MyDigitalSlot Left, Right and Double Lane-Changers, 3D printed DIY track parts for your 1/32 Digital Slot Car Racing Game

If you are finally into the "Digital" version of the hobby, then you will need these parts to create the Pit-lane, but also to increase/decrease the number of lanes or use double lane-changers.
If you want it all, the All Curves Pack and All Straights Pack is what you need. If you plan to buy these 3 publications, ask me for a discount and I will create it for you if you can't wait until I publish a "mega-combo pack" with these 3 publications.
You can use these parts in TWO DIFFERENT MODES:
Mechanic:
This is the easy one. You will only need a "Clipper Lighter Spring", four M3x8 Counter-Sunk screws and a few staples plus the copper tape and a few small cables to assemble it.
It should work with SCX WOS / ADVANCE and it works with the mechanical version of MyDigitalSlot Car Chassis

Electronic:
You can add this "electronic" feature to the lane-changers without disabling the mechanic system, so both modes can work same time.
To do it you will need to add an IR sensor with the right CLIP in the previous track part to the lane-changer, so the needle has enough time to move before the car reaches it. You will also need an arduino, a resistor and a servo to finally make it work "electronically". You can use the same arduino for various lane-changers.

This mode is specially interesting if you plan to use your old Scalextric Classic or similar track parts, as you can use simple standard car guides. The track parts come with the necessary holder for the servo and a "TPUtrigger" can be printed to move the needle with the servo.
These track parts can be compatible with other existing commercial track parts using the right adaptors.
To complete the connection system you will also need (INCLUDED IN OTHER MDS PRODUCTS):
- MDS_TRACK_CLIP_Standard (To connect track parts)
- MDS_TRACK_CLIP_Pianos (To interconnect pianos)
- MDS_TRACK_CLIP_Lanes (To fix straight lanes in parallel)
- MDS_TRACK_CLIP_IR-holder (To hold IR lights and sensors)
They are compatible with the next adaptors (NOT INCLUDED):
- MDS_TRACK_ADAP_SCA_CLASSIC_SL_STR45_FEMALE
- MDS_TRACK_ADAP_SCA_CLASSIC_SL_STR45_MALE
- MDS_TRACK_ADAP_SCA_CLASSIC_DL_STR45
- MDS_TRACK_ADAP_SCA_SPORT_SL_STR45_ROUND
- MDS_TRACK_ADAP_SCA_SPORT_SL_STR45_SQUARE
- MDS_TRACK_ADAP_SCA_SPORT_DL_STR45
- MDS_TRACK_ADAP_SCX_GREY_SL_STR45
- MDS_TRACK_ADAP_SCX_GREY_DL_STR45
You can find a list of the included parts at the end of the publication
MyDigitalSlot System, more than a track
This is part of a more complete work, a whole car racing Digital Slot System, including the track parts, controllers, car chassis, electronics and bodies. The same way various digital accessories like "Info Screens" with cars and race information, synchronised start lights system, RGB lighting, and probably an app and HDMI output will be available.
The main idea is to be able to print, build and use a full RC Car Slot Digital Racing System which is independent from market typical trades. Anyway you can use the different parts of the system in many ways.
The main features of MyDigitalSlot System are:
- Lap count
- Fuel and Health systems
- Racing system without base controller, just with cars and their controllers
- Race configuration and invitation system just with your controller!
- Stop and Go system for race starts and accidents
- Speed Cap system for low health or fuel
- Wireless and rechargeable controllers
- Enter / Exit Pit Lane detection, you need to stop there to restore full fuel / health levels
- Cars can run in both directions in the same lane
- Cars with full configurable lights, including dimming rear/brake lights, Left and Right Blinkers and Front Lights
- Cars can control various servos, a XYZ gyro, IR lights and sensors and the motor driver
More features are coming, but I will need a great bunch of feedback, I hope yours too, to take the whole system to a more professional, next level.
System Versatility
You can use the track parts to build and drive your analog or digital cars, you can mix the parts with older or newer Scalextric parts using transition/adaptor parts. You can also use the MyDigitalSlot cars and controllers in those commercial tracks, but the "digital" system accessories of those commercial tracks probably won't work.
The electronics involved in the controllers, cars and digital track parts are quite simple and easy to source, like cheap arduinos, resistors, diodes, leds, RGB digital leds, pots and a few more things.
I have made the car and "lane-changers" work in two different modes, one would be compatible with "mechanical" lane-changers like in Scalextric Digital System, WOS or Advance.
The other mode would be the "InfraRed" mode, in which the "lane-changers" will move when they receive IR light from a car. In this case, you won't need the "line-changer actuator" in the car but you will need electronics under each lane-changer track part, specially the "sensors" and the "actuator".

There is a very good thing about the InfraRed lane-changers... You can use both mechanical and IR systems simultaneously, I mean, one car can change lane mechanically and the next one could use the IR led to change lane.
You CAN'T use "mechanical lane-changer cars" with old Scalextric track parts (black) but you can use "IR lane-changer cars" and complete your track with all those old track parts you had around there from many years ago.
Printing a big track could take many many plastic (various KG) and hundreds of hours of 3D printing, so this InfraRed lane-changer system in combination with your old black track parts could be the most economically interesting solution from my point of view.
If you give it a try to MyDigitalSlot you will be welcomed to my Discord Server to ask, show or suggest any change to this DIY 3D Printable Digital Slot System, but you can also use the comments of this publication if it makes sense.
