" tab on the card is just a piece of plastic, there's no electronics for it on the card. Instead, the card slot in the camera has a small switch that engages with the lock tab, and the ...

FWIW, there's a CHDK port for the original (MK1) G7 X. It's in the 1.5 development branch, but it's plenty stable enough for normal use.

AFAIK, auto focus on these cameras is closed loop using contrast detection, so it's not clear to me what kind of simple adjustment would make the difference between working and not. There is ...

Most PowerShots do not support using HDMI out in shooting mode. Exceptions are relatively recent models like the G5 X. Your SX30 only supports using standard definition analog video, with adapter ...

I don't have this specific camera, but in my experience most PowerShots behave in a similar way: If you hold the shutter down in continuous drive mode (set in the func menu on sx530) it shows each ...

These cameras do not retain the manual focus setting when you restart. As you've noticed, older cameras like the A590 also exit MF when the camera goes into display off power saving mode. There is ...

I'm pretty sure the SX540 does not support USB charging. Generally, the modern PowerShots that support USB charging have micro-USB plugs, where SX540 uses the older mini-USB. (This is not to say ...

It's likely that the battery for real time clock has died. See https://support.usa.canon.com/kb/index?page=content&id=ART118787

A user in the CHDK forum has posted some impressive results with a lot of information in: https://chdk.setepontos.com/index.php?topic=13638.0 Despite the thread title, there's closeups as well as ...

Yes, sx540 is more similar to your sx30 than the sx420 was. Weight is a bit less, 600g for the sx30 and 440g for the sx540. sx540 also does not have the swiveling screen. It does have manual ...
