Thin Client Wysens Up To Become OpenWrt Router

For some of us, unused hardware lying around just calls to be used. It seems like [Miles Goodhew] heard the call, and wanted to put a Dell Wyse 3040 thin client to use — in this case as a wireless router. It seems simple enough. OpenWrt supports x64_64 targets, and the thin client has 2G of ram and 8G of flash. It should make for a very capable router.

And before you tell us that it’s just another computer, and that installing OpenWrt on a miniature x86 machine isn’t a hack, note that there were some speedbumps along the way. First off, the motherboard has integrated storage, with the not-very-useful ThinLinux installed, and the system BIOS locked down to prevent reinstall. There is a BIOS clear button on the system’s diminutive motherboard. With the BIOS lock out of the way, a real Linux system can be installed on the small 8 GB mmcblk device.

The next issue the the CPU. It’s an Intel Atom x5 z-series. OpenWrt won’t actually boot on that oddball, not-quite- processor, so [Miles] opted to install Fedora and test via virtualization instead. If that statement makes you do a double-take, you’re not alone. The initial explanation sounded like the mobile-centric processor was missing instructions to make OpenWrt run, but virtualization doesn’t add any instructions for a guest to use. It turns out, the problem is a missing serial port that OpenWrt uses as a debugging output by default.

After a custom OpenWrt compile, the device comes up just as you’d expect, and while it would be underpowered as a desktop, OpenWrt runs happily shuffling bits from Ethernet to wireless adapter at respectable speeds. As [Miles] points out, there’s nothing ground-breaking here, but it’s nice to have the details on re-using these machines compiled in one place. And if you too love the idea of putting OpenWrt in places where nobody intended, we’ve got you covered.

Thin Client And Smartphone Step In For 3D Printer’s Raspberry Pi And Touchscreen

It’s no secret that Raspberry Pi’s are a little hard to come by these days. Unless you had the foresight to stock up before the supply dried up — and if you did, we want to talk to you — chances are good that you’ve got a fair number of projects that use the ubiquitous SBC on indefinite hold. And maybe that’s got you thinking about alternatives to the Pi.

That’s apparently what was on [Crimson Repair]’s mind lately, the result being the discovery that an old thin client PC makes a dandy stand-in for a Raspberry Pi, at least in some cases. The video below is on the long side, true, But it’s chock full of command-by-command instructions for getting a Dell Wyse 3040, a thin client that can be found on the secondary market for $25 or so, up and running as a Klipper alternative for a 3D printer. These machines, which usually see use in point-of-sale applications and the like, sport a 1.4-GHz Intel Atom processor and a couple of gigs of RAM, and the form factor is just right for tucking into the base of an Ender 3.

Getting one up and running is a matter of getting a Debian image onto a USB key and configuring the thin client to boot from USB. After that it’s a simple matter of installing Klipper and wiring up a buck converter to power the machine. It’s not exactly rocket surgery, but why muddle through the process when someone has already been down the path ahead of you? And if you want to take it further, the second video below walks you through all the steps needed to add a touchscreen using an old Android phone. With a 3D printed bracket, the whole thing is a nicely complete printer control solution.
