    Just picked up this unicorn power mac g4 for cheap. It's got 1gb of total ram, at two different speeds and three different capacities because why not. It also has some sort of aftermarket "owc" CPU upgrade making this have a 1 GHz G4 processor instead of the normal 400MHz-ish it should have. It's quite unique and a ton of fun since the previous owner had separate drives with Mac OS 9.2.2 and 10.3. It's also a bit quirky; the boot chime only functions when Mac os 9.2.2 is selected as the boot drive. When 10.3 is selected the monitor looses signal until it starts logging in about 50 seconds later which then the desktop appears. I can't figure that one out along with why the CD drive opens by itself during the boot process of both OS 9.2.2 and 10.3???
     
    It also looks to have an 8 pin mini DIN port instead of a phone jack?

    DarkEnergy reacted to mariushm in Charging solution for old calculator, can it work?   
    I would not use connectors, if the battery comes with such connector I would cut it off and solder the wires directly to the charging board. 
     
    It seems there's enough space where those 3 pins are that you could even install a usb type A connector there, but a micro USB or a usb type C connector would make more sense, as you can then use phone chargers or just plain usb type a - type c / microUSB cables to charge the calculator. 
     
    If I had that calculator, I would look into heating up those 3 thick pins until they can be pulled out of the plastic and then maybe enlarge the hole (join the 3 pin holes together) to make it possible to have a USB connector in that area, where the 3 thick pins currently are. You could use hot glue or other techniques to lock the connector into place there. 
     
    For example   microUSB connector on a tiny PCB which has mounting holes : https://www.ebay.com/itm/322763194358
    You could literally make a channel just thin and wide enough to slide the pcb from the outside and then drill two holes in the plastic and use a couple screws to lock the pcb to the inside plastic, then maybe even use some hot glue to lock it in place 
     
    Here's examples of usb type-c with tiny circuit boards to solder the wires to : https://www.ebay.com/itm/275173990222
    This would be harder to lock in place in that compartment, I'm thinking lots of hot glue as the only possibility.
     
    You could also use a barrel jack connector, but usb would make more sense because it kind of limits you to 5v. Cheap lithium charger chips can only handle up to around 5.5v-6v, so by using a USB connector you're sort of ensuring you're not gonna go over 5v.  With a barrel jack connector, you or someone could accidentally plug a 7.5v or 9v or 12v adapter into it, and you'd blow the charger chip. 
    If this was a commercial project and barrel jack connector is a must, then I would have to add an extra linear regulator or a step-down dc-dc converter to convert whatever comes in, down to ~5v, to protect the charger chip, or I'd have to use a more expensive charger chip which has wide input voltage range.
     
     
    Now last but not least... something I didn't mention previously.
    The charger board I linked to above is just plain charger, it charges the battery by monitoring how much current goes into it and how the voltage gradually goes up to around 4.25v as the battery is charged. 
    These kinds of basic chargers can get.. let's say "confused"... if you also take out power from the battery while the battery is charging, basically they won't damage the battery or anything really bad but it's not good for the battery over long term. So in general, with such basic chargers, it's not recommended to also use the device while charging the battery.
     
    There are smarter, slightly more expensive charging chips which can act also act as a switch between battery and dc input. When input is detected, the chip disconnects the battery from the output and starts charging it, and at the same time is has a built in voltage regulator to send power to the output directly.  When input is disconnected, the chip connects the battery to the output. 
     
    For example, here's such a smarter chip with board : https://www.ebay.com/itm/142668705028
    but note that you don't need that super big capacitor... it's recommended to have a capacitor soldered to the circuit board in the footprint, but it can be a small 10uF 10v+ rated electrolytic which can be laid flat on the board and use 5mm or so of height.
     
    So in the picture  below  PWR and GND are your input power  (going to Vbus and GND in usb connector) ,  BATT and GND goes to the lithium battery,  LOAD and GND goes to the step-up / boost dc-dc converter to produce that 7.2v DC the calculator needs.

    Looks live I've fixed the problem with permissions. TBH I don't know what the solution was because I forgot to check if UHC1 was running or not between each fix. I think the solution involved changing owner of "/usr/bin/crontab" and "/etc/suspendfix.sh" to my username. I also set chmod for the "/etc/suspendfix.sh" file to 775. So far so good, I've rebooted and UHC1 is now gone.

    DarkEnergy reacted to Tigerleon in Good wired headphones for music under $200 USD   
    Do you want quality or quantity in the bass? You won't get very much subbass on open backs, that is just how it works. There are many headphones that has better bass than many closed backs. It is just a matter of how they are tuned, the pads and the space between the ears and the driver etc. 
     
    The 770 pro 80ohm are fine just not up to par with the 250ohms for what I've heard. The 250ohm will sound better when amped. The 80ohm isn't just the only calculation of needing or not needing an amp since the sensitivity is also a major part in that. All in that series of beyers are pretty hard to drive even if they are 80ohm. The thing most people think is, I will probably get enough volume. But in reality volume isn't the only thing. It is about how well the whole frequency range can sound throughout and not sounding sloppy or losing detail. If you've got one of the newest onboard audio then you might get away with it fine but an amp will definitely improve the sound coming out and a cleaner seperate DAC.
     
    If you do not want to get an amp just skip this part
     
    From Hifiman's store you can find a pair of HE400i 2020 edition which states that they are opened but in reality just shown off or just tested. I haven't listened to these but based off of reviews they are very good planar magnetics for their price.
     
    They are really fast in terms of their driver tech and can play bass heavy stuff without distorting the rest in the FR better compared to dynamic headphones.
     
    They are also more open than the X2HR's and have better imaging. These are quite balanced but are more bass light and pretty rolled off in the subbas region than others you've got. You can always EQ but I can't tell how good it'll turn out but I think they respond well to EQ.
