They aren't dropping AVR at all from what I can see. There is only one through hole design left, but there are plenty of 8bit AVRs there. Got a link to some article showing our claiming they're ditching AVR?

This. Part of the appeal for me has always been how quickly and easily I can use AVR's attiny, 328p, mega, etc.

I'm doing great with my box of 328p's and quick & easy single sided photoresist PCBs.

Fuck BGA, too unfriendly to hobbyists.

cavity-molar.png
266 KB,
Hey 4chan i was wondering about filling in a cavity at home. Is there a way to fill it in safely and if there is how would i do it? Would using that filling replacement from walgreens work? and how would i clean it out so that i dont create a cavity under what i filled in?

Also pic not me, but is similar to what i have.

No.

But since you want to do something wrong and cheaply, you might as well rub some white epoxy in there for shits n giggles. Then have it removed at the dentist like you should.

>>940005
I remember someone died from giving themselves a root cannal with proper equipment.
Was not in a clean environment.
Died fron a severe infection.
>>
Your options are:

If the cavity is small, heal it.

If the cavity is large, pull it.

OR

Go to the dentist.

shitty arcade stick.jpg
38 KB,
hi diy, i'm considering building my own arcade stick both for a school project and for myself to use since i play mostly fighting games and i don't wanna buy a stick for 100+ dollars since those pieces of shits are overpriced.

I'm wondering where i could find cheap parts to use to build it since i have zero knowledge about where to buy and wherever i check parts go for a lot, but it really wouldn't surprise me if you could build your own stick for a lot less than almost 100 $.
Any suggestions would be appreciated whether sarcastic or sincere :)

Hello /diy
So here is an idea of mine.

i was wondering if anybody has tried this before, or if its possible at all.
joining two chargers into one.
It would be ideal to somehow splice for example the 10.8 v charger socket somewhere on the 18v charger!
preferably on the side of it. So that its possible to charge both batteries at the same time.
has anyone ever tried this?
and do anyone have any good idea on where and how to place/fasten the socket?

>>
>inb4 duc-tape or glue.

the intention is to end up with one charger, preferably not much bigger. with one cable and both sockets
>>
im not really sure why they dont make em like this in the first place, no reason that i can think of.
the 10.8 V has a 7.2 output so why not just make an all in one charger
>>
for the very obvious reason that some doofus is gonna plug a low-voltage battery into a high-voltage circuit and it's gonna make a big ka-boom.

Actual mods if possible. I use an overdrive pedal to boost distortion but it seems that the amp crunch and od clash and sounds horrible.

an idea ist to lower the negative feedback in the preamp stage. also you may try switchable diode - clipping between first and second stage; worth trying.

Hi /diy/,

I want to build a very specific thing for my sound setup.

I'm pretty good with soldering stuff and following instructions as well as doing conversion things - but I never really built anything "from the ground up", so I have a lot of questions but really look forward to do this.

Basically I want to put a soundcard and headphone-amp into one unit, but also want a few special things:

-has to have mic-in
-headphones and (balanced) pre-out have to be usable at the same time
-completely passive but regulatable rca-in to balanced/unbalanced pre-out

(I'm planing to use that with my active speakers that accept balanced in: M-Audio BX8 D2)

of course I could buy a few different devices and chain them together to get all of this working, but why not simply diy my own solution to only have one device and no cable clutter ... also, I want to build it for fun

my plan is to order a bunch of connectors and potentiometers for the front/back panels and some off-the-shelf hardware for the three internal components (which I'd rip apart to arrange their internals in my build, soldering everything together with some wires).

I need help with selecting the right components and especially what kind and resistance of potentiometers I'm going to need.

here's my plan so far:

-audio interface: random decent USB soundcard stick with 3,5mm in and out (any recommendations for a cheap one that doesn't suck? has to be plug'n'play, no drivers)

-headphone amp: a stereo amp kit from ebay or something. the amp obviously needs some power (I haven't put that into the mockup-schematic yet)

-DI unit: likely the Behringer MicroHD HD400, because I have one and it works well


any recommendations for the usb sound card or some other things I haven't considered or should watch out for?

my desk setup
but also simply to build it for fun


anyone having any idea what kind of potentiometers (resistance) I'd need to regulate one: line-level audio and two: "amped headphone"-level audio ?

Guys, I've been looking into building a smart mirror just to show weather, e-mails, maybe twitter for the news and some other basic stuff to read while I get ready to leave the house.

I know it's a double-sided mirror with a monitor and some other stuff. My question is: how do you make the monitor show what you want? Is it a web-page you assemble with a black background and keep updating the information as needed or is it something else?

Thanks!

In the old days I'd spend hours collecting old computers and pulling transistors like this out of them because the only other source was radioshack where they were a couple dollars each. They cost pennies now so it doesn't make sense for anyone to salvage them. The electric bill from running my soldering iron would cost more than the component I used it do desolder.

Some things like large switches, stepper motors, and transformers are still worth salvaging, but not diodes, LEDs, resistors, capacitors, ICs etc.
>>
>>943226

I find desoldering as relaxing as soldering, so not only do I get shitty 10-year old capacitors that are 10% of their rated capacitance, I also have a chance to relax.

I need advice on buying a tool. A tool that no one likes to use. I need a new vacuum cleaner.

I live in a house with a Labrador Retriever, low pile carpeting, wood floors and a lot of foot traffic. I need a vacuum cleaner that can pick up shit on bare floors and pull out dog hair that in embedded in carpet. This is the current vacuum I have and its brush is useless so it just rolls right over the dog hair. Any recommendations?

I picked up a shark navigator a year or two ago and I'm pretty impressed with it. I only have 3 rooms with carpet and it works amazingly on those but it's even better on my hardwood floors. I've recently used the attachments for the first time on my vehicles and they're pretty handy for tight spots.

Only bad thing I have to say about it is hair got caught in the roller once and I had to clean that out. But that happens with all vacuums that I've had and it took less than 5 minutes. I have a cat and a dog btw.
>>
Uhh, instead of using a vaccuum, save money & go to Dollarama & but duct tape & use tape on ur carpet takes alot more out then a vaccuum & it doesnt wreck ur carpet nor does it leave messy patterns its a great diy lmao

I've decided I'm tired of using chinkshit precision screwdrivers to tear apart chinkshit electronics and I want to spend some money on a gud set. The rest of the internet seems to think Wiha is the best but what does /diy/ use? Do you use multi-bits or traditional?

>>942339
I only use multibits for the random shit (read as torx). Wihas are good, but overkill if you're not working in high voltage environments. This is one of those deals where most all mid level does just as good as high level as long as you don't need the additional safety features of high level stuff...

no point in using good stuff on cheap shit

wiha is good but for the price you can get 10 of the cheaper stuff so why?

I'm with OP on this one. I got some Wera ones, they're pretty good. Never used Wiha.
