Finally getting back on this. I had to finish 2 studio scale x-wings before I could commit myself to working on the T-70.
I had to find a suitable power supply to power the Brickstuff screen. I wanted to use a battery pack onboard the model, so it took a little digging to find something suitable.
The Brickstuff screen requires a constant 5VDC, and draws approx 130mA.
I found a battery eliminator circuit on Amazon, that acts as a voltage regulator. I got 3 in a pack for like $8.
It’s pretty tiny. You can see a comparison next to a dime.
Input is 6-30VDC and output is either 5 or 9VDC, depending on how you set it up.
I used a 7.4VDC LiPO battery from a small R/C plane.
After wiring and soldering everything up, I verified the output was correct, then hooked it up to the Brickstuff screen....and fired it up.
The ‘magic smoke’ stayed inside the electronics...and the screen worked as designed!! Woohoo!!
Now, I’ll have to paint the cockpit interior, drill for fiber optics, and add some LEDs for additional effect.
