DIY Active Pedals project for sale!

Description

DIY Active Pedals kit parts for sale!

I am hereby listing for sale the parts I bought for my active pedals project as well as the 3D models I designed for the structural components. Please read carefully.



-The idea: 2 pedals with motors with high torque that not only shake your foot but can move it in a raw and unfiltered way if desired. Why? Firstly, you can adjust this strength so more power is better. And secondly, it can simulate more effects simultaneously without numbing any of them, imagine it like a high torque wheelbase.



What the listing includes:



-2x 57HS112 motors (stepper motors, 4Nm of torque each)



-2x 100KG S-Type load cell sensors



- 5x HX711 load-cell controllers (1 needed for each pedal but I bought more just to have)



-2x DM556 motor drivers (more than powerful enough, they offer microstepping of the motors)



-Arduino Mega 2560 Pro (more than enough computing power, easy for coding, popular and reliable choice)



-36V 13A PSU (CCC, FCC, CE safety compliant, has shortage, overvoltage and overload protection but it’s calculated to be more than potent enough)



-2x 150mm-long 8mm lead screw mechanisms with 2 brass nuts for each one. The idea- bigger contact zone for better force handling and transmission.



-2x 150mm MGN12H linear rails with the blocks. The idea: to mount on top of the block a part that combines the brass nuts of the lead screws and the SK12 units which connect to the lower part of the load cell sensor arm.



-4x SK12 mountings - for mounting the load cell sensor onto the lead screw mechanism coupling, 2 for each pedal



-2x 8-8mm universal joints for motor - lead screw mechanism coupling.



-8x16x5mm bearings - 50pcs. 2 per pedal leg (4 for one pedal legs set), also have to add on the upper LC arm mounting on the pedal arm. More than enough ones quantity-wise



-8x12x3.5mm bearings - 2 per SK12.



-metal flanged sleeves for each hole for structural rigidity - again, more than enough quantity-wise



-I have also created every single 3D model needed either for 3D printing or CNC-machining the structural components which include:



1.) mounting platform for the motor, lead screw mechanism, linear rails and the pedal arm



2.) the pedal arm



3.) the components that connect to the load cell sensors, the upper one connects to the pedal arm and the lower one to the SK12 units.



4.) the part that mounts on top of the linear rails’ blocks, houses the brass nuts of the lead screw mechanism and mounts to the SK12 units which sit on its top



5.) the pedal face with tapered holes so that it can be adjusted.



-Every single part of these has FEA (finite element analysis) data and has been optimised multiple times to handle and transmit the forces better. More than 40 iterations and approximately 100 hours of optimisation and changes to optimise the kinematics as this is one of the most important things in the whole project.



-The current stage of development: the only things that remain are bolts (M8 bolts everywhere except the SK12 mountings which are M5), nuts to tighten them, miscellaneous things (resistors, additional fuses if needed, etc.), a power supply cable and the coding. The coding is simple and my plan was to combine available repositories of the load cell sensors coding and the motors codes and just get it to work with SimHub plugin but you can code a program yourself of course. Also remains to configure the wiring but the the scheme is supposed to be simple as this was a target of mine when developing the pedals.



-if desired, I can send more pictures of the components, the FEA results, previous iterations, parts’ serial numbers and others if needed. I even have 3D printed mockup models of the printable that I can send pictures of.



-the reasons I am selling the parts and models of this project are numerous. Firstly, I decided to prioritise another similar project I am currently working on and I need the money and free time to build it. Secondly, the need for active pedals disappeared after getting high quality pedals with haptic feedback.



Thirdly, I enjoy working on my projects more than utilising them.



Attaching photos of some of the fore mentioned things the advertisement is about as well as the rendering of how one pedal is supposed to look. The parts and the whole project is for two active pedals. Can send more photos, receipts or whatever else you need. Please also note that this is the current stage of the project of mine - additional 3D modelling might be necessary, might need other types of parts that aren’t part of my current design, might need kinematics optimisation (very good as of now but still). I am in no way selling a product or a finished project. What remains in order to have 2 working active pedals compatible with SimHub is another 30€ on the parts mentioned in the post, coding which is also mentioned in the ad (as well as how I planned to do it) and to 3d print / CNC machine the already provided files of the components. 3d printing the parts for the two pedals is estimated to be around 3kg of filament in my case but it depends on the chosen slicer settings and materials used.


Asking price: 800€ - including every single of the mentioned available parts as well as the .STL, .3MF, .STP, .STEP or any other format of every single of the mentioned printables (that can be also CNC-machined). Would be better to be located in Europe so that the shipping is faster, easier and cheaper and with this being said, the shipping is on the buyer.
