Panasonic WJ-AVE-3 bending? (and a video enhancer) (+video)

Author Panasonic WJ-AVE-3 bending? (and a video enhancer) (+video)
flx
I just got a cheap AVE-3, which is in super great condition and I found Karl Klomp's website on bending it:

http://karlklomp.nl/inf/ave3.html

I've never soldered SMD parts before and I'm a little bit scared that I'll break the device. I would also need a better soldering iron for those tiny spots I think. Are there other points which aren't SMD that I can use to attach the wires?

Also, did I understand it correctly that I just have to connect the one sync point to all buffer pins and put push buttons on all the wires? I've seen some pictures online with banana jack sockets, but I assume those were from more advanced bending projects.

Here are some pictures from my Instagram account by the way, on which I post my video glitch stuff.

you can use the pins of the memory ic on the bottom side of the pcb to make the connections (which are through hole pins) just don't heat them up for too long.
you can use a ribbon cable for that.

just try connecing them to ground or the sync point or each other first and remember the usefull connections. later solder switches or build a patch matrix.

you can also experiment with using other 5v signals you can get from somewhere on the pcb, something like a 555 oscillator or audio signals.

besides karl klomp there is also this site: /http://lushprojects.com/videobend/ with some information on panasonic ave bending.

also be sure to check the service manual.

i also suggest getting a ave5 or ave7 if you find it cheap. it's even more fun than the ave3 for bending (2 channels) while using the same hardware concept and memory ic.
[edit: just remembered that this is only true for ave5. ave7 has in fact 100% smd components and is harder to bend]

Thanks for the replies smile I actually got an AVE7 shortly after the AVE3. I'll see about bending that AVE3 then.

have fun with the ave3 then!

had a look in the service manual again. these are the pins of the memory ic that you might want to stay away from:
pin 28: 5v (don't ground that!)
pin 1, 26: ground (you can take ground from here, but it is not interesting by itself.)
pin 27: output enable
everything else is potentially good for bending (data in/out, adress in and in/out clock)

Thanks for looking that up!!!! I have to find that manual some time. I just soldered wires to various pins and found the GND, but luckily not the 5V. Phew! woah

It was a lot easier than I thought it was, although I had two bigs scares. The very first time I connected power to the AVE3 it wouldn't power up ... turned out that I forgot to attach the power PCB's ribbon cable d'oh! After that everything went as expected until the fourth time, at which I didn't get any video signals ... because I forgot to plug in the input socket PCB's ribbon cable. It's motherfucking bacon yo

Here's a short video demo of where I'll leave the bending for now:

Now I just have to get my drill back so that I can attach those switches to the housing.

THANKS A LOT FOR THE TIPS!!!!! we're not worthy

I also bent a Hama VS-2 E III video enhancer today, which was fun and easy. It has a bunch of internal calibration trimmers, which I could tweak and use as solder points. Here's a demo (of course wink ):

great. applause

have you tried the bent ave3 in a feedback loop?

Thanks smile Haven't tried that yet, but here's this week's jam session video, which includes a VJ performance with some of my gear:

Nice work, we have been trying to get a WJ-XXXX to bend for some time but they seem to be popular lately on the bay. I have never had the guts to splash out on something I just want to bend.

Here is a kinda amateur promo vid we made for Form Constants, our setup has changed a bit now but the idea remains:

Good stuff! I only bent those things because they were so cheap, although I was a bit scared about the AVE3. It was really easy though in the end, thanks to the tips from earlier thumbs up

Here are some bending pictures, by the way:

hi! tha HAMA AV PROCESSOR 122 are very good for bending!!

oooopss here a demo!
