The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

I made a Firewall / Router for my home using some spare mini-ITX hardware, a rackmount chassis, a switch, and an install of PfSense (open source enterprise grade firewall and router software). After seeing all of the exploits found in SOHO routers recently, and the poor vendor support for secure features, as well as a general lack of advanced functionality, I went this route.
It ended up being really easy to setup, after assembling the hardware (as any standard computer), I had PfSense installed and my network up in under 10 minutes not counting all the advanced stuff I threw in like a Snort IDS and SSL certificates. I have a wildcard for one of my domains so now I have a valid SSL cert to manage this thing over the web interface, which I haven't found possible with most SOHO routers even though they are so critical to a network.
It has 4 GB RAM (overkill for most purposes, but I can even support a video stream going over a VPN to me and I offer a VPN to friends of mine on an isolated subnet), a dual-core AMD APU (since I didn't want to pay for separate graphics support, and it easily gets the job done for a low cost), the onboard gigabit NIC, and an add-on gigabit NIC.
WiFi is currently handled by a Cisco small business router on a different subnet until I get the wireless card working as an access point in the unit itself.
The switch underneath is a TrendNet gigabit switch, since I host some LAN parties and move a LOT of data over my network between my CableCard tuner (which is network based), my networked windows media center, my network storage, and every machine in general.
And yes, I managed to cram my cable modem into the unused disk drive bay :)

Aard-Wolf brought the amber to the factory where we both work some time ago, only through a great act of willpower (plus a weakness of funds) did I decide not to collect amber, truly interesting, ancient animals in near perfect detail (with an eyepiece) in your hand. I loved that I saw the big insect first, then 'discovered' a smaller one ... then another even smaller. I can definitely recommend getting a interested friend to invest so you can have a look ;)
P.S. this is a photo of the current state of my HF PA everlasting project, roughly tested but needs work, photographed by Aard-Wolf today ... nothing noteworthy but I like it. (my first hf pa .. hopefully)(I bought a few spare transistors!)

You should post some more info on this, Sulaiman. It's worthy of it's own thread in the projects section. I might even pick up some tips on HF circuit layout

Ash, there is no technique, it changed as I went along (read application notes, looking how others do stuff etc.) e.g. started with the rf power transistor, last were the two bias 'modules' and most of my future rf projects will be be mainly smd (easier than expected) - through-hole components are an endangered species (I'm just obsolescent ;) When/If it works as expected I'll write something ... things not to do probably ! Need to change the poor o/p filter of my eBay dds sig. gen., then I'll know. to keep on topic, a poor photo' of the transceiver rack

Zinc whiskers on a cable clamp around a large supply cable for a industrial machine, it have properly been forming over some 20+ years, taking machine age into account.
