Arduino relay module bluetooth upgrade for android control.

Upgrading a basic 1 channel relay module to android bluetooth control.
For small size, im used attiny45/85.

Its works with parseInt, so accept only integers from android.
Im used 111 for turn on, and 222 to turn off, but you can change it.

Used android app:

Using solar charge controller with wall power

I did not have a battery charger for my 9 amp hour battery and using a car battery charger would kill it. One thing i did have in the shop was a solar charge controller.
Will a wall wort power supply be able to replace the incoming power instead of a solar cell?

Raspberry Pi 3: 20 of the finest projects you may try with the minuscule computer

Received a Raspberry Pi 3? Below are 20 wonderful projects to start!

The Raspberry Pi 3 is regarded as the greatest beginning points for employing coding. Whether you’re a first-timer with Python or a tech professional, this micro computer is a fantastically versatile device.

It’s something of an understatement to say that there’s a great deal you can try with the Raspberry Pi 3. Since the first Raspberry Pi premiered in 2012, folks have been putting it to work on projects which range from the helpful to the preposterous. Desire to write your individual gaming applications? Check. Wish to make a smart media centre for your Television? Take a look. Need to breathe life into a memorable children’s plaything? Take a look.

At this point we’ve chosen 20 rewarding projects to sink your teeth into – starting from the hassle-free to the troublesome. These will likewise work for those who have a Raspberry Pi 2, while they might be a a tad bit more complicated if you have the previous Raspberry Pi or the Raspberry Pi Zero.

The 20 best Raspberry Pi projects

1. Raspberry Pi projects: Create a Kodi streamer

Kodi is among the actual most desirable streaming platforms you can get, permitting you to experience local and web-based content on anything ranging from your mobile to an Amazon Fire Television Stick(How-to guide: http://alphr.com/software/1001730/how-to-install-kodi-on-a-fire-tv-stick-the-best-way-to-download-kodi-to-an-amazon). Oh, and it’s also available on the Raspberry Pi 2. If you want to experience the great merits about Kodi, the Raspberry Pi 2 is more than powerful enough, and installing the streaming software package is incredibly direct as well (http://alphr.com/media-centres/1000077/how-to-turn-a-raspberry-pi-into-an-xbmc-media-center-build-a-fully-functional).

2. Raspberry Pi projects: Write your very own game

3. Raspberry Pi projects: Make a GameBoy
No, seriously. It is a appropriate and do-able project for the more professional user. Regarding the actual coding, it may not be the most difficult – you’re essentially adding an emulator on your Raspberry Pi. The complicated work shows up in the sort of soldering the different pieces jointly.

Travis Brown at XodusTech (http://xodustech.com/projects/raspberry-pi-gameboy-pocket) has provided a detailed record of methods he brought his Game Boy back to reality using a Raspberry Pi. The greatest thing about making a Pi-Pocket – as he calls it – is that you’re not tied to playing only GameBoy games; the Pi-Pocket is also capable of playing NES, Sega Master System and Game Gear titles, in addition to renowned Linux-based games similar to Doom and Duke Nukem.

4. Raspberry Pi projects: Build up an AI assistant
5. Raspberry Pi projects: Home Arcade Box
6. Raspberry Pi projects: Media centre for your Television

7. Raspberry Pi projects: Make a wireless extender
Practically nothing demonstrates the flexibility of a Raspberry Pi rather like this project (except for the GameBoy below). With a USB Wi-Fi dongle, a microSD card and the Raspberry Pi itself, you raise the reach of your wi-fi signal.

Guy Eastwood has generated the impressive Pi-Point site (http://pi-point.co.uk/), which can take you through what you need to be informed on this project. Click this link to take a look at thorough documentation and 100 % free downloadable graphics to assist you.

8. Raspberry Pi projects: Create a download hub
9. Raspberry Pi projects: Make a dedicated Minecraft machine
10. Raspberry Pi projects: Make a camera trap
11. Raspberry Pi projects: Build a case
12. Raspberry Pi projects: Manage your stereo wirelessly
13. Raspberry Pi projects: Construct your individual cloud server
14. Raspberry Pi projects: Create a mobile phone
15. Raspberry Pi projects: Build your own PiRate radio station
16. Raspberry Pi projects: Make a wise beer refrigerator
17. Raspberry Pi projects: Create a PiCam
18. Raspberry Pi projects: Create a talking toy
19. Raspberry Pi projects: Create a bitcoin mining system
20. Raspberry Pi projects: A teeny arcade cabinet

PCB Design: Associate PCB Patterns to Schematic Components

If you’ve worked with PCB Creator or DipTrace, you may have noticed when converting your finished schematic to a layout, some of your components have magically disappeared. This happens when schematic components don’t have a pattern layout associated. In this example, I’ll show you how to associate an existing pattern to a component for a simple power/ground wire-to-board connection.

Zero Defects International Brings in Taiyo PCB Inspection System

Zero Defects International [ZDI] has been allocated by Taiyo Industrial Company, Japan, to manage the North American introduction of it’s intelligent printed circuit board final inspection systems. These inspection systems have picked up widespread success in The European Union and in Japan and are right now being introduced to the United States and Canada.

Ahead of commencing this project, ZDI contacted all sorts of PCB producers with the intention to determine if there would be a perceived require for this kind of equipment. The comprehensive agreement was that the product is one that will perform an important function and, as well, offer a very ideal Return on investment.

Recent initial trials in America have proved that the machine managed to uncover defects that passed common visual inspection but should have been flagged as not meeting the end customer’s requirements. Detection capabilities comprise of: exposed copper, solder mask on pads, scratches, foreign material, blocked holes and chipped plating.

About Taiyo Industrial Co., Ltd.

Taiyo Industrial Co., Ltd. created in 1960, is diversified with interconnect and test business interests. Flexible printed circuits are a mainstay along with a number of PCB test and inspection systems.
