Iain's 20XE Trackday Nova

Good tip, I'll remember this for mine........oh never mind!!

Buying a sequential was plan B, thankfully I managed to fix the gear linkage slop.

I had problem with the cable turret, there is the breather about 50mm deeper, so need a longer hose to avoid.

Smart fix :thumb:

Anyone in this little trackday-related project I've been working on?

Borrowing Houses Vbox was great and I was loving the video overlay with speed, GPS track location. But I couldn't justify £310 for a proper vbox, despite them being a great piece of kit.

Here's my solution, Raspberry Pi Zero, 10z GPS hat (with accelerometer, gyposcope etc, but not using that atm), running some custom code I've written. It essentially dumps GPS location data every 0.1 seconds to an SD card file which I can use in Race Render to overlay speed, track location and G-force (calculated from GPS data).

Pi + GPS hat:

Broke out the breadboard to mock up the wiring; LEDs and operational buttons.

Once that was working it was all soldered to fit in the small case:

Finished product including external antenna (antenna plug on rear of device) and external power bank.

In short; You power it off the powerbank, press a button on the side to start/stop recording and various LEDs show power, GPS fix and recording status. It dumps raw NMEA GPS data to the SD card which Race Render supports for video overlaying.

Pure wizardry!

You're a wizard Harry

Turns out by simply pressing the GPS start button and GoPro record button at the same time, the data and video sync up perfectly. Lovely job.

Took it to Blyton Park 30/08/2020, great day, lots of fun. Had a few issues including a coilover platform winding itself down but all easily resolved.

Brakes weren't very strong, so put some new F4R pads in on the day. During bedding them in I got a bit excited:

Resulting in me smacking a cone, cracking my new front bumper and ripping a side skirt off going sideways over the gravel:

The marshall kindly delivered me my skirt back at lunch and refitted, nobody will ever know:

Here's the last session of the day, with new GPS data overlay:
