Red Hat Enterprise Linux and the closely associated CentOS Stream 9 remove a lot of legacy kernel modules from their kernels. This seems to also include removing sources from their distributed kernels.

I wanted to add the scsi/bfa driver to support Brocade Fibre Channel adapters, this is mainlined but not part of the RHEL kernel sources.

This one's pretty simple.

This is a basic teardown of my old cable modem.

The EPC3010 was the basic modem supplied by Get.no, a former cable internet/TV supplier that was bought out by Swedish telecom giant Telia.

After some hard drive failures I decided to up my backup game, and ended up buying two LTO-5 tape drives.

This is a collection of what is required to put a HP Z420 and (probably) Z620 motherboard in a new case.

This is a cute little clock intended for OEM precision timing, let's look at how it's built.

The D-LI90 battery is a fairly standard DSLR battery used by Pentax/Ricoh for most of their medium to high end DSLRs from the last 10 years or so, including the K-7, 5, 3, and 1. Since I started using my 300 mm F/4 lens I've noticed that performance across my…

This article is about modifying the HP 3456A voltmeter for 50 Hz operation.

I bought a used Icron USB Ranger 2212, and took a look at how they implemented the Cat5 extender.

Around the same time that I bought the USB 2.0 extender featured previously I bought some cheap remote units for the 3022 USB 3.0 (5 Gbit/s) system.

My thought was that maybe these were identical like the USB 2.0 extender.

From the looks of it I was wrong there and will need to find a LEX to use it, but it was still interesting.

The Spectracom Epsilon Clock EC2S and similar devices are fairly high end GPS clocks/timing receivers.

I've spent a few days with one and I wrote a utility to program the device that is available for download.

I picked up a 18 year MiniDisc recorder and restored it a bit, and added some optical I/O to it.

I bricked my DCX2496 while updating the firmware, but I got it back.

I've designed a 3D printable solution for rack mounting Lucent RFTG-u receivers on cheap 2U shelves.

In the interest of public service and guarding against future failures, I pulled the EPROMs from my Wavetek/Schlumberger Stabilock 4015 Service Monitor, and Fluke 6060B RF generator.

This page has some info on the MC349 VCXO, that has been available on eBay in large quantities at low cost.

To investigate a simple way of generating local oscillators for my UHF transmitter, the CDCR83 was put on a 4 layer board and fed with frequencies from 10-150 MHz at various multiplication settings. As usual a bag of these was found on eBay and as such there was some incentive to find a use for them.

Background: a set of 110.51 MHz filters were acquired on eBay per usual, and I ended up with around 400 of them. Part number was 110E39. No data sheet was available, though a potentially related data sheet for 90 MHz filters in the same package was available from NDK. Here…
