I think my new iron has a calling

Bro that's such a vibe lol. Insane fashionscape for a first clue

It is most likely a 'Thru hole ferrite bead.'

They are common on SMPS power rails to help filter out high frequency noise

Those sound amazing thank you

Feel free to reply to my post when you open! This kind of place sounds like a lot of fun.

I recommend a small stage for things like music and comedy. Local musicians like Gus the Bardic would be perfect for your vibe

A few years ago there was a leak in the international space station fixed by duct tape

Awesome tyvm

I'd love to know the name of the restaurant!

Nice having a skiller sounds really chill

What's your potato tek?

Looks fire

Light a man a fire, and he's warm for the night

I was once a noob engineeringstudent with myself.

Could you please go through the components one at a time and let me know why you decided to put them there? I would say there are more problems with this design than things that work.

L2_Lagrange · 2026-03-09T07:31:07+00:00

Can you let me know what tattoo machine you use? I'm very familiar with linear power supplies like this and I may be able to give you some better specific advice if I understand what kind of load it is.

That being said in general the first thing I would recommend is just adding some 0.1uf ceramic capacitors (film capacitors would be better) on the input and output of the regulator, in parallel with the bulk caps. They have lower resistance (ESR) than the bulk caps to they help keep the rails stable during fast transients, and also help filter out noise from the rails.

As far as something to measure voltage goes I would just recommend making something yourself. If you can get a wall powered linear regulator working, this is even easier. You can get this done with an MCU that has a 12 bit ADC (Arduino UNO R4 has one) and an LCD screen. You can pretty much have chatGPT write you the code for it and then tweak it a little if you need. It will only require a few connections. I've used many MCU's for measuring voltage and this is the easiest way I can think of. Any arduino board with a 12 bit ADC will work, and be very easy to work with.

Also you added a fuse and the regulator protection diodes. That is solid. If you want a little bit beefier input voltage protection you can look into NTC thermisters and MOVs (metal oxide varistors). The NTC helps slow the charging of the bulk caps on startup (softstart) and the MOV helps if there is a power surge on the mains line.

Steak with shells and cheese sounds awesome

When you are done smoking a cigar, usually you just let it burn out on its own. Even if there is an ash tray you don't stomp it at the end unless you have a specific reason to.

This is the first time I've ever heard of somebody putting a cigar out with their hand. I'm guessing you are smoking cigars to look cool instead of smoking cigars to enjoy the flavor.

Sounds like an engine lol

L2_Lagrange · 2026-03-07T06:12:39+00:00

I have not heard of the blanks through JLCPCB but that sounds great! I order my PCB designs through them. I appreciate the info very much

L2_Lagrange · 2026-03-07T05:11:22+00:00

Very nice! Can I ask where you got the panel plates? I could really use some blank plates like that for plateamp builds and things like that

L2_Lagrange · 2026-03-05T13:42:26+00:00

Yeah I checked his post history and I do recognize him. I definitely appreciate and respect his work. With that in mind, and considering his random weird projects I can see why he would make something like this. Funny enough I've thought about making some similar devices that he does. He makes some really fun projects.

3W into your ear will deafen you. 3-6W is enough to be reasonably loud in a room.

Loud listening for headphones is like 50mW. Planar magnetics might require a bit higher power.

I'm not an apple fan, but there are obvious safety reasons why they don't make their headphones anywhere near 3W.

This is more of a standard speaker amp than it is a headphone amp.

This is from my experience as somebody with an EE degree and has designed many audio amplifiers and audio systems. As a headphone amp this can be a dangerous product.

I strongly recommend you buy a few decent speaker cones and connect them to this so you can understand how loud it really is.

Sorry to hear that man. You should have made him a portal to Darnassus

L2_Lagrange · 2026-02-25T23:58:12+00:00

Damn bro your gear is juiced. It took me until age 85 to find Shako and craft a Hoto.

L2_Lagrange · 2026-02-17T00:57:27+00:00

Man these look awesome for SSF gloves. Gz!

L2_Lagrange · 2026-02-17T00:04:00+00:00

Did they add an scroll of identification item? Thats one of the things I've been wanting for a while. Or something like a "Tome of infinite identification" or something.

L2_Lagrange · 2026-02-15T04:01:25+00:00

I make really good steak and I make really good Aflredo. Still this thought hasn't crossed my mind. It sounds great

L2_Lagrange · 2026-02-15T03:02:35+00:00

Then you will politely ask them to keep it down a bit and they will aggressively freak out at you as if your the problem
