I used a 100k Ohm resistor in series with a blue led yesterday, and it still is a bit too bright.

Blue and clear were very bright, red bright, but amber and green were disappointing. I really like blue LEDs, but quite fancy trying some of those Cherry, Baby Pink and Magenta TruOpto ones that Rapid are selling.

Now that’s one extra fancy store brand if I’ve seen one. I wonder what the manufacturer calls these LED colours 
(They’re selling the classic $2-3 ebay/aliexpress LED tester as an official “TruOpto LED Tester” for a bit more than that, but ok, you get it a lot quicker and they have made a datasheet for it.)
EDIT: Oh, in the suggestions to the right, they offer clones of the Sunhayato IC straighteners under the label “TruSemi”, even using the same product code as the original. I wonder what other “I got this from aliexpress” brands they have? 
Got a new case going and finished several modules. @CTorp how many of those 25mm modules are okay to power from a single 2amp power supply?

I have no idea, probably a lot tho?
Pretty sure you could put whatever you want in that case with 2a

I bought one of these , of course I got the pcb kit thinking I would put it in a Kosmo panel and haven’t gotten around to it yet .

That’s rad! I want to build a small test skiff at some point this would be perfect
I have this usb power supply for it already

yeah some of us around here can design and build something like this ! but for the rest of us …

do we now if that’s ~.5A per rail or overall…
WE really need to get that data on power usage…

Hello,
I rebuilt your 6CH Trigger Sequencer w/SSD1306 0.96 inch OLED made for ¥800.
The display works. but I can turn the encoder all I want, but I don’t see any reaction on the display.
Inserted some Seriel.print into the software to see if the pushbutton and encoder give values.
They do.
But nothing happens in the display.
It always stays in manual mode.
What am I doing wrong?
Greetings tangram

Hey
all back. I had a cold solder joint. Sorry.
Now it all works.
Thank you

If I’m not mistaken the main code includes a header file for the encoder. I could not find that in the original publication by @HAGIWO. Where did you find it?
I found it at:
Works fine.
I found something else, namely the declaration of the clock input is missing:
void setup ()
display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
pinMode(12, INPUT_PULLUP); //BUTTON
pinMode(13, INPUT); // Clock !!!
This is how it works for me now.
Good luck

Great design ! How schematic have you used for it please ?
My two last quickly and dirty’s builds :
- A vactrol VCF inspired by @moritzklein (I think he have posted a post about it in the forum, also you can support him on his patreon page for acced more schematics !)
*A 808 BD clone with some mods by juanito moore:
Schematic here:
I am so sad and frustrated to I don’t have more time to hang around in my wiring since I got back to work… I absoluty must to finish my psu and bus boards… Long live capitalism…
