It’s an interesting writer HiFi speaker mentioned that it was very simple, but I do not know how much is true for sure. Used in the laptop’s audio output
The materials used in making speaker
Foam Plate, isolated copper wire 0.202mm (awg32), tape, glue, tape paper, audio input jack for cable and neodymium magnet
Neodymium magnets are more powerful than those used in many speakers I could be wrong but I do not remember there were small pieces of hard disks
Hi-fidelity Loudspeaker
And speaker with battery test is done after construction + – poles and is working to find a simple test. Wrapped items to the ends of the wire the + and – on the coil is allowed to touch the tip of the plate up, if it moves forward + battery + terminal on the end of your speaker wire while the other – end

Coil, Bobbin, Winding Counter Circuit PIC16F877 PicBasic
@ Mustafa_cmbz of Picproj forum sharing my brother ever sip of counting projects PicBasic detailed project I have ever seen. Pressure. Hex files have pcb ares isis simulation. Thanks to those who contributed
Scanning display and key-pad when working on one for myself and I thought I’d bobbin winder circuit and appeared something like that. As a result of work on the project while doing my research I could not find documents related to the INKEY command. If more than one circuit is not required to be at least in terms of sample thought it might be helpful.
