Raspberry Pi credit-card sized computer

  • good day mga sir,hobbyist
    tanung lang may for sale na kaya sa pilipinas na hifiberry DAC+ para sa RPI,
    thanks
  • @eightdot29
    Sadly, mukhang wala. Naghanap na ako sa tpc, olx, rocksoftech, somasegar, etc.

    Meron sa ebay na mga DAC modules for RPi, pero di ko alam kung reliable sya.
    Si Hifiberry din kasi may case na din binebenta na sakto na ang dimensions para sa RPi + Hifiberry.
  • hello to all

  • Hi mga ka RPI.

    Sino Sa Inyo may hdd ang RPI nyo?
    May acrylic case or case ba Ng RPI na may had cage?
  • ^Check out Plusberry pi po.
    May nakakonek na hdd sakin pero nakamount sa pader kasama nung Rpi ko.

    Ang ayoko lang sa plusberry eh slanted yung pi sa loob, kung b+ na yung gamit nila pwede na ilagay sa corner yun dahil 2 corners na lang ang mga ports. Yun nga lang yung cable ng hdd nakalabas hehehe.
  • setting up a new headless system using raspi b+ from scratch (instruction from my head) using ArchLinux. nakaka yamot mag compile sa debian (wheezy debian aka raspbian).

    At least setup na ang autofs + samba + minidlna + rtorrent+rutorrent (for automatic weekly download goodness) + transmission.
    Next na yung pyload pero saka na yun.

    Using my rasp 256mb for IPTV purpose, eg, just storing IPTV recording from my with 2TB HDD attached on it with UPS communication so raspi can shutdown gracefully when 15% battery na yung UPS.

    For now, yung b+ is powered by CW5356u USB for power source. Yun nga lang b+ still sucks when it comes to USB current, parang useless din yung more usb ports with this. still under rated 600ma yung ports ng raspi, not unless I bridge the polymer fuse which is dangerous. Yung Dlink USB hub ko naman ginagamit na ng isa pang raspi ko for power source sa raspi at usb hdd.

    testing transmission download cpu usage and memory usage at the download speed of 250kbps (2mbit). So far so good.

  • @polka
    Sabi po nila pwede taasan sa config yung power output nung USB ports ng b+ up to 1.2A <click here for link>
  • planning to buy a raspberry para sa monitoring ng cctv.

    may naka try na ba dito? ok lang ba raspberry for 24/7 operation?
  • Ok po sya 24/7, pero depende po sa cam na gagamitin kung malinaw o hindi yung magiging kuha ng cctv program. Yung generic na usb webcam na ni-recycle ko (na nabili ng kapatid ko sa cdr king 4 years ago) malabo kuha ehehe.
  • @ormoreno

    Thanks bro. May available BA nyan dito Sa Pinas? Wala ako Makita Sa olc at Tpc e. Sa eBay plum berry lumalabas haha.
  • ^Naku wala po sir, oorderin pa sya galing Israel ata, may $10 na shipping fee.
    Kung marunong lang ako mag autocad, lapit sana ako kay sir Cham_E_Lyon pagawa case katulad nun..
  • mukhang gusto ko yan, kaso nung tinignan ko, puro pre order pa lang ang meron.

    so yeah, kahit umorder ako ngayun, sa January next year pa daw ipapadala.
  • Although may point nga naman yung promotional vids nila, it's convenience/time vs savings.

    On one hand nandyan na lahat, di na bibili ng cables/parts/accessories, papagawa ng custom cases, etc.

    On the other hand, mas makakatipid kung DIY (sakit lang sa ulo siguro yung custom case ehehe). Yun lang lakas kaen sa oras.

    May mga prototype case/board na sila sa Updates section nung indiegogo site nila.
    May IR sensor na din and on/off switch.
  • Kulang na lang sa enclosure nila is ventilation. With hdd inside hindi malabo mag overheat yan. Lalo na pag gagamitin 24/7.
  • Sabi nila lalagyan din daw nila option for fan, connected sa gpio. Sana standard size para pwede palitan.
  • maybe they mean yung fan sensor is connected sa gpio, pero it still relies on 5v power source dun sa main circuit ng plusberry. hindi kasi advicable na kumuha pa ng power source ang fan sa raspi.

    anyway, here thinkering my raspi's b+ USB current adjustment, for some reason, in Arch Linux hindi gumagana yung tweaks para mapataas yung current ng usb, and a little research leads me to that after the update sa firmware ng arch linux, automatically pala max out agad yung current ng usb once arch linux is started (as long as updated yung firmware nya). Measured it with my digital meter and it seems that my limiting factor kung bakit hindi pumapasok lahat yung full 1.8amps sa raspi is dun sa USB cable ko (samsung OEM USB mini cable) rated lang yung cable to handle at least 1.04amps. Kaya kahit gamit ko yung spare OEM Apple USB charger rated at 2.1amps dito eh wa epek. Now using USB mini cable na galing sa PS4 and that fix the issue. :) now my pi is able to spin up my 2 USB HDD drives. Mahahalata mo nga lang pag nag start yung pi, pag start yung 2 HDD is not spinning at all at with some weird clicking noise that means ayaw mag spin up ng drive kasi konti yung power, after a few seconds ayun nag spin up.

    My Pi setup is consuming 7-9watts of power.
  • ^May delay po? Sabi nga po sa forums ang dependancy daw eh dun sa power adapter na gagamitin. Pero good to know kahit may delay gagana. 2 HDD pa. Ano pong hdd yun pala? Yung mga portable or yung 2.5" na may enclosure (e.g. cdr hari)
  • thanks mga sir! siguro mag DIY nalang ako :)
    gamit ko kasi ngayun is acrylic. eto kasi sa akin ngayun <click here for link>
    acrylic nalang din siguro. para may pinakamaliit na fan din. iwas over heat. 24/7 kasi nag run sa akin simula nung binili ko.
    so far so good. pwera lang sa usb thum drive ko na naddisconnect minsan nag popop up sa xbmc sa lower right part. di ko pa din sya naayus :)
  • yes, at start naka default sya sa 600mah current (shared across all 4 ports) so at some point arch linuix is adjusting something on my raspi and boom, it automatically set current to 1.2mah

    yung 2 hdd ko is yes naka enclosure lang since mas makakamura ako sa ganon, each drive is powered at 400mah using seagate 1TB laptop drive.

    pero sa debian wheezy (aka raspbian) you need to set it to boot configuration. or set by thinkering on gpio setting. I actually had a tester that can measure this things, at bootup mag power up yung usb for about less than a sec (my meter cant measure that short power up) tapos after a few second for 5 seconds current nya is limited to 578mah. tpaos bigla nag spike sa 1.1xah something and that spins up my 2 drives. And the red light is still lit up, unlike noong gamit ko pa yung Samsung OEM, blinking sya pag nagsaksak ng HDD.
