Lap Timing Decoder
#436
I only have access to MyLaps and AMB decoders about once weekly, and then all of my time is spent racing (usually four or more classes!).

Hi,
if anybody is interested in this project, I have a few PCB's here.
When I ordered them I got a few more delivered.
It's Cano's Layout as you can see in the pictures.
Just PM me and we talk about the price and shipment (I live in Germany).

Ok. I don't know enough about it. I was thinking of it more as shielding the concrete than the loop. Stacked as concrete, shield, loop, and carpet.
(Edit: Or if using a bridge; concrete, shield, carpet, transponder, loop.
Can shielding material be bought in sheets? Surely guys who do car stereo installations use something like that.)
I haven't chimed in, but I have been lurking. I have an RC4, but it was very hard to come by. I think the club for who can be a race director is too exclusive, too expensive, and just too difficult to get into. You and this thread. You have kicked a door open, for those who may not be loaded, but are determined or otherwise able to do it. You have made a way.
Decoders should be five or six hundred bucks. Transponders less than forty, but that is just my daydream. You are doing a good thing here. I wish I had more to contribute than my encouragement.

Hi Snoopy,
i had the same thought as you to shield the concrete, i am in the process of building my decoder now since i did not get aoround to it all summer. So once its built i will test on a concrete floor.
As for this equipment being too expensive your absolutly correct considering how cheap components are! There should be a low cost alternative and this one is the way especially considering that Howard has designed an inexpensive transponder, we can just build our own systems and transponders.

I also have extra decoder boards, but no transponder boards. I would be interested in buying some of your trasnponder boards! PM me.
thanks

Hello Howard,
I am in the process of building my board finally!
A question for you, concerning the Crystal that goes in XTL61, there are 3 holes. Which holes do we use?
thanks

Hello Howard,
For the serial connector, im looking at schematic and I dont see any information about it.
At jumper J65 (square) I assume is data?, what pin does it goto on the serial db9? (TXD 3) ?
and round to what pin on db9?

Yes, the quantity for 22pF is incorrect.
J65: square pad is data out, round is ground. The wiring for the DE9 will depend on what you are connecting to, but here are some typical connections:

So it would be pin 3 & 5 on serial connector? (TXD & GND)

If you are using FlipSide scoring software, you will also want to connect pin 1 (square pad) of J66 to the incoming RS232 data (pin 3 on the DE9, in my case). This was a last-minute change requested by FlipSide; any character received by the decoder will reset the internal timebase counter.

I'm using pins 2 and 5 to connect to the Sabrent SBT-USC6M USB to Serial Adapter Cable.

Thanks for the clarification on Flipside! I dont think im going to use it so far looks like i will go with Zround timing.

The labeling is for the connector on the PC. The PC receives data on pin 2, so that's where the decoder needs to send it.
