My interest is piqued. Are there file size limitations with scripts? I have a handful of scripts I can’t use with my Handy because the file sizes are too large.
Very thorough and informative review. Great side-by-side videos.
Your autism (non-derogatory) is much appreciated!

Great review, informative and straight to point. Looks very promising, I’m definitely interested. Nice design, honestly the look of the OSR group of toys is a huge turnoff for me, so that’s a plus here.

Great and interesting reviews Falafel! 
Questions
Which machine is the fastest one between the SR6 and the FunSR1?
Regarding the SR6, you wrote that “actions below 600 units/s are safe to use”
And do you think that the AI-H200-1 with increased load capacity correlates with a boost in speed?
Another point I’m unclear on is the engine powering the FunSR1 brushless, or does it not matter because it is another type of engine compared to the ones in sr6?
Does it seem like the FunSR1 might be even quieter than the Handy, or am I mistaken?

OSR2/SR6/SSR1 creator here.
This is a really cool review and interesting reading. I’m very pleased with the SSR1 mechanism and it’s exciting to see it put through its paces in the FunSR1.
The creators of this device were kind enough to contact me before releasing it, I am aware of it and I have absolutely no issues or objections to what they’re doing. 
Of course, for those of you who are interested in having the fun experience of assembling this mechanism for yourself, and having the confidence to maintain and repair it if necessary, I will shamelessly plug my Patreon page. I’ve learned a lot from SSR1 Alpha and I plan to release the updated Beta design later this year, as well as some other extras and upgrades

Thank you for your affirmation of FunSR1. The main differences between FunSR1 and SSR1 lie in the mechanical structure, with the tensioning structure adjusting belt tension and the slide table structure reducing friction.
Your innovative T-CODE protocol serves as the foundation for the majority of interactive toys today. Designs like SR6, OSR2, and SSR1 have all been very popular.

FunSR1 is a gimbal motor, while FunSR6 is a servo motor, so FunSR1 is quieter than SR6. Additionally, we’ve optimized the structure for noise, so FunSR1 might be quieter than Handy.

Great review. The videos are fantastic demonstrations of the advantages of Tempest’s devices. And the linear rails are dope AF.

Both seems capable at playing actions at 600 unit/s without compromising length, which is where I stopped demanding (rarely do I need to go beyond 600u/s). I’d say the FunSR1 (SSR1) is more stable at faster speed than the SR6, running the same script the gimbal brushless motor also gets less hot than the servos of the SR6.
Volume wise they sounded similar to my ears. Here’s the waveform for comparison.
The Handy has abrupt change in velocity which causes peaks when it moves. It is also higher in pitch.
I’ve not tried these. The FunSR1 (SSR1) uses gimbal brushless motor instead of servos.
No. The Handy needs to download and cache the script before playback, hence the size limit. The SSR1 doesn’t do this - player software such as MFP sample the script on your computer and send command in real-time. The size of the script therefore doesn’t matter at all.

neat. does it come with vesa adapter?
Is the rail louder than alpha 4 rods?
It’s actually quieter. Since you’re in Tempet’s discord, this might help:
Thank you for your review. I just found out that this device is made in China. It would be very convenient for me to purchase it.

Which motor controller board is that? It looks like a custom design?
If I understand this correctly they’ve combined it with the ESP32?

before I dig deeper, did anyone already figure out a way to integrate this with GitHub - stashapp/stash: An organizer for your porn, written in Go. Documentation: https://docs.stashapp.cc ?
Someone have had success here. Basically you play videos using MPV and MultiFunPlayer handles the script.
If it works with OSR2/SR6 it works with the SSR1.

many thanks! I will check that out.
The ESP32 cannot drive a motor directly, it needs to be combined with a driver IC or an array of FET’s. My google-fu cannot find an esp32 board with a motor driver this small, so I’m thinking it must be a custom design.
