It appears that my landlords are throwing out their microwave. Should I grab it and try to make an EM cannon Y/N

lol that screenshot is garbage. I couldn't upload to imgur w/ firefox 2 newer versions of firefox tend to make win2k bluescreen this machine is very noticeably more responsive with dual cpus, even on win2k

Generally small GPS units like that use UART, so they probably just left the Rx pin disconnected because you don't really need to send data to the module Anyway I don't know about that specific model, but if you search for Neo-6M on AliExpress you'll get a pile of results for similar devices for about eight bucks.

yeah I dont think protocol super matters much, this is just for a diy data logger my colleague was interested in making more of. Size and power consumption are the main focus (that one is tiny af). Its getting strapped on the back of a turtle, or similar, if that gives you more context. I've also just sent an inquiry to buy it direct from the company. moron izzard fucked around with this message at 19:24 on Mar 24, 2017 |

yea, all the little standalone GPS modules i'm aware of transmit standard NMEA messages, and yes, you can change the data rate by sending it some commands. haven't really looked into it much cause many of the things only update position at 1-5hz so the default (usually 9600bps) is plenty fast.

i think my schematic is complete and i've got a preliminary layout routed and im probably not building this board because it's 4 layers and ~36 square inches which is gonna be ludicrously expensive anywhere (eg oshpark would be 360 dollars for 3) plus a ~$100/board bom plus chassis power supply lmao i did make a sweet timelapse of the process tho and i only forgot to record a few bits https://www.youtube.com/watch?v=6tsnFSZMZUY without the top ground plane poured it looks like:  (this is not what i would call a final layout but its most of the way there) Bloody fucked around with this message at 07:05 on Mar 25, 2017 |

i got my solution size down to 114x81mm on 4 layers by putting two of the inductors on the bottom layer.

you have to run certain updates in the right order for certificates to work out correctly or some poo poo. the guide I was going by said I would have to reinstall

it looks like if i bit the bullet and went to a two sided design i could probably cram this in 12 square inches which is a more tolerable price point hmm it'd be a pain in the rear end to assemble

i accidentally did something dumb with my nier:automata saves and needed to start over from scratch, but the cool combat skills are gated behind upgrade chips you don't get until later in the game. spent a few hours pissing around with the saves and a hex editor, documented the savegame structures, and made a simple editor in javascript as much as i love to poo poo on javascript, inside a modern browser with file + binary blob apis, it's quite powerful and fast to prototype with. i knew nothing of the apis and still got this running in about 90 minutes

poo poo yeah my current idiot project is like 40% completed. This is a wired car stereo remote I'm trying to turn into an IR one that can talk to my new system thanks to longviews advice I managed to have most of the switches working but i've been stuck for days trying to track the 3 way switch wheel movement but couldn't tell why one of the transitions would always gently caress up. eventually found out i had spurious intermediate states that would mess up my logic the circuit is pretty simplle  now it's all hooked to a cool attiny. i've had people yell at me on forums that "u dont have enough pins, you idiot!::"  i still need to get the signals off the knockoff aliexpress remote i have on the way, get my circuit to flash them correctly, filter and power from 12V etc etc

I'm shocked that the response to you using a microcontroller was "you need a bigger one with more pins" and not "lol you stupid baby I could do that with two resistors and a cat-whisker diode"

unpacked robinhood posted:tbh it was on a microcontroller forum and it was kinda my fault whats the power draw of your circuit (ballpark)? if its mostly just the microcontroller, then its probably like a few milliwatts (milliamps). then the efficiency penalty of your linear regulator is basically just (output voltage)/(input voltage) and then well if your load is a few milliwatts you're probably just fine

Microcontrollers are fantastic. Every time there's a moderately simple mcu project on Hackaday the comments just fill up with thousands of obnoxious grognards moaning about how "shoulda used a 555!! overkill!! Arduino more like stupidino!!" and I loving hate it an Attiny85 costs roughly the same as a 555 in a dip package, requires zero external passives to emulate a 555, and can do a thousand times more stuff on top of that.
