Wireless IP camera review - T7838WIP

  Hello everyone, how is it going? Today I will be reviewing a nice wireless IP camera: the T7838WIP 720p WiFi capable camera, made by VstarCam and brand-labeled by MANY others. Note that I have also recorded the above video with the actual T7838WIP camera.

Some specs:

- Up to 720p video (1280 x 720, HD)
- WiFi capable (works with Ethernet as well)
- Infrared LED's (night vision!)
- Supplied by 5v power adaptor
- Pan 355º and tilt 120º
- Captures and reproduces audio on camera
- Works paired with the Yoosee app (Android and iPhone)
- micro SD card for recording (up to 32GB)
- Supports ONVIF protocol (can be paired to compatible DVR's for recording and monitoring!)

Starting it up is as easy as three steps:

- Download the Yoosee APP on your phone (and open it)
- Power the camera UP on the same WiFi network as the cellphone
- Follow the app instructions!

   This camera has positively surprised my in many ways: the fist is the image quality, 720p over WiFi; there is also the capability of capturing and reproducing sound to and from the camera and the APP (you can listen and talk to whoever is close to the camera - I recorded the video this way!). Finally the capability of panning and tilting around -in real time- amazing. 

   As far as buying this camera yourself, I can only recommend it and give you two links where you can find it: GearBest (here) and BangGood (here). I hope you guys like the camera and this article about i; see you soon!.

Arduino-based datalogger - DIY data logging

   Update: this project is also on Hackaday.io: https://hackaday.io/project/21409-arduino-datalogger-with-microsd-card

   Hey everyone, how are you doing? Today's video is all about a project I have been thinkering around (and designing) for a long time: an Arduino-based data logging system. It basically reads data from Arduino micro's analog and digital inputs and saves it to a microSD card.

   The reason I created it is that I need a datalogger myself; I am always experimenting with analog and digital data from physical systems (rc cars, servo motors, etc etc) and I simply love to record said data for after-the-fact analysis and comparison.

   I have programmed it to read all four analog inputs of Arduino micro (A1..A4) and store the data in '.csv' format inside the microSD card; it allows me to easily post-process and copy/paste/move information. 

   The schematic diagram (made in Fritzing) for the datalogger is seen below, and the Arduino code can be downloaded in this link (or copyied from below as well - use it without worries).

FritzenMaker's Youtube Channel

Hey everyone, how is it going?

   I just would like to give you heads up that I now own an Youtube channel. Is is also called FritzenMaker (link here) and will be the main content platform for FritzenMaker (besides this blog, of course!!).

Have fun here:  FritzenMaker Youtube Channel !!

My first ever Instructables - a PCB mockup out of cardboard

   This blog post is about my first-ever Instructable entry: a PCB mockup made out of cardboard. I will explane it better:

   I live in a third-world country (Brazil); as so, many of the materials have to be imported. I work with embedded systems development, so importing electronic components is basically a daily task for me. I basically buy most stuff from China and get free shipping, and it may take up to 90 days to a free-shipped material to get to my hards: this is because customs in Brazil are slow and tough at the consumer, always willing to tax us a bit more here and there.

   One of the biggest slow-downs of an electronic product development is the manufacturing (and iterations necessary) of the printed circuit board (PCB), because it is almost an "art" and most designers don't make it right the first time.

   So basically on a scenario where anything can take 90 days to make it to my hands from China, I cannot afford making big mistakes!; this is why I have come up with a cardboard-based mockup of my current PCB design, so that I can mechanically test it before sending it to the (PCB) board house.

   Of course (as it is simples plain paper and cardboard) you cannot connect it to and a power supply or the like; this technique is intended to mechanically-test component collision and positioning only!.

   You can find my full instructable on this link. Hope you like it and share the knowledge with your friends.

Professional Electronics Blog - FritzenLab

Hello everyone, how are you doing today? the end of the year is approaching fast, right?

   So I came here today to present you my newest venture: an embedded systems professional blog!. I just left my job at a tech company in Brazil to startup an electronics design house, and decided that in paralell I would run a blog.

   One of my passions is to learn electronics, and be able to teach people what I have learned; this is exactly what I plan to do in my new FritzelLab ( <3 ), be able to pass my knowledge to everyone that wants to learn; all of that in a free and open way. 

The blog will be written in Brazilian Portuguese (my mother language) because my target is the Brazilian market and its proeminent maker scene!. You can enter my blog in here: www.FritzenLab.com.br .  

Feel free to comment and suggest (even in English if you will!). 

See you all,
