Hello! I make electronics builds as a hobby and post the results on Reddit. Today, the account that has over 2 years of project post history and 22k karma got shadowbanned. I can't comment or post, and all my older posts and comments were removed.

I'm at a total loss as to what could have triggered the autofilter, all my posts were real and 100% humanmade. I mostly posted in DIY communities and shared fan projects for games I like. Nothing controversial whatsoever.

Here is an Imgur link so you can see my projects are 100% real.

I already submitted the appeal, but heard it can take months for the ban to be reversed. Can I make a new account to post the projects I'm currently working on and interact with others who build awesome things? Or would this be considered ban evasion and actually break the rules?

Finished the steampunk cyberdeck I posted a few weeks ago. Here is what I updated:

• Added keyboard labels
• Swapped out some plastic parts for metal ones, as suggested by others last time
• Added a dome over the ESP32 C3, the brain of the computer
• Wrote a CHIP-8 virtual machine for it and a little opcode editor, so it's possible to program this computer on the go while powering it off the engine
• Added some preloaded CHIP-8 ROMs
• Made a little manual for it that lists all the opcodes for programming and even includes some programs to type in

I also built a steampunk inspired work desk and ran around my hometown to try and grab some steampunk themed photos.

I found this cool Stirling engine online and immediately wanted to do a steampunk project with it. I decided to make a computer that actually works using power from the engine.

The electronics housings were designed and 3D printed by me. The body is made from old wood planks I found, finished with wood oil. The pipes are actually made from an old shower hose and painted gold, they're perfect for hiding the wires.

The engraving on the wood was made with my DIY laser engraver, which also looks very similar to this computer design wise.

I don't know if it fully qualifies as a cyberdeck, but I wanted to share a project I'm currently working on. It's an ESP32 C3 "cyberdeck" powered 100% by the Stirling engine mounted on top.

Since it's still a work in progress, the engine is currently just clamped on. Once I'm certain I don't need to take it apart anymore, I'll secure it firmly with screws. I also need to find small stickers for keycaps.

The end goal is to write a CHIP 8 interpreter for it. It should be perfect considering it has a 16 key keypad and a 128x64 OLED screen. Then it would be a fully functional computer you can even write programs for by typing the opcodes manually.

I'm working on a computer that is fully powered by the Stirling engine on top.

I made a Lumina Converter lamp that activates when you place a Nevron statue on its base.

Unexpectedly, some of my visitors saw the lamp and liked it so much that they asked if it would be possible for me to make one for them too, even though they don't know anything about Expedition 33. So I made more.

I released a new video that I worked really hard on and unexpectedly, it performed very badly across all metrics. I don't think I dropped in quality compared to my last video, which did really well. Even some of my very low effort videos have done 100x better than this one. What could be the reason?

I recently bought a toy stirling engine and got interested in how they work.
I found this video explaining it: https://www.youtube.com/watch?v=Q5QEBqjkNjo

But I have one question about what happens when the displacer piston pushes the hot air up to cool.

The video says that the air compresses and the power piston gets "sucked" down or that atmospheric pressure pushes the power piston down. But isn't the air inside the engine still more expanded than the outside air? Does the power piston really get sucked down, or is the air simply less expanded now, which allows the flywheel's momentum to push the piston back because the cooler air offers less resistance?

I've seen a lot of posts asking what others use their cyberdecks for, so I thought I'd share an example of when mine came in really useful a couple of days ago.

I had the stupid idea of writing a raymarching algorithm on an ESP32 and powering it with a stirling engine. The engine produces so little current that I can't power any external screens or transmit the image over wifi or bluetooth to see the final render. So I decided to use a small IR LED connected to the UART TX pin.

I then built a circuit powered by my cyberdeck that uses a photodiode to receive the signal, so I can actually see the image being rendered in real time.

I love messing around with electronics and for this kind of work the cyberdeck is ideal. It's much more portable and convenient than carrying around a laptop and I feel more comfortable bringing it into dusty conditions than I would a laptop.

Just a concept: an ESP32-based cyberdeck powered by either a small steam engine or a Stirling engine driving a generator.
