  • steveo9007: Cheers Atom was just a thought for now as I plan on keeping it well in range until I get comfortable with controls and flying

  • atomiclama: steveo You can just plug a GPS puck into the FC and get the OSB to display the coords, record the VTX and when things go tits up you have the last known posistion. Whislt not accurate it is a good starting point. Or get the coords sent back by telemetry to you TX which will be more accurate as long as power is maintained to the quad and it is range with the TX. Just some thoughts.

  • steveo9007: Is there a post on here about the 433mhz telem tx ??

  • steveo9007: ok thanks shaw
    December 03, 2018, 20:31:44
  • shawdreamer: meanwhile the 433mhz telem option I mentioned gives you live fixes in realtime and not "delayed texts"..... plus it doesnt cost you credit everytime you request a gps fix (btw the tags sim card also needs to have credit on it :laugh:)

  • shawdreamer: and yes that does actually work..... I tried it for a laugh a couple of years ago ::)

  • shawdreamer: the tags do as you say use satellites to get positional fixes but they dont immediately report those fixes to an App, each tag requires a Sim card (same as your phone) which is used to "text" you the tags position..... in other words you could get the exact same effect by strapping a old smartphone to your frame with the google "where is my device" app installed
    December 02, 2018, 20:44:13
  • steveo9007: doesnt the tag communicate with the satellites and not via a data system, isn't it the user who owns the tag go via data to the app that can locate the tag ???

  • shawdreamer: plus, alot of the lower end trackers struggle with GPRS and often rely heavily on GSM data instead which is just not worth a sh1te when it comes to pinpointing a downed frame
    December 02, 2018, 16:23:30
  • shawdreamer: most readily available gps trackers are not really suitable for anything smaller than a 400 sized frame as the units themselves are often too bulky for anything smaller and larger frames often already have their own gps setups that can simply be outfitted with a 433mhz telem tx that would report live and accurate info direct to a ground station so there'd be no point in a sms type tracker

  • steveo9007: anybody fitted a GPS tracker tag to their drones if it gets lost and is need to find it

Automated Race Control and Timing
« on: October 02, 2018, 19:39:40 »
Many will know I run an after school RC Club. This year we are concentrating on Whoovers (Tiny Whoov in the USA).

I tried Tiny Whoops last year but it was beyond the bulk of the 11-13 year olds.

When we were doing indoor RC Cars I gained a full race control system called iRace from a UK source. Used it for three years. Its possible to do during practise auto registration, auto allocation on times to heats (and finals), full audible output, auto speech announcer, bleep countdown start, etc.

This only needs a low power (time served!) PC laptop and IR senders/receivers. A system is approx £300 and extra transponders are £12 each.

I have just minimally modified a number of the Transponders and proved the system will work on 1S supply down to quad LVC.

I have also done a more stringent mod to one to reduce its weight from 3.4g to little over 1g. We have held one full race meeting for Whoovers on this system with no errors.

I know some more expensive quad FC's are being fitted with transponders but we are using the Eachine E010/JJRC H36 quad as a base for a one design class as this is available for sometimes under £10 with transmitter.

I also know there is also work taking place on lap counting by proximity sensing on the video frequency but as I understand it this is for ranged outdoor use, not tight indoor.

The purpose of this post is:-

1. To make people aware of the potential for using an iRace system for Indoor Quad/Hovercraft Racing.
2. To ask people wanting to arrange racing to express an interest in adopting this system

The UK maker and UK retailer are willing to consider tuning the system even more specifically but need an idea of take up for their efforts. I stress that at this stage the system would be for INDOOR use from a mains supply. They have had enquiry from elsewhere but no serious interest, and so I'm offering co-ordination.

I'm only a happy user with nothing to gain other than possibly an even better product!

Over to you...............................

47 views, no comments!  :shrug:  ;D

I have now worked with the UK designer of the RC car transponders and we now have a micro 10x10x4mm unit weighing under 0.4g working well on test. This can be fitted INSIDE a standard E010/JJRC H36 65mm quad canopy looking out through a less than 4mm hole and using the std quad electronics.  Cost to be confirmed but likely under £12 per transponder.

This means there is the ability to automatically control and time races for Indoor close proximity LOS and FPV Quad and Whoover racing. I have yet to test outdoor operation, mainly as the (obsolete) laptop I use has a duff battery!

My system controls practise, allocation on time into heats, finals, audible announcements, best/average lap timing, etc
