This soldering kit contains all the parts needed to build a solar-powered night light. For this purpose, the components supplied are simply soldered together with a little solder. The circuit is already built and ready for use.

The function of the circuit:
During the day, the energy generated by the solar cell is stored in the battery and supplies a warm white LED with approx. 25 mA, which switches on automatically in the evening at dusk. Depending on the charge level of the battery, the LED lights up all night. If the rechargeable battery is largely discharged, the LED is switched off, which prevents a deep discharge of the rechargeable battery and thus significantly extends the life cycle of the rechargeable battery.

Application:
Solar garden light, solar house number light, solar night light, lighting for birdhouses and decorative objects and much more around the house and garden.

Scope of delivery:
Warm LED, rechargeable battery, battery holder, coil, solar cell, charging electronics QX5252, instructions.

Steel worm, module M0.2, inner bore 1 mm, length approx. 3.5 mm, diameter: 2.8 mm

To build angle drives, bevel gears have unbeatable advantages. In contrast to worm drives they are not inhibitory and have a better efficiency.
For use in micro model construction, we have a bevel gear with only 4.5 mm outside diameter in the program.
Be it as axle drive, for winches or individual gearbox solutions, with this gear interesting solutions can not only be found in micro-model construction.

TECHNICAL SPECIFICATIONS:

• Material: brass
• Module: 0.2
• Number of teeth: 20
• Tip / outer diameter: 4.5
• pitch circle: 4 mm
• Bore: 1.8-2 mm
• Collar: Ø 2.5mm / height: 0.8mm

The new 4 mm micromotor with robust metal gear 1: 125 offers new possibilities in the smallest space and is ideal for use in model making.
This stable and high-precision manufactured metal gear, with a ratio of 1: 125, is excellently suitable e.g. for the construction of the smallest drives for light vehicles (e.g. 1:87 and smaller) or for the operation of special functions such as windshield wiper or boat radar drives. Due to the metal design, this tiny is surprisingly stable, smooth-running and fits into the smallest models. The 2 mm output shaft is flattened, so gears or shafts can be glued on or fixed with grub screws. The maximum operating voltage of 3.7 V allows convenient connection directly to a LIPO.

TECHNICAL SPECIFICATIONS:

• Rated voltage (V) : 3
• Voltage : 0.8 to 3.7V
• Maximum current consumption (mA) : 100
• Gear ratio : 1:125        
• Speed (rpm) : 50@0.7V - 300@3V
• Length (mm) : 17
• Diameter (mm) : 4
• Axle length (mm) : 4
• Axle diameter (mm) : 2

Lithium-polymer battery with 40 mAh. This tiny battery is perfect for the smallest models or special functions. It fits easily into H0 cars and still allows acceptable driving times. But also illuminated trailers or e.g. construction site barriers of larger scales can be realised perfectly with it.
In order to achieve a smaller design, the deep discharge protection was intentionally omitted from this battery.
We recommend discharging the battery to a minimum of 2.8 volts. Then the battery must be charged with 40 - 60 mA @ 4.2 Volt. Our double charger 14500 is suitable for this.

TECHNICAL DATA:

• Nominal capacity: 40 mAh
• Dimensions: 14 x 10 x 4 mm
• Voltage: 3.7 V
• Weight: 1.05 gram
• Solder connection

This micromotor with a diameter of 6 mm and a length of 15 mm was manufactured as a 5-pole version. This reduces the speed, but at the same time the torque is increased and the motor gains significantly in power. This small micromotor is therefore particularly suitable for self-build gearboxes, e.g. for the Car-System or for radio-controlled 1:87 models. Due to its very small dimensions, the micromotor also fits into tiny models.
The output shaft has a diameter of 0.8 mm and a length of approx. 4 mm and is therefore suitable for matching gears and worms.

TECHNICAL DATA:

• Shaft diameter: 0.8 mm
• Axle length: 4 mm
• Length o. axle: 15 mm
• Cable length: 20 mm
• Voltage: 0,1 - 5,0 V
• U/m: 40000@3V +-15%
• Weight: 1,66 gram

Micro worm gear kit - For the smallest applications in the smallest models of all kinds!
With this set, a wide variety of model drives and unusual special functions can be motorised in the smallest of spaces. Due to the used module of the gear wheels in size M0.2 the single gear wheels are extremely small and therefore allow great motion functions, even in micro models.
The set contains, besides the 5-pole and for its size amazingly powerful micro motor, a steel worm, a steel axle (24 x 1mm) as well as 3 brass gears with different numbers of teeth. Depending on the speed and power requirements, the appropriate gear wheel can be installed individually. The speed can be regulated with the level of the input voltage. Control by a speed controller is possible at any time.

TECHNICAL DATA:

• Voltage range in volts 0.3- 4.8
• Motor: 17 x 7 mm (without axle), 5 poles, speed of 12000rpm(U/m) @3 Volt
• Worm: steel, diameter 2,8 mm, length 5,5 mm
• Axle: steel, 24 x 1 mm
• Gear: module M0.2, height 2 mm, material brass
• 1 x 19 teeth diameter: 3,8, gear ratio: 1:19, speed: fast  
• 1 x 26 teeth diameter: 5,2 mm, transmission ratio: 1:26, speed: medium
• 1 x 35 teeth diameter: 7.0 mm, ratios: 1:35, speed: slow

Lithium-polymer battery, 150 mAh, 5 x 20 x 20 mm

This small compact lithium-polymer battery with 150mAh and deep discharge protection is perfectly suitable for 1:87 scale articulated lorries, transporters and other small vehicles. The deep discharge protection prevents the battery from damaging deep discharge during operation. If the voltage falls below 2.5 volts, the deep discharge protection automatically disconnects the battery from the consumer. This considerably prolongs the life of the battery.

TECHNICAL DATA:

• Dimensions 20 x 20 x 5 mm (with deep discharge protection)
• Voltage : 3.7 V
• Weight : 3,75 gram
• Connection type: cable, 60 mm long
• Discharge characteristics: 2C continuous, 4C peak
• Charging current ideal: 150 mA/4.2V, or lower/4.2V

This MircoALF has been designed for all those who want to switch the indicators, driving lights, warning lights and two extra flashing beacons comfortably and in the smallest possible space (e.g. in an articulated lorry). All functions are switched via a proportional channel of the receiver. In addition, the high-quality output stages with a load capacity of up to 500mA can also switch several LEDs or other loads.
Despite the small dimensions, the solder pads are sufficiently dimensioned so that the cables can be soldered on easily.  
The LEDs to be connected must be provided with a series resistor for current limitation. However, our 3.7 Volt LEDs can always be used (such as LR-K, etc.), which already have the required resistor integrated in the cable. This way, the installation of light functions is not only reserved for professionals.

TECHNICAL SPECIFICATIONS:

• Operating voltage in V: 2.7 - 5
• Output current per output in mA: 500
• Dimensions in mm: 12 x 7.8 x 3.1
• Outputs for left and right indicator, driving light, rotating light (2 outputs alternating)
