I have tried in the simulation. You are right. Thanks a lot. I have spend a few hours, yet the fact that 2N3055 do not have enough gain just didn't cross my mind. Thanks again.
Regarding the power dissipated, thanks for the reminder. I will put that in mind. I will try to redesign the short...
From my experience, kalman filter use multiple input make prediction. By multiple input means it requires more than one sensor data to make the estimation. For example, the sensor is used along with gyro-sensor and accelerometer, then kalman filter maybe really helpful in that case. Anyway...
The figure shows multimeter at the output is in Ammeter mode which i think it functions as short circuit for the system.
Referring the picture, I attached. I have designed a series voltage regulator that can convert AC source to DC source (range from 0 - 20V). However, I could not achieve 5A...
You can try it with Input Capture in the PIC. Just connect it to the ccp pin. Once that parts works you can do all the manipulation with data you received.
Sorry i did not state the question clearly. Actually i saw the part "if(_test_struct.ptr_sum)" in others people code. I try to implement it by making some modification. The main point is that i don't understand why a void function in IF statement's expression will allow the execution of IF...
I connect the circuit at above and solder it, but it just does not work. The value of sw2 is not step down but the lt1073. Does this mean it is damaged?
when i do the stimulation using ltspice, althought i connect the circuit at above. it still need to put a Ground at the negative terminal of...
Ya, i am thinking of doing so too.Do you have any suggestion of which piezoelectric is suitable? it is difficult to get the suitable one.

That's is a good IC for this project. it can operate in low power as my project is using piezo for low power appliances. Now my only problem is to get the suitable piezoelectric as it is the main item for the whole project.

I looked into the keyboard. It cant be added magnet at the key, wont the keyboard hardware will be affected by the magnet?
I still feel using piezoelectric is nice but i just cant make sure it will work.
If i want to use piezoelectric, it is possible or there is another better idea to do this. My idea is to make it self-powered so that it could recharge the battery.
Can anyone give me an idea or improvement i can do with this project.
I could not find a suitable long strip piezoelectric for this project, could someone help me?
thanks
I knw that piezoelectric produce a low power. That is reason i would like to apply it in wireless keyboard which operate in low power. By typing it would eventually store up charges and charge the battery in that keyboard as we press the keyboard buttons a lots when using computer.
So, is there...
