They're really just a sign of how weak general purpose computing has become. Almost all uses of Raspberry Pis for hobbyist projects could and should be done just as well with the computers that you already own and already have running.
- _joel 4y agoNot sure my main PC can run at 2 Amps..
- mciancia 4y agoWell, seeing that most desktop PCs are running at 110V or 230V, I think it's quite easy to find something that will run under ~220W or ~460W ;]
- tambourine_man 4y agoParent probably meant 10W (5V x 2A)
- joshspankit 4y agoYou are technically correct :b
- catern 4y agoThe marginal extra energy consumption of running more stuff on your main PC is likely less than 2 amps.
- _joel 4y agoThen I'd need to run my PC 24/7 with no sleeping, to serve something so miniscule like DNS records from PiHole, just taking one example, to provide service for all the stuff in my front room and my pocket.
- catern 4y agoI'm glad you mentioned PiHole because it's exactly the kind of thing I'm talking about. Dedicating a Raspberry Pi to running a DNS server is silly. You could run it on your wifi router instead, or you could run it on the individual nodes. Either of those should be extremely easy. But practical general purpose computing has decayed (or was never really there?) so instead there's this silly PiHole thing where you just buy yet another computer and convert it into yet another special-purpose appliance because general purpose computing is so hard.
- _joel 4y agoNo, you can't. You can't load a list big enough in the memory provided on a small router and even then only one flashed with OpenWRT (or similar). There are lite versions but they're incomplete and lack the UI facilities and other options PiHole does. You want me to run a full pihole on my TV, laptop, phone, tablet? I have to administer all those and deal with the headaches of installation on all of those (if even possible in jailed envs). You say it should be easy, have you ever done it? Who says I'm just running a pihole on that too, you're making a hell of a lot of assumptions here. It's a media server, ssh bouncer, tailscale node and a lot more.
- titzer 4y agoBah. Most laptops don't have GPIO pins.
- catern 4y agoBut most of them do have USB ports, and: https://numato.com/product/8-channel-usb-gpio-module-with-analog-inputs/ https://numato.com/product/8-channel-usb-gpio-module-with-an...
- prashnts 4y agoCheapest version is 31$. Without internal pullups. Which means it's basically gonna bit-bang if you want to interface with SPI, I2C etc. I'd consider a raspberry pi even if it costs more because it has a _lot_ of I/O capabilities and starts at 5$. For a comparable option, consider one of the Pi-Picos, Arduinos with VUSB, or a USB-Serial board with extra GPIOS.
- ranger_danger 4y agoWhere are you finding raspberry pi for $5?
- dmytrish 4y agoI think they meant Raspberry Pi Pico, which is definitely not a microcomputer with Linux, but it has plenty of I/O pins.
- RachelF 4y agoYes, and the price of Pi's is now very high due to a shortage. A Pi 4 costs more than a second-hand tiny i5-4700 series with SSD and 8GB of RAM. Still the Pi has GPIO and PLLs which Intel-based boards don't have.
