Jesus what could you possibly run to make the Pi so hot it needs cooling?

>>57751474
>>57751504
Does it need extra cooling?

I was using a raspi but it's a slow piece of shit for server usage so I bought an i3-2100 machine for $15 and use that now.

Might use the the raspi to mess with gathering data from sensors but besides that, it's gathering dust.

You blow air into the heatsink?

>>57752296
The heat from the chip disperses into the heatsink, and the heat transfers to the cool air running over the heatsink

>>57752296
yeah, it runs 20 to 30ºC cooler by doing that

>>57752319
Oh, I always thought the idea was that the fan extracts the hot air radiating from the heat sink fins.

10/100 Ethernet... Potential max transfer is 100 megabits

USB2.0 Max transfer rate 480 megabits.

USB3.0 10/100/1000 Ethernet dongle 1000megabits.

USB3.0 is backwards compatible to USB2.0 It will just have to be smart enough to only transfer a max of 480 megabits.

So usb3.0 10/100/100 dongle is potentially 4.8x faster than 10/100 ethernet port.

It has an oc'd raspberry pi3 connected to a 5V3A psu (i didn't want to have to carry an external everywhere), a custom made front panel with a 4-port USB hub, a custom made back panel with an HDMI and LAN ports, a custom controlled GPIO switch under the original RESET button that I use to launch a shutdown -h now command (the pi doesn't have a switch off button, and suddenly removing the power could damage my sd card), and finally a led connected to the GPIO that lights when the original power button is switched on. There's also a small opening on the side to access the microSD card, which has retropie 4.1 in it. I recently added an external antenna for better wi-fi and BT reception, and my last touch will be to add a stereo jack output to use it with headphones at night. All for less money than a fucking nes mini classic, with far better game support and a lot more fun to make.

What should I do with mine, /g/? I have two and one of those startup breadboard kits with switches, buttons, light-sensitive sensors, etc. Figuring out the breadboard stuff was quite fun, and I use C for GPIO access.
Making the NES that the other guy in this thread did wouldn't be difficult for me, but it's not something I care too much about. Should I make a drone?

I want to set up one of those cameras pointed at the sky 24/7 for nice timelapses and capturing meteor showers and such. I want to hook it up to my network and have it activate at specific times and take pictures/video.
I thought a pie cam could be nice for this because it's controllable through terminal. Is it's exposure and such good enough to take nice pictures of stars?

>>57757471
Have taken a look at scanners for that?

You can tear open a regular document scanner, get the scanners sensor into a position that points upwards to the sky.

Then all you need to is scan all night long.

Results look like circles, because the earth (usually to be found below you), spins around its own axis.

Can I plug any headset to raspberry than I know works on desktop Linux?

>>57757793
I'm pretty sure document scanners are more expensive than a pie cam. Also I want to take videos and proper colored pictures too, which a scanner sensor shouldn't deliver

I'm using the Arduino as a programmer for the Atmel 328P microcontroller. Basically using it as ISP.

Started by reading about electronics when I saw a nixie clock and got interested in it. Honestly, if you want to try something easier try numitrons first (they're only 5V) and will help you understand the Arduino environment and will help you understand shift registers, which you're probably going to need.

>>57755569
Why are the books blurred out?

I have a first gen RPi B (512mb)

It seems to freeze up and need to be rebooted frequently, usually very soon after booting.

>>57758737

>>57758737
pretty sure it works fine for youtube at 1080.

Unless you're talking about the zero then I have no idea.

I don't have a pi, but I enjoy ultralight weight programming for windows and 6502 programming on the NES.

Things like exe packing and disassembly, and hand optimization really interest me. I'm think about getting into cryptography and seeing if any contributions can be made with an emphasis on hardware driven optimizations.

Is this this an art now with no meaningful use?
Is assembly programming completely dead?

I once read -O3 can hack x86 so hard humans can't read it and with better results.

Hello OP here,

my raspberry is currently collecting temperature data from in and outside.
I have started a tumblr blog a few weeks ago, just to keep motivated. Now I just wanted to show current temperature on my blog, but apperently the tumblr api is shit and I don't want to make request on my raspberry, I want to push data to the blog.

What's the best blogging plattform ever? I dont want to rent a v-server :(

has anyone tried running a bbs on one yet?

currently learning Java, followed by C, and am considering a pi to do some projects and build up a portfolio.

If I write a program in Java, is it trivial to make said code function on linux, windows, Rasp pi, etc? What things should I be careful with if I want cross compatibility?

>>57772380
>If I write a program in Java, is it trivial to make said code function on linux, windows, Rasp pi, etc? What things should I be careful with if I want cross compatibility?
Only if you need system functions like file read, serial connection, or shit like that. Anything else should be really easily portable

>>57772425

>>57772380
Honestly, you'd probably learn more and be more employable if you learned cross-OS libraries and compiled to all of those than learning Java.

Java WILL get you loads of jobs, no fucking doubt about that, but the former will probably get you better jobs if you find the right employers.
Knowledge of "complex" programming tasks like that are pretty attractive. More so these days since multi-OS is gaining quite a bit of momentum. (especially in the server-space with hardware VM support explosion in recent years)
Of course, there is that part: finding the right employer.

>>57772761
Simpler to run?
Far easier to secure.
Far cheaper to run.
Sticks out, although admittedly in an already niche audience. But you'll still get the attention of pretty much most of them at some point.

ebay. Be prepared to wait about a month as Ivan needs to sober up enough to actually put it in the mail. These things actually ship from Russia, Ukraine, and other old world Soviet hell holes so you know they're authentic.

A lot of the front facing tubes are new old stock, but if you want the top loading tubes those are more expensive, typically like $5 a tube and they're used.

You can also get the Nixie style VFDs for ~$1 a tube and they're 15V aside from the heater which is 1.5V.

looks like overall low quality.

Why is linux a downside? Is it not made for it or hard to use the boards capabilities with it?
