Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- Adult content is not allowed. This community aims to be fun for people of all ages.

I keep those but convert their use to replace disposable battery powered devices.
All those spare USB wall warts you have are 5 volt and at least 1 amp DC power supplies. Anything you have that takes 3 AA or AAA batteries is a 4.5v supply. Almost all of them can tolerate the extra .5 volt. Clip the mini-USB/micro-USB/classic iPod/lightening connector off the cable and run those (I usually solder them) to your device. Now you can plug it into the wall and never have to worry about batteries again.
6 volt DC wall warts can be used to replace things that take 4 AA or AAA batteries.
Yeah but what about those at 7.2v or 12v or 17.8v?
Also maybe I'll save someones life with that old 100MB Zip drive (and power block)!
12v are great for "car" accessories.
