Unfortunately no, at least not that I can still find. It was really just a lap tray and I used industrial Velcro with adhesive on the back, along with an adhesive mousepad. The mouse holder is just from the box it came in.

The challenge was the lack of wireless for the single-handed hardware keyboard at the time, so a USB2BT module was needed, and those knobs I added at the top were for wrapping a wire from a tiny USB2.0 Hub for if I wanted to be wired.

Doing it again it would be 100% wireless with magnetic quick charge connectors on all the elements. (I got a million of them of different angles off Aliexpress and have them on all my travel items).

Admittedly I did this years ago, and had to use USB to BT adapters which was janky. Wireless keyboards are much better now 😉

Ahhh yea. If I were to do this with a backpack I’d probably make something folding. Having the tray is super nice for couch visits.

Hear me out, you don’t want portable, you want transportable. I made this. It’s a lap tray with cushion underneath and a handle, and everything attaches to it.

I might look at this, but part of this for me was the engineering experience of building the connector along with supportless parts. So I’m not sure how much time I’d put into adapting away from that. Thanks for the suggestion!

This is correct. There are alignment holes and tabs for everything, so it’s pretty painless. It was a requirement to have zero supports, which is more work than a dot of glue IMO, so I went that route.

Yea, it can be used with lots of things, just starting here 😉

I actually use the paddles on the deck, so it’s nice to have them on desktop and when docked. It’s not cheap, so it tooke a long time to pull the trigger on, but glad I did.
