Hi hope everyone is well. I recently purchased a few bits off aliexpress.com and saw a digital clock kit which I added to the order, it arrived and I managed to mislay it so the next time I was on the site I ordered another and in the time it took to arrive I'd found the original lol. So now I had 2 so decided to assemble the later one first, it went together fine and worked OK.
As I was on a roll i thought I'd do the first one. This kit was slightly different and also a component a 1n4148 diode was missing, a quick Google search said a 1n4007 diode I had could (in some circumstances) replace a 1n4148. I had some 1n4007 diodes I'd ordered for a pal, he needed one but I had to buy 100. I did the swap but it didn't light up like the other later kit, as the diode was rated for higher voltage than the original I decided to increase the voltage to 9 volts from the 6 volts I was using. It still didn't work but the 220 capacitor popped scaring the s#!t out of me. I'm really interested in working out if it was my diode swap or something else that happened?
