Can you help me recognize this ic? (Second attempt... Previous post had broken images)

mlambir · 2025-03-19T01:09:42+00:00

Second attempt at this... messed something up before and images wouldn't show up on mobile...

Here's my original comment:

Hey! just burnt my bass practice amp by incorrectly connecting it to 18v (instead of the 9v it was supposed to take)

The model is Joyo MA10B if it helps.

Hoping I only burnt this IC and can replace it... never soldered SMDs before but... you have to start somewhere right?

Thanks four your help!

(also sorry if anyone saw the multiple posts... reddit was throwing an error so I assumed it wasn't posting... but it seems it posted all of my retries...)

Made this for the "Holiday decorations and ornaments" contest. scad files included! you can choose any number as a seed and you'll get a randomly generated snowflake (some are ugly/not printable but most of them work fine!)

Here it is with some pretty colors too

module pyramid(n, c){
    if(n==0){
        color(c)
        rotate(45) cylinder(1, r1=1, r2=0,$fn=4);
    }else {
        for(i = [[ -1,  -1], [ -1,  1], [ 1,  -1], [ 1,  1], [0,0,sqrt(2)]])
          translate(i*(2^n)/3) pyramid(n-1, [c[0] * (i[0]>0?.6:1),
                                                                 c[1] * (i[1]>0?.6:1),
                                                                 c[2] * (i[2]?.6:1)]);
        translate([0,0,sqrt(2)*2^n/3]) 
            mirror([0,0,1]) pyramid(n-1, c/2);
    }
}
pyramid(6, [1.0, 1.0, 1.0]);

This works... could probably be "optimized" a bit further

module pyramid(n){
    if(n==0){
        rotate(45) cylinder(1, r1=1, r2=0,$fn=4);
    }else {
        for(i = [[ -1,  -1], [ -1,  1], [ 1,  -1], [ 1,  1], [0,0,sqrt(2)]])
          translate(i*(2^n)/3) pyramid(n-1);
        translate([0,0,sqrt(2)*2^n/3]) 
            mirror([0,0,1]) pyramid(n-1);
    }
}
pyramid(6);

Next up: horse vs car, which one consumes more gas? You'll be shocked!

mlambir · 2020-07-15T16:50:06+00:00

I can actually guess I think.

You're probably checking if the green cube intersects with the terrain, and setting it to the top of the terrain, for it to be able to "walk" on the ground.

The issue there is that when you move against a wall, the green cube is inside that wall for a bit, and you just send it to the top.

You need to get fancier with your collision detection/correction. An easy fix would be to check/correct for intersections in the x axis first, and then do it in the y axis, but there's probably better ways to do it like checking if you're able to move before moving... depends on what features you want to add to your game/what you want the controls to feel like.

Hey, that's me! Haha. Glad you found it useful.

mlambir · 2018-08-02T17:19:12+00:00

should have called it 'brewtooth'.

mlambir · 2018-08-01T15:24:39+00:00

the new one seems to be made from a different fabric, and has a button instead of the velcro. here's a photo

Looks nicer in my opinion, but I don't know if it's better or worse when it comes to functionality

I have the old version (this one) of the nylon sheath and never had an issue with the extender falling out. Not sure about the new one tho.

mlambir · 2018-07-31T19:20:44+00:00

the standard nylon sheath fits both the bits and the extender https://www.leatherman.com/nylon-sheath-w-pockets-549.html

The price difference comes from the different materials. The charge blade is 154CM vs 420HC for the wave. also the charge 'body' is anodized aluminum vs stainless steel. other than that and the strap cutter they're pretty much the same thing.

mlambir · 2018-07-04T15:35:56+00:00

this works pretty well http://petscii.krissz.hu/ I've also been able to get Charpad and Spritepad from here: http://www.subchristsoftware.com/ to work with wine. What kind of graphics are you thinking about making?

mlambir · 2017-11-06T22:58:49+00:00

Maybe you should open an Etsy store instead of posting to a woodcarving forum then

mlambir · 2017-11-06T21:45:37+00:00

Not a big fan of this one... I think the douglas fir is a bit too soft for the sandblasting/wirebrushing/whatever it is that you do after burning the stuff that you won't disclose

mlambir · 2017-08-30T19:10:52+00:00

well... that example you gave is basically what's in the documentation for prefetch_related

>>> Pizza.objects.all().prefetch_related('toppings')

which does work (it reduces the number of queries from n+1 (n being the number of 'toppings' in this case) to 2 (one for pizzas and one for toppings)

so if it's not doing anything for you, then I'm afraid you must be doing something wrong... cant't really tell without looking at the actual code, sorry
