History of DIY audio
Audio DIY came to prominence in the 50s to 60s, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.
While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest. DIY is especially active in loudspeaker and in tube amplification. Both are relatively simple to design and fabricate without access to sophisticated industrial equipment. Both enable the builder to pick and choose between various available parts, on matters of price as well as quality, allow for extensive experimentation, and offer the chance to use exotic or highly labor-intensive solutions, which would be expensive for a manufacturer to implement, but only require personal labor by the DIYer, which is a source of satisfaction to them.

A 0th-level attack at designing a direct conversion AM radio receiver. "Direct conversion" means we use a mixer (which just multiplies two signals) to downshift the radio frequency signal to baseband (audio) frequencies. I still don't really know how to couple the antenna into the circuit, how to use a crystal oscillator or a mixer chip, or lots of other things.

How did the owner of this archaic radar station persuade Hippo Hardware to take it off his hands? Could it be that he had some especially tasty architectural fragments or coveted hardware?
Anyway, it's there now.
It's too modern to lend itself to a Steampunk project. The most obvious reuse would take advantage of the goggle-like viewing station for displaying visual art of some kind. The knobs, switches and buttons would allow the viewer to modify the image or change the content. The art would need to be pretty darn compelling to justify the time and expense of converting the device.
A cheaper alternative would be to place a visual art object inside the hood. The controls would adjust the lighting. The problem is that unless there were multiple stations that each offered a different experience the impact on the viewer would be minimal.
This is probably much like the decision tree others have conjured when contemplating what they could do with this contraption.
Let's just call it a white hippo and be done with it.
----------------------------------------------------------------------------
Hippo Hardware is an eclectic building salvage store specializing in hardware, lighting, architecture and plumbing from 1860-1960. We offer assorted collectibles, trinkets, whatnots, and whoziwhatsits depending on what we get in. The spirit of Hippo Hardware is to rejoice in the individual, the unique, and the original.
Hippo Hardware was officially established in 1976 after the founders Steven Miller and Stephen Oppenheim decided to turn a life of swashbuckling adventures into a second life of swashbuckling adventures. We live in the local, even for our customers far away. That means you will probably hear a story about burying a Porsche in a state park while you are asking about a faucet or see photos of our cashier's Saint Bernards while you're paying for a light fixture. We strongly support community projects, teachers, artists, adventurers, dreamers, and one-man-bands.
If you're looking for a hard to find hardware pattern or can't find the match to your lamp shade, we'd be happy to tell you if we have it, seen it, or know where you could get it.
To make sure you get what you need, we offer the following services:
Customizing - We do our best to make sure it looks just right. Our lighting shop can customize length, finishes, plating, and configuration. Our plumbing department will coordinate refinishing with local companies. The hardware department is able to darken, refinish, clean, and rebuild. Our services can vary depending on staff so please contact us with your project details.
Conveniently browse our online section of items! Please note: our online section is much smaller than our store selection, we do offer returns for online purchases but do not refund original shipping or provide return shipping. We ship on Wednesdays, Thursdays and Fridays.
Trade in - Bring in what you have and we will offer you in store credit or cash. Email pictures first if you'd like to talk about it before you get here.
Mortise lock repair - Hippo is the only hardware store in Portland that offers full mortise lock repair--including French Door mortises and closet mortises! Our repair shop can diagnose and repair your mortise lock or perhaps we have a replacement if a repair is not an option. Shop prices are $80/hour. Please call our store and ask for Colin to speak about your repair!
Hippo Hardware has three glorious floors and 30,000 sq feet of building salvage to explore. Our inventory, and staff, is divided into four departments: Hardware, Lighting, Plumbing, and Architecture. We do our best to highlight our inventory full of unique items and reproductions on our website, but most of our stock is not online yet. Please contact us if you're looking for something you don't see here.
We donate to: NARAL, Planned Parenthood, Portland Women's Crisis Line, Benson High School, Sunnyside Environmental School, Junk to Funk Recycled Fashion Show, SE Works, Vision Northwest, Multnomah Playschool, Union Gospel Mission, Community House, The Friendly House, Marylhurst Childhood Center, Portland Lions Club, Sabin Elementary School, Oya No Kai supporting the Japanese Magnet Program, Lee Owen Stone Preschool, Public Interest Law Project, Jefferson High School for the Performing Arts Theater Department, imago Theater, Reynolds High School, David Douglas High School, and Milagro Theater.
