I have tried repainting the headlight arms, I used brake caliper paint. A bit of a shoddy job on my part but it looks much better now, new wipers too. I think this is a really useful feature for winter driving. Sure I don't drive this in winter but still...

Image

Image

I also added an extra washer pump in series with the original one (new one near the headlight)
Image

Much more powerful now, also replaced the right hand washer nozzle with a dual stream one, from factory it was only a single. Why I dunno. Now it really hoses down the windshield.

That SAAB looks really nice. Always been a Volvo man myself. I once had a mint green Volvo 740, like your mother likes. :)

Thanks, it was in good shape when I got it but I've changed so many parts on it already and I got years of work left too. I'm trying to bring it to nearly new condition. My mother isn't a volvo person though, they're all about Mazdas. Now I wouldn't mind an old volvo actually, a 245 or maybe a 745 or 945. They're a bit fuel hungry however...

I removed the inside door panel on the left rear door last night. Wanted to check what it looks like inside. I will want to go through all the doors like this.

Image

This is behind the door handle is screwed on, it has started to rust. Suspect water ingress through the screw hole and no rust proofing in the thread. I brushed it over with linseed oil. At some point I'll probably blast and epoxy prime this spot. Also a good idea to remove the handle and put some sort of sealant there.

Image

The bottom inside of the door, don't know if I see rust there n the corner, or if it's the wax. But I spray linseed oil here too. I also used a small brush to get linseed oil in a bunch of seams. It'll penetrate into the seams, do it's antirust thing and oxidize, swelling and sealing the seams from further water ingress.

Image

Every damn time I open the door he goes in, don't know why he loves the Saab, don't do this with any other car.

Less positive news, rust hole in bottom, drivers side footwell:
Image

Feels pretty localized though. Gonna have to rip out the interior mats and weld it from above.

Seat belt lock for drivers side stopped latching too, so I had to remove that as well and get a replacement. Might as well get the seat out.

Image

Image

Looked under the carpet and there it is:
Image

I am gonna try and ignore it for now... sprayed linseed oil on it and then put thick oily crap over it. Maybe I'll have time to fix it towards autumn. Got other things to think of right now.

Something less car-ish, but it's actually still related. It's a car phone! Made in the late 80s and for the NMT network. That's an analog 1g network that was what we had before GSM. I remember reading that the nordic countries had the most extensive networks and most amount of mobile phones in the world back in the 80s thanks to Nokia and NMT.

NMT used 450mhz and later 900mhz, the earlier 450mhz gave lots of range when combined with the 15W transmitter that those phones had.

They didn't shut the NMT network down in iceland until the 2010s and it still exists somewhere in siberia!!! That's incredible to me.

Picked up this phone last night, Nokia Mobira Talkman, this one is likely a 900mhz version:
Image

Doesn't specify what Talkman it is, just looks like a 520, this is the designation on the phone:
Image

Image

15 pin serial connector, unsure what it's purpose is.
Image

The phone handset
Image

It uses an RJ45 connector, with it's own color code, I assume it uses serial communication:
Image

No charger though. Needs 12V though and likely several amps.

I'm not sure what I want to do with it, except I want it to work, I want it to live!

There are two ways to go about it, either rip out the guts and replace it with something modern like just make it into a bluetooth set for a modern phone, or the more complicated option. Build an NMT base station simulator, funnily enough there's software for that (and other analog networks) and then connect that to something modern:
http://osmocom-analog.eversberg.eu/

Of course this latter option appeals to me. Just the idea of using that old circuitry and going analog even if only for a short hop to a base station that's a meter away. See what I really want is to install this in my Saab and have it work, ideall with it's own working phone number.

I also want to install in this car it's own 4G modem / router with it's own sim card to make use of the 900mhz antenna on the roof so I can have good wifi out here in the sticks, I lose connection now and then with just my phones built in antenna.

So I got this crazy idea of this phone mounted in the front and in the trunk I have a raspberry pi server or something running osmocom-analog and an asterisk PBX with the required hardware. The sim cards phone number would be the cars phone number and direct to the old phone.

It would be cool, not sure I can make it work. Biggest hurdle is an SDR transceiver, they are not cheap even if they have gone down massively in price. Then I really gotta figure out telephony systems it's all very hard right now because I don't really know how VoLTE and telephony stuff is routed. But give it a few years maybe I'll learn this stuff, maybe I'll loose interest and give up (more likely).

Been doing more research on the possibility of resurrecting my NMT phone and things look brighter. I should be able to tie everything together the way I want using:

-SDR-Lime Mini transceiver
-Raspberry Pi
-4G Dongle with sim card
-Asterisk PBX server and Osmocom-Analog running on the raspberry

It looked like for a while I was screwed or not able to do this the way I wanted. The key was being able to use a USB dongle, so that Asterisk can call out from it using the sim card, and calls to the sim card can be routed to where I want them. Being able to do this with some cellular gateway was looking complicated, expensive and bulky.

Asterisk had 3rd party support for 3G USB dongles via "chan_dongle" but the project was abandoned in 2016 and they're closing 3G down soon. 4G is a requirement. Fortunately someone else resurrected the project in 2022 and there are versions now that work with 4G usb dongles. So yes it's back on the table!

Also a good link for anyone who cares about old analog cellular:

I bought my first SDR too which is called "RTL-SDR-V4" to get some SDR experience and it's pretty cool, plugging it into my PC I've been able to look at frequencies from 1 KHz to 1 GHz, been able to tune in 4G digital signals, shortwave radio, HAM radio transmissions, FM radio and other kinds of signals.

In other news I almost got my 4 weeks of summer vacation coming up. Here's what I got planned for my vacation. Got approval from the municipality as well, even though the plans are not 100%

Image

I need double the rows of plinths compared to what is shown here. I hadn't drawn them in at the time because I wasn't sure what style I'd go for.

Image

I started to dig two holes and what a PITA. The first hole went well, it was close to the house. Topsoil at the top and then gravel as far as I could dig, the real issue here was getting the soil out. A shovel once you get deep enough isn't a good tool, need some kind of scoop or a wide hoe to get the soil out.

Image

The second hole further out, pure nightmare stuff. Rocks rocks and mud that was as hard as rocks...

And then I reached a hard stop... Either a huge stone that seems to be as big as the entire bottom of the hole, the stone is also there in the upper corner where it was possible to dig a little deeper before you hit it again. I'm beginning to suspect it's the bedrock which means it's that rock about 30-40 km down before you reach lava...

The bedrock always close on this lot, exposed in placed and we had to blast to get the foundation for the house down. If so that's probably as far down as I'll be able to go. But if it's bedrock then at least frost heaving won't be an issue. It's not deep enough to use the plinths I planned to buy however so that's another annoyance.

Image

Image

I gave up on doing this with manual labor and called in a digger.

Digger dude came and uprooted my yard last night. Took an hour or less than. There were so many large rocks, some he rolled off towards the trees that where hundreds of kilos... I realized doing this by hand would have been a fools errand. Just moving away all the soil is toil enough.

That thing I thought was bedrock was just a rock, but bedrock was just under it. About 1 meter on average to the bedrock.

Image

Image

My plan is now to buy these round paper forms and cast my own plinths, and I want to drill and sink the rebar into the bedrock.


It's been a shitty weekend Saab-wise, I got gas smells when I filled up the tank too much, I confirmed a leak around the o-ring seal that holds the whole pump in place. Well the o-ring didn't get replaced as the replacement I bought was the wrong size (internet led me wrong here), I forced the old one back in and I found out I'd broken the fuel pump by removing it. More precisely the plastic hose barb on the inside of the assembly broke off, that's where the fuel goes from the pump and out to the fuel line and to the engine, so when I started the car fuel just splashed about inside the fuel tank and went nowhere.

I have the original 34 year old fuel pump assembly left and what I did was I scavenged the parts from both assemblies and was able to build one working fuel pump assembly from these. The OEM one seems to be a lot more durable than the modern repro... 34 years of technological progress and they can't build a part that lasts. Or they don't want to...

Anyway this was a whole lot of work just to stand in place, or possibly even a step back as I bet the o-ring seals even worse now.

I bought plastic pipe to use as plinth forms. I figured they would have paper ones, but they offered these plastic underground pipes instead as plinth forms. *shrugs* Why not I guess, these are much more sturdy and I won't have to worry about the paper dissolving from ground moisture. So I can bury and align everything and not having any stress about it.

Image

I got a laser level but still find myself using a lot of string, just makes it easy to see. Laser is good for double checking.

Image

All six are down and aligned, the outermost ones I've cast feet straight into the ground for as the roof pillars will rest on those. They are also aligned differently, the inner ones will come lower down.

Image

Image

The last one took me a while because two large frogs had jumped down the hole and were stuck there it seemed, so I had to try and fish them out so I could carry them off to the woods. Would be pretty cruel to just cast concrete over them. I guess they were looking for moisture as it was 29C outside and pretty dry. Hosed them off and put them in dense foliage in the woods where it should be wetter.

And all the holes filled back in. My back... And still got a lot of soil and grass we need to move away, got some spots elsewhere that could use it.

Image

First load of lumber, they didn't have everything I needed so I'm gonna have to come back later for that. But I got the material for the posts (48x148mm planed and treated, that's about 2x6") and related material.

Image

Thanks, it's my daily driver during the summer half year. Love 900s, so nicely designed. This one was made in Uusikaupunki too.

I started today on attaching the support beam to the house foundation.
Image

I got concrete screws I will screw into the wall using CC-600mm layout. So I scribed a buncha lines 600mm apart on the beam and drilled holes.

I used a router with brad point drill bit to make the holes. Because I don't have a portable drill stand. This worked real well when I ran the router on the lowest speed, it was about as fast as a drill going full tilt.
Image

I got the beam temporarily mounted, aligned with the previous deck and then leveled. Then I predrilled a little in each hole with the concrete drill.

This is the drill I used because my makitas hammer drill mode is broken. I got it from my dad and I think it's from the 80s.
Image

Then start screwing the beam in place
Image

There, done:
Image

And the final delivery of lumber dimensions happened so I could start assembling things! But the last couple of days were wasted which had good weather and now we got shitty rain going on and off. But I got three posts up now anyway and the plinths are levelled.

Image

Next I need some 48x123mm (about 2x5") to install between the sandwich posts to stiffen it up in one direction and then I'll start putting up the "floor joists" between the wall and posts, once that is done I can more rigidly fix the posts in the remaining direction and start putting the top beam on.

Image

And yeah these bits aren't treated. I cheaped out and didn't think they need to be treated, they will get painted white and be under a roof when done.

Image

Things are starting to get messy. Also I really hate the boards on our current deck. 28x128mm I believe they might be and they have these annoying grooves in them that catch water and crap. For the new deck I will go with much wider boards, 28x145mm or even 34x145mm boards and they will be smooth. Not decided if I should buy from the local saw mill or get pressure treated boards. You can see the boards are getting twisted too from the sun. Mistakes were made assembling them.

Image

The new decking will look something like this with a few boards going the other way to cut up the uniformity and allow me to use shorter lengths, I can setup the miter saw to just cut one length over and over again to boot:

Some progress, got the top rails installed. I made it needlessly complicated but looks a little better like this.

Image

Image

Started installing the cross beams (2x5s)

Image

They're all one variation or another of bendy banana, infuriating as hell! So I'm going over them with this spacer that's 552mm wide (gives you C-C 600mm with this lumber) and clamping stuff together and screwing it down to the support below.

I still think I will need to cut and screw a bunch of braces between the beams to keep them from bending sideways too much. Particularly at the opposite end near the wall.

Image

The level and that piece of aluminium extrusion is an important piece for going over everything and checking that everything is level.

Image

Floor beams are mostly done. I got the roof beam up as well.

Image

Image

Evening
Image

Morning, deck faces east so will get morning sun.

Image

These rails are solid as hell I tell you what.

Some of my tooling used for the majority of the work. I've done most cuts on the circular saw. I got a miter saw with a stand but the stand doesn't easily move outside and is not water proof. Hitachi C6BU saw cost me 25 euros 8 years ago. Great saw.

Image

Once I cut the roof beam profile I go over it with my plane which has a nifty underside since I used it for cast iron scraping practice, one of the flattest planes ever I would think.
Image


All the roof beams are up

Image

Image

Nice view
Image

There's the shed too which started the thread.

Image

Where it meets the roofline of the house, it's gonna be tight but I measured it and it will fit! So I am fully prepared for it not to fit when time comes to put up the roof. I will need to paint it before assembling the roof as well.

Image

Been having some nice weather until today when rain ruined my day.
