VCR Recoder repair

Hello John Mason:

I really may need a bit more info, type of VCR, model etc. But I searched for:

what is the voltage and wattage for a lamp in VCR recorder

And got this back. Check it and see if your model is on the first couple of pages, or let me know the model, etc.

Good luck and take care.............

Hi

It' the tape end infrared diode i have sourced one without it working everything locks up

Thanks for your help

Best wishes John M

Hello John,

You found it to be this diode, but can I ask where you sourced the new one? Was it from an old machine?

I hope you continue to be a member, as you seem to know your way round an electronics board!

Take care and have a great new year!

Hi

Nice to hear from you in my request for help i have another vcr which has gone down and i suspect it is for the same reason . One i can fix the other is a a Goodmans it's a lamp that shines through the tape onto a photo receptor and signals the position of the tape so that it doesent get snarled up if this piece of the setup is not working then all the control buttons lock. Now i sourced the spare from Maplins a UK company an infrared emmitting diode bet i have spelt that wrong Any way the original control lamp was an ordinary tungsten miniature bulb i suppose things have moved along a while since i bought this recorder but i heard that the photo cell employed was infrared sensitive so a dedicated diode might work better

Many Thanks All The Best John M

Hello John,

Sounds as if you have it all sorted and know enough about what you are doing to try alternatives. That shows knowledge.

Hey, do not worry abut the smeling I afton mak misteks! Least I can understand you. That is half the battle!

The info' in the lamps will help at least one person I have been trying to help. Their name is taankk and they are doing an art project. They want to have 9 chairs with diodes (my suggestion) which sends a signal to her computer, which is with her a few metres away behind some curtains. That then sends a signal to a projector which charges the picture on a screen each time someone sits in a chair. To be fair there is others helping as well but, we are stuck. She can't figure out how to get the photo-diodes to send a wireless signal to the computer.

I found some tiny touch sensors which will be under a pillow or material on the chair. My suggestion was to have the sensors wired to a tine loud speaker which made a noise above 20 Hz. That way no one would hear it and it would some here switch something on the computer which turned on the next film clip. But all this has to has withing a few seconds and whoever sat down last, it is that clip which stays on the longest. These happens for as long as there is people to sit in the chairs.

Do you have any ideas about how they can :

1) get the signal to the computer wirelessly. And,

2) how to use the computer as a switch to turn the various film clips on?

I will leave it with you.

If you do think of anything she said she was going to try a new thread on the computer programming section of this site. But the details of what she has done with our help, so far is on the Engineering page.

The sensors are either photo-diodes or touch sensors. They know nothing about photo-diodes but it may be the cheapest was to communicate with the computer?

Take care and a huge thank you for your reply post!

Great new year OK?

Hi

I suggest that you buy a cheap 2 channel radio control transmitter and reciever and a computer mouse that you no longer have any use .

Get some Futaba radio control leads use the pressure switches wired to the transmitter to go under the cushion's to switch the transmitter on and off and wire the mouse to the reciever via the Futaba leads .

You could steer the cursor via the transmitter as you would only have to steer it within the 2 axis to hit the slide change button where it should remain fixed and be triggered by the pressure switch.

This is just a hypothesis but it just might work anyway it's worth experimenting

Wishing You A Happy New Year John M

Hello John,

That sounds interesting. If I have understood you , I did not think about a mouse having pressure switches in. I will let taankk know, and keep you in touch. Taankk is a little slow to reply sometimes but I will send a note to tell here what you said.

Thank you..............

Hi

The pressure switches are the ears of the mouse the scrolling is a potentiometer and the scroll wheel the only problem is keeping the cursor over the hotspot to effect a slide change

Hope this is of help in a very difficult subject which means wrecking equipment to acheive a result.

Best Regards John M

Hello John,

I thank you for your reply post. That is interesting about the mouse made up like that. I know that the pressure switches taankk wants, and I may want some as well, are only about £1,00 each. But they come from the US so postage is going to push that us substantially. You can buy a basic mouse for not much much and she would only need 5 mice. So it would work out cheaper and easier to source!

I spent a couple of weeks searching and was successful in finding what she wanted. I was looking so hard it was very intense. And I assumed she already knew about writing a short program for Excel to run this system but, she said she was not familiar with it or something like that........It is a few weeks ago and a cannot recall what she said exactly. After that I 'chilled out' on some easy searches. She said she was going to ask a question in the programming section of this site as the Engineers part had kind of dried up.

Anyway, she can get the sensors she wants from 5 mice. I have given two or three possible ways she might get the computer to acknowledge the signal but maybe she just did not want to try anything out at that time?

I will get into it again in a week or so, but at the moment I just want to get into other stuff but, I do want to get back to it and now I know a mouse will give me two touch sensors it will make things a lot easier, thank you.

This project and another on Polar Mohr guillotines I spent a serious amount of my time on and, well, got not much back. I lost sleep over it and was working 16 hours a day so, now I am not getting THAT involved unless I can see it going somewhere with a conclusion and maybe a 'product' at the end. Do you see what I mean?

I would like to keep in touch with you OK? But I want to be less intense in the help I give. I hope you can understand that, and that I am not getting at you in anyway? Keep in touch as little or as much as you want. It is the searching which I found on those two threads to be a little wearing.

Take care and have a great new year.............

I am into some really serious G code for CNC at the moment and i have no idea of code using excel I will be exchanging information that will be mutually useful too us G code users in CNC forums
