Nice work Dez. Have a good weekend mate.

 

 

 

Thanks guys

 

Ben, I will put your one in the same box as the tube and other gear mate :)

Fantastic stuff! It's always good when things work straight up (but that doesn't always happen)......This should encourage you onwards and upwards to bigger and better things - not that this project is "smaller and worse" but, you know what I mean...:rolleyes

 

Cheers Mate

It will for sure spur me on, I want to now make the deflection board for the same monitor type, it's area is 3 or 4 times the area of this one :) But the parts are further apart if that counts for anything

Hi Guys

 

I am also making a few parts for these. If you are transferring from 1 board to another you may not need these. If making a HV board from scratch, these parts will be needed

 

I would like to get quantities of these fairly soon, to decide how to get these made

 

Already designed and tested (QTYS needed)

  • Mystery Can MC1 $30.00
  • CRT Connector and neck board $17.00 (Not including harness at this stage)
    EDIT: Tracks will be on other side next batch - oops :D

 

Intended to make (Parts in hand)

  • Driver Transformer T1

Update:

 

I made up a winding rig today, so I can wind the T1 tight (T1 is that strange looking white thing in the middle), a prev attempt was wound too loose and the ferrite didn't fit -FAIL

 

Now, after using the winding rig, the E shaped Ferrite core thing fitted over the bobbin

 

Success!

 

So the first ever repro T1 has been made :)

 

Original T1's readings were 9 Ohms and 0.18 Ohms

The reading was 8 Ohms this time, and 0.2 Ohms (I worked out the current will rise by 1.2% through Q2 as there is a 39 ohm resistor in series) The current is still 1/4 of the rating of the MPSU07, so don't worry

 

Anyway I had about 4 games and killed the death star etc each time, and no ill effects at all

 

THIS IS a rough prototype

http://www.dsbelec.iinet.net.au/Proto_T1-sm.jpg

 

The core is taped together as glue is permanent.

I am getting the proper base made up - it will be glued once I am finished with the base

 

 

So onto the Neck board:

The final design has been sent off / ordered

 

1 x PCB contains 1 x Neck PCB, 1 x MC1 and 1 x T1

T1 needs 2 pieces, piece 1 flips over and is soldered back to back with piece 2, then the transformer is fitted into that slot and the wire is soldered to the small solder pads

I just need to do a bit of soldering . . but that's OK :)

Great stuff Dez - what FBT are you using for these?

 

I got them from twisted quarter, but it's the same one everyone is selling at the moment

 

All parts are here

 

The FBT is here

http://www.twistedquarter.com/index.php?main_page=product_info&cPath=206_216&products_id=1155

 

If people get a new FBT, I STRONGLY suggest they unwind 1 x turn off the white coil, to reduce the heater voltage from 10V down to 7V

 

I have added heater voltage test points on the neck board to check it

Heres a clearer pic of the Neck PCB showing heater test points

Here's a better pic of the Neck PCB, showing where you test the CRT Heater voltage

The PCBs are on their way, shipped a few days ago :)

 

Some Little transformers (T1) wound and glued, ready for the base to be attached and soldered on

First batch of T1's waiting on a base

http://www.dsbelec.iinet.net.au/First_T1s-sm.jpg

 

The HV Cable arrived today for the focus wire. I ordered enough to make 6 or 7 boards. Had to make sure it was correct. It is correct, perfect for the purpose, white in colour as per the original

 

The neck connectors supplied will have this focus wire attached already, to ensure no one zaps themselves

Boards are here

 

Once I have a few more parts made I will start a For Sale thread

I started winding the MC1 parts also, waiting on more still . . .

The other PCBs (Neck, MC1, T1) will follow soon

All parts have now arrived to finish this project, and I will try to get the last parts finished / assembled this weekend. Payment to be asked for next week sometime

 

If interested parties would like to email me for now (derricksb@iinet.net.au) Same email as Paypal, when time comes

 

  • Name
  • Address
  • Phone
  • User name
  • Qtys needed of PCB, MC1, Neck Conn and T1's

 

I need to finalise the list and start working things out

 

Thank you

Re bumping this thread for those who have not already let me know . .

 

I need names and addresses and final numbers please guys :)

I don't want to make 50 items if only 30 are needed. Does anyone want the smaller parts, like MC1, T1 and the CRT connector?

 

Cheers guys

Important if using the WG6100 Focus block on this PCB

 

I have worked all day to solve a problem related to the HV cutout, only if using the WG6100 Focus block using this MOD HERE

 

It's been reported to me the HV board does not cut out when performing the Test here

 

 

My board (With the 6100 Focus Blk) did the same

 

I won't list the 25 steps I took to solve this, I will simply tell you all the solution

 

If using a WG6100 Focus block, replace R19 with a 100K, 0.5W resistor

 

And I had to turn the LED around 180 degrees, Hmmm?? I just did it and it worked

 

Happy vectoring :)
