  1. Fitted the LCD replacement to a broken Lynx I have today, now works great and display is wonderful, so much nicer than the original one. Have fitted the VGA connector but not had chance to play on a big screen yet.

     

    The circuit board seem well made, lot nicer than those early pics McWill posted. Very minor quibble but would have been nice to have some kind of brightness adjustment, if playing in a dark room it could go a bit lower. Also might see if I can find a differnt VGA connector thats black as the white one stands out a little.

     

    Probably order another one now :-)

     

    Hey Radfoo. Did you really fit the LCD in a Lynx I (one). Do you have the right Pinout for this? McWill mentioned the LCD wouldn't work in a Lynx 1. I would love mor information about this ;)

  2. Well, he tried to repair them, but he failed. In some of them he replaced the voltage regulator, some of them are missing the CPU/GPU and so on. There were 3 cases in the lot. I hope to get at least 3 boards to run again. Unfortunately i don't have spare time till march or so...

  3. I'm actually quite intrigued about those components, what they are and why theyre not essential with this mod..

    It's essentially a royer osciallator or CCFL inverter which converts low DC as provided by batteries to high AC, as needed for the old lynx backlight. The new LCD does use LEDs, which only need low DC, so the inverter is no longer useful. The overall current consumption goes down, if these unnecessary parts are removed, so battery runtime goes up :)

     

    Clearly we need to harness McWill's talents - next challenge, a new LCD screen for the Lynx 1 :grin:

    I guess he's to busy to answer right now, but i think this will indeed be his next project.

    I used a ASSMANN A-HDS 15 LL/Z VGA Connector which has black plastic.

     

    I would love to have this upgrade, but soldering is not necessarily my strong suit. How much is the mod kit? How to get one?

    You can get one right from McWill by writing an Email to: order-lynx-lcd[at]online[dot]de

    He charges 95€ plus shipping depending on where you live. I think he used to mod Lynxes himself, but i don't know if he has any time for it right now.

  4. Thorax, are you well versed in this or experimenting?

    I'd look up the Nomad battery mod for some reference tips, though you'd be adding a new internal port. Maybe your just way better off with rechargeable batteries in this case though sir.

     

    I think i do know what I'm doing. I just experimented with the step-up-converter to check if there's any interference with the Lynx. Turns out it works fine. I added two 18650 Li-Ion cells in parallel, undervoltage protection and a USB-charger. I'm not sure about the runtime yet, but i played for about 3 hours and had no problems. If the step-up was 100% efficient, the Lynx would run for about 8.6 hours. If the efficiency of the step-up is at about 75% I'd still have about 6.5 hours runtime :)
