/g/YamahaQY70AndQY100/album?id=244175 the gameboy frontlight sits between the LCD and the front panel, sandwiched. Re: side lighting: no removal or peeling needed, just there is not room enough (IMHO) on the LCD sides. Firthermore, the LCD assembly is hold together by a metal frame that should be prforated in some way to make light pass. There is some space on LCD top and bottom, instead, but the metal frame is in the way as well. Peeling the LCD assembly reflective back is mandatory only if you opt for back lighting via electroluminescent panels. Not personally tried on the QY, but have some experience with EL films: nice uniform light, easy to work with, just the transformer is a pain in the (choose any anatomical part of yours) for 1) its size, although small, the QY innards are rather cramped, and 2) depending on the transformer, there s'always some buzz in the audio part, which is not an option. ;) On 20/01/21 12:55, Douglas Woodrow wrote:

Re: QY100 display light
Hi all! Nice with the gameboy light - altho I cant visualise how it fits? Above the screen, on the screen? I had success with an IKEA USB gooseneck lamp. Yes you have to adjust for glare but ANY extra light is good in a dark (atmospheric) room. Here is how it looks.??You can see you get a round 'spotlight' effect but if you pull it away from screen no glare and some ambient lighting.? Fine 4 me. No DIY or glue or anything :D

Re: Low back-up battery display
¿ªÔÆÌåÓýPretty sure you can still save to the SmartMedia card with a dead internal battery (but must be done manually), but you¡¯ll really want to replace that internal battery since loss of external power will lose your work.. Once the internal battery is replaced you should be good for upto 10 years of storing 20 songs and 64 patterns in the device. ?Note: Yamaha has mentioned that leaving a smart media card in the device when stored can shorten internal battery life... so only out it in when you want to save/load from it. ? ?Also, avoid formatting smart media on a pc card reader as that has been known to corrupt them, use the device instead. ?(Good advice for any device storage media IMHO).The battery is a CR2032, and on the QY100... to replace...you remove the back by unscrewing the back screws and then opening like a book with the edge closest to the battery door as the spine (so to speak)...reason is because there is a cable there that attaches to the battery compartment. ? ?Once open you can probably reach in and unplug the battery compartment cable and separate the two halves. Next you¡¯ll see a copper shield held on by two screws... unscrew those and lift the copper shield and you will see the battery... To remove battery you SLIDE it toward the spring edge and it will pop-up... Take the battery out abd out the new one in the same way and then gently push it in while sliding it toward spring then hold it down and let the spring push it back under it¡¯s tabs. The lay the copper shield back (be careful to ensure it is tucked in at tge top where it is still attached. And then replug in battery cable and close it back up like a book and put the back screw in... and you¡¯re done. (Note: Unlike the QY100, the QY70 does not have a copper shield and the battery compartment is soldered so you cannot simply unplug the battery compartment, but the rest still applies and it still easy to replace the internal battery on the QY70. Regarding lighting screen: People have put LED side lighting inside the QY70/QY100 but it is a very tight fit.. others have installed EL Panels which really makes for the most uniform backlighting IMHO, but it is also the most complex. ?I think the nintendo front light is a good idea unless you feel really comfortable with your tech skills as the other internal solutions are much more intensive and technical.

"lesser" QYs (100 & 70) have a battery holder. Energizer or Duracell, please. Or a computer-grade BIOS power cell. CR2032 as well. I also have a QY700, and its internal 2032 is still going strong after more than 20 years(Silver oxide batttery), but I already have a holder for CMOS/BIOS batteries ready at hand for emergency, since in the 700 & 300 the battery is _soldered_!

fantastic, with ebay link 'and everything' :-) (been auto-logged-out andDid not try any other kits: did a lot of research last year, and I came out with that kit, bought one and last spring it became unavailable, now I saw there is a new version (looks identical, I'll receive mine next month). i did actually pass a 'host select' cable in a car-boot sale ... :lol:You lucky! You now would need a pair of adapters (PS/2-like Apple serial connector to D-sub, and D-sub to USB...). I am using a standard DIN MIDI cable, hooking the QY through an UM-880 (but a cheap midisport would do as well, tried it) and I conveniently run the QY100 data filer under Wine on my Linux (KXStudio) laptop. so does anything bad happen if it accidentally gets switched? no MIDI?No, nothing at all: I'm going by hart, will have a look at the schematics lately. That slider switch on the QY back routes to ground the PS2 connector in two different ways: when switched on MIDI the ground is sent to a non connected pin. That is, when on "MIDI", the switch actually does _nothing_. When switched in the other positions, nothing changes. to recap (3 second goldfish memory) : so this sits *in front*? of OGYap. It site behind the plastic screen, and in front of the LCD. IT fits perfectly as a slice of ham in a sandwich: bread 1 is the front plastic screen, bread 2 is the LCD inside. You have to use two strips of sticky (very sticky!) tape included qith the kit. I uploaded a bunch of photos on the groups site... how is your battery consumption? (i never use batteries, doesn't lastWell, the QYs are known to be real hogs: the display's LEDs actually add a few milliamperes to a system that drains out six AA cells in 4 hours. In other word, battery consumption is already a problem without the light. I saw that someone uses 2000-2500 mAh rechargeable cells. |

first and foremost, no LOCA glue, no irreversible operations, no risk taking with our precious QYs! Just two stripes of (rather powerful!) double sided sticky tape. My only advice is work in a clean, clean clean (did I say clean?) environment, lots of compredded air, gloves on. Not joking, see further. The light I used comes and goes on eBay as a mod for the Nintendo GameBoy. As you have seen, I hooked it straight to the +3V rail, it's a year now and I have no issues, except for a small scratch I made (my fault) while I dediced to "clean up better" the screen: a clear demonstration of the deep truths behind the "if ain't broken dont'fix it" rule. That's because I did not care so much about "clean area" work. The Host Select Switch was a sort of out of the blue idea while studying the QY100 schematics: I did not want to pierce the QY case in any way (see above). I am just not so satisfied because when the QY is hooked up to my rig I would rather turn the light off, and that would cut off MIDI, which is not an option. There is no other way using that switch, since that position (MIDI) closes up a "not connected" pin straight to GND. Other positions can be tried... noone uses kinda funny serial cables in 2021 (a bit of nostalgia here for my RS232 cables...). An alternative would be placing the miniature switch sold with the lighting kit in the battery compartment... will perhaps give a try and report. Here's the link, about 14 $... and I'm buying a new one to replace the scratehed one, it itches, indeed... pulled the trigger while writing this, thank you for the inspiration ;) On 05/01/21 00:42, Douglas Woodrow wrote:

Re: Qy100 blank screen
That¡¯s a good point about the battery leak possibility. ?It¡¯s worth mentioning if you mix baking soda (not baking powder) with vinegar it will actually help dissolve battery corrosion even more effectively than vinegar alone. ? Also if battery corrosion gets on the PCB you could use a good electronic contact cleaner spray to remove (at least some of) the surface corrosive battery chemicals without impacting the electronics...thus preventing more issues down the line. CRC Electronics Cleaner:? Another thought (since is seems to boot up) is to do a blind factory reset... though this will cause you to lose all patterns and songs (except for presets). -- ¡°The longest journey starts with the first step." ?- Lao Tzu |
