Analysis: fine grade thin synthetic oil, like sold in little cans in sewing machine stores. He feels, however, that this is probably unnecessary with a blower as small as 1/4 or 1/3 HP, as there is no real weight hanging on the bearings, so that ordinary 3-in-1 oil will do. The Laukhuff machines have a sort of wick where the oiling takes place, and they suggest once every ten years. I had a Bobco, too, and a squirt every year seemed to keep it happy for the decade or so that I had that organ. So I guess the answer to oiling is "common sense." Somebody must have some paperwork from Meidinger that tells what they suggest.

(back) Subject: Reed switches, manual vs. pedal From: <gzlmn@iwaynet.net> Date: Sat, 7 Feb 2004 11:00:20 -0500   Another little tidbit with reed switches that I've noticed: They do not make and break at exactly the same spot. The tiny difference in small fraction of an inch makes no difference with pedal contacts, but might just be difficult with manual key use.   Cheers.

(back) Subject: Re: [Residence Organs] Diodes and electronic parts From: "Drew Taylor" <dhtaylor@netmcr.com> Date: Sat, 07 Feb 2004 13:29:14 -0500   For small electronic parts such as diodes, transistors, reed switches and etc, I use www.allelectronics.com. Their website is easy to manipulate and their prices are very good for most items. Many basic electrical componets found in the OSI catalog can be purchased much cheaper from electronic surplus suppliers. I only use digikey for huge quantity ordering and purchasing ICs or other hard to find parts. I don't work for All Electronics but I have purchased many parts from them for my organ and have been happy with their service.   -Drew Taylor

In particular look at MIDIbox NG, the newest version of MIOS (MIDIbox Operating System) and the MIDIO128. The MIDIO128 interface enables you to drive up to 128 digital output pins and to react on up to 128 digital input pins via MIDI. Everything - pc board layout, schematics, software, etc. - is available for download and free. The only stipulation is that it cannot be sold as a commercial item. The pc boards are also available pre-made, and some parts are available as kits. See the FAQ for more information. Also check the forum for lots of good information.   Later,   Mickey   ---- Mickey E. Sadler Dublin, Ohio

OSI wants $17.80 for 100 and All Electronics is priced at $9.00 for 100. Are these diodes the same?

In particular look at MIDIbox NG, the newest > version of MIOS (MIDIbox Operating System) and the MIDIO128.   Is anyone on this list actively using the MIDIbox in their installation?   I recently ordered a 'starter kit' and am building a small board that will translate between my console which uses system exclusive messages for stop control and the YAPPI boards that I am using that rely on either controller messages or program changes for stop control. I'm in the process of figuring out the memory architecture of the PIC 18F452 microcontroller which can best be described as 'bizarre'.   I had written a windows application that did the same thing but I am interested in setting up my 'system' so that it doesn't require that the PC be turned on in order to function.   The MIDIbox will soon have sequencing capabilities. This will give me an easy way to 'demo' my organ when guests come over (remember, I don't really play) without having to fire up the PC or a MIDI filer or whatever.   I am woefully behind in updating my website to share all this pain and pleasure but I have high hopes that I will get more information up soon, including a review of the new chimes driver board I purchased that is controllable via MIDI and is velocity sensitive to boot!   ---john.

Is this the only kind I can use for both spark suppression on the direct electric magnets and the switchstack or can I purchase diodes with other specifications? The reason I ask is that there are great deals for diodes on eBay but they aren't the 1N4004 type.   Steven   ----- Original Message ----- From: "John R.
