PWM controlled Brake light controller [Open Source]

Aren’t flashing lights supposed to be way more noticeable than solids? I mean emergency services use flashers…

i literally ran into somebody i couldn’t see because one dude had a flashing light and the other one had no lights. Tried to go around and basically slo-mo bumped into another person. I skate by moonlight all the time, zero issues… until lights…

So then clearly the brakelight should be solid and unflashing :slight_smile:

They are. So much so in fact that it’s ALL you notice. For several minutes. Even when no longer looking at them…

emergency vehicles also use horns and sirens well into the permenant hearing loss zone. Not interested in that either.

I’ve got some 42V Toyota forklift horns all ready to go

Sucks if you’re on 12S… :smirk: you’ll need a converter most likely

Jake was legit looking for train horns for his board. I can’t even imagine the nightmare that would ensure for cyclists… hahahahhaa

I’ve checked into those before as well. The air compressor setup is not kind to the space available on a longboard, and definitely not a shortboard.

Strobes are more noticeable but because our brain is programmed to make us look at it, this can be dangerous. At night, once your eyes have become accustomed to the darkness, your retinas enter a state of photophobia where any bright light can disrupt your process of thought and movement. And since we perceive flashing lights as being brighter and more noticeable…crash and burn

I want this! Good pwm lights are a gap that needs filling. Plus It’s the upgrade I might be able to afford.

@Mich21050 What’s the max watts it can deliver on the front side? My headlight is pretty demanding

Ah ok maybe a slower pulse/breathing style flash would be better?

@Mich21050 Quick question: How do you switch it on/off? Does it have its own switch? If I use Unity with its built-in e-switch, is there a way for me to use the light controller without adding another switch? Such as use the 5V from the Unity as enable signal?

Actually that would be a really clever idea I never thought of… until now I always used the 3rd channel to switch it on/off. I will definitely look into that.

What interface would you guys prefer?
The standard uart or PWM interface… also after talking with a friend of mine we came up with the idea of a complete standalone unit using a gyroscope/accelerometer setup… any comments/ideas would be appreciated… :slightly_smiling_face:

I’d prefer PWM

Maybe best to allow both? You could have PWM firmware and UART firmware. The user then flashes the one they want.

You could expose the RX and TX pins. Then if the user wants PWM, I believe it can be done over one of the pins.

Ah, you switch it on/off in software. OK. How does the MCU power on/off?

A braking light using a gyroscope already exists. But if you could have a cool design of one why not!
