  • Re: Faded lettering on Beomaster 3000 faceplate

    [quote user="matador43"] Please could you elaborate on your process, please? [/quote] Print mirror image onto paper, maybe high quality gloss paper or photo paper using a laser printer. The toner on the page can be transfered via heat. This is often exploited for metal etching/pcb printing. It may not be super robust, but many of the original transfers are pretty delicate, so... I have transferred print to a bit of aluminium tape just using a standard household iron. I might start doing

    I've had an idea, but not yet tested, that scanning and then printing a reversed (enhanced/remastered) image on a laser printer might provide a way to transfer a new decal onto the surface. I've successfully transferred toner onto aluminum tape, so it should sort of work, I just don't know it will be good enough.

    I had a delivery today Yes, I know they are white - nothing a bit of dye can't fix. The keypad is still really a prototype as all my home prints break the retaining tabs almost instantly when test fitting, they just don't have the flexure required out of my Ender3. This seems much more promising. The tuner board is basically be done, as I have tested fit extensively, albeit printed as two parts and glued together - not a long term proposition, but fine for prototyping. So this should be 100

    Is there a short in your output transistors?

    [quote user="fkatze"] [/quote]So this has been a while in the works...a few delays here and there...being stuck in another country, etc etc. But I finally put an order in for a new board and keypad for my beocord 8000 to be printed on a commercial printer using better material than I can do. Found a place with a more reasonable price, and if the test order works out, I hope I'll be able to offer a plastics kit for the BM2000 for anyone interested. I should receive the test parts in

    [quote user="Johan"]The spraypaint did not last long.[/quote] Once upon a time I changed some 80's tan interior pieces in a car to black using can of spray paint, and prepping with ESP (https://www.tradepaintdirect.co.uk/products/owatrol-esp-easy-surface-preparation - I think this is the same stuff, different tin, but whatever). Really got great adhesion, and even on high wear parts like door handles, never wore off.

    Cheap general purpose (black) Nichicons will more than likely suit.

    I'm glad you've got it up and running again. Hopefully it holds up and doesn't cause you any more troubles.

  • Re: Beomaster 5500 blown power transistors

    I'll assume you have a mulitimeter with continuity testing... Put probes on each of the legs of your output transistors - if you get shorts (beeps) between legs, then you'll need to pull it out and replace most likely. From memory the short is usually from the middle to an outer leg, but easy enough to test all combinations. Once bad transistors are removed, I think you should be able to power it on safely - at least I could on my BM2000. Flash of light sounds like a fuse blowing...? I'm
