The ArduClock continues (albeit very slowly)..I have fitted a Dark background LCD display (from eBay) – I think it looks better: still haven’t put it into a box yet.
new LCD Display
I am working on another clock/counter with 7 segment LEDs (HDSP-7503) High Efficiency Red – 7.5mm (0.4 inch) Char Height.
(I bought a lot of them recently) plus some huge 16 segment LEDS – see pic below..
LED size comparison
some changes have been made; the Arduino NG has been replaced by a BBB Rev D (atMEGA168); the LM75A by a DS18B20 and the display is now a 4×20 LCD unit. The Code needs some more work before posting…I now need a bigger box to put it into! I have a nice wooden box that used to contain code wheels, but it’s not quite big enough for the LCD display..
ArduinoClock - version 2!
Just using some bits and pieces, to prototype a desk clock/calendar with thermometer. So far we have an Arduino NG with a DS1307 RTC and a LM75A thermo sensor chip. The Clock/Calendar is working…
the proto layout...
Note that the “Temp:” has no value yet. I may rearrange the display to fit a 16×2 display better. Nearly all the bits are from eBay…
At long last, the more elegant programmer has been completed in a little box (pic to come..). It works well with the ICD2 clone PIC programmer. I have had to reburn the code in the 16F4550 on the programmer twice – XP got the hump and refused to recognise the ICD2 device as a legit. USB device! so the 16F4550 was plugged into a little JDM burner and hooked up serially to WinPic800 which put the right software back..
Now for some 16F877 PLCC hacking!
I have built a temporary PLCC programmer for the 16F877. The commercial adaptor had a short circuit on the power line. My version has power, ground and the programming lines only.
