Can two students use one electronics kit during Supercharged Science live classes?

Parents often ask if two students can use the same electronics kit.

Ideally each child should have their own, unique kit.

Here are more details:

Regarding the electronics kit:

The Electronics Essentials kit is designed for one student. While there are enough parts for two students to build the small projects that occur early in the year, there will only be enough parts for one student as we get into more detailed circuits.

However, all the parts in the Electronics Essentials kit are reusable. If you buy a single kit, one child could build the circuit, get it working, and take it apart….then the other child could build the circuit by watching the recording.

But, if you want both kids to build projects during the live class, you’ll need two kits.

Regarding the parts boxes:

By the way, I highly recommend that you purchase the two parts boxes either together with your kit order or directly from Harbor Freight.

If you do buy two full Electronics Essentials kits, other parents have reported that they can fit two full sets of parts into one pair of boxes.

Regarding the digital multimeter:

You will need at least one digital multimeter for use during the class. You can either add one to your order or purchase a meter from other sources. By the way, parents find that two students can share one digital multimeter.

Regarding the Soldering Basics Kit:

You’ll notice that we offer a Soldering Basics Kit. This kit used during pre-recorded lessons on electronics soldering and is not needed for the live classes. (The soldering lessons are available under Unit 25).

Soldering is a process that permanent attaches the electronic parts onto a circuit board. So, if you would like your kids to learn soldering, they will each need their own soldering kit.

Please note that some additional soldering tools are required. You can find more information on those parts here: https://www.fvresearch.com/soldering-tools/

Recommended Tools for Soldering and De-Soldering

Soldering is an essential skill when working with electronics. But, it is important to use the right tools so that your circuit will work reliably.
(A properly designed and soldered circuit can last for decades).

I understand that investing in tools can get expensive.
So, I’ve assembled a list of items that are reasonably priced for students and hobbyists, while still being reliable.

Please contact me if you have any questions.

“Bare-minimum” tools

Soldering Iron – Click to order from Amazon

You will want a pencil style soldering iron of 25-30 watts. Never use a soldering gun on circuit boards!
I recommend a soldering iron station that allows you to adjust the temperature.
Your soldering iron tip should be a point or a very thin (1/8″) screwdriver tip.

I recommend the Weller “5 to 30 Variable Wattage Precision Grip Soldering Iron Station” Part Number: WLSK3012A

Notes:
Never rest your iron on a table. Always use holder or bracket designed for soldering irons.
You’ll need a wet sponge (included with the station I recommend) or brass sponge to clean the tip of your iron.

60/40 rosin core solder

Solder – Click to order from Amazon

I recommend using 60/40 rosin core solder. This solder is an alloy made of 60% tin and 40% lead.
Rosin is a substance that helps clean the soldered connections and helps the melted solder to flow more easily.

Note:
Always wash your hands with soap and water after working with 60/40 solder.

Holder Option 1: Circuit Board Holder – Click to order from Amazon

Never use your hands to hold a circuit board or parts while you solder. The burn risk is just too high!

I recommend using this circuit board holder. You can insert your parts and then rotate to the other side to solder your connections.

 

Helping Hands Soldering Aid

Holder Option 2: Helping Hands Soldering Aid – Click to order from Amazon

Helping hands are an alternative to a dedicated circuit board holder. You can use the two alligator clip “hands” to hold a circuit board. However, you’ll need to reposition the circuit board to solder your connections.

Note:
Always put masking tape between the alligator clips and your circuit board. Otherwise they can damage the board and the delicate circuit traces.

Flush Wire Cutters

Wire cutters – Click to order from Amazon

You’ll need diagonal wire cutters to trim the leads of your parts once they are soldered.

I recommend flush cutters such as the ones shown on the left.

Long-Nose / Flat Nose Pliers – Click to order from Amazon

Pliers such as these are useful for forming parts and during the de-soldering process.

I recommend long-nose / flat-nose pliers with serrated jaws such as the ones shown on the left.

Additional useful tools

Brass sponge – Click to order from Amazon

When it comes to keeping the tip of your iron clean, a brass sponge, such as the one shown on the left, is a better alternative to the wet sponge.

Brass sponges do a better job of removing material and they don’t cause dramatic temperature drops like wet sponges do.

Tip tinner – Click to order from Amazon

Tip tinner helps remove baked on residue from your tip and it helps prevent oxidation from accumulating.

De-Soldering Option 1: De-Soldering pump – Click to order from Amazon

De-soldering pumps are used to “vacuum” molten solder. They come in handy for removing excess solder from a connection or for removing a soldered part from a circuit board.

The de-soldering pump I recommend has a larger plunger for a stronger “vacuum” effect. I find that this pump is more effective than de-soldering wick.

De-Soldering Option 2: De-Soldering wick – Click to order from Amazon

De-soldering wick (also known as de-soldering braid) is another method for removing solder from circuit boards.
