The key benefits of choosing PCB assembly services from NextPCB

PCB manufacturing has changed over the years. The customer side usually performed most of the designing, prototyping, assembling, and testing. Controlling the production and quality of all steps requires significant expertise and resources only larger companies can allow. Large electronics manufacturing companies have different access to technologies and have been using them for a while. What about smaller ones and even hobbyists? The successful cases were backed by enthusiasts who were great at designing circuits, tracing PCBs, and testing. No matter how good you are, you cannot do all work fast and well enough to play on the market. Therefore, IT services play a vital role in an individual’s daily routine by providing them with a smooth technology experience. Continue reading

Seeedstudio Fusion Vs Elecrow Vs JLCPCB

I have been building these small projects for quite some time now and used a lot of PCB building services. Professionally made PCBs brings in a lot of advantages, the one I like most is that I don’t have to get rid of the etching solution after – oh I have to mention the silkscreen and solder mask finish that you won’t get from DIY PCBs. The professionally build PCBs generally performs better than DIY PCBs. I have used these services in the past – let’s look at them in detail and see which service you should apply for your next project. The first part that we should look at is the order screen and the options they offer. Most DIY projects would only go two layers but for those who need complicated layer stack up and shielding JLCPCB offer up to 8 layers while Elecrow and Seeedstudio offer up to 6 layers. In terms of material, Seeedstudio has the most offering having FR4, Aluminum and Flexible Boards while JLCPCB only has FR4 and Elecrow didn’t state so I would… Continue reading

The Colorful Mechanically Scanned LED Display

Is anyone here a big fan of the propeller clocks? Isn’t the logo that flashed out from the high spinning propeller clock fascinated and mesmerized your heart? So, what do you say? Do you want to build a mechanically scanned LED Display, which is having the same effect as the propeller clock did? Sounds interesting, isn’t it? Well, the PCB is the main part of this project. It contains: The PIC microcontroller, Four HC573 latches, Five ULN2003A 7-fold darlingtons, A power supply stuff, A MOSFET (It is to drive the first motor) Two push buttons (They are for setting the date and time). Beside that, you need to use an LM317 adjustable voltage regulator for LED brightness control. Also, make sure that the main power supply should be at least 12 volts, as the ball bearings don’t always conduct perfectly. What is so unique about the mechanically scanned LED display is it can act like: An analog clock (It displays in seconds, minutes and hours form). A digital clock (It has the time, weekday, date and year form). A 64×32… Continue reading

The Finest Combination of LCD and USB – LCD2USB!

Most of you here were very familiar with the LCD and USB in your daily life, but have you ever thought to combine these two different components into a cooler gadget? Yep, the gadget that you’re going to develop is LCD2USB! This LCD2USB is an open source project, and the main goal of LCD2USB is to connect HDD44780 based text LCD displays to various PCs via USB. The advantage of this LCD2USB is very cheap and easy to be developed. Since the project is based on the Atmel AVR Mega8 CPU, hence it doesn’t require any difficult to obtain parts, such as the separate USB controllers. The total cost without display and PCB are less than $10, which it is extremely cheap if you comparing with those on market! Furthermore, the LCD2USB is currently comes with a simple demo application, which allow it to work under Linux, MacOS X and Windows without any further medication! The LCD2USB is also supported by LCD4Linux (LCD2USB support is built-in), LCD Smartie that require a separate driver and LCDProc (LCD2USB support is currently in… Continue reading

The Atmel STK500 EVB – The Marvelous Component For Arduino Development Board!

The Atmel STK500 EVB is one of the most incredible starter kit development system features ISP and high voltage programming (HVP) for all AVR devices, which it can be either directly or through extension boards. Most of the time, the board is fitted with DIP sockets for all AVRs that available in DIP packages! Today, you’ll have the opportunity to see and learn how to configure an Atmel STK500 as an Arduino-based development system board. You must be wondered, “Why you have to use the STK500 instead of a real Arduino PCB?” Well, no one said you could not use it here, unless you already had it and the board carries eight switches, eight LEDs and a variable, software programmable AREF voltage as well as a variable power supply! When you’ve done with this project, you will have an STK500 running Arduino with the added advantage of pushbutton, LEDs on board, variable power supply and variable Analog Reference (AREF). Note: You must pay attention that the AREF short pin must be carefully inserted when the on-board voltage reference is to… Continue reading

DIY a Dual Trace Scope By Your Own and Save Enormous of Money!

As we all knew that the currently worldwide economy has been moved in the downward position and most of the countries all around the globe have been seriously affected by this economy crisis. It’s getting hard and harder to earn our living and that’s why you should learn how to save as much of money as you can! However, some of you may think that it’s easier to be said than done… Well, guessed what! Would you believe if you could develop the cheapest dual trace scope with a cost less than $8 per unit? It seems unbelievable but this is the fact! For your information, this submini USB dual trace scope is based on Atmel Tiny45 CPU and it’s a homemade PCB. It has two analog inputs and can supply 5V onto the four pins header on the right. Beside that, one of the inputs can be scaled down with the trim pot. Instead of the low development cost, this dual trace scope’s size is about a credit card and it’s a very cute and compact component as well!… Continue reading
