In response to my previous journal entry A Better Meal Worm Farm
, I have been asked how to actually make an exhaust fan for a meal worm farm. You geeks out there probably dont need help with this but some folks actually dont own soldering irons or have donor computer junk handy, so for them, here it is.
It took some creative searching but I finally found some usable product links to make this easy for you. All you need to do is choose any small computer cooling fan
that has the standard PC internal four-pin power connector as shown below, and then pick up a power supply
that has the same connector and that's all you really need. Im sure you can manage to figure out the rest. It is always a good idea to also cover the external side of the fan with a matching grill guard
to protect fingers or possibly curious sugar gliders.
You can use your imagination and cut this into your box any way you please. You dont need a large fan or a strong one, it only has to slowly remove moisture. Those of us with soldering irons, skills and junk lying around might even end up using a lower voltage power supply on these or install a rheostat so you can pick a speed that works for your install.
