electronic.
|

|
|
It is hosted by Ken Fallon and in about 5 minutes long and Karina Cleanflag.
|

Hi everybody, my name is Ken Fallon and you're listening to another episode of Hacker
|
||
|
|
Public Radio.
|
||
|
|
Today I want to tell you about troubleshooting a model village Windmill that stopped working.
|
||
|
|
We have a Christmas.
|
||
|
|
One of the original ones was a Windmill that went to Blade of Water and it's a Christmas
|
||
|
|
thing.
|
||
|
|
Anyway, this year it stopped working all of a sudden and which is an external power supply
|
||
|
|
and a battery supply so I was kind of dreading taking it apart because I've tried to fix
|
||
|
|
a few of these things before and they are built.
|
||
|
|
They're built to a price I think is the word we're trying to say here.
|
||
|
|
There's no standardization, cables, power might be, you know, positive might be white, red,
|
||
|
|
blue, green, even switching colors from one LED to the next so you can trust nothing
|
||
|
|
in there.
|
||
|
|
An absolute mess of wires all soldered down onto a little.
|
||
|
|
What they had reused was a male USB header which has got a large earth and then four
|
||
|
|
different pads and they had drilled into that and put some diodes and all sorts but it's
|
||
|
|
a mess trying to figure out where things are going cause.
|
||
|
|
So you have a motor up at the top that turns the windmill around then you've got the LED
|
||
|
|
lights on the blades and those two come down as red and black which is fine and then there
|
||
|
|
are some LEDs hot glued around and that's another thing they love hot glue.
|
||
|
|
These things are just made with hot glue and then dangling wires.
|
||
|
|
So these wires coming down then all join together on shielded just a white wire turns into
|
||
|
|
a yellow wire that is insulated and goes to this little circuit board.
|
||
|
|
It is the weirdest, I have no idea why they did it like that but only trying to trace
|
||
|
|
it out I was trying to basically reverse engineers very difficult because all the wires
|
||
|
|
are not in to each other and everything so what I tried to do was do another piece of
|
||
|
|
paper and that didn't work, didn't have enough space and things moved around so I remembered
|
||
|
|
a two called Fritzing which is a F-R-I-T-Z-I-N-G or F-R-I-T-Z and it is a Fritzing.org and it's
|
||
|
|
kind of cool because you can put stuff on a breadboard, design stuff on a breadboard
|
||
|
|
and then you get the schematic and then you get a PCB of the thing that you're doing and
|
||
|
|
you can drag and drop in components and basically so I found this actually extremely useful
|
||
|
|
for debugging this because you could put in a battery symbol thing and then connect the
|
||
|
|
wires up to a resistor that over to the thing and as I was doing that I could disassemble
|
||
|
|
the various different parts and label them and eventually figured out what the circuit
|
||
|
|
diagram was actually quite cool it's not bad it's got a diode pretty reverse so if the power
|
||
|
|
supply is positive then that's cheap but cool so in the process of doing that I was able
|
||
|
|
to strip everything out so that break LED lights and the blades of the windmills were
|
||
|
|
working the tower were working they were and then the motor was as I did that as I connected
|
||
|
|
it sparked against the side of the battery so I'm deducing that that was broken and when I
|
||
|
|
connected up the power supply instead of reading 4.5 volts on it it actually read 7.5 so
|
||
|
|
don't know that might not have helped either so I promptly cut off the lead of that and chucked
|
||
|
|
it in the bit and I disconnected the motor as well from the whole thing because yeah it's in a
|
||
|
|
injection-wolded mount which is in the tough the whole thing with crack and break so right now
|
||
|
|
it is working on I reconnected everything up safely solder them and fixed some issues with this
|
||
|
|
that was their hot looped everything up and she's ready and by the time you hear this it'll
|
||
|
|
probably be back up so um tune in tomorrow for another example
