Starship Modeler Discussion Forums

Just printed out this topic, starting my Wonderfest shopping list

On the way!

As far as Newport Tenn. after a battle on the Interstate.
Two major construction related traffic delays totaling over 3 hours of delays.

However, will be there and looking forward to seeing everyone.

The wife and I are finalizing reservations the next two days and will be there.

Any openings on an Iron modeler team?
I have the bag of miscellaneous parts for the entry fee.

We are REALLY looking forward to seeing everyone.

Paula and I picked up our team's entry.
We also picked us the entry for Two Guys and a Broad.
Both safely made it home and if Two Guys and a Broad would like their entry we will pack and ship it to them.
Just send me a private message and we can arrange shipping.

Thanks.

BGuy,

No problem, if you check my first post in this topic I already have a big bag of parts for the "entry fee".
Also I am driving so bringing them is no issue.
I might still take you up on the drink

Starting to pack, getting excited.

See you (sort of) soon.

Love it.
I couldn't get a confirmation of the registration.
Messages OneZero, no reply yet.
I will try to register with the new name now.

BGuy, As far as I know there are no restrictions on forming teams. Since you and I are both looking to participate and a minimum teams is is 2, Looks like we have a team if that is OK with you. If you are OK with it I will sign up the team with the name Starfury Pilots. If you have a better idea for...

Any teams looking for a member? For those who don't recognize the "handle" I have been on the board for a while and have attended several Iron Modelers. One team I was on won Best Use of Greeblies in 2012. I have the "entry fee" ready to bring with me. Just reply or PM me. I trie...

LEDs are not linear devices, they do not act like resistors e.g if you drop the voltage 10% the current does not drop by 10%. The LED needs 3.3 volts and before current starts to flow and an additional component is needed to limit the current to 20 ma. So if you want to use 3 - 1.5v batteries (4.5 v...

If you want an inexpensive source for large versions of the magnets look for "dead" hard drives. You need to tear them apart CAREFULLY however there are usually 2 large magnets in each drive. I have had people "donate" their dead drives to me, since I assured them the data would ...

you are drawing heated plastic around what ever your master is. would you be able to vac form over a styrene kit part? or would it melt/warp/damage it? and resin doesn't like heat either what about it? is the forming process quick enough that the plastic cools before it can really do andy harm? i'v...

I have built booths with airflow going vertical and horizontal they worked equally well. However I filter the air coming in and going out and wipe down the booth before spraying. Just my 2 cents.

The red LEDs have a different voltage and current requirements. Based on what I could find the red LEDs should be brighter then the blue and white, so I must have missed something. Could you list the specs, voltage and current of the red, blue and white LEDs? Are the red LEDs brighter at the LED and...

It is entirely possible the wall wort was not supplying clean power.
This could have caused damage to other components.
That might explain why the 555s keep frying.

I'm in, I can consider Wonderfest a warm up.

I think I understand the question. I am working on a similar circuit myself. If I understand correctly, you need to determine the frequency and the duty cycle. Using Kylwell's input as a standard if you set the frequency to 80 htz (72 + 10% approx.) as you reduce the duty cycle to give the impressio...

John, Can you define "too slow". IIRC anything over 15 cycles per second is going to have issues. If you are running slower than that it could be a duty cycle issue. If the LED is on over 50% of the time there will also be and issue. Any details .e.g. the basic circuit (555 or PIC) would a...

I have picked my sheets up at model railroad shops. The RR hobbyists use it for billboards, street signs, and building lights.

Great stuff.

I have never been able to successfully make new connections to a sheet.
That isn't to say it can't be done.

See, this is why I look to you all FIRST.
(especially after the hot water/sprey can incident)

THANKS

Jammies

Excellent idea.
I'll have to give this a try.

Can you give some more details, e.g. how many "lights" do you want, blinking, sequenced, etc.

Thanks

Just a comment on the calculations, one of my B5 references mentions that the maximum gravity on B5 was .9 earth (in the areas normally inhabited, not the outer limit of the hull). The difference in diameter and max g would help explain the difference in rotation speed. (Interesting that it appears ...

I have heard of adding a couple drops of blue to the white to make it whiter.
Not that I understand how this works but it does.

Just my 2 ducats.

As a last resort, find a smooth wire smaller that you want the hose e.g. 12 or 14 ga. house wiring. Wrap the outside with smaller wire e.g. 18 or 20 ga. couple drops of super glue along the way, quick paint job and viola.

I keep a honing stone in my tool kit and dress my blades before I make and critical cuts, even the new blades.


Just my 2 cents.

I have a can of mold release I bought when I picked up my first Alumalite kit. I have been through several bulk packs of casting resin and still have the same can, it only takes a light dusting. I just checked the basement to get the name and I can't find it right now. Check with the store where you...

Just a suggestion, and not the best one but it should work. I assume you are using pins 1 - 7 , 9, 11 and 12 as the count pins. Cascade "OR" gates and an inverter so the output goes true when all outputs are low (0) and use that signal to drive the 11th LED. Bit of a pain and there is a wa...

According to the national standards 28 ga. is good for 1.4 amps (1400 mils) 30 LEDs should draw around 600 mils, "room to spare". If you are using a wall wart check if it can supply that much current.

Joe

No it isn't, not for me. Thanks for that idea Irishtrek. It is which is now filed in teh metal "tool box" .

Are you really planning t install 500 leds in one model? At 20 mils each thats 10 amps. 20 guage would be needed to handle the load. That also means you need to vent the heat created by 50 watts of power. Check your power supply also, a wall wart isn't going to handle that kind of load. If you are o...

I use a spray booth with charcol filters and I also use one of the dual cartridge masks. Also make sure you get the correct filter for the mask. Mine came with a dust filter, the vapor (?) filters were extra, I think they contain carbon.
