RC Car Active Power Distribution
I am also planning to bring this monster back to life -
|16 Bit Integer|
|Fixed Point 10.6 using 16 Bit Integer|
|Howie314 - Using an LCD Shield for a fast build|
|This build by Arduino Forum User Howie314 uses a LCD Keypad Shield, it keeps the size down and means there is very little soldering required to build the project. Many LCD Shields are available and all work in a similar manner meaning that you can get a lap timer up and running quickly with almost no soldering required.
If someone would design an LCD Shield with a rotary encoder as well as buttons we could have the perfect lap timer interface.
Howie314 is one of the first using the most recent version of the code with the new options of external audio and countdown. Additional options that I am considering in the near future are 1) Window magnet transponders and 2) AIM Transponders. See the end of post for more details.
|Howie also did some work on the user interface as the LCD Shield uses a single analog pin to read multiple buttons. It makes sense to offer a version of the build along based on these readily available shields so I will be taking a look at Howies modifications with a plan to offer a single version of the project which can be run on standalone builds or LCD Shields - props to Howie.|
|ALLY's Build and Enclosure
||Arduino forum user ALLY has used a standalone LCD and soldered his own buttons. This gives a bit more flexibility in the type of display and enclosures you can use, but also requires more work to build.|
|ALLY Transponder Mount
||Here is a shot of ALLY's transponder mounted in his RC Touring car. Notice that the IR Emitter is mounted on a small post, this is a nice solution as the LED is well away from any areas that would impact in a crash.
If you want to try something similar make sure to keep the wires to the LED short. I tried wires of about 15 cm which unfortunately acted as an antenna causing radio interference.
||ALLY has used a large carbon fibre effect enclosure, there is lots of room to add indicator LEDs, or one of my favorite features - a small amplifier for optional external speakers.|
