Am I giving these things too much voltage and will they burn out quickly? If I need a resistor in there what should I use to extend the life of the LEDs but still get decent brightness? What are the part numbers / datasheets of your two blue LEDs? You need to check that you're not exceeding the max...

Some more circuit ideas from Zog. Some simple LED drivers, and help with transistor boosting for more LED driving power. <A HREF="http://www.kc6sye.com/images/circuits/transistor_drivers_CMOS.jpg" target="_blank">Transistor Drivers and CMOS</A> Going through all of Zog's circuit...

You'll have to be very patient then. I watched a green stuff master saw a metal model once and it is very tedious... I avoid converting metal models like the plague. As I said, maybe it is worthwhile waiting for your model to come out in Finecast which will be easier to saw / mod. To give you an ide...

I am really excited... I just got my electronics to put fibre into my grav tanks. As some trying to do Eldar, I can identify with the last poster's question. You'd have to pray it's a plastic kit (or Finecast now, yay!) and NOT metal saw it in half, drill it out and install the electronics. You'll n...

I have plans to use the nano as well for prototyping;
that is in my kit list

that currently needs more money to complete; working on painting my existing kits at the moment while I save.

5 x Wave Serpent Grav Tank (Games Workshop)
3 x Fire Prism Grav Tank (Games Workshop)

lol
I don't suppose they are on your list?


I have an old trek kit as well but that's a bit lower on my list

much obliged ufd108

Did you place in the competition?? wow show us some photos of your paint job ... :D Just got back from a model contest and even though I did place in the two categories I entered in I came up short against models that had some kind of lighting package. After talking to some of the judges the general...

Breadboard is a great idea

Start small, connect a battery, resistor and LED on your breadboard
slowly work up until you have the entire circuit put together.




The flasher may be tougher but get the breadboard and the basic ones done first. Then we can talk about hooking up the flasher.

Start with what you want to achieve first, then move back and decide what components you need. What model are you fitting it to? Do you need a simple light that is always on, attached to a battery? Do you need it to blink, or a complex light pattern? Tell us what you are planning first in detail rat...

The site also has 5mm LEDs in the 13 degree high brightness variety?

The right tool for the right job....

Thankyou!

I am looking at the coolrunner CPLD, 32 pin package. I remember working for an electronics company where a hardware engineer used it to control a fan.

Hey guys, I was thinking of using VHDL and field programmable grid arrays, instead of buying a whole load of SR latches for complex lighting patterns. Is there a recommended one that is easy to plug into a bread board? As an aside I'm looking for the "burn to flash" variety that persists a...

For compact / mobile applications, there are a new generation of Lithium Ion batteries. You need a charger, however, to recharge them. There are also smaller. non re-chargable versions. http://www.protogear.com.au/product_info.php?products_id=100165 http://www.protogear.com.au/product_info.php?produ...

I am glad I found this place. You guys are a wellspring of knowledge and I hope one day I can give back. EDIT : Tetsujin if the connector isn't snappable is a sharp scalpal / modelling knife the best way for a clean cut? It may sound obvious but I'm wondering why it being snappable matters or not, o...

Might I ask that we may find a means to profit from your hard work, creativity and ingenuity. Originally I planned to have only LEDs in the model so that I could store the microcontroller on the outside (an Arduino mini)? in a scenic base. But seeing as you have a 11mm x 10mm PIC controller board ma...

Thank you sir; very much obliged. I'm still learning how to navigate the Jameco site. I'm going to order in some of these connectors so I can block it out on my model kits before drilling holes Thanks again. Ok .50-.60 each Misc connectors What you're looking for is #4 (male), #9 (RA Female) and #14...

What category in Jameco are they filed under?

USS Atlantis wrote:And Jameco has multi-conductor mini-flat plugs (the type your PC's Sound Board connects to the DVD/CD with) for 0.30-0.50 each - 2-12 conductor

Those prices are really high

Sorry , posted in wrong topic

Hmm the challenge is now to design a flying base that isn't bulky to house the batteries / electronics... working on that now... EDIT: After seeing this thread http://www.starshipmodeler.net/talk/viewtopic.php?t=89657&sid=533a1542d28101cf65eb670770145718 I have decided that the only item that sh...

On the contrary I welcome Tetsujin's comparison
Most of the items that Tetsujin advised are already in the sticky threads

If you're on the Internet you should stack up to your competitors
and I'm glad he did the shopping around for me

I also thank you too; it's always good to see alternatives

Wow their margin is a bit high

but those mini connectors look nice....


PS: You can buy pre-soldered SMT LEDs from HLJ??!? WOW
Do you have a link for that?

Here is a better image... notice the clear base... http://img234.imageshack.us/img234/9408/falcon1mo.jpg These are on a tabletop battlefield so power has to be self-contained.

Gents I'm working on various grav tank kits: http://www.games-workshop.com/gws/catalog/productDetail.jsp?catId=cat440172a&prodId=prod1090170&rootCatGameStyle= The inside is quite small and I need to squeeze a battery with enough voltage inside to at least light the engines and the cockpit. h...

Just received my optics. The hobby spool is very small but suitable for my purposes. They also attached a samples kit which is very cool.

And they haven't spammed me yet !

Recommended.

Was wondering what the best way to bore the hole to terminate the fibre end is? I have a hobby drill.

I'm doing the Falcon Grav Tank kit and it has raised buttons so I'm concerned as to how to get the optics to look good

Looking for a source of 0402 SMT LEDs as mentioned in this thread:
http://www.starshipmodeler.net/talk/vie ... hp?t=86200

Trawling the suggested links it's hard to find the text string "0402"

I just bought a spool from them. Will let you know if I receive it.

PS: I'm in OZ.
