Servo Buddy Beta - General Discussion

Saw it on yt and decided to get one. Now sold out.... can anyone confirm if I got 50/50? Im in FTC robotics so this guy will come in handy! Already started working on code to make it program servos too!

Hello all. I am owner #45, it arrived today. This is a very nicely 3d printed device that I hope to find some use for. I was drunk surfing YouTube shorts after the New Year and for some reason this device popped up in my feed. Being an old school electromechanical geek, I thought it was neat but swiped to the next video. After seeing the short again, I found the full video on what this thing actually does in detail. I decided I needed one even though I really have no use for it. I might go down to the local hobby shop and see if I can buy a few cheap servos to play with. I did find that licking my finger and touching all three pins does simulate a servo and I could change angles.

I hope this beta program goes well for you and I'll try to contribute once I get some servos.

LOL this is great! It sounds like something I would do... 1. buy something unique, just because it's unique AND 2. Test it by licking my finger.

Sorry maybe I wasn’t descript. I ordered one earlier today and right after saw that they were sold out. I am just wondering if i managed to snag number 50/50 or are they no longer the numbered ones being sold?

ah i see 😔 I bought the prototype not the beta :(
 
What’s the USB-C port on the bottom for? Software updates? Not seeing any info on that yet here on the forum or the videos.
 
I would replace the button with a clicky encoder. that would make this product perfect physically imo

That is for programming. It's not something I intended to make available for the average user. Feel free to hack it if you want :)
 
Has anyone tried with an EDF? I get this error. 80A Skywalker, 70mm EDFs. Tried with my 'old' servo tester and it works fine. Ideas?

Update - mine does not work with any ESC. I get this error with any ESC I plug into (battery plugged into ESC, esc connected to motor)

Yes. Working for me. 70mm 4S fan with an e-flite 70 amp ESC. Although it seems to be spinning the EDF at much more than 10% throttle.

Did you are plug in a battery to your ESC?
 
Yep - battery plugged in. I changed nothing other than servo tester and it spun up with the old school one
 
This thing rocks for building! So easy to grab a servo wire, not worry about orientation, and just plug it in. Easy to use because it's just one piece. Great to assure a servo stays centered while gluing in a control horn or making control wire. I put a Y on it for ailerons and separate elevators on the FT F18. Also very handy to figure out which servo wire is which before plugging into receiver - quick plug into each wire, bump the servo, plug into the receiver. The more I use it the more I like it just like it is
 
Any consideration for making it rechargeable most lithium batteries have enough energy and incorporating a charging circuit wouldn’t be too difficult

Love my prototype version of the Servo Buddy. Been using it as I build 3DSETS RC models. Only issue that I ran into so far is that it seems to have reboot issues when using it with DS3218 MG DSSERVO digital servos. Maybe current related??

Thanks for the update!
I believe you are correct about larger servos drawing too much current. It’s not ideal, but you can power the Servo Buddy with an external USB-C power source. This should provide enough current for larger loads.

Hey Chad, i tried to power with external USB, remembered seeing that in one of the videos, but still had the same issue. Display would wig out and reboot. At one point I lost the screen was worried that it fried so left it off for a bit then tried it again and it came back up.

Ok - that’s good feedback. I’ll get that exact servo and do some testing for the final.
