  • Shine a Little Light on That!
    It seemed like such an easy thing to fix. The bulb on Bill Lewis's flashlight needed replacement. A lot of people would probably just toss the flashlight in the trash and get another. You can pick up a new one pretty cheap. But Bill wasn't ready to do that just yet. “The flashlight is nothing … Read more
  • Big Sounds from Small Pieces at Bargain Prices
    Everyone is familiar with that old saying: bigger bang for your buck. And Jason Sunderland is a man who practices that mantra by using legacy electronics at bargain prices to bring big sounds to his guitar. Sunderland is an electrician by trade who is turning his skills and hunger for knowledge into practical applications. Using … Read more
  • The Mouse that Roared
    It's just an ordinary mouse. They're everywhere — the pantry, the garage, or the warehouse — and yes, even at ObtainSurplus. You see droppings first, or maybe a blur of fur skittering into a crack so small that physics seems to deny passage to anything but a dust mite. Most of us would pull out … Read more
  • “Used is great for me -“
    An AVO Surge Tester with all the bells and whistles In a “throw-away” society where we often think the newest is the best, Matthew Goettemoeller stands tall. He likes used — and not just because it's cheaper. Case in point: a surge tester. Specifically an AVO Multi-Amp DS-13SA Surger Premiere. That's the long name for … Read more
  • 5,214 Miles & Seven Days
    Somewhere in the cargo hold of a UPS jet in mid-April is a small but very important package of surplus industrial equipment with a five-figure price tag. It has a long journey from its starting place in Boise, Idaho to a small village — Saint-Paul-Lès Dax — in the south of France. That's a distance … Read more
  • The Gauge and Snoopy
    It's not often one shares their thoughts about an industrial gauge and a cartoon dog in the same sentence, but this one is too much to pass up. This is about Zachary “Zac” Fisher, a fascination with anything NASA, a cartoon dog, and an industrial gauge. It starts with this instrument: Idaho Surplus Auctions … Read more
  • Vidal Sassoon Goes Industrial?
    It's a sure bet that Mr. Sassoon didn't have anything but styling in mind when he began selling hair dryers decades ago. He passed away several years back, but he would probably appreciate Obtainium's innovation and sense of creativity. Credit goes to this guy—Dan Matthews. Dan came up with a quick, efficient way to test … Read more
  • When Legacy is Way Cool
    When this piece of legacy electronics first showed up at the Obtainium warehouse thoughts drifted back to my old radio days—the big boards with dials (attenuators) and meters that measured levels to make sure your voice wasn't over-modulating, but a closer look put an end to my nostalgia. It was something equally or perhaps more … Read more
  • Little Things Mean a Lot
    Close your eyes and think INDUSTRY. Can you see it now? That big smoke stack over there—massive machines, warehouses surrounded by railroad tracks. We're talking big boy stuff. Dirty faces and overalls. Alright, alright, that's a little old because things have changed. Just ask this woman. This is Ginny Root. She is the master and … Read more
  • MAD MAX? No way….
    Nope. This is happy Max Porter. A ray of sunlight in the world of customer service done right. This is the invoice Max sent to John, the guy who owns Obtainium, who bought a battery one day and got it the next day. It was packaged neatly, the invoice in a plastic pouch and the … Read more
  • The Ultimate Shiner
    And why such a little fish is so important I already know what you're going to ask: what the heck does a shiner have to do with Obtainium or better yet: is Obtainium branching out as a bait store? Really? Nope. But one of our customers has—Shiner Sam (, AKA: Sam Dispraseuth. Fifteen years ago, … Read more
