Is Delphi for PHP successes ?

I’m trying Delphi for PHP 2.0 in few days back and I'm get very frustrated about it because of its pour implementation and technologies. Some key failures in Delphi for PHP 2.0 are,

- IDE is very buggy and most of the times it produces "Access Violation" errors and IDE get confused. (In my computer Delphi 7 tries to debug it.)

- Help is very pour and incomplete.

- JavaScript and PHP integration is very complex and buggy. Most of the time JavaScript codes may not work in client side and it is heavily depends on the web browser.

- Some times it is necessary to deploy entire "VCL" directory to the web server otherwise some of the VCL components produces invalid outputs. (specially RichEdit and TrackBar components)

- MySQL integration is pour and buggy.

- Build-in Apache web server crash several times and because of that reason we may not be able to debug/run web application using IDE.

- Some times XML file (xml.php) generated by Form Designer may not compatible with VCL for PHP framework.

- Some of the controls have missing properties.

Actually most of these problems are not very critical (we can fix most of them at the work) and hopefully Qadram Software will fix these problems in there next releases but at the moment Delphi for PHP is not a wise investment for PHP rapid application developments (RAD) and I’m personally recommended to use PRADO framework (http://www.pradosoft.com/) instead of Delphi for PHP. PRADO have same features as Delphi for PHP. The only thing is it does not have drag-and-drop style IDE.

Compared with other web application development systems (IDEs) the concept of "Delphi for PHP" is an excellent and it provide complete web application development solution to the PHP, Delphi/C++Builder users, only thing is it need more maturity.

According to my observations Delphi for PHP is not a tool developed by CodeGear (former – Borland), it is developed by Qadram Software and the core of the system – "VCL for PHP" framework is available in Sourceforge.net as an open source free software project, (same as PRADO) so anyone can modify, fix errors or add features to that framework. VCL for PHP is distributed under the terms and conditions of GNU – LGPL (GNU Lesser General Public License), and its competitive framework PRADO is distributed under the BSD Licenses.

Note : If you are a Delphi/C++Builder developer it is highly recommended to use PRADO because it’s naming standards and execution patterns are more similar to Delphi VCL.

CD2003 - yet another simple FM radio receiver

In the last few days, we are looking for some simple FM radio receiver to integrate into one of our ongoing projects. For that, we try several FM radio receiver ICs including TDA7000, CD2003/TA2003/TA8164, CXA1019, and KA22429. Out of all those chips we select CD2003 (or TA2003/TA8164) based receiver for our project because of its simplicity and outstanding performance. Except to CD2003, Sony CXA1019 also perform well but we drop it because of its higher component count. We design our receiver based on Toshiba TA2003 datasheet and later we try TA8164 and CD2003 with the same circuit. Either CD2003 or TA8164 can directly replace TA2003 IC, and as per our observations, TA8164 gives excellent results out of those 3 chips. A prototype version of CD2003 FM radio receiver The PCB design and schematic which we used in our prototype project are available to download at google drive (including pin-outs of crystal filters and inductors ). Except for CD2003 IC, this receiver consist...

Arduino superheterodyne receiver

In this project, we extend the shortwave superheterodyne receiver we developed a few years ago . Like the previous design, this receiver operates on the traditional superheterodyne principle. In this upgrade, we enhanced the local oscillator with Si5351 clock generator module and Arduino control circuit. Compared to the old design, this new receiver uses an improved version of an intermediate frequency amplifier with 3 I.F transformers. In this new design, we divide this receiver into several blocks, which include, mixer with a detector, a local oscillator, and an I.F amplifier. The I.F amplifier builds into one PCB. The filter stage, mixer, and detector stages place in another PCB. Prototype version of 455kHz I.F amplifier. In this prototype build, the Si5351 clock generator drives using an Arduino Uno board. With the given sketch, the user can tune and switch the shortwave meter bands using a rotary encoder. The supplied sketch support clock generation from 5205kHz (tuner f...

Calculator for audio output transformers

Audio output transformers are heavily used in a vacuum tube and some (older) transistor base audio power amplifiers, but these days output transformer are quite hard to find and expensive item. For homebrew projects, the best option is to construct those transformers by ourselves and this script helps to calculate winding parameters for those transformers. This " AF output transformer calculator " script is written using Python and it works with most of the commonly available Python interpreters . The script is available to download at google drive under the terms of GNU General Public License version 3.0 . Homebrewed 25k: 4 output transformer Once supplied the input parameters this script provides a winding ratio, the number of turns required for primary and secondary winding and required copper wire gauges for both primary and secondary windings, etc. We construct several AF output transformers based on results of this script, which including transformers for M...
