dubka Posted September 16, 2009 Report Posted September 16, 2009 Is it just my build or is the lcd set quite far back from the front panel, leaving a noticeable "hole"?And the cs switches are making direct contact with the pads on the lcd. Am I doing something wrong?Also, what sort of screws are you using to fix the lcd to cs pcb?I've found everything about the MB-6582 quite well documented, except fitting the lcd.Cheers,Martin Quote

I used a strip of tape to separate them. M2.5 screws fit perfectly, but M2 works too. Quote
Wilba Posted September 16, 2009 Report Posted September 16, 2009 Is it just my build or is the lcd set quite far back from the front panel, leaving a noticeable "hole"?No, that's normal. I put a piece of 3mm slightly tinted acrylic in between the panel and LCD. You can cut it roughly because you don't see the edges.And the cs switches are making direct contact with the pads on the lcd. Am I doing something wrong?I thought I wrote to solder them from the top and cut the leads close to the PCB. Use sticky tape or card to insulate.Also, what sort of screws are you using to fix the lcd to cs pcb?2mm or 2.5mm screws.I've found everything about the MB-6582 quite well documented, except fitting the lcd.I nominate you to update the documentation to share what you've learned. :) Quote
dubka Posted September 16, 2009 Author Report Posted September 16, 2009 I'm allowed to do that?! One thing I would definitely update is the "optional" on the transistors.Anyway, do you mean to solder the lcd leads on the panel side? Or to solder the switches on the base side? Sorry for the possibly obvious questions but this stuff is too expensive for me to just guess. Quote
Wilba Posted September 16, 2009 Report Posted September 16, 2009 Solder the switch leads (and any others like diodes) that overlap the LCD from the top side, this lets you cut the lead on the bottom side as close to the PCB as possible.Solder wires to the LCD from the bottom side, flat against the pads, not through the hole.

dubka Posted September 17, 2009 Author Report Posted September 17, 2009 Solder wires to the LCD from the bottom side, flat against the pads, not through the hole.How do you hold them in place to solder?Don't really understand the reasoning here - I wouldn't have thought clearance on the top side of the lcd was an issue...?

Wilba Posted September 17, 2009 Report Posted September 17, 2009 I said the bottom side... aka the side that isn't going to make contact with the CS PCB.Solder them using a reheating technique... strip and tin the wire, add a blob of solder to the pad, then put wire onto blob and reheat with iron.

Smithy Posted September 17, 2009 Report Posted September 17, 2009 Solder them using a reheating technique... strip and tin the wire, add a blob of solder to the pad, then put wire onto blob and reheat with iron.D'oh!I never thought of soldering wires that way!And there was me melting the insulation all along thinking it was the only way!You learn something new everyday i spose! :) Quote
dubka Posted September 18, 2009 Author Report Posted September 18, 2009 You see - it was exactly that type of "idiot-proof" explanation I was looking for.My forgetting that the lcd was mounted on the bottom of the pcb was the low point of this thread for me :-PCheers Wilba Quote
Wilba Posted September 19, 2009 Report Posted September 19, 2009 LOL... I didn't think to be explicit about "mount on the bottom of the PCB" because the switches clearly overlap and it can't fit on top. Quote
fussylizard Posted September 19, 2009 Report Posted September 19, 2009 Check out these pictures from my build: http://picasaweb.google.com/fussylizard/MB6582?authkey=Gv1sRgCM7npqbPgvbfYA&feat=directlink#I have a few dedicated to how I mounted the LCD. I also have one that shows the wires soldered to the bottom of the LCD (though I should probably show a more detailed version of this). I should probably get around to posting a link to these pictures somewhere... :-)I have lots of notes and such I still need to post from my build, such as an "additional" parts list for all the extra nuts, bolts, female DIL headers, etc. that I need to post since it took me (IIRC) 2 orders from SmashTV, 3 or 4 orders from McMaster-Carr, and 2 or 3 orders from Mouser to get everything. I could have probably figured it all out had I thought about it more, but there were some things that I just wasn't sure about or forgot about. It would probably be helpful to others to see all this extra stuff to augment Wilba's already excellent instructions.Hopefully I'll get to that after I finish up running the 40x2 LCD bulk order...

lief138 Posted September 19, 2009 Report Posted September 19, 2009 I just got done looking at your pics and all I can say is pic 18 is brilliant. Thats one way to keep it clean! Quote
