The Owner Manual of the Cadet I Sync Generator is available from the LZX website!!

https://www.lzxindustries.net/documenta ... M-V1.0.pdf

This answers a lot of question!
-About how to patch incoming external signals so that they sync with the video synth
-Basic info on Genlock
-How to connect the sync (flatcables) on the back of the modules.
and much more.

The manual is written very clearly and describes the functions of all elements of the PCB.

Awesome! :sb:

Could a cadet sync generator be used to create sync for Expedition series modules?

does anyone have any of the switches needed for the Sync Gen?
Mouser are out... I only need one
http://www.mouser.co.uk/Search/ProductD ... key10TF230

Alternatively, I'm going to hardwire this as I wont be using any NTSC stuff...
'could still do with some of these switches as I notice they are needed for the VCO...
anyone got three (i haven't got the PCB or anything, though, just thinking ahead)?

did anyone ever figure out where to buy these individual switches? as the moq is 100. need a couple for the vco pcbs im about to buy. couldnt find anything on mouser that was comparable enough right angle wise.

but i did find these, which should do the trick although they arent right angle. i think the thread width is the same if the hole on the vco panels are similar to the processors panel. strange the datasheet for the 10TF230 doesnt have a thread width or panel mounting drill dimensions.

108-0042-EVX

only place i could find the right part online was some place called swatee electronics. which i think is in the czech republic. but that doesnt really help me as im in chicago... but could help some other wigglers out that way.

I just finished my first Cadet! The Cadet IX VCO build was straight forward and works well with sync from my Visual Cortex.

I used this switch for sync. It seems to be very close to the Mountain 10TF230 switch in the BOM. It works fine and looks fine with the other switch but does not sit flush with the PCB when you solder it in.

cool! I've been tempted by the oscillators but I am running out of rack space. Post some demos when you can!

First tests of the sync generator + video input + rgb encoder were succesfull!
(mostly)

I have to check the contrast pot, because that seemed to do nothing.
For the rest all sync signals are present, all color / luma outputs work and video was passed through.

Awesome!

update: finished + tested the Ramps module, shapes and colors :goo:

now to make cool panels!
I've chosen to use banana's for patching and BNC for video in+outputs
pictures will follow soon :sb:

No patch? Otherwise it looks like the order I am putting in except I am waiting for them above X pcb:s as well. :bananaguitar:

patch is a misleading term :hihi:

no I did not get it with the system 21 order.
but i'll order more soon i guess, with the 5 upcoming new cadet modules / pcb's, then i'll add it !!

I had a 2u hole in my video case so I stuffed 16 Cadet boards in a blank panel:
3 video inputs
3 keyers
3 faders
3 multipliers
2 scalers
2 VCOs

I've just tested the first VCO, Works too!!

I've found a lot of awesome knobs on an old mixer.
very large, but colorful and vintage.
Downside is that I have to wire everything. Oh well
(or else the knobs won't fit, the pots would be too close together)

I have built 4 or 5 different modules so far and they have all been fun builds. Also, many of the same values of resistors and caps are used over and over, so if you buy a bag of a parts, you can use them across just about all of the modules. Really nice modules to build. In the middle of putting together a little LCD module for the rack, so I should be able to start making some images soon.

I just found this on the LZX VI Fader assembly notes:

"We recommend you avoid socketing the ICs. Capacitance in the sockets can affect higher bandwidth circuitry more than it would in audio applications."

I added sockets to my VCO builds. Does anyone have any insight? Should I try to remove the sockets from my build? How would a capacitance problem behave?

mh. I missed this too.


Let's ask the developers then. I'll email Lars

reply:
IC sockets add capacitance to the connections to the pins in the circuit.
It could potentially limit bandwidth or add ringing/oscillation to the circuit.
In practical terms, if everything looks good to you, you probably don't have to worry.
But if you see any strange noise or ringing, that could be the source.

Some are awaiting rework - Lars didn't have a date last I spoke with him, but feel free to reach out to him and ask!

with the cadet scaler, do i basically just want a bunch of 5v to 1v if i would like to use my audio modules with the video stuff?
