Yesterday i had to replace SCART socket soldered to PCB.
That many pins looks very creepy to desolder but i’m being lucky and from around half year i’m owner of ZD-915 “china made :)” desoldering station.
I’v got idea to make movie from it, to let You guys see how useful this device is in real situation.
I could do this faster, but camera on tripod was blocking my movement 🙂
Some pictures
About month ago i found that my car cigarette lighter USB charger stop working…
After investigation and measuring voltages on output i found that problem is not in charger circuitry but in USB socket itself.
That charger was worth about 1 USD… but is it worth to repair?
I open charger, and check ebay (china sellers) to found same type USB socket.
I found 🙂 1 USD / 10 pcs with shipping included! I bought and pack all charger parts into ziploc bag for future repair.
After waiting time of 1 month , today my pack of 10 USB sockets arrived and i could start “repair”.
As You can see on last picture, my phone is very happy being charged 🙂
Repair took about 5 minutes
My conclusion:
I could order new one for 1 USD and put old to trash but instead of throwing out this 1 USD i got 10pcs USB sockets. I use one of this and i have 9 left in my “lab” for future experiments and of course working charger. 🙂 As You can see, sometimes it’s worth to fix something cheap 🙂
Today i got electronic device described as “not working”.
Device got attached to not original PSU made in China (PSP-2000) 2A 5V AC Adaptor.
I do quick voltage measurement and everything looks well. I check plug, same size as original so why it’s not working?
After quick observation i notice that device light glow very very very little, that’s give me a reason to suspect failed PSU.
PSU was very lightweight! Even switching PSU can’t be so lightweight at 2A.
When i cut off plug i notice very thin cables… they won’t carry 2A without major loss.
I break case and got into PSU… that’s what i found…
2A… ha ha ha at SHORT it’s product less than 600mA…
After using other brand PSU device start working well and i got pictures for first entry.
I often but china electronics, but remember “You got what You pay for” .
