  • Ohms Law for Dummies

    Is there an equation for solving what size a capacitor is needed within a circuit?How do these equations help in a practical way?I'm currently trying to understand how I can even make use of this knowledge if at all.

  • DIY SMD REWORK STATION.

    I have a soldering station and I don't have fan control due to a short I Mangned to find the object that caused the short but I still don't have fan control I was thinking about bypassing the PCB. I can't find a schematic for this station so my thought is what if I could figure out the wires that control the fan pull them and solder them directly to the potentiometer giving me back fan control.I can find the wires that control the fan by opeoing the handle but the potentiometer has 3 terminals so I'm unsure how to do the bypass could anyone lend me some lknowledge on how I can do this bypass?

  • Bottom Bracket Overhaul (bicycle Maintenance)

    I have a 7-speed Cruiser and am having trouble finding any instructions on how to do maintenance on it because it's different than a mountain bike and I have never had a bike like this and spring is here and summer is coming. I need and want to clean and grease it before then so if anyone knows of where I can find some pointers for doing maintence on the cruiser I'd be very gratefull.

  • Convert an ATX Power Supply Into a Regular DC Power Supply!

    Is there any way to get a higher voltage out? I would love to get 24 and higher.How do you determine which bundles connect to which rail? Could a potentiometer, mini multimeter and an ammeter be added without too much more effort?

  • DIY Soldering Station for HAKKO 907

    I have been looking at doing the Hakko T12 soldering iron and station but there doesn't appear to be a full kit they come in a variety of kits. Would anyone know what kits you would need to buy in order to get the complete unit?

  • Soldering tiny SMD components the easy and fast way (with a hotplate)

    I was unable to find a hotplate so I Came up with my own technique to solder small parts and since I don't have 3 hands I used the device with the magnifying glass that the call a 3rd hand to solder the tiny resistors on a PCB. I used the alligator clip to hold the solder I then positioned it over the pad that I needed to solder and once one side is soldered in then it's easy to straighten and solder the other side, I used a rotary tool to grind a tip down to a very fine point as well and of course antistatic tweezers. It took me a fairly long time to figure this out and this is how I found this article in the 1st place, I didn't have the needed items and that's when this idea came to me. The 1st thought I had was to try and get something to hold the iron kinda like a spot welder but it...

The 1st thought I had was to try and get something to hold the iron kinda like a spot welder but it wouldn't have worked, there is another way as well you can drop a bit of solder on one of the pads then you use the tweezers to hold the part heat the solder and position the chip in place this works fairly well but you have to have a small tip. Note: if you do try using what I refer to as teh presoldered pad only do it on one side and don't put too much solder on the pad all you want is enough to tack it down then solder the other side and add more solder to the pre-soldered pad if necessary. if you put too much solder on the pre-soldered pad it will make placing the chip or resistor straight and flat against the pcb
