That's looking more promising, It's successfully compiling, but when it tries to upload it's not finding the board. Generally this happens if the wrong port is selected. If you unplug the arduino, then in the Arduino IDE go to Tools>Port and note what ports are available, then plug the arduino back in and repeat, a new port should have appeared. Select that one and try uploading again?
I'll message you my number now - give me a call if that doesn't work.
Hi there.. I'm John and, as one of the Grandparents, I help to support 'The Pod Movement' team from Chipping Sodbury School.. I find myself on racedays, glued to our telemetry giving a minute by minute 'commentary' on how I think the car is performing. Our telemetry is a very basic direct radio link with the car, into a laptop..but it works! I'm new to this forum, and to the telemetry system you have described at length on the net.. Having only seen the article for the first time today, I have yet to really get involved, but I would like to take this opportunity to thank and congratulate all involved in the production and presentation of the practical information you have made available to the rest of us. It is truly an excellent piece of work. The system you describe looks to be ideal for the kids to learn from and employ. I'm sure, in time, you will get questions trom me, but for now, many thanks. Regards John Rees, Chipping Sodbury, near Bristol.
Telemetry makes the race so much more interesting for those in the pits - I think it increases stress levels as well though...
We used to use a radio link from the car but always struggled with range. The phone is far more reliable on tracks that have signal, but there is still the odd track with none.
If you already have a system that sends data out through serial (ZigBee or similar?) It's probably not too much work to swap that for a Bluetooth module and connect it to a phone with our app. You might well be able to do both if you have a spare serial on the microcontroller. Happy to help if you want any assistance with it
Hello. I have planning for some time to join the forum and write a post thanking you for the great job you have done with the eChook! I'm one of the mentors working with the Banchory Academy team who have built and run the "50 Shades of Green" car. In the 2018 season the car placed last and second last in our local Grampian Transport Museum heat :-(. Back in those BT (before telemetry) days the testing approach was basically make changes to the car and see how long it would run with a fresh set of batteries! This year, with the benefit of the eChook, we can now see in detail how the car is performing and it has allowed us to make and evaluate changes much more quickly. Results - we won both races at the 2019 Grampian Transport Museum Heat, and had a 1st and 2nd at the recent East Fortune heat. We also received the Siemens Digital Award for our telemetry which we had showing on a big screen in the back of our van in the pits (drew quite a bit of attention). The pupils involved (and the mentors) are very excited at having qualified for Silverstone, and we are now tweaking the car further and planning our trip down south next month!
Our use of the data provided by the eChook has matured from fighting with Excel to process and chart thousands of rows of data, to uploading the data to a database to allow post event analysis, to now capturing the live dweets from the car into a database from which we can provide a real time dashboard showing how the car is performing, charting trends in the data, and predicting how long the batteries will last and race distance. I have attached a few screenshots of our screens (synthetic data). Confession - although I have been watching the eChook site and forum for some time I only recently discovered your Live Data demo pages (I had assumed that the Live Data on the web page menu bar would take me to the same place as the "View Live Data" link on the home page). There are quite a few similarities between your Live Data and our screens :-).
Starting after Silverstone the team are going to embark on building a new car. Telemetry will be built in from day 1.
If you are going to be at Silverstone it would be great to meet up and exchange a few ideas! I'm also going to go post a reply on the Arduino Code thread on the forum - I have a couple of corrections / suggestions for changes to the Arduino code.
Once again, many thanks for making the eChook available. It provides a huge leg up in understanding how a car is performing.
Hi Keith, that is wonderful to hear, and congratulations on the race results!
I love what you've done with the telemetry too, both that you've set up a site and database for it and that you're showing the data publicly. One of the features I'd really like to get working is a spectator page that just shows all the eChook cars location on a map of the track that everyone can access and watch. How have you implemented your interface and database?
The beta live data site has stalled a little - we were finding a fair few bugs and as we're not actually racing a car any more testing is difficult - I've spent a lot of time walking around a park trying to emulate laps and reproduce errors! The result is I'm having a rethink about how it should work and possibly simplifying it a bit. However PM me if you want an invite to the beta app, the live data site works unless you're using the lap counting feature and you can still use dweet at the same time.
I should be at Silverstone and an always up for a chat. Need to check how many days of holiday I have left...
Thanks for sharing, and I'll take a look at the Arduino suggestions
