vreau sa fac rost de o imprimanta 3d, de multe ori am nevoie de piese mici, un adaptor ceva care trebuie sa il comand din china si sa stau saptamani dupa el. as rezolva mult mai rapid cu o imprimanta 3d. ma gandesc ca sunt foarte scumpe, nu le am deloc cu astea, nici macar nu m-am uitat de curiozitate deoarece poate vad una ieftina si sunt tentat sa o iau iar apoi vad ca e gunoi. daca ma puteti ajuta, poate are cineva si se pricepe unde as gasi, pe unde sa ma uit dupa una. mersi

i know nothing about 3d printing. all i know is that i need one. what is the cheapest 3d printer that you can actually use and print something? i hate that if i need a little piece or adapter i have to buy it from china and wait weeks to get it when i could just 3d print it and have it in few hours. even earlier as there is probably a file out there with everything already done, no modeling needed from me.

i’m looking to build a big speaker, and i want to power it using tool batteries. the amp that i’ll use performs the best at 24 volts, and the tool batteries i have are 18v. i want to add a boost converter to always have 24v at the amplifier no matter the charge level of the battery, so i can always get full power. the voltage range of the battery is between 20.8v when fully charged and it cuts out at 15v. i’ll use a 50w stereo amplifier, so i need a little over 100w of power. let’s say 120w, which is 5 amps at 24v. and that’s going to be about 6-8 amps from the battery. is there such board that is good enough to be able to operate at those conditions and not drop the voltage at short peaks, like when bass notes hit? if anyone has used such converters

i’m debating whether to keep my ps5 offline on 13.00 or just update. i was on 12.7 but my dumbass sister updated to 13.00, at least i didn’t agree to the new terms so i can just play it offline for now, since the games don’t have that 30 day license. will we see any jb for 13.00 this year?

i need a high power 4 ohm resistor so i can test the output power of audio amplifiers. i can’t find any over 50w that would ship to my country. i could get 2 8 ohm 50 watts and use them in parallel but what if i just wind a long copper wire on some rod or something till i get 4 ohms of resistance? or i’ll need like 50 meters of wire?

vine bacu iar eu sunt praf la mate. in ambele simulari am luat fix 2.10. la judeteana nu invatasem nimic, iar la cea nationala am mai facut ceva pe acolo, aparent degeaba. care sunt sansele sa pot scoate de un 5 pana la bac? de unde incep? la romana luasem 8.50 si 5.10 (nu am facut subiectul 3 la a doua simulare) si 3.40 respectiv 3.65 la fizica.
la ce ma descurc sunt matrice si legi de conpozitii, deci pot scoate ceva puncte din subiectul 2. la restul ma uit ca boul la poarta noua

comand de multa vreme din china ca e mai eftin ca la noi, si cam tot timpul imi era livrata de fan curier. dar acum vad ca e livrata de cargus. s-au miscat destul de repede baietii, avand in vedere ca a ajuns pe 1 in tara, iar astazi era in curs de livrare. dar, in jurul orei 12 am primit notificare ca au confirmat redirecționarea coletului la un punct de “ship&go”, ceea ce eu nu am facut. e intr-un oras in care nu am nicio legatura, nu am motiv de ce l-as trimite acolo. in fine, am intrat pe chat ul lor din aplicatie, am vorbit cu o persoana de la suport si mi-a zis ceva de genul: “voi trimite prin statie la agentul de zi sa trimita coletul la adresa”. dar acum, la ora 5 seara am primit alta notificare cum ca ar fi ajuns la punctul de ship&go in acel oras, si ca am pana la ora 10 seara sa il ridic. pe chat nu mai raspunde, doar botul, daca incerc sa dau de un agent intra mesajul generat ca e 1 mai si au zi libera. ce pot face?
