wow didn't know there's so many rpi users here! biggrin.gif
i'm a noob to rpi, just recently bought a rpi2 and load up raspbian into it.
at the moment i'm using it for torrenting (transmission), file sharing, and my personal cloud storage (owncloud).

not sure what other stuff i can put on it yet...is there any central page for all the uses you guys use for your rpi2?

that you would have to PM the TS icon_idea.gif i guess a lot of ppl used the Pi as a media box?
*
i believe so, since there's even dedicated OS for media box haha!
but i mainly use it for torrenting since it's a low power device, better than running my rig just for torrenting.

used to do torrenting with the Pi,same setup as yours (transmission,file sharing).
after sometime,i have nothing to download,end up using it to test all sort of nonsense (Pi cluster, IoT stuff,lap timer..) laugh.gif
now its collecting dust

have u used it for your internet connection packet tracing?

Guys I am using my RPI2 to torrent. I notice that all my trackers have error after sometimes and I do not have incoming connection. My download speed and upload speed is running @ 0kb/s.

do you set port forwarding for the port that your torrent is using?
make sure that the torrent is a live ones? and not with 0 seeders.
also, what torrent are you using?

I'm using Deluge and all my setting is default.

I tried running the same torrent with utorrent on my laptop and it able to torrent smoothly.

PS: is there any better torrent to recommend? Most importantly it can be control remotely like Deluge.
*
then have you set port forward deluge's port for your rpi's ip address?
that's the only other thing that i can think of...

i just got my pi today.

bought a heatsink together but what do i use to stick it on?
*
does it have any thermal adhesive tape on it like those old school stick on heatsink on motherboard chipset?

but on a side note, i'm not sure if heatsink is required for rpi, i've read somewhere mentioning that the rpi could withstand quite a decent degree of heat.

Hi guys. I am looking for the pi zero but it seems all sellers in Malaysia has no stock. You guys know of any other sellers in Malaysia or overseas that have it for sell?

Hi RPi gurus and enthusiasts!

Just got an RPi3B delivered and spent a couple of hours hooking it up, installing Raspian and generally basking in the total geek of it. Haven't been this excited over a dinky computer since my first Sinclair ZX Spectrum (yes, do the math ... actually *that* old).

The main purpose of getting it was to try to log and eventually automate my home coffee roasting rig. For those who haven't looked into coffee roasting, in a nutshell it's apply heat to green coffee beans until they turn brown. Of course there can be a ton of artisanal art-vs-science stuff flying around, but the crux of it is burning beans few steps short of setting a fire.

The definitive reference software for coffee roasting is Artisan, which is free and Open Source, and lo and behold, there is a RPi version of it!

So now the challenge is getting it hooked up to the coffee roaster. I'm using a very basic stovetop drum roaster from Korea called the Kaldi Wide, which IMHO extremely decent for the price. However, it is a totally manual setup (even the thermometer is analogue) so true to the geek in me, almost from the day it was unboxed I've been modding and gearing up for a totally automated roaster, with the RPi at the core.

The main inputs coming in from the coffee roaster will be two temperature sensors (one for the beans and one for the heat source). Before I got the RPi I got a Mastech MS6514 digital thermometer, which actually cost more than the RPi (duh!). The small upside is that this device has a USB output which I understand can be interfaced to the RPi. I have hooked it up to my Ubuntu notebook and with very minimal config managed to get it to feed data to the Artisan software. So in the short term, I intend to do the same to interface to the RPi. In the longer run, I intend to hook up a couple of MAX31855 chips to hook up the thermocouples directly.

The main control output from the RPi to the coffee roaster will be to adjust/control the heat source. The idea is to continually adjust the level of heat so that the beans will go up in temperature according to a predetermined pattern (known as a 'profile'). Doing this manually requires a lot of experience with the roaster and the specific beans (each bean batch will have difference characteristics), and it is especially difficult to repeat a profile exactly.

Bigger/more expensive roasters have PID temperature controllers to manage the heat source, but the latest version of the Artisan software actually has a PID built in. Yay!!

So now comes the question: I need to control the AC pumping the heatsource (which is a heat gun, BTW). Currently I'm using an SCR Voltage Regulator, which looks like is controlled by a simple potentiometer. I rather not hack the voltage regulator, in light of the high power going through it (up to 4KW) so instead I'm looking at a stepper motor to twist the potentiometer. I have found some cheap stepper motors that come with ULN2003 driver boards meant for Arduino.

Will these work with RPi? Any pointers on how to hook them up?

Much much thanks in advance!

i've to say, your project is really interesting! i'd love to see photos of your equipments and set up (if any!) biggrin.gif

my rpi project so far is only attempts to make led display clock + temperature, i got the stuff but haven't got the time (and motivation) to actually tinker around with it.

Hi all, from KL or Selangor where I can buy a Raspberry Pi 3 Aluminium enclosure/ casing? Thanks

i think i saw a few casings in lazada. but the sellers there usually get their stock from taobao. if you know how to get stuff from taobao, it'll be much better.
