Finally i got working blinkers!!!! I ain’t got video yet but I will soon and you will all see them working.

For micro, jamie, GT and other likeminded electronics freaks this is the circuit I designed for it.

The left side is your basic LED flasher circuit. I’ve added a couple of transistors to be able to select which LED flashes based on the signal coming from the RX pcb.

I’m not cookin’ so it prolly will be good, lol!

Good stuff…. Now if only my Nokia 8250 could order pizza, THAT would be progress…….

😀

Micro, an interesting side note:

Traditionally, when the car reaches that stage that it won’t move any further you could lift the car up off the ground and it would continue on for a little while (with no load) before dying completely.

Now (post FET mod), that stage of the battery drain allows you to continue driving the car around on the floor. The increase in current gives the motor enough tourque to be able to move under normal load. Ive gotten an extra 30-45 seconds runtime due to the extra current at the end-of-life charge.

So the irony here is that whilst the theoretical runtime is decrease due to increased current drain on the batt, it is practically increased due to the extra current available in the last stages……

Cheers,

Always *subtle* aren’t ya Barrell, lol! :smiley16:

I got my 27Mhz S2000 Compact back from Micro yesterday and I can only say one thing. WOOOOOW! This mod rocks! I can’t say that enough. At first I put back in a 2.2 that came stock with the car when I bought it. The 2.2 with the FET mod takes off faster than my 40Mhz Compact with a perfection 3.8. I then put the perfection 3.8 in the FET modded car and I gotta say that it leaves my clone dual batt with a 2.6 for dead!

The FET modded car has the following after market mods:

FET Mod.
3.8 perfection motor
Bit Racer Soft front and rear tyres.
Crip cap (in the car) mod and longer antenna.

I run this car on polished floorboards so the soft tyres were the go. Taking a corner keeps the car on the ground. On carpet the car requires hard tyres for the front end or it will flip ( this even happened with the 2.2 stock motor!!!)

I gotta say that if you can get this mod done DO IT. Micro had my car back within 2 days, in great packaging and all the original parts. (The trasnsistors that were replaced are useful for a techo like me, Micro gave me the option which is great.)

I will be getting all my cars modded to suit. I will also take some video showing the results of this mod, watch this space!

Excellent job micro, Kudos!
:D:D:D

Micro, I wish. Probably more “stuff” for the house like pot plants ‘n crap like that.

Thanks Barto…

:approve:

[ph2t]

Could be the eye candy factor, cut short to look cool. Who knows, they might of been able to make the RX soooo sensitive that a shorter antenna is possible. Will know more when these suckers come out….

[ph2t]

Good stuff man, just don’t tell anyone where I live……:approve:

[ph2t]

8ch, I was thinking about using heatshrink, but I dunno……

[ph2t]

Micro, got me a Lxx booster(57mhz), a 3.8 and two tire sets(non coloured).

Depending on the Lxx quality I was gonna put the pcb in my MS RX-7 27Mhz chassis. I just wanted to get a booster. Was thinking of doing a proper dual cell for once.

And of course there is the package you dropped off for me today! :approve:

[ph2t]

I’m cheap and easy, lol!:p

[ph2t]

Yeah, that was the meaning in my head, I guess it didn’t translate to my fingers, doh!

[ph2t]

You’re gonna have to invent a new type of tyre that will stick to the road enough. All this extra power with no where to grip, arghhh!:evil:

[ph2t]

The RX2 chip can sustain up to a 6V source. This is academic considering that there is a 3V DC regulator chip that always outputs 3V when the input can vary from 1.2V to 6V. As jamie said, the motor will prolly die first…. Make sure you’ve got a few spare, lol!

ph2t.

[ph2t]

Panda, can you send me that design info. Would be good to *cough* know *cough*….

:smiley16:

ph2t.

[ph2t]

Whooo, yeah, come on!!!!!

Can’t wait….
:p:p:p

[ph2t]

Good suggestion, I might just give this ago.

I tried softening up the plastic sheathing from some hobby wire and stretching it over the axle but it kept breaking, arghhhhh!

[ph2t]

Can’t wait for my S2000 to come back from Micro’s chop shop… lol!

[ph2t]

Yup. They have several payment options…

[ph2t]

Just got my package today. So that was a 7 day turnaround. Not bad I gotta say. Similar packages from the US have taken up to 9 days….

Now to find some AA batteries……:approve:

ph2t.

[ph2t]

Yeah I’ve seen tham as well man but I think the shells are just a few centimeters too long. The rims are pretty nice though.

[ph2t]

Thanks, once I gat all the elctonics in order I’ll start fitting it to the shell. Should be pretty funky once it’s finished. :p

[ph2t]

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 off 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 control 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…..
