peepsalot posted:I'm of the opinion that it is perfectly safe to use and would not be worth the hassle of returning and waiting for a replacement, personally. It appears that the pin was missing from the header before it was put on the board. What does that pin look like on the back of the board? You should be able to tell if a pin was there or not when the board was wave soldered or whatever. I would check the underside, but I've already got it up and doing half of what I'd planned and it's been fine so far. I'm not much on the ins-and-outs  of GPIO, I just know there's power involved somewhere.evil_bunnY posted:I'd return it on principle. I kind of agree, but like peepsalot said time+money+hassle. And even if it's something as small as a Raspberry Pi, I don't want to contribute any more to any Indochinese e-waste mountains than I can in my lifetime. E: quote for new page

That is what happens when you get the parts supplier that goes $0.012 cheaper per part but it turns out his parts have actually a little more "tolerance" than they should have. I wouldn't bother sending the unit back, it's perfectly fine if you won't ever need that pin.

Glue the case shut so you don't have any incentive to ever look at it again. Returning anything valued at less than $100 is a giant hassle.

I'm looking for some older Pis to build a Pico-8 appliance for my cousins. Anyone know where to get old used Pis for cheap? All I can find is eBay sellers asking for more than the cost of the Pi 3.

You know how spacecraft and sensitive military hardware will have three identical computer systems for vital things, where decisions must be agreed to by at least 2 of the systems independently in order to be done (the idea being that it's probably the 1 system that disagrees that has an error)? Try to rig up a system like that with your 3 idle Pis.

Anyone have cheap recommendations for HDMI monitors that are pi zero compatible? I'm thinking of testing some stuff out on a test display before fully investing in a HiDPI 10" display.

I'm thinking of testing some stuff out on a test display before fully investing in a HiDPI 10" display. The Rapsberry Pi GPUs are not really capable of handling resolutions above 1920x1080 well at all, due to graphical power and memory limitations, and the Pi Zero especially can't. Don't bother trying to buy an HiDPI monitor, stick with 1080p or lower.

Super Slash posted:... they've kept the USB connectors so close together, all they needed to do was shunt the left one about 3mm away from the other and it could comfortably fit most USB dongles... The Pi zero us a bit of a nuisance for connectors. I suppose it comes down to being a "hacker device". Ie work it out yourself! Or that's the impression I get. My zero is used as a full time RISC OS machine with a homebrew audio out and rtc board attached to the top. Works well but it can't reasonably fit in any case. The top board is also set up for easy rigging with Dupont wires. It's how I connected an SPI ethernet adaptor until the USB one arrived.

A missing GPIO pin makes you think counterfeit? It's probably just a factory defect since you could just hammer/solder a new one in, but if you aren't using it in the first place its a non-issue. Apparently the new Zero only works with the latest version of Raspbian, shame since PiBakery is super useful but its cool to now only need a power cable and no more wifi dongle.

A missing GPIO pin and shipped in shoddier packaging but yes. Do you think that a company the size of the RPi foundation has literally 0 QC procedures? It is hilariously easy to 100% automate finding defects like that. They're a ~$10million/year in sales company that sells nothing but these.

For a course this year, I have to make something with a raspberry pi 3. They haven't released guidelines yet but I have absolutely 0 ideas for anything that would be cool. It is a beginner class so I'm not sure how much they'll really expect but I'd still like to do something that I'd enjoy making. Any suggestions? E: The only thing I could think of personally would be something where it automatically chucks raws and jpgs in the right folders on my harddrive when I put my sd card in it, but that feels like it'd be way too simple, and not really use the pi. Also you could do it with a python script or something. underage at the vape shop fucked around with this message at 02:43 on Mar 8, 2017 |

Use a relay, lamp and a webcam to make a device that will flick a light on and off as rapidly as possible when it sees a person. You'll have to fiddle with the timing to see how quickly a modern CFL / LED bulb can be turned on and off without breaking.

Whatever it is, as someone who's done quite a bit of hiring lately, it should have a database, a front end, and absolutely post the source code on your github account online Some sort of fast food kiosk ordering system with the 7" touchscreen would be cool, and a way to quickly access your previous orders (to order again) using a 4 digit pin would be great. As a student, any project you work on that can be easily described over the phone and source code you can point to that proves you did it, is a huge win during a phone interview.

Any suggestions? is a weather station too cliche ? temp, humidity and barometric sensors are cheap enough, and you could database the readings and graph it on a web server. that would cover scripting, reading the GPIO pins, databases, web server stuff etc. once you have the data you can do other stuff like 'today is the hottest day since $whenever' and so on.

I have a camera/raspberry pi setup in my makerspace which I'd like to upload images to my hosting. My current thoughts with regards to security are to password protect the Raspberry Pi itself and then use SSH to send files from the Pi to my hosting. As far as leaving the login info to my hosting on the Pi, should I be worried about this? Is there some way to have it so the Pi can only have access to create image files on my hosting and do nothing else?

Yeah use SSH key auth for this, create a pi user on your file store with permissions to that directory, then take the Pi's ~/.ssh/id_rsa.pub and add it to the for stores authorized hosts file, then just SCP the file from pi to file host. Or use rsync?

This depends on how paranoid you want to be. Any common file transfer protocol that lets you write will also let you read and overwrite. You could rig together a program that takes input and writes it to a file, authorized by a shared secret, and not worry much if the secret was compromised. This may also be possible using the command option in authorized_keys?
