Tools and parts to build a Spout
Make Spout a low cost beetle bot that can avoid obstacles. Spout is low cost and can be made without solder. Created by Karl Wendt.

What is the cost of materials for this project? How much, generally, do the tools run?(8 votes)
Approximate cost: $10
The tools will probably run for 5 minutes at most total, if not less.

Hey I have a question for you . I live in Bangalore in India and I want to know where I could get the above mentioned parts .(3 votes)
Even i live in Bangalore.. You can try Om Electronics on S.P road.. I always buy my project materials here. Here's the address--
No.110, Near To Town Hall, S P Road, Bangalore - 560002

How long will the end product be able to run on one set of batteries?(3 votes)- Do they sell these parts in stores like Home Depot?(1 vote)
RadioShack will have everything you need. Digikey.com and Mouser.com also have the parts.(2 votes)
- what resistor fits 2 5mm led(1 vote)
- can you use any colerd wire for spout or dose it have to be spfiic(1 vote)
Actually, You could use any color/colors you like for this project, all the different colors do is help you remember what everything is. For example: black goes to ground or the negative charge, and red goes to a power or the positive charge.(1 vote)
I have to make a project for physics Topic is SCIENCE AND SOCIETY. Can you suggest something?(1 vote)
You could build Spout! You could say that it is for carrying cokes to people. :D(1 vote)
You said in an earlier video that the two batteries make up 3 volts together. The motors together require 3 volts, so are the motors losing power to the LEDs?(1 vote)- Blue and green LEDs use more power, right? If so, I have two questions. Why do they use more power, and also, can you use blue/green LEDs with this bot, or do they have to be red?(1 vote)
Video transcript
So this is the first of a series of videos in which we show you how to build a ‘beetle bot’ without using any solder. This is our Khan Academy ‘Spout’ beetle bot. So it's got LED eyes, and a bunch of different ways you can make it. So the first thing we're going to do is to organize all of our parts. And we’re go through each of the different components. In this kit, we've got 2 bottle caps, 2 sliding switches, 2 single-pole-double-throw lever switches – We also have 2 1.5 volt motors, 4 large paper clips, and 2 AA batteries. You’ll need a AA battery holder, as well. And some hot glue, 2 LEDs, and 2 resistors. You’ll want to make sure you pick resistors that fit with those LEDs. I believe those are under 60 ohm. And then we have 5 multicolored wires. Okay. So now we’re going to talk about the tools that you need to make this project work. You're going to need ... a hot glue gun. (And any standard one will do.) And needle-nosed pliers to crimp the wires together. And you’ll need something to strip the wires with. You can either use a wire stripper or scissors, if you like. Alright. So let's get building.
