DIY sequential gear shifter for sim racing
September twenty sixth, 2023
—A sequential transmission is one which solely lets you transfer up or down by a single gear at a time. They’ve at all times been the norm for bikes, as a result of they’re light-weight and compact. And System One automobiles have sequential transmissions for a similar causes. However not like bikes, which require handbook shifting, System One automobiles have lightning-fast digital methods. To recreate that for racing sims, Carlos Almeida designed this sequential gear shift controller.
Actual System One automobiles have paddle shifters, in order that drivers can shift whereas holding their palms on their steering wheels. This can be a little bit completely different and appears extra like a traditional shifter at first look. It’s a giant lever that the person can push ahead to maneuver up a gear, or pull again to maneuver down a gear. A seven-segment show exhibits the present gear quantity.
Many of the mechanical parts are 3D-printable and an Arduino MKR1000 WiFi board is the first part. Transferring the shift lever pushes a swap, which the Arduino registers. Almeida developed the sketch utilizing PlatformIO. It units the Arduino up as a normal USB HID that can work with any racing sim or recreation, as a result of it sends key presses like all keyboard or gamepad. It doesn’t obtain suggestions from the PC, so it has to maintain observe of the present gear and let the person set the variety of gears obtainable utilizing small buttons under the readout show.
If you would like a bodily sequential shifter for racing sims, this can make an important weekend mission.
