Copper tape can be an interesting addition to your maker toolbox. The tape itself is made of thin pure copper so it's extremely flexible and can take on nearly any shape. You can solder to it, and the tape itself can carry current just like a normal wire. On the back is an electrically conductive adhesive. The adhesive can't carry significant current, but it is very handy for sensing applications where you don't want to solder the copper tape.
We've seen such tape used for EMI shielding, working with EL, making capacitive touch pads, ultra-thin wiring needs, etc.
It comes in a roll 25 meters long, and this tape is 5mm wide and .07mm thick. The tape has conductive adhesive on one side and a protective paper backing over the adhesive.
This is an example of a circuit made of Copper Foil Tape connected to the LED:
- Conductive Copper Tape
- Tape width: 5mm
- Tape Length: 25 meters
- Tape thickness: 0.07mm
- Adhesive on one side

Simple ON and OFF switch. This is a panel-mount SPDT (single pole double throw) toggle switch.
This 3 pins toggle switch is great for any project where you have two options to select between. Maybe you'll be selecting between two voltages? Two audio outputs? Two sensor inputs? It's up to you! It's short, sweet, blue, and to the point! The part is marked at 3A 250VAC and 6A 125VAC but we haven't tested it at such high current/voltages and don't recommend it for more than 2A at 24V.
- SPDT 3 Terminal ON-ON 2 - Position Latching Toggle Switch.
- Each switch is assembled with two hex nuts, a flat and a locking washer.
- Easy installation, fits into any 6mm hole.
- Stated Electrical Spec: 3A 250VAC or 6A 125VAC, but we recommend using it at 2A at 24V
Relays are always good to have especially for electronics projects. The relay itself offers two main benefits:
- Isolation of low voltage system against high voltage system, example 5VDC and 240VAC
- Allow electronics with low voltage to control high power load, for example from Arduino to AC light bulb.
This is not an ordinary Relay breakout. It comes with 1 (single) channel 3.3V activation relay, ready to control 250VAC at 10A. Extra isolation with optocoupler at the front of control and the activation logic for the relay is configurable via a mini jumper. In simple words, the relay can be configured as 3.3V(High) activation or 0V(Low) activation. This is the universal Relay breakout board and we like it.
It comes with three (3) screw terminals for the relay output:
NO (Normally Opened),
NC (Normally Closed),
COM (Common),
and screw terminals for the control signal from a microcontroller such as Arduino or micro:bit. The control signal is optoisolated, protected. It even comes with power and activation indicator LEDs for the relay. Easy to use and suitable for beginners, and of course students too.
Input power and signal:
- DC+ = +3.3VDC
- DC- = GND (Ground or 0V)
- In1 = Control signal, 3.3V as logic High; 0V as logic Low
If you need to control AC or high current, high voltage load, this will be the perfect board.
Note: We notice the DC+ and DC- need to be 3.3V and the In1 (control signal) needs to be 3.3V or Ground to make it works properly.
- 3.3V One (single) channel relay module
- Configurable Activation Logic, High or Low, via mini jumper
- Maximum Current Rating: 10A
- Maximum Voltage Rating: AC 250V
- Can control various appliances with large current and high voltage
- Can be controlled directly by 3.3V microcontrollers such as Arduino, micro:bit.
- Build-in an Opto-Isolator for extra isolation and protection to the controller.
- A power indicator LED, and another relay activation indicator LED
Warning
Exercise proper caution when connecting mains driven equipment or appliances to relay module as lethal current will be present.
