2D28 Touch Sensor Module Capacitive Touch Switch Module

 This is jog type capacitive touch switch sensor module based on a touch detection IC TTP223B
. 

Normally, the output is low level(at mode of low power consumption). When the finger touch the corresponding location, output will be high(at quick speed mode). When the module do not be touched for 12 seconds, the mode would switch to low-power mode. It can be installed in the module, such as plastic, glass, non-metallic material surface. But not cover thin sheets(metal) on the surface of the module. Just touch the correct position, it can be hidden in walls, desktops and other parts to be buttons. Allows you to remove the troubles of conventional push-type buttons.

Feature:

Low power consumption
Can replace the traditional key
With four M2 screw holes, easy for operation

Specification:

  • Operating voltage: DC 2.0V ~ 5.5V
  • VOH: VCC 0.8V
  • VOL: VCC 0.3V
  • Sink current: 8mA @ VCC = 3V, VOL = 0.6V
  • Source current: -4mA @ VCC = 3V, VOH = 2.4V
  • Response time: 220ms (at mode of low power consumption) and 60ms (at quick speed mode)
  • Size: 24 x 24 x 7.2mm

Transistor numbers and codes

Most transistor markings follow one of these codes: JEDEC, JIS or Pro-Electron. For ICs, look for known numbers (e.g. 741, 4001, 7400) between the prefix and the suffix. Don't confuse it with the date code. ICs typically have two numbers: The part number and the date code. 1. Joint Electron Device Engineering Council (JEDEC) These part numbers take the form: digit, letter, sequential number, [suffix] The letter is always 'N', and the first digit is 1 for diodes, 2 for transistors, 3 for four-leaded devices, and so forth. But 4N and 5N are reserved for opto-couplers. The sequential numbers run from 100 to 9999 and indicate the approximate time the device was first made. If present, a suffix could indicate various things. For example, a 2N2222A is an enhanced version of a 2N2222. It has higher gain, frequency, and voltage ratings. Always check the data sheet. Examples: 1N914 (diode), 2N2222, 2N2222A, 2N904 (transistors). NOTE: When a metal-can version of a JEDEC tra...

Ring tester

 In my Electronic repair job I found normal multimeter is somewhat limited  in certain area. so special tools are needed for saving  a lot of time  Ring tester is one of this kind .helping me to check small hi Q inductors SMPS transformer, TV Deflection coils ,LOT ,line driver transformer and almost any inductor working on hi frequency.Normal multimeter can only identify a open coil ,but not a shorted windings.  I found some commercial available ring tester. but it is not available in local shops of my area.also it seems priced high. So  I decided to make a ring tester of my own. Below is the one I successfully made from the junk box components. I found it very useful. and now it is one of my best test tool collection. Two Ic's, few LED's ,one plastic container and few resistors  made this wonderful tool. If we test it with primary of SMPS transformer or LOT windings of a good one shows all its LEDs will light. depending on the inductive reactantce...
