Best / easiest way to convert 5 V into 12 V?
« on: 17:03, 14 October 19 »
The solutions I found on the web are kind of involved.
Anybody has something simple? The simplest solution might be to add a socket for 12 V from the CPC monitor... but how about 464 users then.

Rather than doing it myself, I might just add this thing to the PCB:

Is that a good idea?

I bought a couple of Bryce's 5VCPC, which I'm really happy with. One in the back of my floppydrive on my 6128, and one placed underneath floppydrive on my 664. I only need to connect 5V power to my 664 and 6128. Dunno if they still are produced.

((lambda ()))  -> nil

else:

((lambda (x) (funcall x x))  (lambda (x) (funcall x x)))

 :D 


To decode that - I wasn't aware of the Bryce converter and that it had sparked *considerable* discussion in the past, and it was not my intention to reopen that thread / discussion - so, let's terminate this discussion with the empty list rather than a stack overflow.

  • It's not broken, it just hasn't been fixed yet.

Hi,
     I probably still have a 5VCPC somewhere, but they are designed to only supply 250mA with 500mA peak and the physical shape is optimised to fit onto the back of a floppy. The device you've linked to looks ok, but it's seriously lacking capacitance, so it will be dumping a load of high frequency noise into your circuit. If the circuit has anything to do with sound (as I suspect), then you'll notice it a lot. It uses a very small output capacitor which would suggest that it's switching at a very high frequency (MHz), probably with lots of harmonics (not the musical type :D ). If you do use this part, you'll need to add a decent low-pass filter.

@TotO: Pas de soucis, tes fesses sont en sécurité ;)

Bryce.

Ist Französisch hier jetzt so ne Art GEHEIMSPRACHE?
Dann kann ich ja auch einfach Deutsch schreiben, oder?
Und mittels Google Translate kriegt man das nicht übersetzt?
Na dass ist ja pfiffig  8) :P :laugh:

French is the official european language before and after brexit, so better to practice it!  ;D
