EEVblog #1334 – Mystery Dumpster Teardown

Mystery dumpster teardown time! With the most amazing mechanical mains power switch you’ll ever see! ...


  1. nice !

    A friend of mine records his guitar compositions in his living room.
    Only a laptop with an H1/H2 is needed as the “studio”.

    Interesting how cheap such a product can be manufactured and sold, supposing that the owner still earns some money from.
    Even weird that quality parts from TI are used instead of low priced taiwan stuff.

    Can you rebuilt the H1 to a functional unit ?
    Did you ever fucked up disassembled gadget ?

    Keep on with these excellent videos…


  2. As always, awesome review. What made me cringe though, was ‘WAV’ lol. Which is the windows 8.3 abbreviation for ‘wave’ and thus should be pronounced as wave! Other then that. Great great review. I love teardown tuesdays!

    • WAV = “wahhvvv”
      MP3 = “mip3”
      MP4 = “mip4”
      AVI = “ah-vee”
      OGG = “awg” (like dog)
      FLV = “flav” (or sometimes “filv”)
      WMA = “woomaa”
      MPG = “mpeg”

      I’m sure there’s more and other ways to say them…

      It’s fun to pronounce these in silly ways, especially when it riles up the coworkers 🙂

  3. Most of the time I don’t know what your talking about (over my head)but I check every day for something new thanks……

  4. Pretty cool teardown… I feel your pain in having to de-solder something to get access to the circuit – always scared to destroy something during reassembly.
    Although the DSP uses very little power (for a DSP), it got me wondering how is the battery life for all this horsepower on such small recorder.

  5. I really like tear down Tuesdays. The retro equipment reminds me of how much designs have changed over the past 30 years. The new stuff keeps me thinking and learning. Good Job Dave!

  6. Cool device. I like it too. The layout engineer must have been bummed-out in the end to have to run that fat black external jumper across the board. But otherwise, a nicely realized product.

    Will that device work as a USB “sound card” that is powered by the USB port (no battery installed)? Can it “stream” encoded MP3 in real time to a PC throgh the USB port?

  7. Do we get “stick up” video? (is “stick up” the opposite of “tear down”?)

    Or do we have to run this video backwards?

  8. thanks for sharing this post. very useful one.

  9. I have one of these, its a great little recorder, the sound quality is very good.

  10. Hi there to every single one, it’s really a pleasant for meto pay a visit this site, it contains helpful Information.
