Why do this to yourself? Meanwhile I'm laying 50 stupidly small fiber optic cables that I never planned for. This 1/1000 piece of .... is busting at the seams.

Glad to help you save time with some tips. This should be a breeze for you. Get yourself an Uno R3 Starter kit with a selection of electronic parts, and you should be good to go. Then you can follow some Learn Arduino tutorials. Start at Lesson 0. It should take you no more than a few minutes to set it up and have a few sketches working.

That's what I keep hearing. Is it recommended to decant Krylon primer?

Has anyone had a problem with Vallejo Air Primer peeling off with masking tape? Just checking before I commit.

From the very first post in this thread. Seems to have been a very reliable source.

How do I calculate what size battery I need, 100, 500, or 1200 mAh? I have, say, 300ma servo, 100ma SD Card, 20ma leds, 4ma amp, and an 8ohm speaker. So I approximate that a 500mAH battery will run this for an hour. I've switched over the entire sketch from the Arduino Uno board to the miniature Trinket Pro. Wow, went off without a hitch. The pin numbers and functions are all the same and no special code was required. I've got 16 data pins running leds, sound and servos from a 4cm board. Call me surprised. Two lessons here: 1. Arduino is idiot proof 2. You can learn anything on Youtube

Good point. Frontier valks may be too complicated for 1/100. Would it have to be a complete rethink of the transformation? Still would be nice to see the sleek VF-25s in this scale.

I think there is a high probability we will see Frontier HMR. But we need to concentrate on SDF now. Bend Bandai to our will.

Don't say it. My poor wallet.

It is at least a unique concept. I want to see it. But: Aoshima + Model kit + Transforming Valk + Armored Figure? This wont end well.

After extreme dremmeling, I got a nice comfortable fit of the Trinket Pro, the servo and all the wires in the rear. I can't keep those thick wires, so I have to decide whether to link them to magnet wire, or if its better to solder magnet wire directly to the Trinket.

Beautiful. Those require two things I don't have: Money and skill.

Who's to say there are not two different armor types: White and Gray...and they used them in different scenes? There is also the issue of color palette in space, versus under blue sky, versus under water (Thinking Blue Noah, Nautilus and Yamato).

I use the Masking Sol. But I find it doesnt stick well enough and flakes off easily.

Check out final sketch above. Still awaiting better amp and speaker.

Success! I was able to work sound, LEDs, and servos into my sketch using the TMRpcm library. I found out Servos don't work with SD cards, so I used detach/attach servos before sound to solve the problem. One of my servos seems to be starting at the wrong point...

I'm an electronics genius. LMAO.

Could you direct me to your smaller servo? And please check my corrections in the question above. Thx.

Also need your help for replacing the transistor in This example with a better amplifier breakout. Will this Class D amp work?. To replace the transistor with the amp, I think I need to connect as follows: A+ to Arduino pin A- to Gnd Vin to 5v Gnd to Gnd Please let me know if you think this will burn anything out before I try.

I'd love to see a photo of the insides. Dont know how you fit all that in there.

No problem. But this is how I measure them with a ruler: 22mm H x 20mm W x 8mm Deep These measurements are without the tabs.

The stated Dimensions are correct. I cannot measure with better accuracy. Dimensions: 19.6 x 8.20 x 19.50mm

Actually i dont know if its digital or analog. I dont even know if itsa continuous type or not. It works with the Uno if you recall my turret servo sweep on the Yamato. The servo specs are here. The Trinket cant run a servo without a potentiometer. I was just testing direct signal as with Uno to see what happens. Maybe I damaged it. When i reconected to Uno, it continued to spin non-stop, but my other servos were fine.

I was using the normal 5v Trinket, not the Pro Trinket. The servo here is also 5v. Smallest I could find. I assume its analog. When I hooked it up to the Trinket on the PWM pin, it started spinning non-stop.

Whoaaah!
