Albert from Vancouver lent us their lap timing system a few weeks ago, which led to us having the most lit intro ever. Live time callouts had us pushing us to the limit, to get faster every lap.
(I know this is EUCs, but it’s the video I’ve got! Same thing but with boards too. I know it made me several seconds faster that day)
We all wanted more of it, so Estelita got in contact with Lap monitor and we did a big group buy of 30 transponders and two base stations.
A big reason we’re doing this is so everyone can have a transponder permanently assigned to them, so their name can be permanently in the lap timing system (which makes track day admin work significantly easier).
I was tasked with building standalone enclosures for everyone and soldering together a battery, BMS, and a switch. After much iteration, this is what I came up with;
One piece print with just enough space for the transponder, BMS, switch, and an 18650 to hold everything in place. I initially made a single unit to test and make sure the design would work.
Because I couldn’t leave well enough alone, I disliked how the base station didn’t have a power switch and was powered off AAA batteries. So I designed a new backshell to replace that with the same BMS, switch, and 18650 as the transponder case
Print quality isn’t great, but that’s fine. Doesn’t need to be that durable.
(Charge port is under the grey rubber case)
After a track night with no failures, I deemed it good enough to go into mass production on the transponders!
We went with a nice bright orange so they’ll be easily visible. Think it’ll give a nice feeling of community seeing everyone having a transponder on their PEV.
And that’s where the project stands now. The plan is to assemble the rest of them this weekend and start giving em out to people next week. Psyched for the upcoming intro’s with these!
My secret to success is Huey, resident 3D print supervisor.
