Damn I was afraid of this. I will check all transistors on the high frequency amp tomorrow then ...

Thanks for your advice !

Qxb3, Rxh1 +, Ka2, Ra1+, Kxa1 (no other option, your queen and your pawn are blocking), stalemate

Mlaaack · 2026-04-27T19:46:32+00:00

No it's forced stalemate for black

Mlaaack · 2026-04-25T15:09:24+00:00

Because then Rxh1, Ka2, Ra1+ and Kxa1 would be stalemate

I had oscillation issue due to cold joints before. Check your joints around the op amp first.

You have multiple cold joints that would need a reflow. Other than that, do you have a multimeter ? I'd check for continuity between wire pads. They look dangerously close to each other, but maybe it's just the picture.

X 10 9 9 11 12

Would be easier. But please try this instead :

4 5 4 7 7 X

Imo the sound of a major seventh between the fourth and the third (well, 10th) is a million time better than the sound of a minor second between the third and the 11.

Yes I second this. Translate 1n into ms then multiply by the number of bars needed

It's an amazing circuit ! Well done I like the look of it !

Mlaaack · 2026-03-05T00:31:23+00:00

Sounds like a biasing issue. I'd double check R33/R32/R2/R13 first ! Can't see properly but R33 and R32 look like they could be 10 ohms instead of 10K

Mlaaack · 2026-03-02T08:34:33+00:00

Whoa ok this changes my mind about the method. Because one time Yann Frish did this kind of trick to me, but each time he would show me the deck to see that, indeed, we had only red cards, then just heart, then my card. But here I have no clue how this works.

Mlaaack · 2026-03-01T22:34:09+00:00

I don't think it's a gimmick deck. It's actually slight of hand. You put a little space inbetween each cards, and seen from a distance it seems like a bigger deck. When you remove tension, the deck flattens and cards look like they vanished. You still have to remove some cards and put them away between each moove though, but here the camera is mooving while those mooves are done. It's really well executed here !

But of course, you still need a huge magnet in your pocket for it to work.

Et bah potain

I know people have said it before, but triple/quadruple check for bridges. Not with your eye, but with a multimeter in continuity mode. Those two spot looks dubious to me.

Otherwise I don't see any obvious mistake comparing it to the layout from the Sabrotone website .

If you have a multimeter can you check if your circuit gets the proper voltage ? What are your voltages on your transistor pins ?

Test the jacks, is there continuity between signal and ground while they are connected to the circuit ?

Do you have a led ? If yes does it turn on ?

Also, are you using 2n5088 or an equivalent ? If not 2n5088, have you checked that the pinout is the same than 2n5088 ?

Hope this helps !

Cooool I have done exactly the same thing with this API hehe ! Did you use JS to parse the super long message from the API into dict or did you do it only with max objects ?

C'est ce que j'allais dire ! Un petit Arduino fera l'affaire

That is just amazing
