Happy New Year!

 Here's hoping '24 will be better than '23. I really don't need any additional Hospital Time.

Winter's been a big bust so far. There's been a decent amount of snow in the mountains (still below normal), but nothing down here in the foothills. We have no snow on the ground, and it's hasn't rained in quite a while. The yard plants are desiccated, and without a snow cover, things around here just look all dried-out , desolate, and dead.

So here's my best wishes for all my friends to have a Happy New Year. Keep your head on a swivel, be vigilant, and may you all Live Long and Prosper.

Failed to Publish. Try Again Later... Say, What?

 Huhhhhh....Can't reply to comments in my previous post. It just belches out the reply in the title.

Wonder if I can make a new post? Good Gravy, it's freakin' WINDY tonight. The weather station is reporting pretty steady ~20MPH winds, with gusts to ~35MPH. Sorry guys, can't do it in knots. The weather station only gives me MPH and KPH, although with a bit of code editing, I could add that feature pretty easily to the software used to get it on the network. Gotta love Open Source.

Here we go....bonna pull the pin and lob this with the "Publish" button.

Merry Christmas

 All the kids and the littles will be over this evening to have our Traditional Christmas Dinner of Sloppy Joes, French Fries, and other things to nibble on.

Wishing you all the best for Christmas and the coming New Year.

I just hope the road's a bit smoother this coming year!


Peace to All Men of Good Will.....

How Do You Guys (and gals) Manage Your Blogging?

 I just don't understand how people who blog can be so prolific, and on a continuous basis. There are times I posted daily, like when I rebuilt the suspension on the Supra, or on various other projects, and during our move here, but it seems like I just run out of steam at times.

I stick to techie and humor stuff, things I know well, and stay away from politics, which others know far better. Besides, I have to watch my blood pressure, and discussing politics gives me heartburn!

So here it is, a week from Christmas. We have *some* snow still laying around, the streams and drainage ditches are full of frozen water, and the damn geese are all over the place, but it doesn't feel like "Winter" this year. Houses are decorated, and our neighbor at the end of the street collaborated with his next door neighbor, and have "crossover" decorations. One of which is the Grinch and Sam, in neighbor #1's yard, pulling down the lights from neighbor #2's eaves. Funny and creative, and I'll bust out my tripod so I can get some decent 'available light' pix of it. NWS is saying there's a "Chance of Snow" for Christmas Eve and Christmas Day, and the Denver and Front Range Weather guy on Fakebook says it might be nothing, and we might get clobbered, as there's TWO systems which will converge this weekend.

So have a good week, stay observant, and always remember....

Geez....AWOL again, Jim?

 Yeah, been another week lurking in the basement slaving away over some "Hot Tinkers". Can't show you pix as it was a paying customer with a God-Knows-How-Old-It-Is sick Fender Twin Reverb (A blackface, no less!), and he wanted it yesterday. As in BIG $$$, Have The Parts Shipped Overnight, yesterday.

 Made me an offer I couldn't refuse for my labor. I've worked on quite a few of these, and the whole key is understanding their lineage. This one dates to the late 1960's, and while well used, it was in Very Good condition.

This will help with the Christmas gifts I purchased over the last couple of months.

As promised, we had an episode of "Baking With Grandma!" take place over last weekend. This was the "Don't bother us, we're doing the second batch!" scene:

And I'm busy doing several things.

1)Finishing up those speakers that got delivered during The Week Of The Femur Fracture. Should have them in use by Christmas Day, God willin' and the paint dries hard!

2) The aforementioned Fender Amp repair.

3)Misc things involving the recommissioning a Windows 7 PC, and getting my instruments on the HPIB. Anybody know HP/Agilent/Keysight VEE? Any LabVIEW users? I really want to get my HP-8903B Audio Analyzer automated so I can do swept measurements automagically, and plot them.

4) And I'm doing my "second batch" of Nakamichi BX-300. Since I can find no evidence of the cover ever being removed, this is quite likely the first time anybody's ever been in the unit. I took a lot of detailed photos of mundane things like how the cables are run, how many, and where, are all the cable ties, and other stuff of interest.

Here it is with the transport out. These are much easier to work on than that Pioneer I got burned on. I think it's built better, too.

This will have all new belts, a new idler assembly, and a set of "Athan" pinch rollers when it's finished. This one is a much later SERNO than the one I just shipped out, so it should sound really good when finished.

Oh, I'm building a 1:12 scale model of a 1982 Supra. I have all the various kits of Supras that I was able to find, and I picked the simplest kit to start with. Simple interior, no engine, and the white plastic the body is molded from is very close to the white my 1:1 scale is painted. The interior was molded in black, so I painted it with SEM "Shadow Blue", which is an exact match for the real interior out in the garage.

Still Here, Still Busy, Proper Post in Progress!

 Been super busy down in the shop. I had a PC I built for Audio/Video work some time back, so I finally took a deep breath, and decided to repurpose that one as the "Lab PC". All my HP equipment has an HPIB/GPIB Interface, and I have plenty of various length HPIB cables, and a Prologix HPIB-to-USB interface. Ultimate goal is to automate my audio testing with the HP-8903, and automate generating RF signals from my HP-8657B, modulated by the HP-8904A Multifunction Synthesizer.

And I have some "Baking with Grandma" stuff, too.

Enjoy your coming weekend, and stay observant.

Tap...Tap...Tap...This Thing Still Work?

 Yo...been incognito for a while. Sweet Little Wife had the flu, and COVID, and then it was my turn. Which occurred at the same time I was having the post-op results (passing blood, clots, discomfort) of the TURP procedure. I mean like LOTS of passing of Red Stuff and Chunks of Red Stuff. Not real pleasant, and I went through a whole package of Depends. But, all things must pass (couldn't resist it) and this did, too.

And I'm still having some "echoes" of the August-spend-your-birthday-in-the-hospital incident. Have an appointment tomorrow afternoon about that, so I'm hopeful.

So.....I (finally) finished the Nakamicih BX-300 cassette deck, and shipped it out to a very patient member of the Audiokarma forum. Thanks, Bob!

And Ye Gawds....does it sound GOOD!

I haven't heard Buffalo Springfield sound so good in 50 years!


Of the two decks I bought, this one was the "beat-up" one. It was filthy inside and out, and the belts had turned to goo, but the heads scoped out perfect, so I went ahead gave it the Full Monty. Even beat-up, it had several bits in better condition than the #2 unit, so it donated those. While this one has all the warts and blemishes of both units, it works spectacularly well, and the buyer gets a 100% functional, but not pretty, deck for half the going price. And I made a few $$ on it, too. I'll never get rich doing this, but it helps defray the cost of my stereo habit!

Well that's it, comrades. Still here, still ornery, and still above ground. Been a bumpy ride this year, and we're hoping the coming year won't be like the last.

I got too much stuff to do!

Meanwhile, Back On The Workbench....

 Where I've been finishing up a Nakamichi BX-300 cassette deck. I bought two of these on eBay, and pulled the best cosmetic parts off both to make one nice unit.

This one has all the warts and bruises from both units, but works perfectly. I put in new belts and idlers, gave it a complete cleaning and lubrication, and then started going through the Adjustments and Calibration section of the service manual.

And there's a ton of adjustments for each of the three types of tape it can use. "Type I" is good old recording tape. Been around since the 50's, and still works fine. "Type II" are the "Chromium" tapes, which came out in the late 60's. "Type III" are the "Ferrichrome" tapes, which never caught on, and "Type IV" are the "Metal" tapes, and are the height of analog cassette recording.

And they're all buried under the wiring harness. It took about 30 minutes of cutting cable ties and rerouting the cables in the harness just to get this access to them:

These six are for the Record Equalization (aka Frequency Response), and there are six more for the VU Meter Calibration.

Should be a very nice deck when I'm finished with it.

SLW and I have been under the weather with a bug, so that's why the light posting.

Spectacular Weather

 What a gorgeous day! 

70*, blue skies, puffy white clouds, and light breezes. I'm pretty sure this is The Last Gasp of Summer before Old Man Winter stomps his foot down.

The front and back yards are covered with leaves, and the trees still have leaves, so we're calling off the Great Leaf Extraction for now. We just can't see doing it twice when if we wait another week or two most of the leaves will be down.

Supra parts cleaning is going well, and all the bits I removed from the engine will soon be cleaned and bagged. Re-installation will wait until I clean up the left side of the engine block and cylinder head. The fuel filter with an Unknown History will be replaced, along with a preemptive strike to change the starter for a Denso Re-manufactured unit. I'm going to do a Forensic Analysis of the fuel filter by cutting it open, and seeing what it's trapped over it's service life. Probably be interesting and should give me some idea if the fuel tank is rusty. I'll be replacing the master and slave cylinders for the clutch "While I'm In There", and I'm replacing the flexible hose between the master and slave with a stainless steel braided line. AFAICT it's the original hose, and they get soggy over the years resulting in them ballooning up when the clutch is pressed in. It's much nicer to put clean parts back on a clean engine than to fight with the grease and crud. Makes it much easier to see all the bolts, too. Supplies have been ordered to rework the wiring harnesses in the engine compartment, and I'll be pulling the battery cables out tonight so I can figure out what length and configuration I need to order from the vendor.

Election Day is coming, and our ballots are filed out. We're voting NO on most of the items, especially Prop HH, which is a thinly disguised end run around TABOR, our Taxpayer Bill Of Rights. It's similar to what "Prop 13" was in SoCal, but has other provisions included.

Enjoy your weekend, and keep thine head borne by a swivel!

BOOOO!

 The Little Ones will be over tonight to raid the neighborhood of candy, while I'll have Door Duty to hand out the treats to the various raiding parties who'll show up. Not sure what we're going to do with Pebbles, as she'll want to meet-and-greet all the visitors who come by.

My costume? I'm going as a battleship......

Active Weekend

 Been running around trying to be myself again, and actually got a bunch of stuff done. A good chunk was paperwork in the design-and-chase-parts-for category for the electrical subsystem in the Supra. I need to replace the crusty, brittle, 40 year-old, barely-big-enough battery cables for newer, better ones. I found a place that makes beautiful custom battery and other power cables for a reasonable price, and since they're custom cables, you can have them made with other leads coming out on either end. This opens up an area that needs improvement on the car, and will allow me to integrate the function of the disintegrated and unobtainium "TB1" terminal block into a more functional "Terminal Block Assembly", and bring all the power wiring up to current standards. It will also allow me to easily upgrade the cable from the output of the new high-current capable alternator to the car's existing wiring harness, and allow me to easily add the two new relays for the electric fans (the fans, shrouding, and new aluminum radiator arrived last week), and the two new relays to properly power my 125 Watt high beams.

There are three distinct wiring harnesses under the hood;

1) The main 12VDC Harness for charging, starting, and lighting distribution

2) The Fuel Injection/Sensor Harness that runs to the Engine Control Unit on the passenger side of the firewall

3) The Fusebox/Main Distribution Harness, or "Everything Else".

This is the existing mess at the positive battery post, where the #1 harness begins:

Toyota just used a stud and ring lug to attach the fusible links to the Battery positive post. Pretty crude, and prone to flexing and corrosion. "TB1" is dead center in the picture. It's toast. I don't trust those lengths of fusible link wire, either. Looks like a whole buncha bad connections to me. Checking my sources, calling around, and cashing in a few favors, has found ZERO of these in Japan, Down Under, or on The Continent. Decent to Very Good used ones are out there, but people are loathe to hack one off an otherwise perfectly good, and therefore irreplaceable and valuable, wiring harness. I don't blame them. This car is never going to Pebble Beach, so if I have to replace it, upgrade it! It'll give me better reliability, improved access, expandabilty, and a neater engine bay. Sounds like a win-win to me.

This is the Fuel Injection and Sensor Harness:

ALL of the plastic connector housings that plug on to the individual fuel injectors are broken. They've been in a very hostile environment for 39 years, and have given up the ghost. They crumble very easily and need to be replaced. Parts are readily available, and come in pig-tail form, or loose parts. All the non-adhesive vinyl wrapping tape is hard and brittle, so I'm going to get that off, inspect and clean the individual wires, and re-wrap it with new, better quality tape.

Here's a closer look:

And this is the Everything Else harness:

All these connectors will get cleaned with DeoxIT, and then given a shot of silicone grease before re-mating them. This vinyl wrap will also get replaced, and the wires wiped down before being re-wrapped.

Tedious work, but the engine bay will sparkle when it's done!
