Little help :D

i will make another one with better solder

[jap]

Hi eessoo
-first re solder with a random suspect.
-Compared to the work of all the components and their values ??and installed in its place, especially in the area u2,u6.
-Measure -5v ,+5v.
- solder,, this is good with very high quality.
you will

any idea what could be wrong with the circuit ?
could the problem be with my soldering work?
is this a good solder?

Hi eessoo
0.6 bad . 0,-0.3mm ~0.4mm are good.

i used 0.6mm wire in a 26cm circle 26 turn
if i remove the coil it keeps BEEEBING

Hi eessoo
Test conditions in the home using a small diameter coil and should be lifted to the highest reasonable distance ensure that any affected metal surroundings as well as electricity wires - then start the test - -What are the specifications of the coil?

no matter what i do it keeps beeeebing

[eessoo]

jap i tested it and it gives continuous beeb
when i change the threshold the sound fades ( dose threshold control the volume f the speakers?)
can i use 220k instead of 100k in threshold or delay?

[eessoo]

all good?!

[eessoo]

what is wrong?!
wrong capacitor? the meter says 1nf
i bought the 220p capacitor (221 is written on it)

Hi Qiaozhi
Thanks,,,,, I know he does not ------ Note:Link to the relationship what has been written (102)and reading device (1.022)nf..So I asked him!!!!!

what 102 ?

102 is the code for a 1nF capacitor.

This is very basic stuff.
To decode the number 102, use the 3rd number as a multiplier. i.e. 10 + 2 zeros = 1000. This value is in pF, giving us 1000pF, or in other words ... 1nF.

In case you don't know the capacitor codes, then try using this ->
