Utilizing it is easy, strip the wires and solder it into your ciruitry. ... However,... If the batteries are nicad, then it may be, that the phone batteries had to be replaced because the pack is not holding its charge. The batteries could also have built up a memory, in which case, they will not di...

If you find that the power is dying more quickly than you anticipated, then yes, you can connect batteries in parallel to "make the gas tank bigger". As with batteries in series adding their voltage together, 6v 4ahr+6v 4ahr= 12v 4ahr... LED in series 2v+2v+2v = 6v.... so if using a six vo...

If you can use 0.60 acrylic rather than styrene, you might get better results.
All the styrene cuts I had kind of over melted, and sometimes curled.

Honestly,... only a few visible areas might need the level of detail that might be achieved by photo etching. The rest could be layered bits of styrene or acrylic built in a random manner. Say six to twelve inch long sections three to eight layers high. You could build practice pieces and when you g...

Hm. Perhaps I was wrong then. Wouldn't be the first time. :oops: Anyway, I just thought of something: airplane servos *can* be used, *if* you are willing to virtually destroy them. :wink: If you take off the casing and remove everything that isn't a motor or a gear, then connect the motor terminals...

The key seems to be in the mold temperature and
simple repetition. There will be flaws in any production run.

Aahh, but the flaws in metal casting can be thrown back
into the pot and melted down for another run.

Thanks Klywell any advice on the matter is much appreciated. Lt. Z0mBe, define "violently"... are we talking explosive...:D Has anyone had experience with the special Silicone they recommend? Anything funky about it or is it like every other silicone? Yes, especially in larger molds. any ...

You can buy "foam safe" CA.... Not sure where, and I have never used it... On wood frames, I typically tack the panels in place. weld the seam if possible, and then run CA into the frame/styrene joint from the back side. If a window has to be put in place later, you can't just flood the jo...

Let's Simplify this whole thing... I want to build X ship. At 1/1000 scale, the X ship builds out to 11 inches long... When I print out the drawing I found, it measures 3.375" long.... What percentage should the drawing be copied at to make it 1/1000 scale? 11 Inches is the ship at 1/1000, so 1...

My friend says it's an Arduino board... but that's certainly
not what I recall...

You want these... yeah... these are 1:75

The bulbs can be wired in parallel if one inverter can handle supplying both bulbs. Do not wire out put from the two inverters together... Be aware that the output from the inverters are AC, and up to 500 volts. The input to the inverters can be wired to the power source in parallel. Extending the l...

I draw an X across the point where I want the pin. Then extend the ends of the X onto the surface of the model.(arm/leg) The second piece is then held in place and the pencil marks are drawn across the joint.

In SoCal you're more likely to run across good foam in surfboards. If you can find a 'board maker, he'll have scraps left over (they cut the board shapes out of rectangular blocks of foam, so the 'corners' are discarded.) Not any more! The primary maker of the surfboard foam went out of business a ...

They don't insulate in California? Not in Southern California and at least not with blue/pink foam, or anything similar. The blue and pink foam that I have I got from a friend back in Astronomy; they bought several sheets to insulate some electronics, and they were "imported" from out of ...

I use the blue or pink styrene house insulation foam. Shape with a snap blade, and sand paper. Fiberglass using epoxy resins.

Your wiring set up as written needs about 16.4 volts. As written, you have wired the LED in series. If you want to use 6 volts, you will probably may need a 1/4 watt resistor in there at at least 150ohm, and all the LED should get their own positive and negative leads once the power enters the model...

Here's a build your own "servo tester" that can be used to
control a servo without a radio system.

http://www.pm.keirle.com/Servo/SERVO.HTM

Servos are not really stepper motors. As a servo turns, the gears inside also turn a potentiometer. The resistance feedback that the potentiometer provides then tells the servo board when to stop the motor. Now this known, if you just want to push a button to move the head left, or push a button to ...
