    I found this Phone while metal detecting at the beach. It was buried about two feet deep in the sand. About half a metre below the low tide mark. Right where the shore break pounds. It had a very bulged battery too. Which I removed with a small tire lever. The back panel was not found. DSCN4665.png DSCN4657.png DSCN4662.png DSCN4661.png DSCN4664.png

    It stopped leaking water out after a few days. Can it be fixed?

    I got a new wire brush thingy for my old bench grinder. I was about a 10th of the way into removing the rust from all my tools when I started to smell a woodsmoke kind of smell. Thats when I noticed the smoke coming out everywhere.

    Devil's advocate turn....

    Your honour,

    We contend the evidence submitted also supports our contention that this witness is part of a subversive terrorism plot to expire the end-user. A ticking time bomb , if you will. The MSDS sheets indicate that although safe in their solid form, once detonated with a convenient modification turns into a explosive toxic fume generator and can become quite dangerous. We believe the unit was tampered with to promote this self destruction for another purpose.
    To reduce the global gene pool of mind numbing mobile users and those with equally mind numbing FPS type gamers.

    GHS-Classification:
    Skin corrosion/irritation Category3
    Serious eye damage/eye irritation Category2B
    Sensitisation – respiratory Category1
    Sensitisation – skin Category1
    Carcinogenicity Category1
    Hazardous to the aquatic environment – acute toxicity Category2
    Hazardous to the aquatic environment – chronic toxicity Category2

    - tongue firmly planted in cheek.
    but the MSDS data is accurate.
    Group 1: The agent (mixture) is carcinogenic to humans.

    When neighbors hear that I do electronics, I get given damaged goods to check/repair.
    These two independent repair jobs were (a): the guy had a 500W/ch amplifier rated Z minimum 4 ohms/ch. Having no concept of impedance he wanted "power" so paralleled various floor standing 4R, 8R, 16R to create only 1.1 ohms per channel! He was suprised, arguing that it is a"big amp". As seen, the output transistor fried, cooking the board, tracks, and toroid 21-0-21V transformer. He decided to rather scrap it (more spares for me) ^^. The second two (b) and (c) were due to a family's 5-year old son playing "trampoline" on their bed, landing on nearby table with AKAI dual-tape-deck.
    They also scrapped it when I showed them the extensive soldering work involved to re-join each track (cracked entire board). I plan to repair it for my own use. :)

    I have a 10" iPad that fits nicely in my back under my pant waist, but recently hard curved chairs in a fast food place proved too much and the glass cracked into a million pieces but still worked. unfortunately entire screen got replaced for 270 $cdn in 1hr
