"Tryone" Gooseneck tablet holder to hold my Linux-running x86 2-in-1 tablet. I get like 2 people a week asking me what the fuck this is and how they can get one ASAP. Unbeatable ergonomics at any place; your screen where you want it. Paired with a Lenovo Thinkpad Trackpoint BT keyboard, and sometimes a mouse.

Gas-spring monitor mounts are well known by now. I semi-recently hacked together a wall mount gas spring arm & am surprised how much more flexibility & space going from desk mount (first clamp then through-hole) arm to wall-mount gave me; better range of motion, zero desk-space is amazing.

I used to dearly love my Griffin PowerMate jog-wheel for volume control. I really wanted to create a morse-code system for it & got quite far but stopped 50% of the way through. But still, jog-wheels are lovely devices. I'm on split keyboards now but I love so much the old Logitech MX keyboards that I had that also had big job-wheels & media-buttons; having on-tap control over devices was so nice.

AtomCube RX1 (now RX7) has a pretty nice battery-powered videography light that also works great as my key light. I hope one day to figure out how to reverse engineer the bluetooth control protocol for it, but haven't started digging in to how to intercept/reverse engineer the Android app. I also really dig the very cheap the Aputure AL-M9 deck-of-card sized light that works great with my camera; just so versatile a light & imminently affordable.

Fiber optic displayport/hdmi cable. I used to use a 50ft 1080p hdmi cable & some active USB extension cables to put my computer in the hallway or bathroom, connected to a separate terminal, so I could have a no-noise environment. Now, my AIO coolermaster watercooled computer is quite quiet. But there are some very cheap fiber optic cables of up-to literally hundreds-of-feet of length for incredibly cheap prices. The no-name brands seem to work fine. Now I can play games on my roof just fine, thanks to these absurd cheap luxury devices. I've tested up to my gaming monitor's 1440p170 and they work great.

A $20 HDMI<->USB "MS2130" converter for plugging in my cameras as webcams. Present as standard usb-video devices. Alas the frelling monsters making Android phones still don't include the kernel module to support these; how very badly I want to be able to use my phone to control & connect to my cameras, but nooo. Tick the kernel module box on for usb-video, you jerks!

ElecJet Ultra is the most interesting battery pack I have. It's only 10k mAh- <40WHr- which is low capacity. But it charges at 100W across a huge part of the charging curve. This makes it an idea travel unit: wherever I am, I can accept wall power at 100W. That's 3x the rate my laptop accepts. I have some ZMI 20k (mAh) Pro packs that I adore as my mainstay everyday travel units, lots of juice, very compact, nice usb-hub features, but they only charge at 45W, or a ~2hr+ charge time. Being able to get a fully charged pack in ~30 minutes is incredibly useful if I'm on the go & trying to keep a couple devices charged. That said, I often have two ZMI Pro packs, and my multi-output charger will do 90W into both packs, and thus the ElecJet often stays at home. It's still a rare noteable gem of a device to me.
