The goal is to have a lighted robot without an external source. Which led me to an experiment, because resistor calculators don't do it: I put a green, a blue, and a red on a 3v coin cell. I slowly increased the resistors for each by trial and error until I got balanced power with no one led sapping light from the others. In this case I gave 270 and 680 Oms for the green and the red, and 47 Ohms for the blue. This set up has been running steady for a couple hours now.

It's true for same color leds, but not for mixed colors. I made this demo to explain what I am trying to do.

More Elvis jokes please.

One thing I haven't figured out yet is how to power multiple leds with one 3v coin cell battery. Most tutorials say it cant be done. But, for example Bandai's Patlabor runs over 6 flashing leds off a coin cell and I've seen kids toys do it. I've tried parallel, I've tried serial, the battery runs out in a matter of seconds.

My other projects are here. Good question. The power is the main issue when starting out. You have to forget everything you think you know and start form scratch. In this case, I needed an external source because using three different colors is a big drag on the batteries, and also a drag on space because you need a resistor for each led in parallel, or a serial circuit calculation. We can happily answer all your questions on a specific thread for electronics here. Its very easy if you get the right help.

I wasnt planning on a second Drakken, but that Elvis Valk is too sick.
-
This was my first LED project from a couple years ago.
-
Full wiring setup ready for the Nautilus. Everything here will be installed in the model after I finish painting. Lights, speaker, amp, SD card, motor, battery, charger, and switches all playing nicely together.

Good question. I'm not trolling, this is my honest opinion. Favorites: Too many favorites. Cannot pick just three. Least Favorite: Yamato 1/60 VF-1 V1. The parts-former made me swear off Macross toys for 10 years.

Can you share the file for your build, or are you keeping it confidential?
-
Testing some different lighting with colored and plain clear coats on my resin cast. I need that crystal resin!
-
Is this it by any chance?
-
Great casting clear parts! I wish I could do as well. Could you indicate the resin and mold material you used?
-
Got my kids into the software. They google instructions for their favorite kits and then try to build them. They love it, but lots of parts are not included.
-
Great work. You nailed it! You should submit it to Lego website for voting to actually get it made. A transforming valk made it through the first rounds at Lego, but seemed too gaudy to me and maybe not a workable toy. Maybe yours could make it.
-
So amazing. I hope we will see lots more photoshoots of your diorama with HM-R.
-
OMG!
-
hmmm... makes sense now.
-
Some unique skills there Pengbuzz. I think you could try sculpting.
-
Those Bandai Star Wars kits have a lot of detail. But my eye is on that gray vf-31!
-
A little update for those not on the Workbench. Got the motor working!
-
After 5 tries, finally got a good mold!
-
Guld really took one for the team.
-
Finished some detailing. Looks like a duck! Struggling to mold some tiny clear eye holes for the bridge. Lets see how that works out.
-
I believe there is a 1/60 Ex-Gear pilot with the DX VF-25.
