 Cheapest signal cleaner circuit

Monday, September 29th, 2014

Here is the simple low noise filter circuit for any FSK signals that weak and have noise. This use few parts so easy and cheap. Fig 1: The schematic of this project As Figure 1 is the schematic diagram. This circuit include the low filter circuit through R1 and C2, the frequency cut off at […]


 Traffic light controller circuit

Sunday, September 28th, 2014

Today, let’s look at 2 model of traffic light circuits. They use the LEDs for display and the digital circuit as based. This circuit include IC-4027,CD4017,IC-555 and a few parts so easy and cheap. First model circuit. This circuit is designed in first. We use many circuit to mix together. As circuit in Figure 1 […]


 CD4027B_datasheet of Dual J-K Flip-Flop

Friday, September 26th, 2014

Here is the datasheet of the CD4027BC dual J-K flip-flops are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors. Each flip-flop has independent J, K, set, reset, and clock inputs and buffered Q and Q outputs. These flip-flops are edge sensitive to the clock input and change state on […]


 The experience to Buy the components at icstation.com

Thursday, September 25th, 2014

Sometimes I can not buy electronic devices. Because, far from an electronics store. No products you want, or expensive. I always use the online order. I envy my friends who live in America. That they can order electronics from amazon.com. There are a lot of items. Very cheap, fast delivery and free. But now, I […]


 Simplest slave flash trigger circuit

Wednesday, September 24th, 2014

- This is a simplest slave flash trigger circuit. – It will help the slave flash immediately works almost simultaneously with the main flash. – This circuit better than others circuits because without the external power supply. – Since (look at circuit below) use the solar cell get light from the main flash. – The […]
