    Give an Artist a box of different sized colour blocks and he will create an art work; give me the same box and I will sort it by colour and then size :)

    ..... and I'm pretty sure this thing will eventually produce some spectacular photos

    Hey Arthur , any idea where I can buy an SCR ?


    I tried a normal 100 amp 30 volt solid state relay with a security battery - it takes a while to blow so I've ordered a 3 farad capacitor
    to help it a bit .



    The best I could do with this is 1/30th sec to get the slow melt of the wire - it would be good to be able to work with safe voltages so
    hopefully I can connect the large capacitor and get some extra kick in the power output but I think it would be really good to have
    an SCR that can handle 330 volts and high current .

    Jaycar over in Frankton will have what you want

    You want to go for the fastest gate switch timing you can get even if you have to compromise the volt/amp rating a little.

    I was in jaycar this morning and the best they had was the 30 volt 100 amp solid state relay .
    I asked around and got shown a link and ordered this SCR[?] . I should have it by Monday afternoon hopefully .


    Anyway it's way past my bedtime - going to go and catch up on some sleep now
