Makerspace Solder Kit
The Makerspace Solder Kit is a really simple soldering project kit. It’s an ideal gift for anyone learning to solder or wanting to practice their soldering skills.
The kit consists of:-
- Circuit board
- Coin cell holder
- Coin cell
- 2 colour changing LEDs
- Mini lanyard
Preparing the board
The first step in soldering this project is to melt some solder onto the 3 large solder pads on the reverse side of the circuit board. A thin layer of solder on the battery pad will help provide better contact to the battery, and a small amount of solder on the 2 smaller pads will help when soldering the coin cell holder.
Soldering the Coin Cell Holder
The next step is to solder the coin cell holder in place. To do this, place the coin cell holder onto the circuit board so that the 2 side tags line up with the small square solder pads. Ensure that the opening of the coin cell holder is facing away from the 6 small round solder pads at the top of the board, otherwise it will be difficult to insert the coin cell. It’s also a good idea to place a small weight onto the coin cell holder to keep it in place while it is being soldered. To solder the coin cell holder to the circuit board, hold the tip of the soldering iron onto one of the tags, and apply a little more solder so that it melts over the tag. Once the first tag has cooled, this should be repeated with the second solder tag.
Soldering the other components
Once the coin cell holder is soldered, the next step is to solder the components on the front of the circuit board. It doesn’t matter too much which order this is done, but it’s probably easiest to solder the resistor first.
To solder the resistor, bend the resistor wires down at an angle of about 90 degrees, and push them through the circuit board from the front where the R1 symbol is. Note that it doesn’t matter which way round the resistor is soldered. Having pushed the resistor wires through the board, the resistor can be held in place by bending the wires slightly, and also placing the board face down on your work surface. Finally solder the resistor by applying the tip of the soldering iron and melting a small amount of solder to each of the 2 resistor wires where they meet the solder pads.
The switch should probably be soldered next. As with the resistor, this can actually be soldered either way round. The 3 pins of the switch need to be pushed through the board from the front, and then held in place while they are soldered. The easiest way to hold the switch in place is probably to simply lay the board on your work surface, and the weight of the board laying on the switch should be enough to keep it in place while it is soldered. To solder the switch, apply the tip of the soldering iron and melt a small amount of solder onto each of the 3 pins and switch solder pads.
The last components to solder are the LEDs. It is important that the pins of the LEDs are pushed through the correct holes. The longer of the LED pins is the positive terminal, so needs to be pushed through the hole marked with the + symbol. Push both LEDs onto the board, then place the board face down again on the work surface and solder them in the same way as the resistor and switch.
Finally, slide the coin cell into the coin cell holder (ensuring that the positive coin cell terminal is in contact with the positive terminal of the holder). If the LEDs don’t light up, slide the switch to the on position and revel in your creative success.
