Use leap motion on raspberry

I think it's good.It seems like what I do.

Use a old laptop to link LM?

LeonYuhanov 2014-05-15 02:50:37 UTC #23

Like this.
1.write a nodejs app that has an http server, have the server poll the lm for data
2.write some code on the raspi to POLL data from the nodejs app on the laptop

It is really quite short-sighted of Leap to be failing to support as many platforms as possible. The hardware is useless if you can't use it beyond the lifetime of the x86 hegemony.

Linux runs on more than just x86, folks. Its just a build or two away to support as many platforms as possible. If you don't want to pay for the work, let us .. in the community, from which your Linux compatibility is derived, fix the problem. Either open source, or establish a trusted chain to port from, and let the release engineers off their chains so they can focus on forward-features for your Product.

BTW, its not too far-fetched to emulate x86 on ARM. Sooner or later, it won't matter .. but it sure would be nice if the so-called 'progressive device makers' embraced the spirit of the platforms for which they claim support.. open-sourcing the driver for Leap might make a huge difference about whether people actually use the things, and keep your plaftorm alive.

For what is worth, if the sources were available I'm sure we'd be using Leaps with pretty much everything we possibly could. Its just that I want to give up x86, personally.. and closed-ness as well.

We're working on providing full ARM support. It's currently in private beta.

Raspberry Pi is slower than our minimum spec CPU right now by a factor of 20x. It is unlikely we can support full skeletal hand tracking on this platform.

Maybe we'll come up with something else creative in the future though.

I had checked the same setup as you, Raspberry Pi B+ with VirtualHere: Fine detection of USB device but simply no hand detection.
However, that setup works with Banana Pi! Its faster Ethernet controller enables for the necessary high-speed image transfer to the Windows7 PC.

Hi,
please see my post about the new ARMv7 Quad Core based 1Gb Pi 2.0 here: https://community.leapmotion.com/t/driver-for-embedded-arm-platforms-like-raspberry-pi/886

@LeonYuhanov I need ur advice.

I have a node/socket.io server running fine in my RPi 2 already. Now I'm connecting LM with a laptop and I need that app.js in my Pi to be able to listen to the data from LM via websocket port 6427 (LM's default) from that laptop with another ip address.

Can you guide me through?

LeonYuhanov 2015-04-29 01:45:11 UTC #29

Hey mate
what you want to do is

Set up a nodejs app on your laptop to grab lm data and "serve" it on POST/GET requests
Have the RPi run an HTTP client that POLLS the laptops node server for lm data

Thanks so much. Just wondering. Can I omit the "node" part on the laptop since the LM is already running a WebSocket server? Is there a way I can just use the Node/socket.io server on the RPi to poll on that address, say 192.x.xx.xxx:6427?

LeonYuhanov 2015-04-29 02:15:24 UTC #31

Absolutely, if you can get your Rpi to connect as a WS client to the laptop you are good to go!

jochasinga 2015-04-29 02:28:09 UTC #32

Oh my I've never thought of that. You've been a huge help!

tgraupmann 2015-05-02 22:12:47 UTC #33

I used a C# HTTP server running on a PC to proxy the Leap Motion controller data to Raspberry PI which moves servos using the Leap data.

r u sure the banana pi will work??

mattgreenlake 2016-04-29 20:09:03 UTC #35

how do we un-private that beta? seriously. let's push this. linux on arm is a huge miss for the most obvious of reasons. IoT is prototyping like mad in the wild with cheap devices. You must run on them. More efficient code. Go.

user-339616738 2020-07-09 12:10:59 UTC #36

Is a Pi4 fast enough?

Carlocattano 2021-10-14 08:59:52 UTC #37

lets find out . Pi 4 with 8gb ram should do right ?

dankirby 2021-10-14 10:47:57 UTC #38

Currently our hand tracking SDK is not compatible with ARM devices and unfortunately the Raspberry Pi 4 is ARM-based.

For now I would recommend investigating a small Intel NUC machine or a tiny x86 based computer which are RPI-like but not ARM which may work better for you.

Intel NUC mini-PCs are below the i3 spec but we've heard multiple reports that the hand tracking runs fine on them. However we are not sure what models people have used and it is worth noting that they have i5 processors that go as low as 1.3GHz up to 2.6GHz turbo dual core.
