VFD MagiClock Laser Cut Enclosure

To give any electronic project a neat look it is always very important to put it in an enclosure of appropriate sizes and shapes. Our VFD clock is not an exception and also needs a box. There are at least three ways to do so. First is to find something off-the-shelf. This is probably the […]

VFD Panel: Building Clock+Thermometer

Now when we have full control over VFD display, it is time to build something meaningful. How about remotely controlled clock with temperature sensor? Boring? Well, it will be unusual device: capable of working from virtually ANY type of remote control, with display activated by a motion sensor, with capability to log current temperature to […]

VFD Driver Demo

In order to control DP501 HNV-07SS61 VFD in an effortless and efficient manner the following software driver has been implemented. The functionality is encapsulated in HT16512.cpp and HT16512.h files and designed for AVR processors. To drive communication interface the logic uses PinMode and DigitalWrite functions provided by Arduino low level library. Also new HT16512 class […]

A DVD Player Hack

Vacuum fluorescent displays (VFD) make any consumer device looking eye-catching, compelling and unusual. A VFD emits a very bright light with high contrast and can support display elements of various colors, some of them are capable of rendering not only seven-segment numerals but characters and even graphical information. VFDs are equally great for anything from […]

DefendLineII & GSM Module in action

Here is a demonstration of DefendLineII project working together with GSM/GPS Module.

GPS/GSM Module. Software support

Module software support includes GSM module library and an example of its typical usage for ATMega microprocessor family written in C/C++. The logic of interaction with SIM900D modem is enclosed in SIM900Modem.c, SIM900Modem.h files and relies on enhanced version of HardwareSerial class originally designed for Arduino project. As SIM900Modem.c does not depend on AVR specific […]

GPS/GSM Module. PCB Component Layout

Components are soldered on both sides of the PCB. Only components that need to provide the required functionality should be soldered. Depending on your situation, some components such as CONN1, CONN2, CONN4, CONN5, L1 etc can be soldered on either side of the board. There is no strict sequence for soldering but U1 should be […]

GPS/GSM Module. Circuit Diagram

The GSM part is based on SIM900D GSM module. SIM300DZ has the same pin layout and designation so it might be used as a replacement of SIM900D. Q1 transistor, R2, R3 and R4 resistors are used to drive LED1 ‘NET LIGHT’ which indicates module networking status. CONN4 is a SMT antenna connector. Q2 transistor and […]
