LED light kit parts water cycle lights DIY electronics soldering electronic production practice with battery box | Электронные

Pure hardware circuit, there is no control, no need to program the program

Note : Kit $ package itself without the jumper , jumper cut down by the resistance of the feet

Note :ElectricityNot ironTimeWith $ Devices contact , the longer the contact time , the damage , the greater the opportunity $ device .

Careful+Patient+=Success

Light-emitting diodes, the positive long-legged , short legs negative

Electrolytic capacitors, the positive long-legged , short legs negative , the circuit board has a shaded negative capacitance

Checklist: a circuit board , red yellow and green light-emitting tube all four , 12K resistor 3 , 470 ohm 3

Note : The battery housing quality in general , without switch , because the reason for the difference in assessment do not shoot

Students welding requirements : simple, easy , practical, fun, easy to use so long as multimeter , soldering iron . No Weld,

Will determine the resistor , capacitor positive and negative , positive and negative light tube , transistor direction , you can assemble a 100% success

Q:A few days can arrive ?
\u0026 np; \u0026 np;Answer:The first city in general2Days to most other regions in general2-4Days of arrival , a few areas3-7Days arrive , usually large cities faster, faster coast , northeast, northwest and slower in remote areas . Specific arrival time by the courier company control, we can not . Recommends urgent quest for customers to purchase in advance or SF Express ( SF Express to pay all shipping costs ) .
3 .Can develop ticket?
\u0026 np; \u0026 np;\u0026 np;Answer:Tickets can be developed , subject to5%Since invoices nervous goods to more than 300 $ or more to open ; excluding taxes and fees online quote . Billing rise , amount, name and other information, please leave a message in the comments box .

4 .There item? Whether to provide technical services ?
\u0026 np;A: The basic description of where we have information on or in-kind shooting chart ,After all, we are providingDIYWorkpiece material , not a training school , our customer service can not provide technical services, please understand! DIYKit parts does not provide technical support , do not understand that shot , refused inPoor!
5 .Can I return ?
\u0026 np; \u0026 np;A: Yes, the non- return of our product quality problems , buyers need to bear the freight . Meanwhile reminder: Kit assembly risks, requires a certain ability and an inquisitive mind , a problem first be resolved , we have no obligation to provide technical services in principle , but we try to improve the relevant information, all suites are personally verified detection , no quality problems.

Special Considerations:
1 .Sort of spare parts of $ more, if there is an individual package which I left $ parts , understanding what buyers want , not because of a small capacitance small resistor give negative feedback, this is very boring, you say it , we play video and this little $ pieces generally have prepared , if it does not keep , find demolition waste printed circuit board , and of course we will try to do , try not to let this happen.

2 .$ Pieces from small start welding, soldering and then a big , horizontal welding first , and then weld -standing .
3 .ToWhen the individual components such as resistors and capacitors $ temporarily missing parts such as ;Buyers need their own leveling devices, we can only refund the appropriate device models ; we are no longer a replacement ; we can do is do our utmost ability to avoid missing pieces ;$ Parts due to different batch , color and appearance and does not have the same picture , hope buyers understand ,For lack of parts need replacement / color demanding , do not shoot, thank you.
