2 fully built & Tested SSR units.
Since a friend of mine in Australia helped me do some fine tweaking on the SSR v2.0 boards, I have promised him a set of fully tested units for himself.
However, I also included the external PSU board for him fully populated too!
Thanks for your help Gareth!
Quick update, SSR v2.0 works!
Boards arrived, and I got time to build and powr one up.
Firewall is in & Running.
Yup, the new 1u front facing supermicro firewall is in and running. So quiet, but fast. I really like how I have back end management & front facing ports.
What are we running for a firewall 🙂 Untangle, yup ! Because I like it, and good at it!
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.
My F5 using IXYS Fet’s is Finished!!
Been working on this amplifier for almost 6 months now, and it is finally finished! I will post more details soon here but the just of it.
P = 26.28 Watts RMS into 8Ohm
P= 52.56 Watts RMS into 4Ohm
THD 0.03160% 1.24watts @ 8ohm
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 !
Today’s 2 Project’s Finish soldering on all the SMD Melf resistors for my Stereo All in one SSR board and do some testing. & THEN work on my Aleph Mini Class A project using 2 MeanWell SMPS powersupplies ! I have been working on this for a few weeks now and FINALY got the noise removed on the PSU’s so now I have clean ripple free 25V dc rails VERY excited because now I can work on the next stage of this project !!
SMPS units are Meanwell IRM-60-25 units.
Happy dance !
