sandisk made a wifi booster 64gb + sd share drive rechargeable fits in ya hand not bad lol ……this it better powerbank and shit lol
Fine Video Julian,thank you. I purchased 2 RAV File Hubs. This Hub works very well with those Memory Storage Devices. I also hooked my 4T hard drive with no problems due to the fact that the Hub supplies the drive with power as well. Both Android and Apple products can connect to it via an Application(free) and its WiFi feature. Try it guys,you will like it!!. From Amazon($42.00+Tax).
You say from power bank, crap power. No actually, i hear so.
Why not just drive it from the boost buck converter? (sorry if this question is stupid I'm a beginner)
The rav power file hub does look very useful, were it not for the fact that I have other devices serving the same purpose. Mainly my Hootoo wifi booster with usb file server and integrated power bank. Actually I ended up with two, one without the power bank, (The NANO) and a more up to date model with a Power bank built in. I picked up the latter because I use them in our RV, and I wanted to have access to our files etc. while mobile. Both work great, so I would think the one you have should serve the exact same purpose, however it is MUCH smaller then the large HooToo version. WE have found that in the particular RV park where we now sit, both work as a relay for the internet service, but strangely even though they sit about 20 inches apart, when one goes down, the other seems to stay connected longer. The wifi here is horrid to say the least, and our laptops seem to need the boost of these little gems to even stay connected long enough to see your videos. As it has ended up of late, my wife stays connected to my newest one (I have named killer) while I use the old one (named hunters) and we both do fine, but confusingly when we both connect to the same device, it seems to slow both of us down to be practically unusable. Wifi is indeed a step into magic and witchcraft it seems even for those of us with some understanding of the function of such devices.
How much did that bord cost u bro
I have those Drivers, but i cant seem to get the thing to dim the leds using a PWM motor controller on the EN pin. can u do a video explaining how this is done?
Do i need a led driver ?
I am building a high power flashlight 🙂
World light would be internet connection I'm guessing.
Hi Julian,
I've been watching your videos and I've been really enjoying them.
I was just wondering which you thought were the best value for money powerbank and charger doctor.
I have watched most of your videos but I don't know the answer to this question with out watching them all again.
Thank you
Did you ever test the focal lens on the 100w led?
I'll be waiting for the full review. I need a WiFi extender. Also keep the videos coming. They are informative.
Hey Julian, you surely have some experience with ordering stuff from China… Did you find any seller from ShenZen or Hongkong that offers this kind of stuff with some sensible kind of shipping? I'd rather pay a normal shipping rate than waiting 4 weeks and then missing half of my orders.
you should use bigger wires for the LED. 3A is alot of current. the smal wires you are using are bnot quit made to handle thos types of current. awesome video btw.
I have a Vertibam version of the ravpower device! Its handy when your out transferring photos/videos to a memory stick! also putting films on to watch on your tablet!
Pal, invest a FLIR Thermal Imager since you are so into higher power and high temperature hobby.
