Anything special about this seller ?

Hi,

I got a QL with a missing speaker. Anybody can point me to a electrically compatible one ? I don’t care if the size is different, as long as it produce sound! Beside impedance, anything else I need to know ?

Thank you

François

Hi, I was finally able to fix my network board. I received the correct BAT-43 diode, installed it, but as many of you guessed, it did not solve the problem. Then I realized the network signal would go high whenever I would plug my interface card. As a matter of fact, peek(hex(18020)) would give 57 a...

Hi Francois, Did you take the message by Dave into account with a bug in the circuit diagram you ... You should check your circuit with the file supplied by Peter, supplied here for reference. qlnet.pdf My understanding was that the error was in the Gerber file, not in the schematics. I used Dave’s...

It does. When I apply 3.3V to the QLnet pin, the value becomes 57. Let's wait for the BAT43. SInce your test proved that your Q68 FPGA has not been damaged, I would not expect much from replacing the diodes. Did you check their polarity, by the way? Peter, I used Dave's schematic as found here http...

BIG problem

Figured it might be but thanks for the offer!

Francois, I might have a last spare PSU still available. It's handmade and provides more power (2.5 Ampere or more). I've sold 4 similar PSUs. A person asked for it years ago. I may ask that person: he might no longer be interested. Sure I would be interested, however I am located in Canada, so it ...

Common GND is in fact either side of the AC transformer output, which one doesn't matter (BTW I managed to scavenge several 12V transformers from some cheap Chinese Christmas lights my wife wanted to throw away - They seem to be a good source for this and are even outdoor rated ;) ). The Tetroid (a...

Even if it worked for some time, I wouldn't load that good 'ol PSU with nearly twice its rated current. The switching regulators do in fact slightly reduce current input, but not that much. Even if you made it work, you'd still be faced with the nonstandard power connector. Stitching together a 9V-...

... if both QLs are equipped with Teroid switching regulator ? Would the better efficiency of the switching regulator be enough to reduce power consumption by half ? These PSU are difficult to come by so using a single one for two QLs would be nice. What if one of these QLs has a GoldCard ? (My unde...
