Do you know the game called Buzzwire where the aim is to guide the grip mounted loop through the wire maze without touching the loop against the metal maze all the way to the end? is it possible to get the position of the "wand" along the metal maze at any given moment and also detect where a "touch" event happen?

Specific question: what method/system/strategy should I use to get the x coordinate position of the wand (see picture) along the wire at any given moment into an arduino device or similar?

The idea is to use the device as "game controller" and move a character on a screen based on how fast the player is moving the wand along the wire

    \$\begingroup\$ Welcome to EE.SE! Keep in mind that "Is it possible ...?" is a yes/no question. In this case, the answer is "Yes". If you're asking us to design it for you, that would be too broad. You would need to specify something about the level of performance you expect as well as what constraints you have on the implementation. What is your specific question? \$\endgroup\$ – Dave Tweed Sep 20 '19 at 15:29

    \$\begingroup\$ I drew this but the question was closed before I could post. i.stack.imgur.com/W9qTm.png. (a) A constant current source. (b) Using a lamp as a constant current source.* If you have access to a lab power supply with a 1 or 3 A capability try figure 1a. If not try 1b. You'll need a sensitive voltmeter. \$\endgroup\$ – Transistor Sep 20 '19 at 15:38

    \$\begingroup\$ like @Hearth wrote it should be possible but a lot of work. If you just want the position at time of contact you can use a non-oxidising resistive wire (stainless steel) with a decent current flowing through it. To measure without contact you may have to use some sensitive time domain reflectometry or perhaps capacitively coupled stepped frequency standing wave detection that will detect which modes it is near at many frequencies that are transmitted into the transmission line. \$\endgroup\$ – KalleMP Sep 20 '19 at 16:20

    \$\begingroup\$ thanks @KalleMP , still not sure why this question was put on hold after just few seconds of being published and now that I edited it and clearly people is understanding it, it is still on hold after an hour \$\endgroup\$ – Delcasda Sep 20 '19 at 17:07
