Do you have a webpage or a thread that shows examples (pictures, preferably) of any of your work? I've heard you talk about it for what is probably years now and I'm really curious to see the kinds of stuff you've come up with. Especially a project with these Lambdas!
Electronics is a hobby since the late 1970's and I got into
audio in the early 1980's. In mid to late 90's I took a break from
this to do other hobbies. Electronics and audio can get boring too!

Electronics & audio, the first thing I did was to satisfy my curiosity,
to learn everything I can about it, personal quest. The last thing on
my mind was predicting the internet revolution and how I should
have taken pictures and documented my projects as nobody would
believe me today. ... lol ...

Most of these hobbies are just hobbies, messing around
with stuff in the garage, educating myself. But my main job is
connected to the electronics industry so I have to deal with that on
a daily basis, but it's not audio related.

I do have ancient pics of one of my bigger electronics projects that
I tried to take beyond a curiosity. My Voice Blaster project,
a product similar to the 'Invisi-Beam', a car audio voice
alarm with microwave sensor sold on the market. You walk next to
the car and the car would talk using a pre-recorded voice message
that the user can't change.

My idea was to use a new chip on the market to allow the user to
program their own message in non-volatile memory, a very interesting integrated circuit in the early 1990's.

PCB for the project;

Final product;

Another recent project that I wanted to take beyond curiosity is a
DIY home amp project. The base amplifier circuit design was created
by Anthony Holton as it was his design and I liked it alot, no need
to re-invent the wheel. I wanted extra "stuff' in the amplifier
package and these extra circuits were implemented on the
circuit board design. I also created a 'rail detector', a certain
protection circuit that triggers on a specific failure event. Long story
short, it was just cheaper to buy used pro audio amps than
to invest big money on this project and try to make it look
like a professional product. I just don't have that kind of money.
I did compete my documentation package and did the PCB layout,
but no prototype was built.

Documentation;
On my hard drive as a Word file.

From the electronics side, I showed you something ancient
and something new.

From the audio side, I have prints of installs I did for people
but this is ancient news. Y2k and beyond I'm doing whatever
I want, that amp project was the bigger project from the electronics
side, the loudspeaker project was more or less saving up money
to buy certain drivers for a crazy project, a project that consumes
the most money of all my projects ever. It will take time to mature
before I hear the reward.

In the meantime, people are asking me about line arrays
on another forum and I keep giving out the same answers, so
recently I just started this thread so I can just point those people
there and we can talk about it and share information.

In that thread, I linked my budget line array project and related
topics for reference. It can give a noob a starting point for a
project like this.

Try to have fun with your hobbies.

FYI, if you use an Art Cleanbox with your proamps like many
do to drive subwoofers, then check out this thread.

A simple mod costing cents can save the day.

I mostly spend my time on this forum, it's a new forum section.

Colour change time to save sanity. The silver metallic was starting to very faintly highlight the joints on the laminations. A flat colour doesn't do that since the basecoat isn't light reactive.

I've gone for the Ferrari Rosso Corsa, which is a mind numbingly intense shade of red. I absolutely adore it, although I seem to be the only one from the couple of people who've taken a look and commented. The silver is definitely more classy but this just looks intense and plays off the gloss black superbly.

I've also switched over to water based finishes and I have to say they have come along so much. Quite expensive at 63 for 1.5ltrs but it dries in minutes, seems tougher then celly finishes and the gloss is high.

I wouldve stayed with the silver
The red screams too much attention to the speakers, I'd be way too distracted when listening to them. Great for showcase though.

Speakers like that deserve to be red. I like it.

Yep the silver has classy look to it although I would prefer if it was a little less bright silver and more titanium.

Sadly, for me, using any metallic on these baffles is just going to drive me nuts because from certain angles you can see a slight change in the metallic where the light interacting with the surface is highlighting the surface imperfections on the basecoat. You don't get any of that with flat colours.

I've also bought another Ferarri colour, Grigio Titanio which is a dark silvery grey. I look forward to using this on another project where things aren't so critical.

Nice, I wonder what your female friends would think. The might actually love it, my ex wanted pink speakers
Shin, you mentioned water based. Do you mean acrylic? Thats what I've been using. Seems to require quite a few coats, and you're right about the price!!

I'm not usually into "techno-modern" looking speakers or anything that looks like a car, but that red really looks excellent on those speakers! I approve of the change!

BTW do you use any treatment on the MDF edges to keep seams from showing? I use Minwax Wood Hardener but my projects so far have been veenered so it didn't really matter. But I have a future project that will be all piano black and i was wondering if there was a good way to prevent swelling and the seams becoming visible.

Acrylic and waterbased are different animals. Waterbased you could drink and still live although you wouldn't feel too great, if you drank acrylic you'd be less than talkative. Permanently.

Waterbased is pretty safe but up until the last couple of years its been very much a no go for decent paint performance the automotive industry requires. Today, good waterbased paints cost about 3 times more than good 1k or 2k paints but you don't have worry about using an airfed mask nor looking like Gordon Freeman with the a hazard suit. The performance of the products I'm using is better than 1k but still behind 2k.
