off work today suffering with man-flu….. which is good (in some ways) as i just received a few ssm2164 and xr2209 ic’s, however i really cant be bothered unwrapping myself from the blanket and falling off the couch to go and experiment with them, so instead i shall be perusing the datasheets from the comfort of my warm little bubble of illness and consuming gallons of lemsips, water and chomping through some paracetamols.
things on the list to build with these:
ssm2164:
- vca’s (linear and exponential response)
- sinewave vco’s
- 4 pole low pass vcf
- and i might splash out and buy a thomas henry mankato pcb from magic smoke
xr2209:
- vco’s (obviously)
- er….. thats about it.
the xr2209 is similar to the now discontinued, expensive and hard to find 566 vco ic, so it’ll be interesting to see how this wee blighter copes. it only has linear response but i’m hoping it’ll make a good substitute for the vco in the dub sirens. i’ve built nearly 30 of those now and have depleted the stock of pcb’s i had for them, but the parts count was huge for what should be a simple circuit, plus these are still analogue, which we all love don’t we?!
i think i’ll lie down again before i fall over….
