Pleas guys, learn from the Brigate Rosse. Put him in a f*cking trunk (use a chrysler pt cruiser for the occasion please) and goodnight.

I don’t think the main target is civilians, I think they have better targets (strategically speaking), you are right in this

A friend brought esper affinity with Glint Hawk for a “weird pauper decks” event! Lens flare also for the flavour. It did surprisingly well.

It might happen if the force applied to break is too high, right? So is it possible that I tensioned the cable too much when setting the breaks?

hi, thanks for the early reply.

the relevant output is j6 which is connectect to six red lasers with separate positive terminals and a common ground to power them independently using the pwm function of arduino. They should be a mostly resistive load but they have quite high parassitic capacitance. We can't have separate grounds and switch low side since the external casing of the lasers is connected to the negative terminal of the laser diode and it is bolted to the same aluminum frame. The lm317 is working as a constant current driver and we found online that it's best to switch Vi instead of ADJ in this case link. Is it possible to use the circuit in the first schematic of the link to solve this? We are currently dropping .7V between base and emitter of the transistors.

Could otherwise placing the switching transistor after the cc driver be a solution?

The circuit seems to work perfectly with a lower voltage laser diode and doesn't seem to have problems with transients. Also thanks, will try to simulate it in spice!

Low side switching is not an option unfortunately. Are the N-fets a solution to the transistor voltage drop?

Also, do you think we should be looking for a replacement for the LM317 for future designs?

Thanks, I already solved it! I didn’t know that Drivers exist. The solution was to create a driver for each of the rgb color coordinates of the emitter, connect to a dmx channel and divide the value by 255.

I then connected to qlc+ using a virtual dmx channel and could control everything 😌

thanks, will look at the chain and frame too! (Doesn't seem to be that much rusty)

Thanks for the clear explanation, yes definitely broken then

what do you mean by "improper hole of the break lever"? Should it be small enough to pass just the metal cable and stop the thing between the metal cable and the plastic jacket?

First of all thank you for your answer! What I meant with animation is the light color modulation itself, so I would basically need to listen to incoming driver data and record it to play it afterwards as an animation (yes, we would export to usdz in order to import in reality composer).

Thanks for the detailed explanation, not the answer I hoped for but definitely the answer I needed! Will look into all 3 options, thanks again!

Thanks everyone for the answers, that’s really good news! I will try to plant some other edible things in my garden too now!

Thanks. J5 is 6 parallel jumpers to probe and adjust the current via RV[1-6]. J6 is connected to the laser diodes. As explained in another answer, we unfortunately must use a common ground.

They killed civilians. I have a friend who has a relative killed.

Thanks, very clear, that explains everything! I will buy new levers and I’ll bring the piece with me to check the hole size

Thanks for the detailed answer! We're doing a constant current source. The circuit you have linked would be perfect for future designs, but could a PMOS-FET be a drop-in replacement if we were to reuse the current PCBs we have? Do you have any suggestions on a specific model.
