Disclaimer: it’s not about tuning or manipulating the speed!My used scooter has a very imprecise speedometer, a tank indicator and a few more lamps. As a hobbyist, I therefore came up with the idea of whether a digital display for various information could be retrofitted.Here are the features: + no structural intervention + access via Android & iOS + tachometer with Vmax/Vavg + tank/drive book + total/day kilometer + compass/GPS position + tachometer + engine/outside temperature + Battery charge + petrol/oil tank level + date/time + location/theft tracking + push notification + …What else do you want?The entire display will be completely open source, i.e. the electronics, hardware, firmware and 3D housing can be retrofitted, improved and even commercialized.The material costs would be almost 15 euros.Technical implementation: * OLED (display) * ESP32 (wifi/bluetooth) * GSM module (Internet) * GSP sensor (tacho) * HALL sensor (turnaround) * NTC sensors (tem) peratur) * RTC module (clock) * LDR sensor (dimmer) * … No cables can be tapped for implementation, via which an electronic throttling could be realized or which mean a structural change in the sense of the penalty regulation. During the ride nothing can be adjusted at the settings for security reasons. The scooter must stand to adjust the mini-board computer via smartphone. If such a digital display would be interesting or there is this with the above mentioned function Is that what you’re talking about?
