The distance is not very important now. Maybe 100 meters is unrealistic. I will be happy with 30 meters for now.
Actually I am not sure whether I need and encoder or not.
Can you please explain, what advantage I would get if I use an encoder in this particular application. Also what...
Hi,
I was stuck with other work for the last 2 months so could not proceed with my project. I am still at level zero to be honest.
Meanwhile I decided on my spec somewhat, don't know how much can be achievable:
1. Wireless Range - up to 100 meters
2. Frequency - 2.4 GHz
3. System needs to...
Thanks for your reply.
I am not not looking for a solution using a PC.
I will use a PIC micro-controller to handle the data processing. For now I am looking for some expert advise on ADC + DAC selection which can be used with audio signals.
thanks..
Hi,
I am working on a digital guitar wireless unit project.
So in the first phase I will need to convert my guitar signal into digital data which can be then transmitted over any wireless system, i.e. wifi, bluetooth etc.
Later on I will make the receiver part where I will need to convert the...
Thanks for your reply.
Actually I am trying to generalize the relay spec for different single phase AC motors. 1 HP being the maximum rating among them.
I am getting 4 Amps at 90% efficiency from this calculator for the above specs.
So does it mean that I need to choose a SSR with 40 Amps...
Hello,
I have the following specification of an AC Motor:
- Single phase AC motor
- 1 HP
- Works at 230 Volts
I want to control this motor (ON/OFF) using a Solid State Relay. I am facing difficulty in finalizing the specifications of the SSR which I will buy.
Can anyone please give some...
Hi,
Thanks for your reply. The output power concept got clarified from your reply.
Yes I will be able to solder it on a SO-8 adaptor.
The load impedance of the earphones will vary. It can be 32 ohm also and 4 ohms also. The datasheet of TDA2822D does not say the output power for a 4 ohm...
I think TDA2822D is available in element14, but it says this chip is a Class AB amplifier.
Can you please guide me, how should I compare TDA2822D with LM386 with respect to power consumption and performance. What are the main parameters which I should check in the datasheet to get a better...
Hello,
I am looking to design a simple stereo headphone amplifier circuit to be able to amplify a electric guitar signal and drive a 4 ohm and 8 ohm headphone. I want it to be battery (1.5V x 2 - AAA) operated, having a decent battery life.
I was searching through Google and found that Class...
I have built 4 such boards using a ZCS Optocoupler (MOC3061) and a 4 Amp Triac (BT136). All of them seems to work properly without any disturbance. I have used the same circuit as given on the MOC3061 datasheet and I have put a snubber circuit also as you have recomended. I have tested this...
I have attached my schematic and photo of the veroboard. The photos contain the assembly circuit also where 2 Relay-FF boards are connected together with the controller board.
I am using the same power (vcc) and gnd line for the relay and the other circuit. Here VCC = 5V. Could this be a...
Hi,
I have made the change in my circuit. Instead of the 680 ohm I have put a 1k as I didn't have the 680 ohm with me. And I have also added a 1k bleeder resistor from the NPNs (Q4) collector to VCC.
My entire setup is on vero board. I have three different vero boards each having the same flip...
I need the delay circuit because I am cascading many of these flip flops together and driving them from one source, i.e. data and clock signal. Here if I do not add the delay the output of each flip flop will flicker if I want to change only the nth flip flop state.
I require the delay to...
Sorry for such a late reply. I was stuck up with a different project.
I have setup the entire circuit on a vero/strip board. My new circuit is attached.
Now I have a relay at the output of the D flip flop. I also have a small delay circuit in between the relay and the D-FF output. It is just a...
