Desoldering wick is a very practical tool for every workshop. It’s a braided copper wire, soaked in flux, so it catches solder effectively. If you have a spot from which you need to remove the solder, this strip will do a great job. Unlike the discharge pump, this strip can completely remove the solder from a hole or a pad. 1.5m should last long since you spend only one or two centimeters per one desoldering.

• Lenght: 1.5m
• Width: 1.9mm

Isopropyl alcohol is an alcohol of high purity which can be found in almost every workshop. It is useful for cleaning printed circuit boards, because it evaporates quickly and allows the removal of greasy deposits (such as traces of flux/paste) and dirt. It is also used in 3D printer cleaners and all other applications where cleanliness is important. NOTE: it also has antibacterial properties.

MG995 is a powerful servo motor that is capable of spinning and controlling things that a small hobby servo motor could never accomplish doing. It comes with a bunch of accessories so you could connect it easily with the outer world, and it’s being controlled like every other servo motor, via PWM.

This lithium-ion battery is small, light and durable. Through standard JST 2mm female connector, it will yield 3.7V which will supply your projects for a whole day (and night!). Furthermore, the battery has an implemented protection system, which prevents high voltages ( prevents over-charging), undervoltage and short circuit. That way it protects the battery, increases its lifetime and protects you from possible accidents!

This small battery is practical for smartwatch projects or other projects where battery dimensions are crucial.

• Nominal voltage: 3.7V
• Capacity: 40mAh, 0.15Wh
• Dimensions: 24 x 8.5 x 3.5mm
• Standard JST-PH-2mm connector

DISCLAIMER: This battery has to be charged with a special charged that uses CC/CV principle. Li-ion batteries are dangerous! Read our tutorial (link in the top right corner) before use.

• Frequency: 32.768kHz
• Crystal

KW12-3 is a standard microswitch – it’s activated by the external force on the lever. Releasing the force we deactivate it. This system is very quick and practical, it allows dynamic changes in the switch. The lever itself is able to rotate – it has a little wheel on the top. Microswitches like these are used in PC mouses, automobile industry, communication devices, microwave oven doors etc.

For the purpose of automation in working with plants, there is an electronic valve for the water (or other liquid?). If you need a way to control some fluid using a microcontroller, here it is! It is actually the electronic solenoid which when activated, the fluid passes through his pipe, and if not – will not. Accepts pipe diameter of1/2 and at the inlet has a filter for all the unwanted particles.

It does not contain the pump or even some additional electronics, so make sure to have an external pump or use faucet water with pressure which is large enough. Systems that have a reservoir at a higher altitude than the valve, or to be exact, that apply the principle of hydrostatic pressure will not work because the pressure will not be large enough.

• Voltage: 12V DC
• For pipes with a diameter of 1 / 2inch

• Dimensions: 78 x 60 mm

Electromagnetic lock allows you to lock the door by a microcontroller or an external system. This one can hold up to 60kg with its electromagnet, which is just enough to when used with doors of the appropriate weight. Ideally, it should be used on smaller doors, windows and drawers. It is activated, that is “locked” when it is supplied current.

It consists of two parts, piece of an electromagnet and the metal. Comes with all necessary screws for installation.

These magnetic door switch sensors are already seen, if not – then in old movies for sure where they were used as anti-theft devices, ie. alarm systems. In fact, it is a magnet and the reed switch inside a pair. When they are close to each other (recommended 13mm or less), reed switch closes. Connect it to Croduino / Arduino as an ordinary switch use the detection of open doors, windows, drawers, cupboards etc.

• Voltage: max. 200V, best used 5V Croduino/Arduino
• Max reed power: 100mA
• Max detection distance: 15mm, 13mm recommended
• Dimensions: 29 x 14 x 9mm
• Cable length: 30cm

The Raspberry Pi cable provides direct connectivity to the Raspberry GPIO port and then easily accesses all plug-ins or adapters.

thermocouple sensor is a temperature measuring device, with its range usually bigger than standard sensors. If you’ve ever bought a multimeter and got some kind of temperature sensor, that is the thermocouple.
