  • This is not usable for reflowing LEDs, I've wasted dozens of em trying to use this as a substitute for paste. Also appear to be quite a bit harder to remove excess from PCBs.

  • Provided the circuit can handle it. One should be able to do bracing and jewelry work with it, seems almost too good to be true.

  • Tried to use this to hard solder some stuff, not enough heat, not even able to melt 1mm aluminium 5% mg mig wire with it. Will attempt to overdrive it with 36V to see if it gives the extra oomf it probably need. If not I'll have to build a spot welder instead.

  • When will this be in stock again? It's like a fundamental part of the hobbyist/DIY arsenal.

  • werd. Ninja edited that zener to a diode without saying early on.

  • Seems the basic resistors wasn't enough to amplify the pickup output of my acoustic guitar to another transducer placed on the inside of it. Basically planning to use it as a budget amp run on battery.

    EDIT: works much better with two 5.1k resistors. But the 1W transducer I had was a bit to small. But it gave the reverb-echo-effect I was looking for. Great circuit!

    EDIT2: After some evaluation I can't say I notice any real difference. It works when plugged in to a computer. But I barely get any effect using a pickup. Thinking I might need a preamp for the pickup.

    EDIT3: Duh. Just realized I've been driving it with 2x AAA which lands me at 2.4V. facepalm

  • Are these dishwasher safe?

  • Gnnh. I needed one that goes past 1700C for accurate temp measurement for melting titanium.

  • I imagine that green laser could be fun using with this. Adds a little more control of the beam so to say.

  • These have a perfect size for RPi and perm protoboards as well.

No public wish lists :(
