Bloody posted:i feel like your grounds should be tied together i tied the grounds together, j290 had me try some things like putting a blocking cap inline with the speaker etc, but nothing im doing is giving me any kind of signal on the other side of this fukkin chip, i bought two incase one was bad or i fried something, both do the same behavior and i've not wired anything up in such a way as to blow things (its also supposedly a "short protected" IC) kinda mad and frustrated, i have some other components to make a push/pull amplifier but i've never done anything that complicated and was really hoping to rely on the formfactor here, j290 & co. suggested i pull an amp out of some lovely pc speakers so im gonna go do that at some point today

bobbilljim posted:my idiot spare time project last night and this afternoon: attaching a fan to my dsl modem. see dsl modems are poo poo and i figured the lovely broadcom chip might be getting too hot sometimes. i got a heatsink for it as well (pictured) but i dont have any thermal interface poo poo currently so i just went with the fan for now. fan is out of an old psu, got some resistors from my old car cd changer so the fan is nice and quiet. anyway thought u all might get a laugh out of the pic 50/50 mix of super glue and thermal compound. epoxy if you want to commit

^^ nice recipe, ill see if the thermal paste that i had wasn't 100% chewed up by my dog. or i guess i could use mustardcheese-cube posted:if you actually went out and bought a modem made after the year 2009 you wouldnt have to worry about your house burning down idk just so you know i have a few other dsl modems some of which are post 2009, this was mainly for giggles

that chart w/ the mustard was entertaining but the scientist in me needs to point out that the thermal diodes on a cpu are usually only accurate to +/- 3-5 degrees so showing that mayonnaise gets your cpu 0.3 degrees cooler than monoprice arctic silver isn't all that meaningful to say nothing of 0.3 degrees making basically no difference at all to anything, also

why is programming PICs so annoying? why doesn't my code work? is is because you can't use an I/O pin without reading every word of the 300 page datasheet in order to find out which of the 5000 other pin functions are enabled by default even though that makes no sense (set a pin to output? haha it's still connected to the ADC input!)? or is it because the five registers for controlling the port are spread across five different memory pages and you forgot to change pages?

look i know the MAKER way to do it would be to put five arduinos in a 3d printed case and have them communicate via wifi and tweet results to a thermal printer, but all it needs to do is read two buttons and output pulses when one of them is pressed

Sweevo posted:PIC16 (actually a 12F1822, but they're all as annoying as each other tbh) PIC16s are the weirdest ones of them all, not suprising (the architecture is pretty loving old). PIC24, 32 and dsPIC33 are all pretty legit, the PIC18 is probably their best 8-bit arch.

Mido posted:could use some guidance on a dumb thing because im really really bad at electronics nad i thought i knew what i was doing with this component but i dont follow up: was able to solve the issue, basically this amplifier has a 40db gain, and the line out on my audio shield was high enough voltage differential on the signal that it was trying to amplify the input signal up to like 6000v or some insane #, i hooked up a function generator we had in the office and applied a -60db gain to to the output and lowered the amplitude till i finally saw an amplified signal come out of this fukkin amplifier the issue is that it might be trying to amplify it too much and want a super quiet signal which translates to noise  so i might not be able to use this NTE amp and will have to pull apart a PC speaker to get the LM amplifier out of that

i only use the finest freescale eclipse plugins to generate a loving labyrinth of C that gives me a few handy top level API methods to call into with so i can use my jlink debugger and a mess of pogopins and an enclosure to flash my 100pin qfp monstrosity which i will then accidentally overheat with my heat gun when im too lazy to use a fin tipped soldering iron and some simple tinning tricks

pic16s are super easy to program actually, last time i tried i got my SPI writing program to run correctly the first time about an hour after starting to download the IDE at 4 MHz it can still do two 3rd order polynominals to linearize my ADC inputs in a reasonable time (more than 50 times a second at least) and if i want it to go fast i can turn on the turbo and get 64 MHz from the internal oscillator you literally just set up the config bits with the IDE code generator thing, set up the clock frequency, configure the port directions, read the SPI section and set CKE and CKP for whatever you need to talk to, clocks for the SPI, then write to the SPIBUF register and wait for it to finish interrupts are all kinds of fun for things that need to be responsive, and are also not actually hard to implement if any of this is too hard then you might as well get a raspberry pi or a copy of flowcode

i got it working in the end. it's still dumb that PORTA, LATA, TRISA, and ANSELA are all in different memory banks though. also i wish it had the BTG instruction like the PIC18

oh god i never meant you should be using assembly, i just use the free XC8 compiler for my hobby projects i did PIC18 assembly in school and it really made me appreciate how high level C is by comparison, for loops are like magic after a month of assembly

For next project get a big, red button that says, "Press for dubstep" and then make it play dubstep when pressed. Like, super loud.
