#SIM RACING HANDBRAKE XBOX DRIVERS#

In both real life racing and sim racing, there are 2 types of handbrakes that drivers can choose from, the regular cable handbrake and the hydraulic handbrake. When used properly, handbrakes can help you increase your overall performance and achieve a new lap time record.

#SIM RACING HANDBRAKE XBOX DRIVER#

In real life racing, handbrakes are crucial in giving the driver extra control when it comes down to rallying and drifting.įor the same reason, using handbrakes for a sim racing will provide you a much more immersive experience than not using one. Unlike those components, a handbrake is something that you can race without when it comes to simulation racing.ĭespite not being a necessity, handbrakes can drastically improve your sim racing experience. The software, followed by some of the most crucial hardware such as the driving wheel and pedals are amongst the most important factors when setting up afully fledged sim racing cockpit. Often regarded as one of the most complex esport, many sim racers like to get very detailed when it comes to setting up a sim racing rig. The world of sim racing is getting more advanced and detail oriented. The hardware and firmware can be found on my GitHub repository at.

#SIM RACING HANDBRAKE XBOX SOFTWARE#

For these games I adapted a small software tool based on VJoy, which merges multiple controller inputs into one virtual controller. However, some games do not support multiple controllers at the same time. The firmware presents itself as a HID-compliant game controller to any OS supporting the HID protocol (in my case Windows), such that no device driver is needed.

#SIM RACING HANDBRAKE XBOX CODE#

This library implements USB V1 completely in software, as this microcontroller has no native USB interface.Īpart from handling the USB stuff, the code is pretty simple: Initialize the ADC, blink the LED, and then in a loop query the ADC, pack the value into a USB packet and send it off.Ī small but really interesting hack is provided by the library: Because the internal oscillator of the Attiny is not precise enough for USB timing, the code measures the signal times of the USB packets received from the computer, and detunes the internal oscillator accordingly using the OSCCAL register. The firmware code relies heavily on the excellent V-USB library by Objective Development. Programming the ATtiny is pretty easy, I use the avrdude software and an USBasp ISP adapter. After debugging a few problems related to my own stupidity, the PCB was ready to be programmed. Next, I printed, etched and assembled the circuit. Two capacitors are used to smooth out the power supply, but I think they are not strictly necessary. Schematic of the control circuit.Ī red LED is used to signal the operation status, and two Zener diodes are used to drop the 5V supply voltage down to 3.6 volts for the USB signal lines. The circuit is fairly simple, all the logic is handled by an ATtiny85 microcontroller. For this, I designed and built a small PCB which presents the potentiometer data via USB to the computer. So, the next problem was somehow getting the movement data into the computer. Some small adjustments had to be made, but in the end it worked out fine. A spring (silver) provides the “mechanical feedback” to the user and also limits the amount of travel so the potentiometer does not break.Īll in all, the build went about 95% to plan. The lever then actuates a linear potentiometer (yellow), which is mounted on top of the clamp. The rail is then screwed to two L-shaped pieces of aluminum (red), which in turn are screwed to a desk clamp (green). I used a spare Actobotics rail (blue) from a previous project to mount a bearing for the lever (violet).

The mechanical buildĪfter an inventory check of what parts I had lying around, I drew a quick and dirty CAD model: Handbrake CAD mockup. So instead I opted to a vertical design, which is often found in racing / drift cars hydraulic systems: E-Brake installed by Josh Buittner – Langhorne, Pennsylvania USA. Originally, I wanted to build a system similar to a classic handbrake in a commercial car: A standard handbrake lever.īut this quickly proved to be a challenging build, because I wanted to clamp the thing to my table. Surely I could build something equivalent similar out of parts lying around? Inspiration So, I set out to acquire a handbrake controller, but quickly decided to build my own after seeing the retail prices often above 80€. And pressing a button on my steering wheel controller just doesn’t cut it in terms of control and realism. But sometimes, there is also the Need for Smooth Drifting Around Tight Corners. Of course, there is always a Need for Speed in racing simulations.
