Thanks! I’ll get one of each and see what works best :slight_smile:

what kind of speaker would you guys use for a lil sidrassi build? i’m building four of them and giving them as christmas gifts.

supposed to be 8ohm 1 to 3 watt.
I tried some like this that I ordered from tayda and they were far too quiet…
I’ve just been going to st. vinnies and other thrift stores/charity stores and getting toys with speakers in em for 10 to 50 cents and salvaging. lol.
Mostly bop-its and junk toy keyboards with broken keys and such.

+1 on buying thrift store toys and boom boxes for speakers, especially for a paper circuit.
In my experience, 4 ohm speakers are much louder and the TI LM386s are rated for 4-32 ohm speakers. More impedance = less power= quieter. This can be helpful in a circuit that doesn’t have a volume control (not that you couldn’t add one.) Check the datasheet.

i just tested the ohms of an unlabeled speaker i got from a cellphone auxiliary speaker. I have my multimeter set to 20 in the Ohm setting (this is the only setting I can get a response on the display. The speaker makes little crackling noises and the meter reads somewhere between 160 to 180, very inconsistently. Have I broken the speaker?

edit: i tested it again without the wires on the speaker and it sat between 8 to 12. i think its ok. now its at 4! hm

Should be fine. Resistance isn’t the same as impedance but it’s close enough for this.

How would I test for impedance on this multimeter?

I think you need an oscilloscope and/or signal generator but like I said, a meter measuring resistance gets you close to enough. If I remember correctly, a 4 ohm speaker usually shows as 3 ohms and an 8 around 6.

the layout and colors of this are fantastic. do you have a shot of the internals by chance, very interested to see how you made this.

Pot for each axis acts as a voltage divider.

Buttons are just momentary normally closed switches. The way I’m planning on wiring it will result in the same voltage being sent to the out of both buttons (that I can pass through to individual outs for each by holding the button down).

I’m not 100% sure but I have a feeling that Insta pages aren’t visible if you don’t have an account, so just in case (and anyway ‘for the record’) here’s what PB wrote:

ciat_lonbarde Guys. In a few days I will be closing my ordering page and preparing to move it all to Berlin… please don’t panic at this announcement though; you can expect to find my detail woodworking coming from somewhere in East Germany! Don’t know how long we will be gone yet but it may quite probably involve the school year.

Thanks to all my American customers. Bay area, Minnesota, PNW, east coast, the south, I love you all. We’ve always understood each other since the Bushyears, and my business owes a lot to you. I will try to have a brief popup store once a year in the portland lagerhaus, to satisfy your local walnut and shipping needs. We are off before the new year. Enjoy your new president!

I have been considering a stuber for a while but I’m not sure how much “normal” filtering I could get out of it if that was the goal. I get that it isn’t the point of the instrument though.

I have however been really considering selling my coco2 these last couple weeks maybe this is a sign.

Definitely a big change. I feel like the signs were there though. There were recent price increases, probably to bring their prices more in line with patch point. Overall, though, I’m sure this has more to do with personal (i.e. family) reasons, than professional/commercial reasons.

I wonder if korg took him up on the proposal he sent them (http://petermopar.blogspot.com/2020/06/proposal-for-korg.html).

This would be pretty cool.

“been considering stuber for a while”

Your enthusiasm for the stuber in ciat groups far and wide is half the reason why there was so much excitement when it came out in the first place!

Understatement of the thread!
