I don’t necessarily mean adult as in NSFW.

I’d probably bring in my RG280V. It was my first handheld emulator. I had emulated games on my phone in the past and even used a Bluetooth controller but playing on it felt different. More real in a way.

I grew up with the Game Boy so the idea of having thousands of games on the go is pretty neat to me.

I’ve since moved on to the RG405M.

What about you? Do you have anything neat or special to you that you could talk about for a couple minutes?

Would love to see photos as well

    I’m an antenna engineer. I’d bring an antenna because after hearing a lot of adult show-and-tells I figure people could probably use some sleep.

      99% of audience dozing off, 1% fascinated by the mystical art of antennas and radio waves. I know the science behind it, but I still don’t know how you guys came up with some of those designs.

        To be honest, we learn about the basic antenna designs, and there are many, and then usually new designs come from altering some idea to fit a new need, until there is nothing of the original idea left. LOL. Usually, we’re asked to size reduce but it’s just not physically possible to do what is often asked of us. There is a running joke in the industry that customers always want an infinitely small antenna with infinite gain. Usually we start with something like a monopole design and change the physical parameters until we can no longer meet the spec. Hopefully the antennas fitsb in the required space. At least that how did it. Necessity is the parent of invention, after all.

        Never used that myself. There are many programs we use depending on what property you are looking to calculate. I’d say the main tool is HFSS. I personally used CST mostly because when I was learning all of the licenses were usually in use and CST was always available since it was not as well known. But seriously, I’d estimate there are literally dozens of programs plus programs that each of us writes, usually in Matlab.

          Matlab

          That might be the barrier. I seem to remember NEC2 was the only game in town for amateur use, which is why I have it installed. It’s the only thing I’ve used that still expects punch cards.

    Not sure what a show and tell is, I guess my laptop with tons of stickers, and boot up something that looks hackery. Besides that, my guitar perhaps?

    I would bring my modular synthesizers. I brought my eurorack set up to a synth meet up and it was the most popular station next to the theremin

        Thanks! Fraid not, it came together pretty ad hoc as I was building it.

        Essentially the process was breadboarding the major components to get them talking and sort out the software, then built the main board to hold everything in position, then built the box to fit around it all

      Better charge that thing!

      Is this universal remote in terms of IR to your TV, or more like connecting to Plex/Kodi/etc?

        Yeah the battery management board is a bit flaky so keeping it charged is a pain! Yeah it’s just doing IR for the various living room devices, sound system, TV etc so I didn’t have to keep tabs on 4 different remotes

          Ah that’s really cool!

          Is it nice to use? For a bit I used a Kodi app on my phone but it gets annoying having to unlock your phone, open the app, then hit pause or whatever you’re wanting to do. I presume this is much nicer.

            Its great to hold! Very chunky in the hand. Functionality wise I only gave it the on/off, volume and input selection from the media devices, and then it talks to another esp32 base unit that controls some lighting over WiFi, but as far as actually driving the media controls I shamefully just use the Google Chromecast controls, I’m not savvy enough to set up a FOSS alternative yet

      I LOVE this. I’m pretty sure I’ve tried every single media/pc remote available, and they all suck for one reason or another. Been thinking about building my own, and this is totally the direction I would go. Thanks for the inspiration!!

    Probably my chi-fi headset. Don’t really have anything to show off. And maybe my laptop to show that I use a package manager of the future.

    Probably my wheelchair. It’s a pretty nifty little chair that has quite a few unique features. Also I would need it to get there anyway. Otherwise maybe one of my drawings.
