Am I wright in thinking this is just a battery charger indicator and that little bit could be (er) robbed and used on any battery device ?
Thanks

yes certainly. it may be used in any device. I see this diagram in net. it was used in DP that has been sold.

greeting
Do you have any news from the PCB?
KT315 when it will be finished

[kt315]

greetings too... at this step... labtec, i promise you you will get the pcb FIRST!

[labtec1]

I finally made my DP but I can not get him to work
Behaves very strangely, between-12V and any pin on any IC has 12v?
The speakers will hear approximately 1 sec. crackling. As it is connected to the device for resuscitation.
Please help if someone had a similar problem.
thank you

for 30 h does not sleep and does it work DP
.
DP on my 13v is everywhere. It's impossible!
I do not know what more I could do than to start from the beginning and examine and change all


Does anyone who can write voltages should be on d4 d6 and since I do not have any DP who works with him, and to compare and I've never measured it
where are you going to check?
any help is welcome

Labtec its not a very clear picture, but what is the light brown colouration on bottom of pcb ?
for example where its circled with arrow ?

[labtec1]

PCB is very transparent and is seen in the background component and solder wire has in itself enough paste to clean so she stayed. to the left is not completely removed all the copper but that's okay because I checked each point several times in a short.
I measured the voltage on the attery is 14.4 V, although it would not be that bothered
I'm really desperate I have no more idea what to do.
Sorry for bad English

[kt315]

if you shoot by mobile phone camera use a magnifying glass. it is a simple rule. another way you will get only the blur pics.

[labtec1]

Once again, I have reviewed the entire PCB and I have found nothing
. Online I saw that someone posted a picture of the finished DP with the PCB. Is it Any Good?
I think I'm going to break with a hammer shortly entire PCB and make a new one.
I'm so disappointed. I do not know what could be the cause.
as to measure the wire - 12v everywhere. At one point I thought it was a faulty multimeter and then took the new!
Do someone could tell me where the voltage on what components should be. I'm sorry I do not have an oscilloscope. There are online programs that operate through the sound card as an oscilloscope whether someone has tried some of that, and what are the results
Question for KT315
whether the final audit that you set on the previous post I good side if you do not find a solution to this tomorrow PCB throw away where there are no people and start a new
Now I understand people who use crutches and sinker in search of gold. preserve the time, money and nerves

Here are some voltages I think it was posted by KT315

Hello to all my *** friends These changes delta pulse circuit shown in an Iranian forum you will approve http://www.4shared.com/rar/oOxbYIrc/...ector_con.html

yes, it is mine. I gave this because someone looks on the schematic and sees nothing. this is why in new schematic I did connect all lines.

your deep delusion is if you are soldering sockets for ICs thinking there is a contact. NOT. on board's Top Side the contacts are ABSENT you are NOT able to solder pins of the sockets at Top Side of board because that is impossible. in fabric made PCB all pinholes are METALLIZED but you fully ignore this fact.
