The REES52 Promise
The REES52 Promise
We want you to build, not worry. Here is exactly what happens if something goes wrong with your order.
Dead on arrival or defective? We replace it.
If your item is dead on arrival or has a manufacturing defect, tell us within 7 days of delivery. Email support@rees52.com with your order number and a short video or a couple of photos showing the problem. Our team will get back to you within 24 hours and arrange a free pickup from your doorstep - you never pay return shipping for a defective item. Once we verify the issue, your replacement ships out right away. If the item is out of stock, you get a full refund instead.
Refunds, with real timelines.
- Approved refunds go back to your original payment method within 6-7 working days.
- Missing item in your package? Tell us within 7 days with photos of what arrived and the parcel label. Once confirmed, the refund for the missing item reaches you in 2-3 working days - or we ship the missing piece free, your choice.
- Every refund comes with a reference number by email or WhatsApp, so you can track it with your bank instead of chasing us.
Wrong item or not as described?
Email us your order number and a photo of what you received. We arrange the return pickup, and ship the correct item as soon as the return is on its way. Prefer your money back instead? That is fine too - full refund, same 6-7 working day timeline.
About lead times on some products.
A few items on rees52.com are sourced from our overseas partner warehouses and are not sitting on our shelf. Those products show a lead time of about 20-25 working days on the product page, before you pay. If you order one, we keep you posted as it moves. Changed your mind while waiting? You can cancel any time before dispatch and get a full refund within 6-7 working days. No cancellation fee, no questions.

Introduction
In this video we will make a 5 led chaser circuit using BC547 transistor and capacitors.
All transistors are BC547 are used in this circuit can be replaced by 2N222 transistor. You can use capacitors between 10-100 µf and resistors between 10k to 50k.
HARDWARE REQUIRED
- Resistors (10K – 5 & 470 ohm - 5)
- Capacitor 100 µf – 5
- Breadboard 830 pt. – 1
- Transistor BC547 - 5
- Single stand wire 2mt – 1
- Led 5 mm – 8
- 9v Battery - 1
- Battery snapper – 1
SPECIFICATIONS

Capacitor
BC547 Transistor
CIRCUIT CONNECTION
- Attach all the transistor to the breadboard
- Connect Base pin of all transistors to the positive rail via 10k resistor.
- Connect cathode pin of leds to the collector pin of each transistor
- Connect anode of leds to the positive rail on the breadboard via 470-ohm resistor.
- Connect emitter of each Transistor to negative rail on the breadboard.
- Connect anode of capacitor to collector of first transistor and cathode of capacitor to base of the second transistor
- Connect similarly all the capacitor with transistor.
- Connect anode of last capacitor to the collector pin of last transistor and cathode of capacitor to Base of the first Transistor.
WORKING AND OUTPUT
After connecting the battery, you can see the chasing effect on all the leds.
NOTE:
You can adjust the rate of blinking and chasing by increasing and decreasing capacitor’s and resistor’s value which is connected at the base of the Transistor.
