Unless your main workstation is a laptop, you’ve probably got a APC or similar battery backup kicking around. But have you ever thought of modifying it to make it a bit more useful? After all, it can be used as a useful DC power supply…
[The 8-Bit Guy] shows us how he modified his APC to include a voltage readout, and direct DC output jacks. As it turns out you can get a lot more battery life if you’re not using the built-in pesky AC/DC power inverter! Stick around after the break for a very informative video on how he did it.
Of course you don’t need to start off with a consumer uninterruptible power supply. We’ve seen DIY systems put together without breaking the bank.
