Yeah microcontrollers are the way to go, no question there. I need to find the time to go through the learning curve and get away from complex circuits. The transistor was the problem in the end, I swapped it out for another and it worked fine...must have had a bad one in the bunch or something. The...

A higher voltage rating on a cap is fine: the voltage rating is just how many volts you can put across the terminals before it explodes. It's hard to diagnose just what's going on with the circuit, but it helps to understand how the circuit is supposed to work: The 555 is being used to generate a c...

I need help from you experts!! I've built up a circuit on a breadboard to get the double strobe flash for the JJprise using a schematic I downloaded a few years ago, but it's not doing what I expected. Here's a link to the schematic: http://i546.photobucket.com/albums/hh420/OftenwrongSoong/Avatars/D...

...Check out Soongs Enterprise D...I'd rake my eyes with a melon scoop if I had to mask all that. Crazy. Haha! yep, crazy I whole heartedly agree buddy! The next one will be 2 colours only...and a 1/1000 scratchbuild... :twisted: As for aztecing, depends on your experience/skill with an airbrush. I...

Well I've only built 3 models so far so I'm not really qualified to comment really but I tried both techniques and found that painting as a whole works best for me so far. I built an Enterprise D and only painted after all of the construction was complete, that way I could be sure that all of the se...

I've still got a LM3909 in my stash but since I needed 2 seperate strobe rates I thought I'd try to use some parts I already have rather than track down more LM3909's online. This is the schematic I settled on, I used a 50k Pot for R2 so I can adjust the rate http://i546.photobucket.com/albums/hh42...

That's exactly it Wrong - with one small addition Check THIS for the schematic and THIS for the vid of the result Vary R5 and R4 to get the timing - but keep R4's value well below R5's Leave the Diode in, that's how you get the quick on-off of a strobe effect from a 555 Awesome cheers Ken, i'll giv...

You could use a 556 chip - two separate 555's in one little plastic bug. Or the CMOS equivalent to save much power. Yeah, thought about that but im not too good with this stuff and wasnt sure how to get the strobe flash 'abrupt' enough with a 555/6. Is it just a case of getting the right capacitors...

Hi guys, I need a bit of help with a strobe circuit for my Ent E. Is there a way of having 2 sets of strobes flashing at different rates on the same circuit, and have the rates adjustable? I want to avoid pic's and LM3909's if possible. If not, what IC is a good/better alternative to the LM3909? Che...

Any chance I could have a copy of the schematic?? I'll PM you just in case

I think so. But then I've been programming them for a while. It doesn't hurt that the average one that you will use for this sort of thing only has around 35 instructions (and you will only use a third of them). I do some extremely complicated things with them. For examples, see the VoodooFX websit...

Gonna have to give myself a crach course in PIC's, seems like they're FAR easier to use once you're over the learning curve

Dude, i'm in the UK too. Any chance you could give me your sources?

Yeah thats true, those tiny guys are REALLY fragile! You'd need a very fine tip on your iron and, as mhvink says, you gotta use the heat very sparingly. I used to remove surface mounted IC's using a stereo microscope in my old job and spend forever trying to replace damaged or burned out components ...
