## Description

Solder The Useless Machine control board, then go on to solder the counter circuit. When you've finished construction, you've got a Useless Machine, that can count exactly how many times it's been Useless!The Useless Machine is a gizmo that turns itself off when you switch it on. But how? Is there a little stubborn person in the box playing a trick on you? Is it magic? No, it's a set of switches with a small motor and you get to put together! By building the kit yourself only you will know the secret of how it works. When you show it to your friends and co-workers, keep them guessing - after all you built it, it's your secret!

Review: Clear and concise instructions. - Easy to solder, instructions were clear except the motor shown isn't he motor in the package so I except it to confuse some people as to the orientation of the device but it's nothing hard to fix if you do get confused. My only real complaint is you have to thread rubber tubes yourself before installation which is very taxing on your hands but it does make final installation easier as it promises but my hand got tired after the second one so I put a glove on to help the strain. Putting the black box together is a pain but it's nothing abnormally hard. The solder is very easy for the box itself but the LCD screen I would pay extra attention to the instructions. I really appreciate the troubleshooting part of the instructions because it has the solution to the most common issue you'll have which will be the arm going the wrong way. I also love you didn't need to solder the power supply to the board, only the connector, very user friendly for people who make wiring mistakes. Heavily recommend to people learning to solder. Nothing is difficult in it.

### ⭐ Parts broken
*by S***N on September 15, 2024*

Motor was broken, not much else to say

### ⭐⭐⭐ Fun to build but not strong enough to turn off
*by C***X on December 25, 2018*

My 12 year old had a lot of fun soldering and building it. The problem: the "hand" isn't strong enough to turn off the switch. It has been rendered completely useless.
