Oh dear. Sleepy monkey.

Morning drivellers

You know it's going to be a bad week when your struggling to stay awake at 10:30 on Monday Morning

been a good weekend

(As the teacher said: 'mock up then cock up').

We queried that and he just rolled his eyes.

Doing a prototype did not prevent us cocking up our circuit boards; it merely reduced the amount of cockups.

One of my projects was a variable output power supply. It had a 16 pin chip in it (for some reason, I forget why).

I had misunderstood the pin-out diagram in the RS catalogue and spent a scary hour very gently binding all the pins on the chip to go up instead of down so I could solder it in the wrong way up.

Oh the relief.

The esteemed customers have all buggered off.

I had misunderstood the pin-out diagram in the RS catalogue and spent a scary hour very gently binding all the pins on the chip to go up instead of down so I could solder it in the wrong way up.

Nothing to be ashamed of there... the first Spectrum had a dead bug chip in it...

And I did the same thing back in the black tape days with a voltage converter chip... though the datasheet for that gave the topview rather than the bottom view of the pinout.

Not only that, but CadStar did it last week... for some reason if you mirror the component (a transistor) on the schematic (circuit diagram), it thinks you want to mirror it (put it on the other side of the board) on the pcb...

I was ever so please to find that it had done that to a transistor on my dtmf decoder thingie that I built on Friday.

Most schematic capture packages wouldn't do that... there's no link between the orientation of the part on the cct diagram & that on the pcb.

Ho hum.

Morning everyone

Morning CM

Haven't we forgotten something?

[zeitghost]

Bored now.



Again.

I may have to do something more interesting.

I've already rewired the charger for the B&D versapak batteries coz the plugtop part had burned out... I wondered why the drill was getting slower & slower...

For my next project I was thinking of designing a dual axis suntracker for a solar panel.

Sadly I can't understand all this azimuth and elevation stuff...

Should be easy enough if I can get my head around the maths.

So.

What's this "cos" thing then?
