Adding lights to Swytch?

[andrewsh]

Hi,
I’ve purchased a Swytch kit, and as I’m installing it onto a bicycle that previously had a Shutter Precision dynamo hub and corresponding lights, I can’t help but feel that in terms of lights I’m getting a downgrade as I have to replace both lights with battery-operated ones, whereas there’s a huge battery which could power them as well. Has anyone tried to modify the Swytch setup to make it power lights as well?

Thanks in advance for any ideas or suggestions.

Personally I like having independent lights (battery leds in my case) with my much modified Swytch Mk 1 kit.

If the battery is a generic two wire connection, then if you have basic wiring skills you can take a 36V feed out of there, fuse protect it, and use a 36V to whatever voltage you need DC to DC converter and run the lights from there.

Some lights will work 12V-80V. I've got this one soldered to my ebike battery (two wires) via an inline blade fuse and waterproof handlebar switch. It's one less thing to forget about charging before going for a ride.

Hi,
Just in case someone finds this thread but not my blog post: I managed to get a set of Axa lights work with Swytch.

@andrewsh - I'd deffo cover that connection with self-amalgamating waterproof rubber tape, also available from Screwfix:

Pardon our interruption...

Those connectors are already waterproof, but yeah, why not.

I don't trust anything claiming to be waterproof, at all.

Extra large image editing

How often do you need to do something with extra-large images? Usually, I don't need to, but recently I've received one such an image, and really needed to crop it. That image was 21 MiB 16 Kpixel×12 KPixel aerial image in a JPEG file. As anybody knows, JPEG files can …Read more

Very handy. I was trying to crop an extremely large image a few years ago to make a lot of tiles from that one image, to assemble after enlarging and printing out, to cover a wall, to trace that image onto the wall, to then paint. Photoshop adequately resourced did it in the end, but jpegtran would do the same with a far less powerful computer.

Options are less limited with dumb batteries:
