Putnam Video w/Telemetry

[Dunc]

Thought I would share some screenshots and video. Went to Putnam again back on 07/25/10 for another round of riding in the intermediate group. I managed to pull off a 1.25.xx lap but most were betwen 1.26-1.29 with the majority within 8 tenths of each other in the 1.29 range. I was sort of disappointed in my lap times, but I'm not worried about that because I know where to go faster now thanks to the telemetry. I think I need to carry about 30mph more through turn 1 and also the carry more through the bus stop at turn 7. Typically I make up ground by carrying more speed than others through turn 4-6 and 10.

Anyways here is my lap timer setup. It logs the following every 0.2 seconds via a 5hz bluetooth receiver straight to my phone. Total cost excluding the phone was $55.98. You can log everything just using the phone which would make the cost $6.99 instead. However the phone can only log once per second (1hz) and that's just unacceptable so 5hz+ is pretty much mandatory.
- Split marker number
- Lap number
- Lap time
- Split time
- Latitude
- Longitude
- Altitude
- Bearing
- G-forces
- Speed

Optional data logging:
- Throttle position
- RPM
- Temperatures (i.e. coolant, etc)
- Pressures (i.e. oil, etc)

For the optional data logging you can get this wireless as well. However you need to have an ODBII port. Since my bike doesn't have that I can do it *tear*. Oh well though, this is good enough since I don't feel like paying $600+ for a premade GPS system.

From here I've put together an Excel spreadsheet that takes all the data by lap and calculates distance traveled between the lat & long coordinates and other various items. This also allows me to create and X/Y graph which is used to draw the track layout. Then I use a program that animates the Excel data and saves it as a video file. Finally I use a video editor and overlay the telemetry to my videos. The program I'm using can overlay up to 7 video feeds so at my next trackday I'm going to have about 5 cameras total on the bike to get a few angles at once. On to the pics and video....

This is the main screen when review the session while on the phone. Those clock-like looking things at the turns are the locations of the split markers. To place them you just zoom in really far in the satellite view and place a small "x" on the track. I haven't tested it though, but I think there is a small radius around that point so it'll still pick you up even if you aren't on the racing line. I need to tested that out though.


This shows the available export formats for the data.


This is a screen shot of my computer after export the data to Google Earth. I took out the data points because in a 1.30 lap there are about 470 points. This was clutter for this picture. The white line is my drive line and where there is a break in the green/red shading indicates where I was holding the speed/accel constant. There was a hiccup in the GPS data at turn 5 on this lap. As seen it looks like I went off-roading lol.


This screen shows the available track layouts. You place your split markers around the track via satellite images through Google Maps. When saved you can switch between the tracks so when you get there all your split markers are in the same spot as last time. These are shareable files so you can use other peoples track layouts they create.


Here you can instantly review your split markers while at the track.


The phone logs each session separately. This is just a graph for one individual session.


Here is the video (be sure to select 720p if it doesn't do it automatically):

I love trackmasters! Great app!

I was wondering if you can help me have the overlay that you have with your video! I was just thinking how do i this.

Thx!

Definitely. Are you familiar with racechrono2avi? if you send me your logged files I can put it in the excel file and send it back to you.

Never heard of it before in my life! Let me see if i can figure this out first! Looks pretty neat!

Mods include:
- -1/+2 Drive sprockets w/520 chain
- Jardine GP1 slipon exhaust
- ASV levers
- FrenTubo Carbon brake lines
- Ferrodo pads
- SuperBlue DOT 4 brake fluid
- K&N "street" filter
- Set up for GP shifting
- HID Retrofit (by me) and customled tail light
- Servo motor eliminated

That's about it. It's pretty stock. No exhaust or power commander or motor work. I'm currently throwing around the idea of getting some BST carbon fiber rims though.
