Working on 8mm film projectors

I’ve got some old 8mm film from my father. And i wanted to digitise them.
Luckily he had some projectors. One was his own and a borrowed one.
Don’t know about the third one.

Not being used for 30+ years, none of them worked.

So i took them apart and tried to fix them.

Most of them had a driving belt issue, and two of them needed a new bulb.

In the end I had three working projectors. Let the digitising begin!

I started off with putting a Nikon camera beside it and selecting 24 frames/second and putting the speed dial just right .. i got a decent recording.

Tips:

Most drive belts still can be bought, sometimes you have to search for an alternative with same dimensions.

Measure the resistance of the power connector. The old transformers could have a shorted connection. (cause: dried out insulation of copper wires)

Use a pressurized can of air to clean the insides.

Keep track of the parts when disassembling. Those things are not made to be easy fixed.

Below a uncut/unaltered recording, so the media needs some cropping!
I love the authentic shutter sound!

Old computer : Comx-35

Trying to fix a computer from my computer collection.

Comx-35 (1983)
  • RCA 1802 CPU @ 2.8 Mhz
  • 32K Memory

Apparenty something wrong with the graphics chip.

The COMX uses the RCA CDP1869 and CDP1870 Video Interface System (VIS), consisting of the CDP1869 address and sound generator and the CDP1870 colour video generator.

Maybe next to try : checking signals using a Logic Analyzer

Looking for the building in Revenge of the Ninja

When I was young I studied several Martial Arts.
Ninjutsu was one of them.

( Monique had a workshop from Masaaki “okay lets play” Hatsumi )

One of the two places i studied Ninpo

Ninjutsu (忍術), sometimes used interchangeably with the modern term ninpō (忍法), is the martial art strategy and tactics practised by the ninja.

I alway liked the movie “Revenge of the Ninja”.
I like Sho Kosugi

Well .. didn´t want to go to bed. Lets try to find the building where they are fighting on the roof.


Found it!

Sun in the stream on my Uilleann Pipes

Irmgard told me a week ago she liked “Sun in the stream” by Enya.
I found a midi file a while ago, which i edited to get the accompaniment part only, without the melody line.

I played this after 4 times practicing, and learning to use some extra keys on the chanter while doing so.

I played the midi file on my Yamaha QY-100 sequencer.

Merry xmas and a happy 2018

Making some steampunk lighting

Some new lights in our livingroom.

A while ago, I made a wooden shelf thingy behind our couch.
Inserted some electrical outlets and some network ports (utp outlets)
Put a load of little pebbles on top. But it needed some light.

Get some copper tubing, a pressure gauge, tap, bends and some electrical wiring.

First design

Easy and lots of fun

Welding course

Over a period of a few weeks i did a welding course, where i learned to weld with : Mig, Tig, Stick and Gas

I only did point welding, way back in school.

After the course i decided to buy a stick welder.

Beer hops

My DIY hop stirrer!

Because we brew our own beer, it was a no-brainer to grow our own hops.
Well … it sure grows .. and fast!

On several occations we made beer with it, but not knowing which type of Hops they were .. it was hard to do the calculations!

Beer brewing foam blow out!

XML not retrieved: cURL error 28: Operation timed out after 5000 milliseconds with 0 bytes received

Sometime the yeast fermentation is TO active.

Resulting in a blowout. Blowing air into to brew is automated by my brew computer. So i didn’t check myself meanwhile .. Maybe somekind of overspilling sensor can be made??

Beer in this yeast container was a Rauchbeer / smoke beer
