Vorbis decoder chip on SparkFun
I'm open to flames if this has already been posted. http://www.sparkfun.com/commerce/product_info.php?products_id=8300 As of April 17th, SF listed a new Ogg Vorbis decoder chip that is seriously listing for $10 USD. I'm excited. I think I'll buy a couple and integrate them into an IR streaming project I've been tinkering with. -Chris Harrington

Tripp-Lite SMART1500LCDT
I've made some progress getting this Tripplite to work: http://gathman.org/2016/07/30/Standard_Schmandard/ Basically, plug it into a USB hub that actually implements USB2.0, then power cycle the port when it hangs. It does seem to be a hardware problem with the USB controller. On 05/24/2016 09:06 AM, Charles Lepple wrote: > On May 22, 2016, at 10:18 AM, Stuart Gathman wrote: >> I

FE700VA over USB? controlling UPSes over network?
    Lately I replaced my 10+-year-old server with a nano-ITX-type one that has USB but not old serial ports.  I connected my FE700VA to DB25-to-9-to-USB cables, but haven't been able to set it up. Apparently my DB9-to-USB cable (Prolific Technology, Inc. PL2303 Serial Port) has issues needing old software (setserial?) and some new software (fconfigure) being changed.  Has anyone managed

Why are LAN ports not standard on UPSs these days?
...a good job of power filtering. I use a NUT master running on a Raspberry Pi 3 which is easy to maintain and gets current updates via its Debian roots. I have two environments, one with a much older UPS which has only serial, but the addition of a tiny card with a MAX3232 level-shifter https://www.sparkfun.com/products/11189 allows the RPi to communicate nicely, the second environment uses a USB connection from the RPi to the UPS. Both work very well with NUT, and then communicate with NUT clients on the other systems. I like that the RPi allows me to separate the NUT master function from the main...

Why are LAN ports not standard on UPSs these days?
People, A couple of decades before I was retired and was still working for other people I had cause to install UPSs and they usually had RS232 ports to allow the setting up of shutdown scripts to UNIX / Linux servers. Now, after not having to be concerned by those issues for some time - most of my little web sites have been on Digital Ocean or other suppliers VMs for a long time - I am

New ZFS Intent Log (ZIL) device available - Beta program now open!
The DDRdrive X1 OpenSolaris device driver is now complete, please join us in our first-ever ZFS Intent Log (ZIL) beta test program. A select number of X1s are available for loan, preferred candidates would have a validation background and/or a true passion for torturing new hardware/driver :-) We are singularly focused on the ZIL device market, so a test environment bound by synchronous writes

NUT - General Concept Question
I've been looking over the documentation and several installation guides for NUT, and I'm starting to get a little bit of a feel for what it is. But I'm still not clear whether what I'd *like* to accomplish is actually practical using NUT. Perhaps someone here can tell me if they've done something similar, or if I'm way off base. I would like to set up a Linux host as a
