## Introduction: How to Build a Simple Solderless Circuit.

Hello again! This is Craft Maker Infinity doing another collaboration with JM1999! :)

In this instructable, JM1999 will be showing you how to make a simple, solderless circuit! (BTW I used to try to make these, but they didn't turn out so good, but JM1999 has figured out how to do it in a much easier way!) ;3

## Step 1: How to Make It

What you will need is:

One 9 volt battery, two copper wires (about 3 inches long each), scissors (or a wire stripper), PVC electrical insulation tape (Tradeforce brand is what JM1999 uses here), an LED Light emitting diode (make sure it has the posts, which are the two rod-like wires sticking out), and a 510 ohm resistor (Green-Brown-Brown).

## Step 2: And You're Done!

Once again, thank you JM1999 for his part in this instructable, and for coming up with such a great idea! ;)

Stay creative!

## Recommendations

• ### 3D CAM and CNC Class

565 Enrolled

• ### Casting Contest

We have a be nice policy.

## Questions

If you don't have access to LEDs or other components, you can use this augmented reality app to experiment with some simple electric circuits: http://arcircuits.com

Now you got me interested in making a more comlpex solderless circuit just for fun,

May be run a contest with a prize....

Just a little technical note :

The resistors you mention are far from ideal for this.

150R (brown/green/brown) will give you a LED current of around 52mA which is too high for standard LEDs. They tend to be 25mA max. Your LED will overheat and fail early with this.

The other resistor you mention (red/green/red) is 2.5K (2500 ohm) which will give you a current of 3mA which will be very dim.

A better value would be 510R (green/brown/brown) which would give you 15mA. 470R (yellow/violet/brown) or 560R (green/blue/brown) would be fine too.

Right, thanks for pointing this out :)

I'll change it asap as not to confuse others.

The reason it must have worked with me (and reviewing the packets) is because I wasn't using standard LED's but thanks heaps for bringing it up :D

I did change a few things, but they were things I wrote, not what you wrote. ;)

Aha...

I also put the original cover image as the last picture in step one, I think it works better. ;) I also wrote a note on it. XD

It is much better now! It was a bit hard for me to figure out what order to do them in, because some of the pictures looked similar. But I did it! (I guess) XD

Yes, well done!

How do you like the thumbnail?

You've gotta do them 600x500 pixels ;)

I think it looks cool! ;)
