Here is what I used to push the clear cast to cure. Even the fast set stuff will not fully cure, if you are casting consoles and stuff, so it is better to get the slow set stuff and push the post cast cure, other wise you will have a lot of lost casting due to bubbles. (Fast set jells very fast prev...

There's some sticky threads at the top of this forum to help you get started, from where to buy stuff to basic blinking circuits.

Yes you will probably need to vacuum the oomoo, it is so thick post mix pre-cure that you will experience loss of detail on most [sci-fi] modeling applications if you don't vacuum the RTV after you mix it, and use some special pouring techniques to cover your masters. I used the oomoo in the beginni...

Stereo jack if you need 3 con...

Have you tested this wiring scheme? How did the LEDS look. I did the math: 150 ohms times 0.200 Amps and that one resistor is eating 30 volts. you probably calculated the resistor for one LED 150*0.020 mA and the resistor is eating 3 volts. But one resistor in line with all LEDs has to pass the curr...

don't forget in that configuration current is additive, so the current per LED * the number of LEDS will be passing through that one resistor.

You find out how many watts you're resistor is dissipating -> Resistance (in ohms) * current (in Amps)

no there are two buss that run the length of the board, the holes are there for you to insert a wire (from the other side this is the solder side) and then you have to solder the wire down. In any buss system you still need a mechanism to electrically and mechanically tie the wires into the buss. Wi...

you probably want a prototyping board similar to this:

Op amp blinking:

the circuit is linked to in one of the sticky threads

For slow pulsing lights, generated using the ramp up effect, try this:

I have some FX shots if you need some.

I was doing a search online yesterday for bulk sources of fiber too. How weird is that. I've ordered LEDs from a Chinese source before. Strip LED tape and some 'regular LEDs. They list both high quality and low quality LEDs in their vast catalog of LEDs. So you can get whatever suits your applicatio...

The previous diagram has been updated to remove ambiguity. Here's another one with more text descriptions: http://www.kc6sye.com/images/circuits/4060_how_tooo.jpg Here's the some text as well: Question? Does it matter which of the three 4017 "In" inputs connects to the three 4060 outputs (...

Something new form Zog: http://www.kc6sye.com/images/circuits/4060_+_4017_diagram_L.jpg a bit odd. Here's a way to multi-clock a 4017 chip (counts from 0 - 9) with a 4060 chip (self clocking with 12 divide by 2 outputs). Why? the several outputs from the 4060 change at different rates making the sca...

Just let us know what effect you want and we can figure out the circuits with you, or find a source that meets those needs.

I think you need to pm chautau, there is no public storage on the board, so he will have to email you the pictures/scans.

Ah its a bit tricky now, the main site is .com, while the forums are .net http://www.starshipmodeler.com/gallery/gallery.cfm You can search the gallery now for work submissions as well as for hobby shows that were reviewed. Its all under the general topic of galleries now. If you are looking for 'ho...

Something like this: http://www.electronickits.com/kit/complete/Automotive/VEK2599.htm But you will need a separate power supply for this unit, 12 volts dc. Most drop in replacements will need a Dc power supply, unless they have the power supply built into them. Search for electronic kits, there are...

http://www.electronickits.com/kit/complete/timers/canck002.htm You will have to figure out how much current the lights are using, this think is limited to 50 mA. If you need more and still need the drop in ready, you'll need to hunt some more. Also this circuit is not good fro the durations that the...

I think we figured (for the TOS) they rotated outwards from the ship. Careful review showed that there was possibly one light that flashed behind the fan blade type device that was actually spinning in the filming model. That was one of the several other lights that appear as single light sources. I...

I found a little info on the props, there's the Master Replicas picture of an 'OSX' tricorder a limited picture is shown of this on one of their product pages. I'm think this is the Mark 10 that you are working on. Another website showed the medical tricorder: http://www.star-trek-voyager.net/ship4/...

Shucks, I don't have any DVDs from Voyager, and only caught a few of those as-well. If there is a lot of actions, and you might want some feedback buttons to start and stop them, a micro controller will be you're best bet. there are a few guys here that can do that for you (write the program and loa...

It sounds like this is a kit you got somewhere. I'm not familiar with it so we'll need pics or other references to the prop you're trying to reproduce. I'm guessing it is a Star Trek tricorder you're talking about. Is this the Original Series, Next Gen, Deep Space Nine, or Voyager. I don't remember ...

Blappy did a handout ofr 2005 wonderfest class on mastering for casting.... http://www.starshipmodeler.info/wfest2k5/handout_WonderfestHandout2005.pdf hollow casting can be done by hand for short production runs, and saves both on resin and life of the mold (thicker resin gets very hot) homebrew ele...

A regular pencil lead will conduct great in the right application. We used construction pencils as spark gaps (the thick flat kind). And I tried to use a pencil to move an electrode once, it was not as insulative as I'd planned, by the feel of it the spark came down the pencil lead to the medal eras...

any ideas on how to do welds? Tamyia tanks have this effect, just wondering if there's some trick to reproducing it.

Never mind I see it now in that link. . .

The tape I got was from the stain glass supplies section at hobby lobby. I had to slice it down since they didn't have narrower strips. Also the sticky was better at handling heat than the proper width copper tape I got from the circuit board repair section at the electronics store.

and if you can do a mock up with the light in place on the model, you can work empirically towards getting the effect you want, with the micro controller. With the 4060 I just to whack at the connections with the pin header till it looked like an antenna tower strobe. There's no guarantee that you c...

Are you talking about the strobe we used for the Sub space antenna array? This Zogs generic circuit, I think its in the sticky This circuit: http://kc6sye.com/techmages_11_10_06.html Its on the left of board (top view) right of the board (solder side view) Its a very down and dirty way to play with ...

There is an epoxy glue filled with nickle fillings, note that you have to wait for it to dry. It is none conductive prior to curing. Also super glue is a great insulator, had some issues with gluing surface mount leds down then soldering to them, caused by the glue dripping over the pads. Had to sol...

Maybe that is also why the green led's have a lower mcd rating compared to the red from the same line up (I did a quick search on digikey)? The marked advantage to making sure they are the same current is that you can put them in series rather than in parallel. The take away note, is get red and gre...
