  • Beginners Guide to 3D Printing - Anet A8 DIY 3D Printer Kit

    Just waiting for mine to arrive. Great videos! From what I've seen these printers benefit greatly from anything that increases the rigidity of the frame. I was wondering if you noticed any difference after you put your spool of PLA on top? I'm not sure of the weight of a spool, but a spool without the printed centerpiece would cause movement in the frame every time the spool 'rolls over' no?

    Well, after the Axe FX, I don't have any money left for electronic parts lol.

  • How to Make a Powerful Burning Laser for CHEAP!

    To anyone wondering.......Laser diodes are essentially led's. If you go powering them up with any old power source they will draw as much current as they want and probably just burn out - a quick flash is all you'll get then nothing.

    Lightning Detector and Counter

    I'll bet with a bit of modification this could be used to trigger the shutter of a dslr.

    Apparently some pigs are more equal than others, but I'll bet they taste the same.

    Try reducing the overvoltage control multiple turns until the fault light goes out. Mine arrived and when I powered it up to test it read 000 volts. I contacted the ebay seller who sent me this link to a docx file that I will repeat here in the broken english that it was typed in.---------------------------------------------------Battery undervoltage protection adjustment method: (12V lead-acid battery set 10V undervoltage protection, turn off the output as an example)Input voltage stabilized power supply adjust to 10V, adjust the undervoltage protection potentiometer (clockwise increases, counterclockwise decreases), until the fault indicator light (red light), which is set up successfully; so the battery discharge to 10V, will automatically cut off the power supply to protect the battery from being damaged.Note: if it is not battery powered, you can't set it up;output voltage adjustment method: input power supply (voltage is higher than the undervoltage protection value), the red light is not bright, the blue light is on, is connected to the output of the multimeter, adjust the output voltage potentiometer clockwise increase, counterclockwise),until the required voltageNote: normally the red light is not on, the blue light is on, otherwise, for the fault, the input is under voltage protection, the output over-current protection, the output short-circuit protection, please remove the trouble and re power.output current adjustment method: (12V input 12V charging battery, charge current 5A as an example)Input connect the 12V power supply, output and connect the ammeter (red pen connected to the output is positive, black pen then negative, direct short-circuit output. Recommended with more than 15A ammeter, to prevent burning insurance), adjust the constant current potentiometer (clockwise, Hour to reduce), until the ammeter shows the required value of 5A, remove the ammeter, connected to the battery can be normal charge.Note: If used for constant voltage equipment, only need to set the maximum output current.

    Does anyone have any idea why I have no current adjustment? It shows the draw but I cannot adjust it with the pot, even when under a load. :(
