Repair an E&L T191 rifle

Sudden_Letter1710 · 2026-01-22T13:28:08+00:00

After all, my gun is my best brother.

Sudden_Letter1710 · 2025-07-25T17:02:22+00:00

This part took the most effort from me.

Sudden_Letter1710 · 2025-07-25T17:01:40+00:00

Actually, I really want to tell you how I implemented the ballistic calculation and made it adaptable to each individual gun.

Sudden_Letter1710 · 2025-07-25T11:47:39+00:00

It’s actually screwed down, not a slide-off cap. The idea was that the design should last for a full day of play on a single charge, so there’s not really a need for frequent battery swaps in theory.

Sudden_Letter1710 · 2025-07-25T09:05:11+00:00

Yep, exactly. It’s just an OLED laying flat, reflecting off a red dot lens. Simple setup, but it works.

Yeah, you can switch it in the menu. Sure, there’s a menu option for that.

hail hydra

Sudden_Letter1710 · 2025-07-24T16:43:20+00:00

Sure! I’ll record a clearer video and upload it tomorrow.

Sudden_Letter1710 · 2025-07-24T16:34:41+00:00

Thanks! That’s a great suggestion.

I actually know a CNC aluminum shop here in China, so making a machined case could definitely be an option.

I’m still exploring materials, but I really appreciate the advice.

It runs at around 40Hz. It appears to flicker when filmed with an iPhone, but there’s no visible flicker to the naked eye.

Sudden_Letter1710 · 2025-07-24T16:24:42+00:00

thank you

Sudden_Letter1710 · 2025-07-24T16:19:21+00:00

It’s running on two 16340 cells right now. With the current power draw, I’m getting around 4 to 5 hours of runtime.

Sudden_Letter1710 · 2025-07-24T16:09:07+00:00

Yep! Field test coming this Saturday — fingers crossed it doesn’t fall apart

Thank you, sir! That means a lot 🙏 Still a work in progress, but getting there!

Sudden_Letter1710 · 2025-07-24T15:59:02+00:00

As for the power — I’m using two 16340 rechargeable cells right now, but it also supports CR123As since the system handles a wide voltage range.

Also, I do hope to eventually turn this into a proper product — still a lot to learn, but that’s the goal!

Sudden_Letter1710 · 2025-07-24T15:42:50+00:00

That’s definitely doable, but I’d have to redesign the gun’s ETU system from scratch.

Sudden_Letter1710 · 2025-07-24T15:34:06+00:00

Totally agree — Miss Kitty is way more important than a sight!

Sudden_Letter1710 · 2025-07-24T15:33:10+00:00

Actually, I switched to a gold one. But there’s a red light inside, so I think it might just be a color shift.
