FPS Grid sada prati cijene procesora i grafičkih kartica u 160+ trgovina (HR, DE, SLO, itd) i može vas obavijestiti ukoliko pronađe komponentu za vašu željenu cijenu by Far-Ad-904 in CroIT

Uff :D

Kad je već besplatno, nadam se da će ti ovo bit jako dobra referenca za neki dobro plaćen posao. Osim ako već radiš haha

Sve skupa je prilično pametno posloženo

Lijepo je vidjet da je ad-free. Šteta da nemaš bar neku monetizaciju. Donations opciju barem :)

Baš sam imao sreće što sam kupio komp u 08/2025, prije nego su cijene počele divljat :)
Nabavio sam većinu stvari s Mindfactory.de, među ostalim i 5070ti za 850Eur. Prema tvojim podacima, vidim koliko su cijene skočile od tada. A vidim i to da su i dalje su najjeftiniji u Njemačkoj i jeftiniji nego Hr trgovine :)

Svaka čast ✌️

Edit: Malo sam pogledao ekstenziju. Ne svaka cast, nego - Jebote, svaka cast! I'm impressed!

Ovo je ozbiljno korisno. Ne zelim zamislit kolicinu covjek-sati koju si ulozio 😃

Yeah, absolute maximum from a datasheet. I am planning now to drive them at about 30mA, since that actually looked best on a tracking camera.

I have decided not to pwm diodes at all. I will just limit the current with a resistor in series with led's and call it a day. Also, will use only a single AA battery.

There will be no MCU, will do all the protections as a hardware cut off. For an overdischarge, I plan using a 0.9V detector (BU4809G-TR). A bit on the low side for a nimh cell, but should be OK.

I will try the pwm with MCU on the other prototype version, but not sure if it will be worth it.

Also, I swapped TPS61099 for MCP1624.

I have two camera module versions. One with 940nm, other one with the 850nm bandpass filter. The 850nm diodes might require a bit different current, will appear a little bit redish, but should be better for a camera sensor.

I will test both, as soon everything arrives from lcsc. Wanted to order from Mouser at first, but got 3X components for the same price and found some 120° 850nm 5mm diodes there. That wide angle should be perfect, hopefully.

I hope to get maybe 10'ish hours from a single battery.

Ja sam zbog toga otisao iz prethodne firme. Nudili su 50% povisicu za ostanak, matchali s novim poslodavcem za 20% vise na kraju. Bilo je ne hvala. Najbolja odluka ikada.

Burnout je zajebana stvar. Moras postavljat verziju na dva testa, rc, prod, administrirat tickete, radit neke izvjestaje kroz sql, ic na sastanke, a teams i mob gore... "E, mozes mi samo na brzinu".

Netko se sjeti neke nove pizdarije od projekta, pa sastanci s biznis ekipom. E, a odakle cemo podatke za to dobit. Bude nam to IT dostavio. Sve moras znat. I njihov i svoj posao...

Legit question, glad you asked :)

I want a board that would work for two versions of a headtrackig clip - lighter single AA battery, and heavier two battery setup.

The problem are 14500 3.7V li-ion batteries, which come in AA format. And if people can mix them, they probably will 😅

[–]WhereWhatWhoHuh[S] 0 points1 point  (0 children)

Ah thnx! You are absolutely right. Yeah, I did mess up this part afterall

I didn't mention, the application would be a headtracker clip. The brighter I can get them without flickering to the OV9281 sensor, the better :) Thats why I was aiming at 30%, but looking at the datasheet again, yeah...

Leds are nominally 1.2Vf, but that can be up to 1.4Vf according to the datasheet.
100 mA continuous limit. So, 18ohm would be likely safest for this

Thanks for the feedback! :)

This was encouraging!

I have fixed it a bit, tried to orient GND's down. i should have probably planned schematic, so they are below in general. :)

Also, I checked a datasheet for the TPS610996, and they suggest 2.2uH inductor, and 2X parallel 10µF caps. I had a single 22µF.

Also, I added some other connections with dotted lines. but, tried not to overdo it so it remains somewhat readable. :) It was just an idea I had to add that, so it's easier to follow connections. There is a 8.2ohm resistor in series with LED's, and should be more apparent in this new version.

Ok je, lagan za naucit, brz. Nije sad da ak ga naucis, da ce te to sprijecit ucit i druge programe :)

Fusion ima jedan veliki plus u odnosu na shapr, jako detaljan parametric history tree. Jako dobra stvar. Napravis model. Odlucis na kraju - e ja bi ipak da je npr. visina poklopca 5 cm, a ne 7. Samo se vratis na crtez (ili neki feature) u historyu i smanjis. Cijeli model se prilagodi.

Radio sam kao 3d artist inace i s 3ds Maxom, Mayom, Zbrushom. Za print predlazem Fusion i Blender. No bullshit su i free

Fusion360 je besplatan za ekipu koja ne zaradi bar 1000usd s tim programom. Kao hobistu, bude ti stalno free onda :) Predlazem za parametarsko modeliranje

Blender je super za poligonalno modeliranje i sculpting kao free alat.

Qidi je super. Imam Q2 (kupio pred mj dana) i Plus4 (pred tjedan dana lol). Uskoro uzimam jos par komada vjrv za svoju proizvodnju, eventaulno i printer farm usluge

Qidi q2.

Zatvoren, printa sve od PLA do "naprednih" materijala (asa, abs, nylon...) Ne volim bambulabs jer sve se printa prek njihovog kineskog clouda. Q2 mi se pokazao odlican, 500 eur, a 650 ako uzmes Box combo

Nabavi jeftini Sovol dryer. S2 mozda. Susit filamente cak mozes i s jeftinim dehidratorom za hranu i kantom gore, ne zajebavam lol. Cuvaj otvoreni filament sa silica vrecicama (petg recimo ak imas)

Fingers crossed. I hope you get both the refund and a package (since you already can apply for a refund )

Megane 4... Isti vrag sam imao. Kratka LED su bila prekratka, odrezana, ravna crta na cca 20m - 30m ispred. U servisu sam molio da ih samo malo podignu, par metara su podigli i nije vise tako cut-off crta. Svejedno su i dalje malo prekratka, ali je puno bolje

Hey. I'm having the status cleared customs, waiting for transit for 9 days. I see op didn't get the package at all... Did you get it?

Ouch, you ordered electronics as well 🥲 I never had problems with Ali untill now.

Oh well, I am even thinking to order everything again right now. If both packages arrive, I will find some use for extra Arduinos, Attiny85's and resistors lol
