ok, so it’s been awhile since my last post. I’m likely to say this many times, but I have great aspirations of blogging regularly and then it just never happens. I’ve started writing “Hard Drive Repair by Removing and Replacing the Head” and taken pics of many more of my HW repairs but just haven’t given myself the time to do the repairs and write about it. I repaired the master volume potentiometer on our Clavinova CLP100 last weekend using a similar part (not pin compatible, however) from Digikey and completely forgot to take any pictures, so that won’t be coming to this page, either.

Next week, however, I hope to have my first PCB back from the fine folks at BatchPCB.com (well, now, I haven’t seen my PCBs, so I might change my mind about them!)… and I intend to do a write-up on it.

I’ve got a few kids in the house and I use my garage as my “lab”. Most of the tools I’ve got are pretty safe, but I’ve got a few soldering irons and a heat gun that could be dangerous toys if they were to be used absent of any adult supervision. The PCB I’ve got coming is a shield for an Arduino that adds a 12-key keypad, dual 7-segment display, and connections for up to 4 125V/15A relays. I’ve got a first run of the code completed and what I’ll have when I put it all together is something much like the security control one of the big home improvement stores puts on their saws or bolt-cutters they use in-store.

I’ll post pics and an update when the stuff comes in. I may even have an extra board or two if all goes well.
