Today's patient is Yashica Minister D from 1964 with non-working light meter. Mechanically this works well!

Oh, easy! A wire was loose from the metering button and button contacts needed contact cleaner.

Light meter now works and numbers are reasonable compared to light meter app on my phone.

Like my RF-pilkki (RF-rod) for 20m band? 😁

"New" for me. I bought it second hand.

Testing ATU-100 with FT-450 and vertical EFHW. Auto tune seems to work well. It has no memory, so it's tuning on every band change.

It tunes down to 80m band, but 160m it a bit too much! I have no 40m/80m "extras" on my vertical.

But, again, build quality, fugly as fuck! It needs some rework!

Finally the first QSO with my "RF-Pilkki" (RF ice fishing rod)!

Very easy to reel wire out for proper length for EFHW.

Also testing a very, very cheap ATU-100. Build quality is awful, but seems to work. G90 does not need it, but maybe it helps FT-450 in some cases?

Sooo, it seems X-37B OTV-8 is coming up August 21st, on a Falcon 9 from KSC designated USSF-36, analysis on which vehicle will fly on-going as they are playing games with the published image resolution ;-)

Something special: 1982 Minox 35 PL with an optional flash unit! Very tiny full frame camera. Film canister for scale.

Looks like it works fine, too!

This was a bit more: 50 euros after "twisting my old hand and putting my family to the streets..." -kind of haggle πŸ˜…

Today's outdoor flea market finds:

Pristine condition Olympus OM10 with 75-150mm/f4 lens. Sold as non-working condition. 25 euros after a haggle. New batteries in and works just fine!

I found a perfect match for my "America's Man in Space" View-Master reel set!

I've never seen a View-Master like this!

I am very happy with this setup! With the HF vertical I have had FT8 contacts to Japan, Brazil and Australia and SSB QSO to France!

Diamond X30 helps my now reach new repeaters. I have Anytone AT-D878UV Plus II (mouthfull!) connected to it, some times Icom IC-R30 or Airspy for RX only.

Xiegu G90 tunes all bands and Yaesu FT-450 almost all.

New Diamond X30 is for 2m/70cm bands and an old ADSB antenna feeds Rasperry Pi and Flightaware stick just five meters away (PoE powered) instead of 15 meters of cable it used to be!

Spare LAN cable is for future use (a meteor camera, perhaps?)

#3 Antenna upgrades!

I finally have something permanent for HF bands!

I acquired a permit from my lovely neighbours to install an additional vertical antenna. It is Sigma Eurocomm SE HF-360 for 6 to 80 meters. Being only 5.5m tall, it is not an eyesore.

DIY "hat" connects relays and sensors. The box sits on "legs" which has strong magnets to "clamp" on a metal surface on the roof.

The view is superb! 42m above ground, 83m above sea level! 360 degree clear view!

The camera sits in an enclosure and has a heated dome. Three temperature sensors (dome, enclosure, outside), humidity sensor, two relays for controlling the heaters ( 1/2 and full power).

The RasPi boots from a SSD drive. Software is from github.com/AllskyTeam/a...

#2 Allsky Camera!

Our radio club has a repeater site at the top of a tall apartment building and my suggestion about a allsky camera was greeted with positive feedback! I bought a Raspberry Pi 4 and a fisheye lens, but rest was "bonk" and donations.

I also made simple website for our neighbours to check out. Unfortunately no nesting this time, only random bugs.

But three other had inhabitants! Great Tit, Blue Tit and European pied flycatcher had several babies!

Quite a bit backlog of finished projects to report of... Short thread to follow.

#1 Nest camera for a birdhouse

Earlier this year I cleaned three bridhouses and installed fourth one, which has a camera and temperature sensor in it.

P.S.

This is exactly the reason why we (read Europe) needs an independent system of publicly available orbital location data.

Today's fleamarket find: "America's Man in Space". three View-Master reels, 21 "stereo pictures" from 1962!

Who needs VR when you have crisp and clear "stereo pictures"!
