Spectral Clock - Propeller Clock

there is no AVT in AVT; / I can not find a store that would offer the availability of all these chips; /; / I think I'll be fine with the taste; /

The motor driver can be found on the disc, the only thing you need to order are the MBI systems. In the warehouse mentioned above, they can be purchased for quite an affordable price.

Regards

takk with some drivers from disk may be a problem, hmm, but still the RTC chip remains; /; / it will be hard; /

You can replace the RTC system with the very popular PCF8583 which also runs on the I2C bus, of course, after appropriate modification of the program and PCB
Changing the software just in the part responsible for the correct reading of the time from the RTC should not be difficult.

Exactly! The PCF is generally easy to get, and as for the driver: because I would also have problems with desoldering it from the board, I decided to leave this chip in its place and connect the motor as it worked in the original.
solution. Maybe there are any other drivers besides the unfortunate TDA?

hmm, I don't change the program, I'm completely green in it; d

Then maybe wait until one of my colleagues or I, because I will be making such a watch, will make it on more available parts
And I'm just going to be at the stage of looking for a driver for the engine and either I will find one that is reasonably available or I will construct something Oh, and the contactless power supply will also be a rotating transformer
Only due to a slight lack of time due to a lot of work, my project may not be created so quickly

Traax Maybe you should look for a more affordable one
project? For example, with a smaller number of LEDs, then the problems with their control would be eliminated, the same if you could use a different motor in such a project, e.g. from a fan
and you don't have to worry about hard-to-reach drivers. There was probably such a project on Elektroda. Just something I can't find it .....

hmm, I don't like those clocks. for me this one is perfect. you will have to look for ...

You have the drivers here:

LED drivers, Atmega and ds1307 in one store.
A bit of a shipment will come out a lot, but what can you do about it.
If you want this watch, there is no other option.

(I stated the shops but I do not advertise them)

how neatly in this andpol, almost everything and the shipment only PLN 10; d one problem with this page, where is the price given ??

You should send an inquiry with the price and whether the goods are available

So we are waiting for a pattern, but so for peasant reason

well, I predict that in June my project will be ready, so I'm waiting for a free flow of cash And it will definitely appear on the elka

Hehe, it's still me, to be honest, I was going to go a little bit down, I thought about max. 2 months and here is a friend traax writes about June
But the most important satisfaction with self-performance and, of course, the final result

The design is great.
I will buy some elements and deposit such
and then I will struggle with my own project.
I think I will get there by the beginning of May

Hello, I have a problem, I know the basics of assembler, but in C I'm completely green. Can someone help me what to program, what changes in the program to do (because when I compiled on WinAVR, errors popped up) etc. link to the author's program: https://www.elektroda.pl/rtvforum/download.php?id=285142 " target="_blank" rel="nofollow noopener ugc" class="postlink inline" title="" > https://www.elektroda.pl/rtvforum/download.php?id=285142
how to write on gg 10587682

Hello

At the beginning, a very great respect on my part :)

I mean, I don't really know what you describe here and the watch is great. It would be advisable for me to buy the same clock from the author of the topic. ??

If so, what will the price be?

Regards

Marcin

You should deal with such matters on private. But since you are asking, this clock is unfortunately not for sale. It has some technical shortcomings for which I do not want to be held responsible later. Besides, I will need it in the construction of the final and probably the last version. It will be a much more serious project and the results should be expected in the summer.

hi everybody. this circuit really very nice and We want do this but we dont know your language. How do can do this circuit in english language?Can you translate please. İf you can do this.Really we will happy:D

THANKS to DJ_WEST for english translation. Thank you DJ_West.

Or maybe someone provide a list of parts and the pattern of the plate ??

Hello

In the diagrams (in the PDF version) I can see that 4 MBI5170 - 3 in the 8 bit version and 1 in the 16 bit version are designed. Is it a distortion or does it have any significance for the operation of the system

I am joining the request for a "list" of parts - what I have deduced a bit from the description and the diagram, but it is about "exact types" because the MBI has several variants:
MBI5170CD SOP16-150-1.27 8-bit
MBI5170CDW SOP16-300-1.27 8-bit
MBI5170CP SSOP16-150-0.64 8-bit
MBI5170GD SOP16-150-1.27 8-bit
MBI5170GP SSOP16-150-0.64 8bit

and there are still 16 bit versions :)

The same with Atmega32 - SMD version, but the exact type, unless it does not matter and it will be as long as the housing is TQFP44 and for MIB SOP16

Request also for a list of passive elements

Thanks in advance

Hello dear colleagues. I am just at the stage of soldering the board and completing the mechanical system and here I have a question for the constructor: how is the board connected to the motor? ie is it only on three screws? I will try to cut the disc from the CD (because it fits the upper diameter of the shaft) and stick it to the plate. The next problem is a slightly different spacing of the mounting holes in the engine (I only have 3 threaded ones) and getting fi2mm screws and the last problem - battery mounting (is it soldered? Or in the stand) because the photos show poorly. And a piece of advice for followers - the paths on the bottom layer can be made thicker and some jumpers can be made differently. I would also like to learn about other disadvantages mentioned by the author, as well as the idea for the final version. I bow to the author and greet him

Hello everyone.
Sorry for the delay, but for some unknown reason the notification of new posts has been disabled.
The plate is adapted to a specific engine from the seagate barracuda disk, it has 5 holes that perfectly match the holes in the engine housing. The spacing of these holes is not standardized, so other manufacturers use different dimensions. If you use a motor other than the one described, the holes must be adapted on your own. In my clock the propeller is attached only to two 2mm screws, it is enough.
The battery is placed in a socket which is soldered to the board. This stand has been removed from the cell key fob, which flashes when ringing. In turn, I took the keyring from my little cousin .
The main disadvantages are the lack of external communication and, of course, energy transmission via brushes. A coreless transformer will be used in the final version. However, the biggest step will be the use of tricolor smd diodes and an FPGA chip from the SPARTAN family. Perhaps it is too powerful a system for such a device, but I treat this project in terms of development.

welcome back,
these holes are a lot of trouble . I had to move the holes a bit and drill to fi3. Motor material is nasty to machine and won't thread - I'll have to paste on the distal when finished. But that's not what I wanted to do. I have just finished soldering and I am faced with a programming problem. I have a double problem because I have an atmega but 16 and I know the basics only of bascom. The batch is supposed to be, but how to handle it ???
let's say I manage to program but how do you set the time, etc.
I am asking for help here on the forum because maybe others will also need it.
greetings

Hello. I have a question, what is the setting of coffee grounds in prock ??

external quartz set at 16Mhz

I recommend reading http://elportal.pl/index.php?module=ContentExpress&func=display&ceid=243

The plate has already been soldered, the motor is temporarily mounted in a stand made of a cd box and the top serves as protection. Everything is spinning nicely now . I also wrote a skeleton program in Bascom (great training because I'm just getting started) and it actually works but the algorithm sucks a bit. Because timer1 (16bit) counts the clock cycles from the INT0 interrupt (IR sensor that determines the starting point on the dial), then this value is divided into 240 and timer0 is loaded with this value, counting the individual steps of the pointer - but dividing by 240 causes the rest and the rest to arise causes the hands to vibrate. I've been struggling with this for a while and come to the conclusion that I need a different algorithm, or more accurate division. Does anyone else do practically this layout?
greetings.
