The first time we participated we achieved better results than what we expected, so this year I would like to try to convince some students to get some cheap devices instead of using only OpenWRT on virtualbox.
If we manage to make some students excited about hacking OpenWRT we may turn some of them into stable contributors for the long term, which I believe would be good because I haven't seen many young people hacking OpenWRT recently, they almost all end up working on javascript stuff (so inflated and so boring!).
So my question is simple: what cheap hardware can we recommend them to buy?
Keep in mind their age is between 13 and 17 and they come from all over the world, the most being from Asia (particularly India) so their budget will be very low (and they'll have to convince their parents to give them money to buy these devices, which may not be easy). The devices don't need to be performant. They just need to be easy to reflash with OpenWRT and should work decently to bring up an access point, an 802.11s mesh and similar things.
What about donated devices? I have 2 routers I could send if it would not cost to mutch. They are a wdr1043nd and a wd n750 I all so mite have a wdr3600 v1.5
@tapper thank you for your generosity, I think it may disappoint some students if some of them get donated routers and some other don't. Moreover, if they buy it themselves they are showing they really care about knowing more and maybe once they spent some effort to get it they'll feel more ownership, just maybe (I have a lot of bought hardware I never had time to touch yet lol)
It runs OpenWRT and can be repurposed for other uses.
A Pi Zero W, case, and SD card should cost around 20 and provide a bunch of educational opportunities beyond that of a normal router.
If you need a router though I propose a Nexx WT3020. It’s about $20, has 16MB of SPI and 64GB of RAM, and if you flash a custom bootloader it is essentially unbrickable.
Due to the I/O situation with ethernet sitting on the single USB port of all RPis and the SDIO connected wlan card, any RPi is a pretty horrible choice as a routing platform - you can get much better devices for the same price.
Depends on your use case. For educational purposes I think it would be okay. Plus when I travel the 900Mhz ARM beats the pants off a 360MHz MIPS when it comes to handling OpenVPN for building a bridge back to my home.
(if you can still find them) How about the xiaomi mi mini? Should be lots cheaper to get in Asia.
They're quite old but you can still find them in clearance sales.
I have 2 minis myself, initial root/flash is a tricky, but once you're past that openwrt is fully supported - comes with a USB port so you can always extroot if needed. (note there's also a nano 'youth' model with a USB port - but that one is only for charging, i have no experience with that model).
One of the challenges of programs like this is training the trainers. Reasonably long-term availability helps make sure things go smoothly for the end-user and their support. I'd tend toward a manufacturer with some history, a reliable supply channel, and ideally one that does more than just slap OpenWrt onto their product. I haven't tried their product myself, but the inexpensive (under US$20) GL-iNet devices have tempted me several times.
hey undef, what do you mean for tricky? Keep in mind this are teenagers, some of them may be skilled but we can't expect them to open the routers and connect the serial port, if they're not able to do that they would be disappointed, so easy to flash in this case is important.
Check some of the stuff from ZBT on Alibaba. Various levels of support OpenWrt support, a lot of it is already fully supported. They may even be willing to negotiate for bulk purchases if that's something possible to organize. Talk to Anna, tell her Nick from Australia sent you, she'll look after you.
Hi nemesis . Gl inet ar 150 it’s easy to open and connect to UART usb given the soldered pins, and teenagers have better sight to read the small prints aside the connectors. You need to buy the UART too but I think you can find them really cheap. I am sure they would enjoy the serial console too. It took me a good one hour to realize about the cable crossing !! Best P.
