    If you go the 98% route needless to say you need to be effing careful with it, especially when mixing with water.
    Yea I only got chemical gloves and glasses. No HEV suit...

    Happy to just get the 33%.

  2. Hmmmm Not looking great...



    Ill leave it in the dye for 15 mins and come back.

  3. Ohhhhhhhhh

    Great - glad we managed to dig to the bottom of the problem!

    good job :)

  5. Just want to check.

    1L of 33% battery acid (I have 31-38%) mixed with 3L of water for 4.5asf?

  6. Had the amazing, original idea of using one of these stone air things from fish tanks.

    Have to say, works really well.

    That'll be an air stone ;-)

    Made me smile as it reminded me of a minibus driver I had last week, who took it upon himself to act tour guide.

  9. Worked really well. The larger bubbles before sometimes caused me issues but this is great.

    Not 100% there yet. More practice and experimenting me thinks.

    Looking good.

    Can I just ask - what are you using for your cathode? (I did start setting myself up for anodizing but a squirrel ran past and I moved onto something else)
