You could put in green and white LED's wired to separate function outputs. Then you could determine the function when you dispatch the train. The...
Maybe they are playing 9 ball? Only the 9 is striped.
For that price it should include a working space shuttle.
I managed to put it back together, and learned more than I wanted to know about how its laid out. Thank you both for your replies.
I have the exploded diagram, and I got the tender reassembles, and everything else is back together, but I can't figure out how to reattach the...
I would suggest adding additional filter caps between the power and ground leads at the servo to reduce noise. Perhaps a 10 uF electrolytic...
If you don't mind working with SMD LED's, there are tri-color (R-Y-G) LED's available from Digikey or Mouser. The Kingbright APTF1616SURKCGKSYKC...
HO scale pins will be tiny. The dimensions work out to a height of 0.172", a base of .026" the widest part of the body is 0.055", the neck is...
That only works for resistors of the same value - the easiest accurate formula is the reciprocal of the sum of the reciprocals 1/(1/R1 + 1/R2...
Alkem scale models makes an etched brass kit for a 7 inch conveyor (http://alkemscalemodels.biz/industrial-conveyors/) , and Walthers lists a kit...
Now you need to decide between AMF and Brunswick pinsetters - and don't forget the ball racks for the house balls. Maybe include a pool table in...
If solder beads instead of flowing, it usually means the material being soldered is not clean enough - surface oxidation, oils, etc. Try lightly...
Its a good idea to try whatever stripping agent you are using on the inside of the shell first. That way if there is going to be a problem, you...
Reading through the Rev 2.0 users manual, it doesn't look like it has any current sensing capability. This will require external current sensing...
I too wish you a speedy recovery. I've been following your build thread with great interest.
Where did you get your full-width diaphragms? I've used the American Limited diaphragms but I haven't seen the full width ones.
The different colors of LED's are made by using different dopants and base materials, and consequently have different forward voltages. Red has...
The current through the resistor is the same current that flows through the LED. The resistor acts to limit the current. Using your example, the...
Sorry - i had a late-night brain fart. The power dissipation is voltage TIMES current (P=IE). 12.3 V * .02 A = 24.6 mW = .0246 W.
A more exact description of the operation of LED's is as follows: LED's, or any diode for that matter, have a non-linear current vs voltage curve....
