Power sliding window..again

Its from a Honda and needs to be trimmed a lot the while regulator will not be used just parts of it. This will mount to the back panel behind the double cab boxes. I still need to make the whole thing but think I found one with will work . my plan is to do this on the side and sell them. I have 4 switches right now 2 that benwa linked which are the exact ones that I pulled from a landrover from the junk yard. My plan is to make a template and do measurements so that one can measure it out place the template and mark the holes. Use self tappers to attach the cable rounds and then supply a bracket for the motor to mount to.

 

Tonight's update, the threaded rod is working great, but as I print it in finer and finer resolution it became easier to force the window open from the outside. So I'm trying again with a much more aggressive pitch and going back to the 800RPM motor. This should still keep me in the 4 second open/close range and allow the window to stay locked shut. Iteration, I do lots and lots of iteration.

 

I'm good with 4 seconds, Make It Happen Captain!

 

This has been brilliant to watch the work and care you put into this project. It's a fun watch and your work is great.

 

Great progress!!!

Have you thought about some sort of electrically releasing latch assembly instead of relying on the motor stall to keep the window locked? I'm imagining a lever like contraption with a simple electric pull solenoid that locks over the window side bracket, similar to how the OEM window lock latches. Maybe I'll try and draw it up later tonight...


Side note: I got bored tonight and spent about 30 minutes writing some Arduino code...

I know you mentioned you might go the relay route. I'm going to "borrow" a lot of your 3d design work verbatim but will probably still go with the Arduino (I've got a ton of them lying around, might as well use them).

I sent a pull request on github with the code I wrote if you are interested. It seems to work as expected, I'll be doing more bench testing tomorrow just to make sure.

 

Thanks Other members ideas and contributions have kept making this thing better and better. I would have been done a month ago and just running the threaded rod, but some really solid stuff has come out of here. I think we're in the home stretch, just tweaking a few things now and it'll be done soon.

 

100% open source and free to do whatever you want to with. I've pulled in your code, really excited to have it in the repo!

The only way I came up with to do a drop bar and still be 0 modifications was to do what was essentially a servo arm that rotated a bar over 90 degrees from horizontal to vertical. Lots of problems with that though with mounting methods, making sure the bar is strong but light enough for a small servo to move, etc. The good news though is that with the pitch correctly set on this lead screw, it acts just like a security bar.

 

I'm not sure if this will help you any, but if you short the two terminals of a permanent magnet motor together (when it is not running) it is very difficult to get it to turn. This acts as a brake and could be used to secure the window.

 

I did some bench testing of the Arduino code tonight. Submitted the updates needed in a new pull request on github. Check it out all hooked up and running with 3d printed lead screw and everything:

if anyone decides to make and sell any of these power slides let me know

 

I swear to god you are reading my build book when I'm not looking. I'm toying with having a 3rd relay that shorts out the motor contacts when the motor isn't moving the window, assuming that this last print I'm doing right now isn't what we need.

 

So awesome. merged in your changes and did a commit on the lead screw. I'm going to be a little delayed for the next few days with some travel for work, I'll try to get to the commits but I just went ahead and added you as a contributor so you can push your own if you want.

 

Does anyone think it was be possible to use a power antenna motor. For the power for the power sliding glass???

 

might work, I don't have access to one but what we are essentially making here is a linear actuator. Do you have a picture of one?

 

no I don't.. I am not smart as you guys to make one.... I wish I was tho

 

Sub'd!

 

I plan on doing this once a complete kit gets worked out. I love the progress that has been made and like the idea of adding something that requires little to no modifications.

Already talked with scratch, not looking to make any profit just willing to put the time in to bulk order and assemble kits.

 

love this thread. hope ya'll come up with something simple. i'd love to have my rear window power opened

 

The security bar issue is taken care of. I found a good pitch that isn't forcible and is still fast. We are going to need to bump back to the 800RPM motor to keep movement under 4 seconds, but looks to be working. I'm traveling a bit for work over the next week or so, but when I get back we'll be trying out the new gear on the window.

 

Don't confuse smart with not afraid to fail in public

I found this on google, and it looks like the antenna works like a bowden tube just like the regulator motors folks are using. The only rub would be that this looks considerably larger than the regulator motor and might be harder to mount because of that. If anyone wants to try though, it seems like a viable route.
