Overview of the Rev.H Clock PCB, ready for production:
There is no version of the LEDclock with RTC and an RTC version will never be developed by myself (the DCF77 version works way too well, even in...
In my previous post I wrote that the demo version of the Sprint-Layout program was sufficient to print out the .LAY PCB files.
This is wrong....
Due to the many demands (here and on other forums) I finally put my DCF77 LEDclock project (after more than 4 years!) available on my webpage,...
BTW, I know this thread is quite old (2006 and more than 300.000 views!), but may I ask if there is still some interest for my 6-digit 7-segment...
The six used tubes came from Ebay.
I got them for the starting bid price (a few $) as incrediblingy (spelling?) I was the only bidder...
Glad to hear from you!
Clocks: Lots of them in the pipeline, but unfortunately not much time left due to other priorities....
Sorry for the late reply.
Where are you from?
My clocks (deliberately) only work with the DCF77 atomic clock signal from Mainflingen, Germany....
Have a look at C-Max receiver IC's
I have a few but no time to play with...
AFAIK, Conrad is the ONLY place where you can get these little modules (#641138-29):
I had the opportunity to buy bigger (and...
The base resistors are included in the 74C925.
See the 74C925 datasheet.
As SteveyG says you can easily fix this with some NPN's in open collector or cascode configuration.
An example here:
See T1 to...
This 4x40 datasheet from Powertip could be useful.
I think the backlight has separate feeding connections as h_2_o's LCD only has 16 pins.
I'm pretty sure 'sn102' is not a model number.
Anyway, it looks to me as a 4x40 LCD (hence the two HD44780's).
The 16 pin connector is pretty...
Sorry, my fault... :rolleyes: On the picture they really look like white displays.
Joseph from LC-Led is a fine man. Once (on all the...
Nice work Stevey!
Where did you source your white displays?
Long time no see.
How are you?
I just finished the PIC software for a 9-digit DCF clock with a IW-18 VFD tube, and also 90% of...
Weird, I got 49 mails in my skynet mailbox this morning... :confused:
The exact syntax is:
turbokeu at skynet dot be or chris dot deceuninck...
Glad to hear from you again.
Didn't know about the reception issues with GPS (the only GPS that I own is builtin in my car).
A great (but expensive!) simulation software is Proteus VSM from Labcenter Electronics.
I use it since about 5-6 years (I...
