You actually put that together very well and you did the light sensor very well flush to the board, very well done. Some videos stick the light sensor out the same hole as the thermistor but no need as it is a clear case. One thing you did forget though and everyone else who has made one of these had all forgot one thing. The defuser membrane that fits over the 4 digit tube is actually a sticky back membrane, It takes a while to get the backing off as at first glance you would not realise it is a sticky back membrane but I assure you it is. Peel off the back and stick it on the 4 digit tubes and press firmly as to get all the bubbles out and job done and looks so much better. After you have stuck it on then you can clean it and clean the front bit of perspex inside and out and it really looks the dogs dangly bits. Don't forget to take off the protective film first from the 4 digit tubes before you stick on the defuser.
Thanks for posting this video. I was looking at one of these on BG and it's nice to see how you could go about soldering all the components onto the PCB!
Nice one..i'm going to buy this kit today.. as my first soldering project..was thinking of getting the Hourglass kit to start of with. but thought i don't want to spend 50% of my $$ on something i can't use would much rather grab two of these.. just hope i don't mess up as a noob.. 30+ noob hahah
I done everything but my one isnt working everything is flush onto the pcb and it still doesnt work i applied the right amound of solder onto each solder pad can someone pls tell me why
Is it possible to disable the temperature ? I don't want it cycling through multiple display functions, JUST the clock display... so it would ALWAYS show the time of day.
I would like to do that myself but maybe someone will know a way how. It is possible to show the temperature all the time by just pressing the bottom button once but not so for the time. There must be a way to do it. Maybe take out the thermistor will cure it??? It is worth a try. Let me know if it works I will do it on mine lol.
Various different display modes are possible by connecting either or both of pins 6 and 7 of the microcontroller to ground or + 5 volts. I don't know what all the different options are but if you connect both pins 6 and 7 to ground you will get just the time.
thats the temperature diode so its best sticking out of the case for a more accurate temperature if you dont want it sticking up like that you could always solder it inside the case or dont put it on at all
-1- is day of the week, 1 being monday its a cheap kit, doesn't do 12 hr time, nor does it do farenheit. Im also trying to figure out how to turn the damn alarm off.
This is a commercially available product on the internet, the microcontroller PIC has been programmed and loaded. if you have circuit diagrams without programming code programs available, there is no effect
Manual shows full circuit diagrams, but what Dang Dung said is correct..it won't work without firmware.
