Seeed Studio Grove Arduino Starter Kit

8/7/2019

Comments

Grove is a modular electronic platform for quick prototyping. Every module has one function, such as touch sensing, creating audio effect and so on. Just plug the modules you need to the base shield, then you are ready to test your idea buds.

This Grove - Starter Kit for Arduino is a perfect starter kit for Arduino begginers. It includes a Base Shield which have many Grove connectors on board, twelve Grove modules that covers most functions needed by a begginner and a very helpful user manual that can help get started quickly.

Buy if from here: https://www.seeedstudio.com/Grove-Starter-Kit-for-Arduino-p-1855.html

Arduino Uno is the most popular Arduino board so far, however it is sometimes frustrating when your project requires a lot of sensors or Leds and your jumper wires are in a mess. The purpose of creating the Grove – Base Shield is to help you getting rid of bread board and jump wires. With the rich grove connectors on the base board, you can add all the grove modules to the Arduino Uno very conveniently!

Buy it from Seeed Studio: https://www.seeedstudio.com/Grove-Starter-Kit-for-Arduino-p-1855.html

In the box you will find:
-Base Shield
-Grove - LCD RGB Backlight
-Grove - Smart Relay
-Grove - Buzzer
-Grove - Sound Sensor
-Grove - Touch Sensor
-Grove - Rotary Angle Sensor
-Grove - Temperature Sensor
-Grove - LED
-Grove - Light Sensor

Μία γρήγορη ματιά στο Raspberry Pi 4

5/7/2019

Ένα νέο, πολλά υποσχόμενο μοντέλο

Το Raspberry Pi 4 έφτασε πλήρως αναβαθμισμένο, ταχύτερο και αποδοτικότερο. Ένα νέο μοντέλο που αναμένεται να γίνει ο νέος σου επιτραπέζιος υπολογιστής. Η ταχύτητα και η απόδοση είναι τα δύο πιο σημαντικά στοιχεία που διαθέτει ο μικρο-επεξεργαστής. Πιο συγκεκριμένα μιλάμε για μία μνήμη RAM που βγαίνει σε 1,2 και 4 Gb ανάλογα με την έκδοση που προτιμάτε.

Συγκριτικά με το προηγούμενο μοντέλο δείχνει να έχει επενδύσει σημαντικά στο θέμα της τεχνολογικής εξέλιξης. Πιο αναλυτικά τα χαρακτηριστικά του είναι ως εξής:

Επεξεργαστής: Broadcom BCM2711, 4-core Cortex 1.5 GHz
Μνήμη RAM: 1, 2 και 4 Gb
Bluetooth 5.0
Ταχύτερη κατά 10 φορές μεταφορά δεδομένων με 2 θύρες USB 3.0
2 θύρες USB 2.0
2 micro- HDMI για υποστήριξη ανάλυσης ακόμα και 4K !
Τροφοδοσία 5V με USB Type-C
Με την παθητική ψύξη μπορεί να λειτουργεί σχεδόν αθόρυβα καταναλώνοντας χαμηλή ισχύ.

Κάτι που μας έκανε εντύπωση είναι όπως είδαμε και στα χαρακτηριστικά υπάρχουν δύο θύρες micro-HDMI που υποστηρίζουν ανάλυση 4K. Οπότε αν διαθέτετε οθόνη μεγάλης ευκρίνειας δεν θα έχετε κανένα απολύτως πρόβλημα. Φανταστείτε να το χρησιμοποιήσετε ως TV Box και να βλέπετε ταινίες σε 4K ανάλυση ή να μπορείτε με την χρήση κάποιου εξομοιωτή να παίζετε παιχνίδια χωρίς αυτά τα σπαστικά κολλήματα. Και μόνο στην σκέψη το κάνει άκρως εντυπωσιακό ! Σίγουρα όμως δεν θα λείπουν και τα ελαττώματα . Θα θέλαμε να μας γράψετε κάτω στα σχόλια αν αντιμετωπίσατε κάποιο πρόβλημα με το Raspberry Pi 4.

Με λίγα λόγια μιλάμε για ένα πολύ γρήγορο, χρήσιμο αλλά και αποτελεσματικό Raspberry Pi που δεν θα λείψει από κανένα "έξυπνο" σπίτι.

My custom PCBs based on Arduino

3/7/2019

Comments

The last two years I have made a lot of custom PCBs based on popular Arduino UNO board. For the electronic circuit schematic I am using the online platform EasyEDA.com. I really like it because it’s open source and you can easily find footprints for electronic parts and modules. You can also generate a PCB schematic and produce your own Arduino based board.

If you want to make a cheap but a very good quality PCB board, then you will have to use the JLCPCB.com! You can prototype your own double layer PCBs from only $2 ! The color selection is completely free!

As the JLCPCB is a professional PCB manufacture, it provides you a lot of options such as the type of surface finish, pcb thickness and laser stencil for your SMD designs.
