As a result of ongoing effort our website became mobile friendly or, using the trending words, ‘it has a responsive design’. The blog is still readable even on devices with very narrow canvas and should look reasonably well on Android phones and iPhones. In addition to that, now there is a QR Code of the […]

Silicon Chip August 2015 Silicon Chip Magazine – Editor’s response Silicon Chip Magazine – Editor’s response continuation […] It is time to test our revisited VFD PSU in real life. We are going to build a quick prototype using a PCB from MVFD 16S7D Panel with minimum components loaded. All we need to solder is a VFD controller IC2 (instead of HT16515 we are going to use PT6315 as they are pin-to-pin compatible), […] We are continuing our experiments with an alternative VFD power supply which we started some time ago. The high voltage part remains pretty much unchanged for now – it is an inverting regulator based on inexpensive chip MC34063. Excessive current consumption (60-70mA) in idling mode is still an issue but we are not going to […] Let’s make something more complex using Luminardo, a Bluetooth dongle, a OBDII translator ELM327 and a 128×64 pixels graphical monochrome OLED display SSD1306. The plan would be to utilise USB host functionality to communicate to ELM327 via SPP interface and represent such parameters as engine RPM, vehicle speed, battery voltage, remaining fuel on a display. […] As the headlining in our Toyota Camry 1998 was deteriorating we decided to do something about it. But instead of rushing to the nearest auto upholstery/motor trimmers we tempted to do it ourselves. What does it have to do with electronics, an attentive reader would ask. Well, if we were going to deal with roof […] Some time ago we began looking for alternative displays for our Luminardo project and got inspired by a DIY OLED interface board. The author found cheap monochrome OLED displays on Ebay, designed an interface board and wrote a C library. In addition to that some more information on driving such display type was found at […] Just recently we faced a problem when in order to lock/unlock doors of our Toyota Camry 1998 with a keyless entry remote we virtually had to be… inside the car as the remote’s effective radius shrank down to about 200 mm and even less! To make it worse, every subsequent button press led to even […] The prospect of having high speed communication channel between an embedded project and outer world is very tempting. The challenge can be addressed by using a WiFi module in those areas with WiFi coverage being available but what if it is not an option? Then there is no other choice but GSM (also referred as […] |
