New firewall Build !!

Just won a new mother board on ebay today. Supermicro MBD-A1SRI-2758F-O with the Atom C2758 8 core cpu. Ordered 16 gigs of DDR3 Ecc SoDimm memory for it, 2 x8 to get better channel speed. Not sure of what chassis I will end up with, maybe a Supermicro front panel 1u rack mount case & pcie – dual 10g port nic.

For now, i’ll just use a pair of 1gig nic’s on the board. I have Telus business Fibre @ home 1gig symmetrical internet.

I’ll post pictures of my build as I go. Parts have shipped, now to wait. Nice thing about SuperMicro Server boards, they have dedicated IMPI port’s so you can manage the board remotely.

Little Red Book-Shelf !

Thought I would update the blog a little, been really busy at work and some side projects to keep the hobby funds active. Had some time a few days ago to measure the Little Red Book Shelf speakers, and cobble together a very basic crossover.

I am pretty impressed with a little basic crossover, this little Sb Acoustics SB15NBAC30-8 woofer plays damn low and sounds amazing in this ported enclosure.

Stay tunes, I hope to update the crossover with better structure & some better measurements before and after.

Little Red Bookshelf Speakers

Been a while sorry guys ! Been busy working on Nelson Pass F5 Amplifiers & other Audio related things.

Thought I would post some pics of the progress on my little Red bookshelf speakers ! I did a quick inside the house Measurement the other day and “DAMN” for no crossover or any filter they are pretty smooth. ! ( will post more on that later )

For now a few photos of how they look so far ! I’m very happy with the look’s and color !

Red Book Shelf Speaker Project!

Been working on a design for the last few moths and the CNC’d pieces were finish for me this week !! Excited.

The speaker will use a Ribbon, Neox-2.0 and the 5″ driver is a Sbacoustics SB15MFC30-8 5″ woofer.

The box will be all rounded over corners & painted Chalk Paint red!

I did a project a few moths ago, and really really liked this red paint so im doing another pair of speakers with it !

SMPS & Aleph Mini Progress !

Qa401 unit, with new 18″ XPS Touchscreen tablet!

New toy ! My old Dell XPS 18″ tablet with touch screen was donated back to me ! Owner didn’t use it so, back it came.

After giving it a clean up & fresh install of Windows 10 pro & activation she was ready to go, but wait, it needed a ton of Dell Firmware updates so I did those too.

The machine is nothing special, just a basic I5 with 6 gigs ram and a 256 gig ssd.

BUT now going to be used for the test becnch since it has a nice big 18″ touchscreen.

Lenovo Server Gets Second PSU!

OH ! man it’s been a long time since I have bought anything for this Awesome Lenovo St550 server of mine. She runs my life and the whole house but I have neglected her 😦

This spring I will be taking her covers off and giving her a nice blow job !

HOWEVER ! Today I received her new “second” hot-swap psu ! Why ? well, because I have some upgrades for her planned.

Next up, “already ordered” another 64 gigs ram, bringing the total to 128gigs DDR4 2666 ECC ram.

After that “not ordered” second Xeon Silver 4210 spu.

Then, a pcie x16 16 port Raid card, currently only have a 8 port one in there.
