What did you do to your TRX-4 today?

50663321096_8b17c9b380_z.jpg

Lights finally came in off back order.
 
Today, I decided I should put lights on my TRX-4 Sport Kit. I had looked at the Traxxas light kit but was horrified at the price, especially as the Sport Kit comes with all the light buckets. However, I wanted working brake light and the ability to turn off the headlights. So I had a dig about in my Arduino bits box and pulled out an Arduino Pro Mini, some LEDs and some wire. The result is working headlights and side lights, rear lights and brake lights.

Basicly, I have hooked channel 3 (direct) and channel 2 (with a Y cable) on my FS-GT3C up to the Arduino. The Arduino reads the pulse width on the channels and the code turns on the lights when Channel 3 is activated. It also monitors the Channel 2 and puts on the brake lights (increases the intensity of the LEDs used for the rear lights) when the pulse width is between 1450us and 1550us.

All in all I am pretty happy.

Man! That's awesome! I'd love to see a tutorial on this and the code :ror:
 
Got brushless installed and tuned through the castle link best as possible within the confines of the house. Saturday if all goes well a test run outside in the melting slushy snow mild Canadian winter we have been getting. 1/10 MX ESC and HH 3800KV TMPBL motor geared at 45/10 on 3s and single speed conversion done along time ago.

Use "CTRL + Print Screen" to take a screen shot of your program. Then use "CTRL + V" to paste it into a graphics program and you can crop down to what you want to show us. Then save to your hard drive.

Taking pics of the screen like you did, makes it hard to read. But thanks for sharing tho :)

You can get a great image editor called GIMP. It's free and you can do almost anything you can do in Photoshop.

ended up putting cherokee body on, changed the bumper and added a winch and new rear bumper with spare, hyrax tires, 6 channel reciever, now i'd like to do something about inner fenders to hide that open look, then interior later on.

Well, I lied about the Light bar. I was suppose to get it on Friday and my store didn't get one in. I'm leaving it on the list cause I am ordering one this week.

Here's some pics from this weekend's competition.

Hi! Yeah, the comp was a blast. On the 1st course I ended up with 22 points :(
Second course I got a DNF cause I ran out of time. Winch hook broke and that set me back.

A buddy was able to tune my ESC before the comp started.
I still haven't got my connector from Castle.
