Fred:
Looks really clean Bill !  :clap:

billscottni:
Thanks Fred.

I'm not the best at electronics, but I got a good deal on a temperature controlled soldering iron at Maplins, so all joints are done at the same temp. Hopefully this has prevented any of the components "blowing" in construction.


Testing tomorrow, wil determine if I'v done it right :?:

Happy Days:
Well done Bill. The only components that are likely to “pop” during soldering are the semi conductors. :!:

I see you’ve wisely soldered sockets to house the chips…..good idea, :clap:  They can be very temperamental not only to heat but to stray voltages as well.

I also notice you’ve only posted pictures of the component side of the board,………not the soldered side! Come on, be brave,…..lets all have a look at Bill’s soldering Ha Ha! :lol:  

(Tip: Before you apply 12v, check, :?:  and then double check the polarity of all active components. i.e. diodes, transistors, i.c. sockets, and polarized capacitors’)

billscottni:
OK Keith just for you :wink:



Solder side of the board

Only 1 of the chips has a socket, four others have to be soldered in. I intend turning the heat down on the iron for those!

billscottni:
The chips are stil in their anti-static bag:



Honest, there are 5 chips in here, 1 is very small and fits the socket

These will go in tomorrow, assuming the 12v tests go OK
