Click For Summary
To convert a $10 WiFi unit designed for 120V AC to run on a 12V DC car battery, it is necessary to determine the DC voltage output from the unit's internal AC supply. This may involve opening the unit to access its components. A fixed voltage regulator can then be used to adjust the voltage to the required level, whether that is 12V or 5V. Alternatively, inexpensive 12V inverters that convert DC to 120V AC are available for powering the unit directly without modification.

I am getting one of those $10 WIFI units from china runs on 120 volt AC and I want it to run off of 12 volt DC car battery I am thinking will need to open up unit and try to figure out what the DC voltage is that is coming from the AC supply unit and then insert a fixed regulator of 12 or 5 volt or whatever the DC voltage may be.

You can buy inexpensive 12V inverters that produce 120 VAC. Will that do it for you?

Thread 'How do I fix a hedgehog enclosure that keeps getting too humid'

Hey folks! So I’m kinda losing my mind over my hedgie’s setup lately. No matter what I do, the enclosure keeps getting super humid and it’s starting to smell funky. I clean it, switch bedding, crack the window, the whole nine yards… but it still ends up damp and I’m worried it’s gonna mess with my little dude’s health. I’m starting to feel like I’m doing something wrong even though I’m trying so hard. Has anyone dealt with this before? Any tips, hacks, gear recs… literally anything would...
