Frustrating but fun

Circuits Wild.

Dave Frederick

Thanks Big Clive. I didn't know that about the pins. Do you think shorting a couple of the pins would have duffed the system? Wild.

Dave Frederick

I've still not opened the "scent" packet that goes into the discarded front grill thing.

Dave Frederick

If the other one sucks too, I might have to figure out a switch to go from bright, lower and off or something.

Dave Frederick

I still like it. The light is amazing and really kind of diffused so nice illumination really. The breeze is sweet.

Dave Frederick

Ahh. Thanks. I ordered another one to see if it works better. LOL

It used to be worse and was definitely a Winter thing. Partly because of the heavy outdoor work I did back then.

Big Clive

Gaud. I hate that. Usually that happens for me in the winter and seems to be tied to dryness and my own hydration. Or at least that's what I tell myself.

Dave Frederick

Geeze, I am still sort of hop scotching through the color bands as it were. Thanks. Much more to learn and learn again.

The infrared receiver with three pins is designed to receive modulated infrared and then just supply data. So it has two power pins and a data pin.

An update on the one I got which was one that had both warm and white LEDs supposedly with the ability to "tune" between them, turn them off and other super duper functions like fan only and dimming with a remote and everything. Turns out all of it is totally flaky with the remote. You can't dim them for anything and with continued button pressing, you can sort of tune the color balance. Forget turning the lights down and or even having just the fan. Overall though, I hung this thing slightly behind me and over me and I really like the sort of soft but very bright light. The wash of air is nice and will come in handy when it gets much hotter here and I want to keep the AC at a minimum. I'll keep it and use it but still, the other features of the remote would have made this thing gold! I live in Idaho where it's at least a dry heat but will be looking at well over 100 degrees (40 C) in a month or so. The circuitry of course, as I guessed, is much different. Three transformers, no clipable resistors (there's three wires going to the circle to utilize both a warm and cool LED pattern of LEDs) Guessing there's more circuitry to go to the IR receiver. That component, little dark smoked led looking thing poking down behind the blades had 3 wires? (two of which were shorted when it was put together by accident and sort of crimped and touching) I would have thought the receiver for the remote would have had two wires? Wondering if the two of them touching/shorting when I powered it up fritzed something? Mostly, I wish the PWM or dimmer would work. It would be nice to have it more ambient as the night rolled on. The other side of the circuit board in mine had nothing on it as well. A death beam cap folded over and nothing but surface mount components and ICs. I didn't take pics of the circuit board but otherwise, a similar build. I could do that pretty easily if you'd like to see it.

It just sees a sudden loss of the supply to detect that it has to switch modes. Either pole can be interrupted.

Big Clive

Cracked skin on a knuckle that kept cracking and then caused a full on flare-up in its vicinity. I think it's gradually returning to normal now.

Big Clive

Yeah, there are many more Chinese datasheets than translated ones. I guess that their biggest market is Chinese manufacturers by a huge margin.

Even official site don't have full English, fun! http://www.bpsemi.com/en/col598/1317

It is a bit squirmy.

Strange design! I wonder if un-screwing and re-screwing is the exact same as using a switch to kill only the "L" or "N"

Re fusable resistor: I was of the impression that the black fifth band indicates a wire wound resistor. A fifth white band indicates a fusable resistor. In this case, the 3rd gold is x0.1, the 4th is tolerance. Can this be the case?

Rectified mains (minus LED drop) between two pins of a SOT23-5 sounds like a recipe for tracking.

Nice Big Clive. I've been looking at fans similar to this on Ali. I have wondered if they actually put out any air as I think it would be refreshing to have that over me at my desk. Now that's confirmed so I bit the bullet as it were and ordered one. The one I ordered apparently has dimming, color temp and timed functions with a remote. The On/Off thing would have been fine but at $16 and some change delivered, what the heck right? Guessing the circuitry is going to be a little different. I couldn't find pink but white will do.

Dave Frederick

Yay! We can customize the faults when we order the product! That's like programming in all your bugs so you know where they are when you take them back out.
