Topic: Ideas on making a 1.5 in x 24 in Graphic LCD?
Replies: 27
Views: 7212

Hi,
What pixel density are we talking about here? What are you planning to display, text, graphic or just light effects? Is the 1.5" x 24" the max dimension of the module or the size of the display area? What thickness are we talking about?

Why does it need to be LCD?

Hi JPK,
Oki used to have/has a chip called MSM6322, a pitch control chip for changing realtime speech +/- one octave in 17 steps. Here is the datasheet: http://pdf1.alldatasheet.co.kr/datashee ... M6322.html

This is a stand alone solution.

Robert & JPK I totally agree with you on this, it is of little educational value in electronic theory to make a 95% ready project. From the questions in this forum, I would say that much of the basic knowledge in the electric and electronic world is passed by. You jump from lighting a LED and pushin...

I do subscribe to SERVO, and I like it more and more. The mix of articles is coming around I think. The one thing I would like to see, is a little more and advanced construction & theory, and maybe less of the Lego range of articles. They tend to be long and take up a lot of space. Yeah, I know they...

Isn't this what we call experience? It's never wise to only look at, and base your life on headlines, wherever you see it. I've seen 'engineers' select critical components from shortforms alone, with interesting results like magic smoke and bad air. Shortforms and max ratings are only used to sort o...

Hi All, 1 Top Silkscreen 2 Top Solder Mask 3 Top Copper layer 1 4 Bottom Copper Layer 5 Bottom Solder mask 6 Bottom Silkscreen I don't know if you are into SMD, but if you are, you need to make room for paste mask(s) and placement files.

Hi,
I suppose this is out of question, but I've seen some info on vacuum formed plastic, that seems relative cheap. You may also make this yourself, using a vacuum cleaner and a forming table/ bag.

Hi I receive my volume normally between the 20th and the 27th each month.

Hi,
I think this is rather natural.
If you compare the capacitors with two buckets, one full and one empty, you end up with two half full buckets if you 'connect' them. The total amount of water is the same but the volume is twice as big.

Hi Dacflyer, The AC is a cmos buffer with little input current, the LS is a low power TTL(TransistorTransistorLogic) and draws current on the input. They have both a voltage limit on the output equal to Vcc(5V). If you use a led display with a forward voltage of >=4V you can use this buffer on a 9V ...

Enclosure design links

I've tried to find a site with design examples(drawings/pictures) of enclosures with a panel interface. The panel contains LEDs, LCD and a keyboard/button matrix. I'm in the process of making a feasibilty study of a future product, and need some ideas/ solution input for designing the 'ultimate lowc...

Re: Help ! I am stuck on stupid today..

Hi Dacflyer, I've checked for cmos versions of the 7407, and there are several types you could have used if you use 5-6V as supply voltage. I seem to remember that you use 9V, and that is too high for these parts. If you could reduce the LED voltage to 5V, ther is no problem to get cmos replacements...
