Find out if you are a Extroverted, Neurotic, Psychotic.:eek:
...Your resistor would be something like (Vsupply-(Sum of all of the Max Vf's))/(operating current)
e.g.R<=( 5-3.1)/20E-3 A 3.1 V LED on a 5 V...
Market forces are tending to push prices up for magnetic strip and down for chip.
Must be a really disadvantaged country - we're being swamped by...

A Dremel with a cut-off disc will do it!
There's usually a tape guide "fence" spot welded to the side of a cassette head - they don't always pry off without wrecking the whole thing....
...experiment with one of these, all you need is to interface the output to a suitable IC and serialize it, this is all that was used originally.
...generally Murphy's law applies to electrical enclosures, the required calculated size always equals less than finally required in practice!:(
...to the threshold voltage starts opening the valve. When you apply Vgs(max), the valve is completely opened and you have the lowest resistance...
Let me start by saying I'm pretty ignorant when it comes to the various motor types. To the best of my knowledge, these are centrifugal switch...
My neighbor did the one with IBM and National geographic. Seemed to fit pretty good, but he was shocked his oldest ancestors were from Africa. :eek:
I can't comment on that, I only used assembly, the older method shown in the OP was also used originally in the assembly version also.
Your right. To make things interesting they do it differently in .asm and .c files.
I don't think your version will work in C. See section...
...so tomorrow to see if I can get any improvement on the simulator program I am using.
Thanks for your reply Max, in time I'm sure I will get...
I'm just wondering why almost noone uses smileys here on the forum?:confused::(:rolleyes:
The outputs load of the ULN2803 should be going to +DC not the DC common terminal, (or earth GND as you show it).
