Comments Off on Thaikits – Electronic Kits for Learning

A group of test engineers in Thailand who worked in an Electronic factory more than 12 years have started a small business to sell electronic projects and electronic kits worldwide in 2007.

Comments Off on Homebrew Projects – Laboratory of Changpuak

The Electronics section of Changpuak maintained by a Teacher of Thailand, Alexander C. Frank, has calculation tools for electronic circuits as well as some electronic projects like power supplies, signal generators and curve tracers too .

Among others they also have Amplifier Design, Antenna and Filter Designer AF and RF and Basic Electronics Tutors.

A Geiger-Müller tube consists of a tube filled with a low-pressure (~0.1 Atm) inert gas. (Helium, Neon, Argon,…). The GM-Tube has a coaxial shape, where the inner conductor (Anode) is biased with a high voltage (~500V) relative to the outer conductor (Cathode). The Tube has a window (left side) made of mica.

This GM-Counter is build on 2 PCB’s. One is a standard high Voltage generating circuit, whilst the second is a Counter based on an ATMega16™ which also handles serial Communication with a host (Environmental Control).

This website conserves all those nifty little mini-projects (gadgets) which were developed to enhance the doctoral hats of our “fresh” doctors.

delabs Notes

Doctoral hat electronics – After seeing this section i am convinced that the next innovation will be “SmartHat”. There is ample space in a cap for an Advanced Android Multimedia Gadget with a Hepta Core ARM chip and all the works. Rush to the patent office !

These pages created by Wichit Sirichote of Department of Applied Physics, Faculty of Science, provides schematic and software for hobbyists to practice “learn by doing”, build a simple microcontroller projects at home.

Some of the projects include – The 4 Channel Pt100 Thermometer, G5-Data Logger, Solar Recorder, 89S52 and PIC Project Board. Even circuits, code and SBC for the popular 8051 can be found here.

I do remember the Intersil ICL7135 very clearly. This year 2011, almost 29 Years, the classic integrating type analog to digital converter is still interested. With a cheap price and easy interfacing, I think I will design a cheap digital volt meter with microcontroller to provide serial interface similar to the Fluke45. Two channels is good for scientific experiment. The serial port RS232 is also nice for interfacing to the PC. Let us see the prototype of the meter in Figure 1. The display for each channel is 8-digit 7-segment LED. It is cheap and very reliable.

This was a Student Project of mine, it is a very basic instruments that could do most of the tasks on a test bench.

The cabinet used, was available as a part of a Hi-Fi DIY System, The Range and Mode switches were Modular Stackable Interlocked MultiPole Switches. The rest of the Interface were wirewound pots, jacks, sockets and plugs. The front panel was Engraved Acrylic, the panel was the toughest issue we tackled.

I wanted it to look well engineered, at least on the outside. It was a total analog instrument except for the digital indication of ICL7107. Thanks to ‘Intersil Hot Ideas’ Applications Book.

The above belong to an instrument Measureall shown below.
