i wanted for a long time to have a control joystick(control box), wich can easy change the directions of 2 motors. so i made one. it's not hard to build and works perfect. the costs vary between 2 and 4 euro. feel free to change/improve the project using creativity and better parts. share your experience! i hope my bad english won't be an obstacle ( i have a lot of pics though :).
so have fun building the two motor control joystick!

Step 1: The Idea

on the schematic i use 1-pole pushbuttons (0.20euro/unit), but that's only because the 2-pole ones were too expensive (3euro/unit). so i had to group them to change the polarity. i also used a bit different schematic, but only because i didn't know, that these pushbuttons have 4 usable pins(you'll see what i mean on the 3th step). this schematic work too, but it can be a bit more complicated to build.
simple an effective i like it<br/>back in the day of commodores &quot;really old computers just in case your to young to know&quot; i would buy controllers for them they were similar to atari controllers<br/>and this is the part that may help you out a bit<br/>they actually used tire stems for the joy sticks ..bonus part is you can buy cool tire stem caps that look really cool<br/>check it out ...when you see it i bet it clicks in your head what im talking about<br/><br/><a rel="nofollow" href="http://www.sciencetoymaker.org/waterRocket/images/tireStem.JPG">http://www.sciencetoymaker.org/waterRocket/images/tireStem.JPG</a><br/>
hey, thanks for the idea, but it works perfect for me like this, because the short "stick" allows me to control it just with one finger.. ;)
this is constructive criticism,btw. item 7 is called a washer
hummm one could use a hollow tubing and insert a small POT with a wheel on top of the stick and run it in series with the push buttons<sub></sub> thus would make the output variable. the stick could be made from a short length of Automobile brake line. cut threads in to the OD and still use the nut and washer method to mate the push button switches. never the less this is a cool project and would be vary useful for manual testing on individual robotic system (s) parts of a single robot or other testing applications <br/> <br/>
Interesting.... I may have an application for that at the moment.<br/><br/>I would be interested to see you try this setup out on a future project...<br/><br/>The nature of the dial allows for almost instantanious switchs.<a rel="nofollow" href="https://www.instructables.com/community/Human-finger-model-movements-DC-activated/">My finger model</a><br/><br/>I'm going to try your idea out now... Thanks heaps!!<br/><br/>

<p>how have u placed the wires in the 3rd step? </p>
<p>exactly as it is shown in the picture in step one</p>
is there some way to make so that u can make both motors run at the same time, or some way to use it to control a tank with individual left right motors??
sure.<br>both motors are running(with half speed tho) in every diagonal direction(see video)<br>If by building you turn the whole schema 45 degree it will work perfect for your tank
thanks would an h-bridge also work link:<br><br>http://en.wikipedia.org/wiki/H-bridge
ask <strong>tomtom4388 </strong>
Hello! Could you tell me the title and artist of the music you used in the background? Good instructable thanks!

This is very, very cool. <br> <br>Opens up all kinds of possibilities.
this is actually an h-bridge<br /> <a href="http://en.wikipedia.org/wiki/H-bridge" rel="nofollow">http://en.wikipedia.org/wiki/H-bridge</a><br /> nice idea, but you have to be careful, if you press back and forward buttons at once you short-circuit your power source<br /> when using small batteries not too much trouble, but when using an big power supply you risk burning your switch or wires<br />
I've been looking around for something to control a mini prize claw. This would be perfect! Thanks for the great 'ible!<br />
By any chance, could <em>Part 7</em> be a washer?<br />
thats what I am thinking..<br />
You could use this to control a 3axis milling maching with regular motors instead of steepers. BTW what kind of motors are the ones you use. DC?<br />
Nice...if i wanted to do this with a higher battery voltage, say a small 12v battery, would i need to change anything, like the wire gauge or etc..
I'd say the easy way would be to just scale up, use switches and cables for 12 volt. The cool way would be to use relays closer to the motors.
could u upload a new schematic like the one u used
ah, ok, i got what you mean by "the one u used" . it's actually the same schematic. u just have to test which 2 pins make contact and leave the other two... that's all. you can see better what i mean in step 3, pic2. have fun! (and ask, if needed)
k thanks
i don't understand where is the problem in this one.. ok, it's not like the schematics you get from radioshack, but i think it's clear enough.. i can't make better one, but i can answer a specific question, when you have one ;)
this puts every idea i've had on this manner to shame. it's better than an h-bridge, and simpler than a microcontroller.
Your INSTRUCTABLE is really *NEAT* !!!!<br/>I love simple idea to solve otherwise a bit complicated problems. <br/>I have to say I NEVER THOUGHT about such circuitry before!<br/>I think, if not patented, it should!!!<br/>CONGRATULATIONS!!!<br/>
Not to take anything away from your project, but I like to plant this seed where it seems to fit. I'd like to see some electronic genius convert a $30 game controller into a real radio control device.
I will be soon, but seems a tad overdone on the net of late. Would be good to see one at Ible's though. ;)
That's a neat little project - It looks at first like its variable speed - but thats just the motors spinning up.
sorry, but the speed is constant :( <br/>i have a simple 4 motor <a rel="nofollow" href="http://letsmakerobots.com/node/740">robot arm</a> looking for a new controller, so i have to make one more. i plan to use variable speed there..<br/>
