Oil burning furnaces have a nice transformer that sits on top and generates a few thousand volts for the arc gap.

Re: What pointless thing are you doing right now?

Keeping the creativity ball rolling. So today while working on the backlights of a 32" LCD panel I looked at one of the broken tubes and wondered if I could melt the jagged end with my butane torch. I could. I made a straw once I fed a pipe cleaner through it. Then I wondered if I could shape t...

Re: What pointless thing are you doing right now?

I just photographed the total bajeesus out of a UCC model 1035 terminal that uses a Selectric II with a fair number of hacks. http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/UCC_1035/CGS_7573.jpg http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/UCC_1035/CGS_757...

Re: your latest purchase

I did it again. I splurged $100 and bought an arcade cabinet I can't store at home, so it's being "loaned" to the local Makerspace. http://i11.photobucket.com/albums/a166/ballsandy/New%20Bucket/CGS_7543.jpg http://i11.photobucket.com/albums/a166/ballsandy/New%20Bucket/CGS_7544.jpg It doesn...

OpenGenera VLM

This is something more out of idle curiosity. It seems originally it was only for Tru64 however someone rather recently ported it to Linux. The documentation to do so is available here . Without sitting in front of a 64-bit machine myself (I only have the O2 up at the moment) it seems all you need i...

HP Disk Modules

I have an A3515A Intelligent disk array and I've noticed it uses the same style sleds as my D350. They seem to come in both LVD and HVD flavours, marked with a yellow or purple SD or DF sticker on the front of the module and either SE or DF stamped on the PCB inside (but the components on both types...

Re: your latest purchase

I mean, 50 hours does not sound like much but then I recall most of my prints go under for 15-45 seconds. Longer if I'm doing something crazy. It will still take a while to reach 50 hours.

Re: What pointless thing are you doing right now?

The old HP RP5700 that ran my chipping station died. Had to rummage around for another box that had a physical parallel and serial port. While I was reinstalling I also added support for reading and writing to RFID. http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/IMG_7683.jpg

Re: IBM AS/400 OS/400 questions

There is some form of a webserver you can run however as you might of already noticed the licensing tiers on just about anything in the machine will drive you wild.

Re: What pointless thing are you doing right now?

I'm admitting I did something slightly dumb because I thought it would be cool and for my local Makerspace I've been advocating replacing the existing outdoor lights in the parking lot with mid-century fluorescent lamps. On paper it sounded great and I secured two lamps for a test install. They need...

Re: Acquired a PS/2 Model 60 with Reply Corp PowerBoard planar replacement

Alas, you are correct in that you need a special floppy. All of the Microchannel machines needed what was called the Reference Diskette to self-configure when the battery was changed or you added/removed boards. The diskette is different for every planar but MCA machines are well documented so if yo...
