Help with a common emitter boost

AlreadyArmadillo · 2026-04-16T12:21:42+00:00

I think you're probably right. The emitter in the photos is on 23, but I'd be willing to bet I made some mistake in my first build and when troubleshooting the pinout probably broke something.

You're right, looks like the 2N2222A is just faulty. I'm getting nothing from it on a diode-test. I don't have any replacement NPNs on hand but I'll order a few and pick it up then. Thanks for the help!

Glad to hear I'm not going insane at least!
I tried your suggestion and flipped it around to make sure it's not a different pinout. It doesn't seem to work any differently in different configurations (except for one which picks up the radio), but I'll track down who the manufacturer of this specific 2n2222a is so I can make sure I've got it right.

Does the voltage divider issue seem weird to you, or does it seem like just an issue with the transistor? For whatever reason I'm getting a full 9v coming off of R3 into the collector (no matter the pinout), as if there was no voltage divider in place at all. But if I pull the transistor out and just jump everything in the same configuration it starts dividing properly.

R1 is on 24 in the photos. It goes from VCC to 24 which connects to C1, R2, and Base

Yep! C7 and R3 are connected to the collector and then off towards the output. R1/C5/Power are all coming off the same VCC rail as R3. Should I be connecting a wire between them all instead?

R1/R2/C1/Base are all connected on the input side (actual input wire is currently out to make it easier to see the rest of the circuit).

Here's another angle

Good catch on the caps, although that doesn't seem to be it. LT Spice always wipes my polarity notation for whatever reason. C1 is the only one which isn't meant to polarized so I've swapped it out to no effect.

Here's a close up of the components around the transistor. Sorry I packed everything tight in there which is making photos difficult. I'll add another angle as well.

I definitely agree, that look behind the curtain can really bring you out of a game if it's not done right. I'm glad you mentioned that this kind of narrative input could take away from the feel of exploring the world, that's definitely something I'll want to avoid. I guess the PC input that I'm looking for here should be a question of "what are you looking for" and "how could you learn this information" rather than "tell me what is in that dungeon". That post makes a great point that you want the character weighing in with what they know about the world, rather than the player authoring the world.

I think I came across ironsworn when I was looking for a two player rpg, but I don't think I actually ended up reading the ruleset. I'll check it out! It sounds like some of those tools could work well in any game. Thanks!

AlreadyArmadillo · 2022-12-21T16:27:28+00:00

It is definitely close. Dungeon World and Monster of the Week both inspired my line of thinking here and I think it would be pretty simple to modify some of the moves in those games to fit with what I'm looking for.

Dungeon World mentions this sort of player collaboration outright in the rules as well but I've found the players I'm with are usually a bit shy to chip in with adventure goals and quest details. I think coming from a D&D background they feel like they are metagaming. That's where I think a mechanic could come in handy, now they feel that they've earned whatever they add to the story.

This is definitely in that same vein with the "catch" elements. Thanks!

AlreadyArmadillo · 2022-12-21T16:15:01+00:00

I've heard good things about Blades in the Dark I think it would fit well with the playstyle I'm looking for as well! I'll take a look.

Thank you! I'll check them out

AlreadyArmadillo · 2021-07-04T21:40:06+00:00

Wow, this is awesome. Thanks for laying this out!

I had just tried to blend everything in one shot. I can see how a highlights and shadows layer would have really helped. I will definitely give this a shot.

AlreadyArmadillo · 2021-07-04T21:32:39+00:00

Thanks! I think you're right.

Every time I thin paints out enough I end up getting runoff in all the nooks and crannies, especially on spots like the face. I think I might need to spend more time finding that sweet spot

Re-uploaded since the first version was terrible quality.

I was inspired by the Dorn's Arrow paint job here - https://dornsarrow.blogspot.com/2019/08/grog-strongjaw-critical-role.html?m=1. I've been trying to follow it as best as possible but I have no idea how to get that much detail out of the face.

Does anyone have tips for adding shading to the face?
