Re: Coming Soon - Through Hole Universal Model F and Beamspring Controller

on the note of atmega being single sourced: duh, but my point was that its possible to swap out the microcontroller for another, only making some modifications to the firmware. Oh, _that_. No difference there either. All the FPGA stuff can be pulled out and implemented using discrete logic and driv...

Re: Coming Soon - Through Hole Universal Model F and Beamspring Controller

Id like to make the argument that the CommonSense controller does not use an "off the shelf" part. its a specific part that isnt made to by any other manufacturer, where as with the XWhatsIt design you can swap most of the parts around for other components, no particular reliance on a specific manu...

Ooh, this does look promising! Though admittedly CommonSense still has the advantage of off the shelf parts, even if it is a bit of a pain to configure.

Re: NCR K430 magnetic valve - Fixed! - second row from bottom was dead

May I ask a question about the PCB layout? What might be the purpose of the extra columns without holes in the loops, in between the columns which have holes in the loops where the ferrite beads attached to the keys pass through? Do these serve as reference loops against which the sensor loops are ...

just make sure to be very careful in sanding that connector, you're only trying to break any oxide or light corrosion, if you see copper STOP!

no its almost certainly the edge connector. ive restored a handful of 5251's its usually the only place they can stop working, even with corroded looking pcbs. get some 1k grit or higher sandpaper, and use some isopropanol to gently sand the connector. since you've got it apart already clean the pcb...

Re: Modern Beamspring? - The Silo Beam Switch

you'd need a custom PCB made for any existing boards, due to the hall effect sensor. i guess they could have gone with a 2-wire hall effect sensor and integrated it into the switch, but that means reliance on one sensor, and engineering a custom frame to hold the sensor; engineering an assembly proc...

yes, should be safe to remove that, and recompile. I've also re-written a good portion of that code as well, as the macros IMHO don't allow for a more maintainable code-base, but that's just a personal code-smell kind of thing. let me know if it still doesn't work right, i might have accidentally m...
