Okay - I just had a thought:

If I used a circuit for flashing a single LED, then I can use a transistor to blink as many LEDs in parallel as I need.

I just need to find a flasher circuit that runs at 4.5v.

(Most of the circuits I’ve seen have been 9-12v.)

Adafruit makes an Arduino Trinket:

$8.95 + shipping.

Hello Braintrust!

Does anyone know of a (simple) circuit for blinking two (or more) LEDs on and off at the same time?

I know I could do this with an Arduino, but in this case I’m hoping to avoid the expense.

Any help would be appreciated!

Thanks!

Hello Everyone, Over the years I've become afraid of the decaling process. I've read lots of horror stories on this site, and I've somehow managed to stay away from this all important step. But I've been working on the Bandai Star Wars Tie Advanced and Tie Fighter models, and before I can seal up th...

I have it too. I replaced the plastic bearings with Tamiya RC car bearings. Also the Dremel collets fit nicely and work for the 60-80 size bits. Which Dremel collets are you using? The ones I have are too small to work in my Handy Drill without an adapter. The included Tamiya collets measure 5.97 m...

By “too small,” I mean that the diameter of the Dremel collets is smaller than the diameter of the collets supplied with the Tamiya Handy Drill. The included Tamiya collets measure 5.97 mm / 0.235 inch in diameter, while the Dremel collets are 4.34 mm / 0.171 inch in diameter. Thanks for the link! I...

I have the drill, and put it together without too much trouble.

However, I was disappointed to find out that Dremel collets are too small to work.

Can anyone recommend a collet set that would work with a #80 bit?

The Handy Drill runs at about 800 RPM (due to the gearing) and the Router runs at about 1400 RPM. I have used both for drilling plastic going as small as a #80 bit. The trick is to place the drill bit exactly where you want the hole, then hit the trigger. The drill bit should pull itself into the p...

Don't bother. It's a very handy drill as it is. The speed is reasonably slow and I'll say it's just about perfect for drilling through plastic. That's what it was designed to do, and it does it very well. Everything inside it is plastic, even the gears, so making it spin faster would shorten the li...

I just ordered the Tamiya Handy Drill.

Has anyone tried modifying the drill by adding a potentiometer to be able to vary the speed?

Thanks for the tips!

I just painted some styrene model parts with Tamiya Acrylic paint, but I’ve decided that the color is too dark, so I’d like to strip and repaint.

What would be the best way of removing the paint?

Any insight would be appreciated!

Did you dilute the paint at all?

If you have any spare pippets around, this might be the way to go:

In Gary Kerr’s article on the color of the TOS Enterprise: https://culttvman.com/main/a-modelers-guide-to-painting-the-starship-enterprise-by-gary-kerr/ He describes the pilot defelector dish color as “The larger Pilot version dish was a dull, weathered copper color, similar to an old penny...” Does...

It was by the TVs, along with magnetic phone mounts and charging cables.

They had a cardboard display with bins for different products.

Hello Braintrust: FYI: I stopped in Wal-Mart the other day with my Aunt, because she wanted to set up a Roku in her guest bedroom. Anyways I found this: https://i.imgur.com/YaVNje0.jpg For $4.99 you get 6 1/2 feet of LED strip lighting with 60 RGB LEDs, along with a remote, and a USB connector. I en...

Just picked this up from Adafruit:

It’ll be fun to learn new ways of using LEDs!

All good suggestions, thanks!

I’ve ordered a breadboard and will start by playing with the resistors I have on hand.

Hey Everyone, I've been working on putting together my first model using LEDs and fiber optics. (I'm almost ashamed to admit that I've played around with both over the years, but never actually committed myself to completing a project using these components.) I've been working using Round 2's recent...

Thanks for the suggestions! I would love to learn Arduino programming, but of course it boils down to time. I've decided to go with a self-flashing LED, and then run fiber optic to my three spots. This seems to be the simplest way to go. https://www.dropbox.com/s/6kcgxv6jctjv9ds/LED_Flash.MOV?dl=0 C...

Cool!

Thanks!

I recently found a small bag with 50 3mm LEDs when I was digging through a closet. They're water-clear, so I don't know know what color they are. I know that red/yellow LEDs typically are 2.2V, while white LEDs are 3.3V. Any suggestions on how I can tell what they are? (And yes, I do have a digital ...

Thanks for the reply!

In the past, I’ve used this kit from All Electronics:

https://www.allelectronics.com/item/led ... kit/1.html

That would work, if I could figure out how to add an extra LED. Maybe wire a resistor an an LED in parallel with one of the LEDs already on the board?

Hey Braintrust,

I’m looking for an LED blinking circuit that will flash three LEDs at the same time. The circuit should be able to drive 3.0-3.3v white LEDs.

Any suggestions would be appreciated!

Adafruit and Sparkfun are two my favorite websites:

But if you really want to make your head swim with a dizzying number of choices, head over to Digi-Key:

I guess utilizing the technology used by the C.M.D.F. is out of the question? If you have seen "Innerspace" you will know that the guy with that technology and the drill... (SPOILER ALERT->) came to a bad end (<-/ Spoiler Alert) As a more constructive note, you may need to mark and count ...

Thanks! I’ll take a look at what I have in the way of heat shrink tubing. It’s definitely worth a shot.

I should add that there are two hex screws on the chuck, positioned opposite from one another.

But trying to screw them in so that they’re equidistant from one another has been a challenge...

IMHO, Widget Supply is the best value for the money when it comes to drill bits:
