in this video I'll be attempting to convert my standard dropper post to a wireless dropper post without spending a fortune, I'd say this project turned out nearly perfect but with some minor modifications this wireless dropper post could gain a permanent spot on my bike, seat back, relax and enjoy!!!

Very cool! Regarding having a low power receiver, you can have the receiver sleep most of the time, and wake every 100ms to send an "awake" message and then wait for 1ms to receive a message. When the transmitter wants to send something, it waits for the "awake" message, and then sends its own control message. This reduces the receiver current by ~100x, and only introduces 100ms delay. This is similar to how the ANT+ (garmin/etc.) low power wireless devices work.
Awesome execution! This would sell super fast if you could work out the kinks. Usable on any dropper is key. You should get a patent immediately. Well done!
Run wire through the bike frame from were you originally installed the dropper post wireless attachment to the handlebars. You could install a usb for the battery to change there. Just make sure the wiring is inside the bike frame and it should help
If you are going to have an antenna coming out the dropper cable hole, you could also add a charge port there as well.
well done. Great idea and execution! Could be great on a ebike where the receiver could be connected to the ebike battery. If you decide to sell the system let me know
Nice work! We’ll done sir!👌👍😉
well done, very good idea buddy you could make a great product with this. about the battery issue why not try to modify so it charger by a external wireless housing that you you could just fit from the outside of the frame while the bike is parked? I saw something similar with gps tracker
They make dropper posts that are actuated with a lever under the saddle. They’re usually cheap, and it could save you the trouble of mounting everything inside the seat tube.
wow this is very good, it opens a world of possibilities, such as the device being sold to adapt to any dropper, can you provide more information about the project please?
Have been considering something like this for a while now. Only issue is my 200mm dropper is already maxed out in my frame
You are the only one to do this. U should do a version 2!!!!
very cool! any tutorial how to do this? :) interested in converting my dropper to wireless. :)
Your should try to build wireless brakes for mountain bikes
I found your video looking for a product like this. I think it would be easy and cheap to add-on to. Existing dropper posts And you could sell quite a bit of them. I think I would start by finding the smallest possible actuator that can generate the Force needed by double so that it will last without wearing out. Seems like the actuator you have on. There is far stronger than it needs to be. And then you could patent the design......
This was inspiring
nice!
Awesome.
Hard to heard you through the "music", though.
Did you power the servo directly from the 5v pin on the XIAO or did you use a mosfet? Awesome video!
Directly
@@DAZprojectsthank you! Would you be able to share a rough wiring diagram? No worries if not! Thanks
Really interested in this - would you be able to drop some part number or links please?
I've got a 3D printer and nothing but time so keen to give this ago vs spending £700+ on Reverb.
I've found a couple of the items but can't seem to find the battery in that form factor.
Also Magura offer an Ant+ dropper remote you can buy completely separate for about £40 so wondering if that could be an option vs getting one made.
I don't suggest you build it because it doesn't really work, it needs to be refined and perfected
Probably external routed dropper post would be easier to deploy
could you show better the connection of the boards to the servo motor and the code written on the Arduino
How about a similar design but not using wireless, run a simple wire up to the bars for a press button to activate the servo. You could also include a couple of additional wires for the battery to add a charge port? I run my rear brake on the left side too so the wires could just be heatshrink onto the brake hose.
Then you can just use the standard dropper cable and heat shrink it to the brake hose
@@DAZprojects electronic would mean extremely light touch and invisible lever if I just used a small press button on the bars. I currently have an injured thumb that makes using a regular lever quite sore.
@@samnelson3958 that's totally true, I might consider that. I now have bought a dedicated dh bike to take to the bike park, so I don't need to have a detachable electric motor and I might consider to add a permanent one like the cyc or some other maybe diy system. If I do so, i could use the main battery to power everything so I don't have to worry much about optimising power consumption, we'll see
@@DAZprojects yes that was my thought also. Still need to consider the drawer of the servo motor at rest
Bro,what about a second version with n20 motor,worm gear and cable pulley inside the receiver? It might work more power effective than servo
I might try
@@DAZprojectshello , any news ?
Definitely don't stop refining this.. can integrate charge port were cable comes out seat tube. This would blow all other external wireless mechs away.
How much for one ?
Hi, Great project . Is it possible for you to upload the drawing and the arduino code for us to play with please?
I'll try to find them, thanks for the appreciation
Great job! I've also made a wireless dropper for a 27.2mm seatpost. The video is up on my channel along with a description of the components I used.
Nice work 👍🏻
@@DAZprojects Thanks, I just posted the final version, I think the project turned out quite well.
@@CorgonCorgon good job, maybe I'll revise this project in the future and make a product to sell, I'll see
@@DAZprojects That sounds good. I just made this as a private hobby project. I don't plan any further moves.
But if you're interested in the technical details, I'd be willing to share the info.
Can you please share the CAD drawing files and all the components you used to recreate it ??
So??
Why not add an external battery pack under the saddle?
There's no way of connecting it to the motor part down inside the tube
@@DAZprojects oh i see... Unless directly built in the post then. YS made one i think
can you send me the cad file of the controller !
Do you sell them?
unfortunately not
@@DAZprojectswhy not ?
Nice! finish it off better, make a port for charging and bring them to market. You'll get a work out going to the bank depositing all the money you'll make!
I buy it 300€ for a set left hand remote and motor.directly connected on 12 ebike battery
Make this a product, so anyone could upgrade to wireless droppers for cheaper.
Patent this and become insanely rich
Amazing work! @pinkbike get this guy's video featured!
I tried to send this project for one of their articles but they never replied
