Bling, Bling!

The beauty is that this will run off the same 1.2V supply as the rest of the car. No extra batteries.....

Nice dude... How will it affect the run time? Are the Light tinted or yellow leds?

nice ph2t!
lookin great so far, the finished car is gonna look dope!

yea, give us some details. lol

They are yellow surface mount LED's. I wanted a design that didn't cut holes in the shell. I'm looking for white/blue surface mount LED's but my local electronics store is selling 6 of 'em for $16 AUS!!!!! @#^& rip off!

Sorry jowlz I have no idea what you're talkin about man....

There is a chip on the RX pcb that converts 1.2V to 3V. It is what the RX2 chip uses to get its power from since the minimum operating voltage is 2.4V for these chips. I can use this chip to drive the LEDs....

Looking good ph2t.
I lack the electronics knowledge to do this, and I won't pay much for it but you should ahve a go at this light mod -

Nate dogg and warren g are "rap artists", I think one of em is snoop dogg's cousin.

now that's biatch!

Payaso, forget to say that yes it will affect runtime since the lights will add extra current drain on top of the normal pcb, but with 150mAh+ cells and better chargers out there it shouldn't be an issue. The basic rule is the brighter the LEDs (mcd value, these leds are not that bright, only 20-40mcd, the blue 3mm ones go up to 1200mcd!!) the more current they'll suck.

Sessiz, yeh that light mod is from "mikes mods" page. A couple of us techies at ausmicro are trying to reverse engineer the thing to find out what makes it tick. I want to be able to do the same things but be able to source all the parts for it from a clone PCB. This is where the 1.2V -> 3V convertor is coming from. I tried using the 3V source that is on the pcb already but found that the current drain brought the voltage down to below 2.4V causing the RX2 chip to switch off. Using a seperate voltage converter chip from a clone shouln't affect the 3V rail that's on the pcb running the RX2 chip....

Well I started pulling apart one of my clone PCB's to use the SMT stuff on there, including some transistors and some resistors. I had some other old Hard Disk circuit boards lying around so I ripped some SMT capacitors of them as well as some more resistors....

With all that farting around I made this.....

There's a bit there, you can see two great big caps at the front, then a couple of black rectangular transistors (ripped from the steering circuit on the RX pcb) and so on.... The two white clearlike things are the LED's.

Here's a side on picture to help go with the explanation....

As you can see it is built on ordinary vero board, nuthin' fancy...

It's small too. I want the circuitry to be able to fit in the roof of the car's shell. I've got a bit more to cram in though including on/off controll for headlights, control for left/right indicators, rear brake lights, etc, etc...

Shown next to a Bensu clone pcb for size comparison.

This is just the flasher circuit, when final it won't alternate the flashing of the indicators since only one indicator will be on for the turn you make, a bit to go yet.

Here's a video of said work.....

Very impressive dude... You're making me want lights now damnit...lol

Well, I storta killed the LED flasher board that I had posted earlier in this thread so I went ahead and made a new one. I finally got off my but and completed the indicator lights.

Here's a pic of the final prototype: Can you spot the LED's?

FRONT

REAR

Here's all the crap I managed to stick under the RX-7 case...... A fair bit goes in there.

Basically the extra pcb I put in connects to V+ & V- of the RX pcb along with the BASE side of the Left and Right steering transistors.

Here's some video.

On the test bench

Night running 1

Night running 2

The LEDS aren't as bright as I'd like them to be, but I can fix that with some more development later.

Well stage 1 done, now for stages 2 and 3!!!!!!!!!!!
