homemade pico switch

[super mud]

I don't know if anybody else does this but relized I could make a pico/relay switch out of the circuit board from a servo. I just made an led bar so this helps with testing it. I just took out the motor and pot and wired the pot leads with 2 2.2k resistors and shortened the board and soldered my led leads to where the motor leads were. "thumbsup" What are your thoughts?

Heres a crap video if u wanted proof

very cool man "thumbsup"
nice to see more home made things

That is pretty cool, guess i'll have to stop pitching the junk servos now. Better then paying $20.00 a pop for a pre-fabb'ed one.. "thumbsup"

Been there, they also make good replacements for 3R winch boards "thumbsup"

I'm using this servo mod for a year and a half to switch leds, winches and more on the cars. It works perfect and, that way, we recicle old/broken servos:mrgreen:

It also can be used as ESC for "small scales" like X-mods.

I use the servo case to give extra protection and it can be mounted like a servo just about anywhere.I have probaly made 40 or 50 of these so for and everyone loves them.But it is a good way as mention to reuse old servos.

how much for the ouput voltage from servo board?

I'm runnin 6v. Thats usually max volts on a servo. It might be possible you could run more but idk. I dont kno what craps out first from over powering. All my servos die from water lol.

this works so slick i built one last night but i left th pot in to try it it works so cool thanks for the info

No doubt, I've got 8 or 9 crapped servos laying around. I'm glad I did'nt pitch them now. Cool idea...

so dumb question(i know) but what is this exactly? like I see a LED lighting up but I'm not sure whats going on? I have a servo that is out of commission?

It's a radio activated switch. It can be used for many things but with the LEDs, you can turn the lights on with the same radio that you drive with.

ok i made one of these but let the pot on, is this why my whinch slowly lets out line or sucks it in as a drive?

if so could you add a bit more detail as to where you soldered the 2 2.2k resistors
and that is the only changes you made?

The resistors replace the POT

My apologies for reviving an old thread.
What's the use of the resistors?

If the servo doesn't reach the end because there's no motor wouldn't it just keep supplying power to the motor voltage points?

I found this gem of help the other night thank you for the how to I had not idea. I made one yesterday out of a old servo for my 3r winch but it still walk a little and I am not 1005 sure where to solder in the resistors my pot has 3 wires coming off of it. Thank you guys for the help.!

so you are using one of your channels to turn your trucks led's on and off as you drive then....what radio are you using and how many channels, us guys with 3 ch radios can't waste that 3rd channel........bob

I use mine for my trucks LEDs and I'm using a Spectrum DX3e

I did that 3 years ago:ror:

I diden't change the resistors, I just glued the pot after finding the sweetspot where the light was brightest and no flimring...

Still work after 3 years of use"thumbsup"

Bumping this old thread because I know tons of people have to have old servos that would be perfect for this. I know I do.

So with this hack, do I need a LED control board at all, or no since the servo has a pot/resistors already?
