Oh, and in case you're interested, the military vehicle show that featured in many of the photos is "Wartime In The Vale" which takes place in Evesham UK every year - it's very good, and you don't have to be a military enthusiast, just having an interest in old stuff will do.

The FR1 was introduced somewhere around 1977 and features an electronically controlled shutter and a good metering system, the Contax/Yashica bayonet lenses tend to be cheaper than many other systems these days, making it quite an attractive proposition.
There seems to be one common failure with the FR1 - the frame counter, which suffers from a split nylon gear. I show a little of how I repaired this during the video, but you could use the camera without a functioning counter just the same.
Here's a link to my previous video looking at Kodak Vision 3 500T film:

The Lensbaby 3G was the third generation of Lensbaby, still essentially a lens mounted on a bit of flexible pipe, but with the addition of some locking rods so you could hold your focus and bend while using the lens on a tripod. I think Lensbaby revisited the general design of the 3G when they introduced the Control Freak a few years later - I think the Control Freak uses the optic swap system lenses, as found in the Lensbaby Composer, but from what I can see, even the Control Freak has been dropped now.

Harman are better known for producing Ilford Black & White films, but they also already make Kentmere Black & White under the Harman brand, so the new Phoenix film sits nicely along side that.
Harman say the film can be shot anywhere between 100 and 400 ISO, but the box speed is set at 200 ISO. I opted to shoot my film at 100 ISO to avoid muddy shadow areas as much as possible.

Although it might seem like I'm not happy with my Kiev 4, I think I probably just had over inflated expectations having seen many people sing it's praises, and it just didn't quite live up to the hype, but having filmed this video I'm all eager to try it again - I've quadruple checked for light leaks, tweaked the rangefinder yet again and will hopefully head out with it again soon, at least as soon as I've finished some of the 15 or so films that I currently have in other vintage cameras.
Film used: Ilford FP4 shot at box speed (125 ISO)

The Bee Meter was invented by Alfred Watkins in the late 1800s, and continued in production until electronic meters took over. The Bee Meter uses light sensitive paper to measure the strength of the light - even in bright sunlight it will take a few seconds to darken to the same shade as a control strip next to the test strip in the measuring window - by counting how many seconds it takes and applying that figure to the exposure calculation dials, you can quickly (well relatively quickly for the time anyway) and accurately measure the correct shutter speed to set on your camera.

As with much military equipment, this periscope was designed to be solid and easy to service, with simple latches to remove and replace the mirror sections, and a single knurled knob to attach it to the bracket in the tank - no special tools required.
Addendum: There were a couple of things puzzling me while I was shooting this video, one thing was the end that I "thought" was the top, slotted inside the body of the unit, whereas the end that I "thought" was the bottom, had a flange that overlapped the body - it would make much more sense if the unit was the other way round, with the overlapping mirror unit exposed to the outside to stop water penetrating. The second thing was the handle that someone told me hooked over some sort of bar - looking again, I think this is purely a handle, and the whole unit is pulled downwards into the tank and a replacement pushed back up into the bracket and locked in place with the knurled knob. So when you watch the video, just visualise the whole think the other way round and it'll all make more sense.

When I first uploaded this video, a regular viewer pointed out that the zinc air cells can produce quite a bit of gas (Hydrogen), which could potentially cause a problem if they were sealed inside the casing of the meter (I've since added a section to the video and re-uploaded it) - I suspect once the pressure had built up, the big seal round the front glass (plastic) would move slightly and let the pressure escape (that seal being designed to withstand inward water pressure not a build up of gas from inside the unit), but it would probably be wise to remove the battery from this meter after use, or, if you're not using it for diving, leave the "O" ring out when you fit the battery hatch. I'll put a link to one of Big Clive's videos below, where he does some experiments with zinc air batteries and the gas they produce.

The Canonet was introduced in 1961 with the first version (like mine) having a Selenium cell exposure meter and no indication of the selected aperture in the viewfinder. Versions of the Canonet continued to be produced right into the early 80s.

I really enjoyed using the IC-1 Auto, so much so, so much so that I broke my golden rule of only shooting one film before examining the results - as it happens, one of the shutter curtains is dragging a little bit, so I will be doing a full strip down once I've finished the current roll of film, luckily it's not too serious, and the shots are more or less fine.

The Edixa Reflex features a removable viewfinder, giving the choice of a prism or a waist level viewfinder as seen on my example. The lens mount is the pretty common M42 screw mount, my example being fitted with a 50mm Steinheil Munchen Cassar S f2.8
There were a few repairs to do on this camera when I first got it - I'll briefly cover these, but this isn't a repair video as such.
Film used in the Edixa: Ilford FP4 125 ISO

In part two, the engine sort of ran, briefly, before the coil gave up completely and there was no spart at all. This time round I'll unwind the secondary winding from the coil and rewind it using a home made coil winding machine. Then I'll run the engine for the first time since the rebuild and check the generator is functioning before leaving you with a bit of commentary free engine running footage.
The coil rewind is far from perfect and I could definitely do better if I had to do it a second time. I doubt for one second that this coil is going to last as long as the original, which was completely sealed from the outside world having been dipped in shellac (or similar). That said, the sealing had failed and moisture had managed to make it's way inside, so maybe mine will actually last longer than I think.

Firstly we'll get the flywheel off in order to clean the points, and replace a missing insulator before finally getting a fairly weak spark - it was quickly discovered that the secondary winding on the magneto coil was "open circuit" so, although we do have a spark and the engine might run for now, ultimately, the coil will need to be rewound.
After that, a large amount of time was spent pulling the engine starter rope, with so many "almost started" moments, but eventually the coil gave up completely and that was that.
While we wait for the wire for rewinding the coil to arrive, I fabricated a silencer to go on the end of the flexible exhaust hose.

The calculator was in a pretty bad state when I got it, the case was badly damaged, the circuit boards were filthy and some (most) of the capacitors were reading incorrect values. Once everything was cleaned, some components replaced and the case repaired, the calculator started playing up - the problem eventually being traced to a bad via on the keyboard PCB.

As is fairly normal, the calculator didn't work, the vacuum fluorescent display tubes just showed a load of decimal points and the three warning lights were illuminated. After much testing, we discovered that the calculator was actually running - when you entered 17 digits the calculator would overflow, requiring the clear key to be pressed. After that we discovered that you could read the contents of the main register and memory using an oscilloscope, it was in binary coded decimal or BCD format, but it was there all the same. So the problem lies with the display driver section, from what we can tell, the issue is with the HD3233P chip - I have a random PCB on order containing some of those chips, so hopefully the problem will be solved when we replace said chip. If however the problem is actually the HD3253P chip, then that's not so good, because I can't find any of those anywhere......yet.

My CW-20 didn't work when I first got it - initially the LCD screen displayed "RAM Dead: Reset" and after a little searching, I found out that this can happen after the batteries have been changed. The reset procedure appears to be turning the typewriter on whilst holding the CMD and Margin Release keys. Once that error was cleared, most of the keyboard didn't work - this turned out to be a damaged ribbon cable on the keyboard membrane, along with dirty key contacts on the membrane itself. Once all that was sorted the typewriter worked perfectly (I did take it apart again and now the Tab Set key and the letter "S" work as they should do).

Hewlett Packard made a series of very powerful calculators in the 1970s, including the HP 97 and it's pocket sized sibling, the HP 67 - both machines used magnetic cards to store data when the machine was powered down.
My Elektronika MC 1103 was a much later calculator, made in the Soiviet Union in 1990. The MC 1103 has some fairly advanced external connectivity, to measure data and receive signals from other equipment.
At the time of filming, neither machine is working - hopefully I'll make some progress and release further videos featuring these two machines. If and when I do, I'll put links below:

In the video, we'll go over the basic functions, including using constant multiplication and division, percentages and memories, before looking at how to use the 8 program modes on the Borroughs electronic calculator.
In the previous 2 videos, we looked at, and repaired, the Shinshu Seiki EP-102 printer from this machine - links below:

There will also be a future episode when I demonstrate the Burroughs C6202 calculator itself. I'll put a link to that video here once it's done.

The EP-102 was the successor to the EP-101, made in Japan by Shinshu Seiki, a subsidiary of Suwa Seikosha. Shinshu Seiki went on to become Epson in the 1980s, the name apparently coming from a later incarnation of this printer EP-SON.

Gear Specifications:
0.4 Module
Small gear 17 teeth
Large gear 68 teeth
Overall width of original gear 7.2mm, although replacements were both 3mm wide so it only came to 6mm, the difference being made up by creating a longer sleeve to join the two new gears.
The replacement gears came from HPC Gears in the UK.

In the video we'll take a look at the failed gear and also show the rather ingenious way the printer hammers are synchronised with the revolving drum, then hopefully there will be a follow up video soon, once I've cobbled together a replacement gear. I'll put a link below once that video is released.

The 1214P is a printing calculator with a 12 digit capacity and some relatively advanced and user friendly features for the time.
In the video we'll look at what features the calculator has along with the age old question "what happens if you divide by zero", and finally we'll take a look at the inside of the machine.

The Sterlicon was very well made, and cost £6/19/6 (six pounds nineteen shillings and six pence) which equated to £6.97 1/2 in the new decimal currency.

Since filming this video I might have figured out the "5" in the name - the Sterlicon calculates the pound 5 decimal places, so that may well be the reason for the "5" in the name.
