    Hmm, must be a limit they applied later? I've got 12GB of free space I've gathered just through promotions, and never exceeded any bandwidth limits.

    Yeah I understand. My Dropbox folder is a mess with images, but I can't clean it up or I'll break all my image links too :p

    Looks like I have 2 of the v5's .. also a couple 3.8mm 50mW 520nm diodes apparently. Interesting what you find when you look ;)

    I might have a few flexdrives somewhere .. I'll have a look when I'm home :)

    How old are we?

    Can I updated my vote? :D

    Couple new pics

    Hit up member "hakzaw1" if you're looking for a projector (and FB3/QuickShow), he's more up to date with what's on the market than myself. I built this one a few years back and it cost me around $2500 all up, but you can do it much, much cheaper these days (or just buy a complete unit). It...

    Not much, but yes.

    Couple new pics

    Messing with my projector and new camera the other night, managed to get a couple good pics. Need to grab everything out and do it again sometime :)

    Have an extra $50K to see if there are exotic laser diodes in this new projector?

    If the image remains in focus even on curved surfaces, then the light source has to be red, green and blue diodes, and it has to be scanned like existing laser picoprojectors. If it uses similar tech to the prior projectors (blue LED's and a phosphor wheel), the image wouldn't stay in focus on...

    Epic Huge RGB Digital Clock

    Yeah I haven't had too much use on the scooter unfortunately. Cos I'm fairly heavy and it's so hot where I live all the time, I have to be very careful to not overheat the motor. In time I'll probably move further South to the cooler climate, and hopefully have lost a bit of weight with my job...

    Epic Huge RGB Digital Clock

    I came back to this thread to update it with how the clock was going .. but now I'm realizing I never even posted the actual finished project. I swear I remember posting about it somewhere .. In short, I ended up ditching the custom little controller boards as they were a pain to wire inside...

    Which diodes are mutimode?

    Generally lower power diodes are single mode, higher powers are multi mode, but there can be exceptions to the rule. Low power 445nm diodes are singlemode, as are low power 635nm diodes. Only sure way to know is either check it's output, or the datasheet.

    Cavitation Heater - Overunity

    No one is disagreeing that the device can indeed heat the water, the energy has to go somewhere, and eventually through friction it will be turned into heat (and indeed, how the device works), but the fact that it's driven by an electric motor, which are still not really even close to being 100%...

    Cavitation Heater - Overunity

    Except, in this device, it's not harvesting energy from anywhere, so overunity or free energy machine, doesn't matter, it's still less efficient than electric water heating. Towards the end of the first video the "actual scientist" even states they didn't record enough meaningful data to prove...

    Cavitation Heater - Overunity

    Yes, I'm completely aware of how the device is "supposed" to function, I don't start telling people they're wrong unless I've done my research and I'm 100% sure they are. In this case, I'm 110% sure. "This is an engineered device" .. isn't everything? As far as I'm aware there hasn't been any...

    Cavitation Heater - Overunity

    It CAN NOT be more efficient than electric heating. This is why people are taking the p!ss out of you. You keep claiming it's MORE EFFICIENT than electric heating which is ALREADY 100% efficient. To be MORE efficient than electric heating (in this sense, ie, direct water contact), it's...

    Cavitation Heater - Overunity

    OK, you have a piece of wire submerged under water, and you pass 1 volt at 1 amp through it. Ohms law will tell you that you're passing 1W of energy through this piece of wire. What does it do? Gets hot. ALL of the energy you're putting into this wire (or heating element, if you'd prefer) is...

    Looking for a boost IC

    Cheers everyone, I'll have a look. I've been looking at the tps61092, which granted is QFN but seems like a pretty neat chip, but seeing some better looking ones here :D

    Looking for a boost IC

    I'm working on a project at the moment where I need to be able to generate 5V from a single LiIon cell. But having a bit of a hard time finding an IC suitable. Basically what I need is: 5V out from single cell LiIon 500mA current (preferably without heatsinking) Active low shutdown pin (GND =...
