I'm so happy that I got this scope as my very first one, delivery was pretty fast and the box it came in is sufficient to prevent any damage. The probes that I got with this scope are 80MHz rated which is great. My scope came upgraded to 200MHz from the factory so no need to do that yourself, there's new firmware that you can download for this scope on the Hantek website dated 02-25-2021 ( Link: http://hantek.com/uploadpic/hantek/files/20210225/dso5kp_func_dso5072p20210225.rar ) and you can safely install the new firmware without having to worry about losing the upgrade to 200MHz that will stay exactly the same, you can trust me about this because I just did it myself and I didn't know for sure if it would go alright and the seller couldn't tell me either but I assure you the firmware update can be done safely. I also opened the scope just to have a look inside and to my surprise I found that it has a slot for a micro SD, I had one 16GB to spare so I put it in the micro SD slot and now I can save stuff to the internal memory card instead of using a USB-stick. This isn't mentioned anywhere so I thought you might want to know this. This scope will be more than enough for the things that I'm using it for so I'll be using this scope for many years to come, if you are not sure which scope you should buy if you haven't had one before I highly recommend you to buy this scope because it is hard to find a similar one in this class for the price. I've included a couple of pictures to show that the box came in undamaged and that I've installed the new firmware and it's still a 200MHz scope. Thanks Banggood for the great service, I'm really happy with this scope.

So I got this drone delivered today and I think it's awesome, to compare it with the DJI Ryze Tello drone that I also own I can already tell you that this drone is at least as much fun if it's not more even. If you already have some experience flying drones, this thing flies just as a normal drone with the motors on the 4 outside corners, the difference is negligible. In fact this drone is easier to control because it has a dedicated real controller that works really well, just on the first flight I recommend you to go in an area where you have enough room around you to be able to hover and use the trim buttons so it will hold itself in the same place if there's no wind of course but it does it really well. I haven't figured out yet how to switch between the two camera feeds but it worked for me right out of the box. I didn't have to do any weird button combinations or anything like that, just put the batteries in the drone and the controller, connect the drone to my phone with the app that also works quite well and when it all connected I could start to fly within 10 minutes how cool is that? I'm absolutely going to have a lot of fun with this little drone and I'm so happy that this one came to me right at the time that my older drone the Ryze Tello has dead batteries so this one couldn't come at a better moment in time and I want to thank Banggood for their great service and for sending me this product free of charge to test it and give my honest impression and it really is. I tell you this because I want you to know how I got this to be transparent and my opinion is not biased it's just a really well put together product that just works straight out of the box. I highly recommend this drone to anyone who wants to have some fun with it and especially beginners since it's so easy to fly and it doesn't cost you a fortune in the worst case scenario should you destroy it by accident. I hope this review is helpful to you.

pendersricardo UPDATE: Because of the app not working on my phone and not getting any answers from Vstarcam support I decided to try and hack this camera, which is too easy and may be a security risk even. I hacked my Arduino Nano so that I can use the USB to TTL chip on the backside of the Nano separately using the RX and TX pins and with that connected to my home made level shifter board (because the camera\'s UART pinout is 3.3 volt and the Nano is 5 volt logic) I can now read out all the information I need to reprogram the camera so I can do whatever I want with it without using their app or cloud service. If you\'re interested and want to know how to hack this camera you can go to my GitHub page at: https://github.com/soharddbwarez for more info.

pendersricardo So now after a year using these resistors I can tell you that these are very strong resistors capable of double the amount of power that\'s on the specs, by accident I\'ve pushed these resistors to 220 watt, I did mount them on an old CPU cooler of course and I have active cooling using a fan, they do get really hot and I don\'t know how long the resistor can take that amount of abuse but I\'ve let my test run for about half an hour and they are still within spec and working as new so no problem to overdrive these for a short while.

pendersricardo TheESP8266 chip is embedded together with the Arduino UNO and you can use them both at the same time using the mini dip switch, you can also choose to use them separately via the dip switch setting and the 32Mb flash is shared between the two microcontrollers.

pendersricardo ThisLCD display only works with I2C, that's because of the extra PCB board on the backside which makes it easy to connect to an Arduino Nano for example as I do it personally, if you have the Arduino IDE installed on your computer open it and go to Tools, Manage Libraries or use the hotkey combo CTRL SHIFT L to open up the Library Manager and then search for the LiquidCrystal_PCF8574_Test library, install that library and with that library you have a test sketch in the Examples that you can use to get familiar with the code to get this display working.

pendersricardo Thename of the Bluetooth device is UD18-SPP and the Android app you can download via the Google Play Store, search for E-test, it's a black and red icon. After opening the app you have to select the device by clicking on the Bluetooth icon located at the top, only then it will show you the USB device and will let you control it via Bluetooth. I can assure you that the app works on android phones and my phone is a Galaxy S5 which is already 6 years old.

Q: Please add pic of controller?

pendersricardo As I'm writing this answer to your question I'm going to upload my pictures and I made a couple especially for you to show you the controller, it takes two AAA batteries FYI. So just lookup my review above and there you can see the controller with your own eyes, I can assure you that it is a proper and good working controller even though it's quite minimalistic it's super easy to fly this drone with the controller, you can also choose to control the drone with your phone only just as the Ryze Tello drone but I prefer the real controller because of the feedback I'm getting from the sticks and buttons which just isn't comparable to a flat screen with virtual buttons, it's just not the same.

pendersricardo Please contact the Banggood customer service and they will for sure help you with your issue, all the issues that I've had were all handled absolutely without any hesitation from Banggood's side I have to give them that one, ordering from China really isn't as bad as people may let you believe and Banggood is to my opinion a very trustworthy website because of the great customer service. Just one tip, the person who's helping you isn't responsible for the issue so please keep that in mind and try not to get angry, they don't deserve that and when you are friendly, well my experience is that they will do anything they can to fix the issue to your liking.

Q: 32 megabytes memory is only for ESP8266 or for both ?

Kérdezte Antoine tovább 2019-12-24 09:12:31

pendersricardo it'sfor both, the memory is shared between the Arduino chip and the ESP8266.
