There's a similar post out there about converting a battery powered baby swing to run off a dc power supply but since I'm not sure if it's cool to hijack someone's post I just started a new one.
Here's the link to what I'm trying to do: Russelldad's blog: Guest Post: Baby Swing Batteries/Plug...
Hello all, just wanted to put an end on this thread by reporting that the fans work as intended. They don't get the room up to 80 degrees like the room where the fireplace is but they DO get that back room warm enough so that my wife doesn't start shivering when she walks back there or jumps in...
enjunear - Good idea about the fuse - I hadn't thought of that. The fans are very quiet so no worries about noise, but they may not move the air enough air even if left on all day as I plan to. I'm just going to install it and see what happens. :)
dv_sa559 - Regarding the strength of the...
Finally got the thing together with hot glue and zip ties just so I could test the concept. It's not pretty but it powers up when plugged in and moves air in the right direction which is all it needs to do. Now all I need to do is cut a couple holes in my wall and see what happens!
Since the...
Guys - I don't have a power source that puts out AC power except for my wall plugs and I'm not comfortable with hooking this thing up to my home power just yet.
I totally appreciate all the help with this question but it doesn't sound like this is the transformer to use for a first timer's...
I'm not sure I have a power supply that puts out 12v AC. 12v DC is no problem but 12v AC isn't something I have laying around I'm pretty sure.
Alah - you say any 12v transformer will work... can you please expand on that in case I have what I need and don't know it?
Raza - I get tone when I check for continuity across all three thicker wires, meaning I can touch any two of the fat wires and get tone. When I test for continuity between any of the three fat wires and the thinner ones I only get tone when I test between any fat wire and the thin red wire...
I have a multimeter and know how to measure resistance... that's something at least. Since I'm not sure which red and black wires you're talking about (I've got two of each) I just measured as listed below with my meter's dial set to 200:
1) Fat red to fat white - .3
2) Fat red to fat black -...
Thanks for the input, but before I do anything with the transformer itself I'd like to know if the numbers printed on it mean anything. Based on the size and weight of this thing and the third input/output wire I'm guessing this isn't a good candidate for a power supply built by a noob. :)
6 wires total. I've got three heavier gauge wires with identical connectors - red, white and black. There are also three smaller wires (also red, white and black) that go into a single 3-pin connector.
Alah - I thought the small the gauge the heavier the wire?
Can anyone with more knowledge than myself tell me, based on the numbers printed on this transformer, what the specs are? I'm looking for something with a 24VDC, 2A output for use as project power supply but I'm thinking this is way bigger than that. The numbers printed here are the only ones...
Thanks very much Santosh and Qaisar! I'll see about finding the parts laying around the house here and post a pic of the functional device.
Thanks again!
Yes, fans are DC.
As for the power supply, do I need to find one whose output exactly matches the input of one fan? What specs should the power supply have?
I use wood to heat my home and need to move the hot air from the top of one room down through a wall cavity between studs to a vent near the floor in an adjacent room. Here's a commercial version of what I'm trying to accomplish via DIY:
I would like to connect the case fans to a standard...
