@@adilagou6772 kool, ill look into that, thanks! I could probably do my pcb tutorials on there.

@@adilagou6772 yeah, i could do that.😎 Email me and ill let you know some ideas.

@@massimookissed1023 exactly!! You toggle the sain pin, take a reading, toggle it again and take another reading, etc until you get all 7 bands. Then do a reset and retake the 7 readings over and over again😎

@@massimookissed1023 on the final pcb im going to have all 7 bands on display

@@massimookissed1023 thanks for watching.

@leilanielectronics It wouldn't be too hard to have a 2x 7-band displays, 1 left, 1 right. The MCP3008 has enough channels to read 2 MSGEQ7s, or the PIC could sample them itself. A 10-LED bar doesn't need higher bit accuracy than the PIC's internal A2D can handle, and the AS1115 (or MAX7219) could drive 7x 8-LED bars. (7x 9-LEDs if you want to write code to distribute 63 LEDs across an 8x8 matrix.) ICs like the HT16K33 can drive 16x8 LEDs, easily enough for 7x 10-LED bars.

@@massimookissed1023 yup, you could do it that way but i didnt want to over crowd the face of my boombox so i decided 7 was good enough.

@@unkelib4391 the breadboard is a little noisy with all the digital and analog signals. The final pcb will eliminate all that. Thanks for watching..

@@unkelib4391 i ordered better speakers from partsexpress to go in the final boombox.. these speakers are my test speakers i use for most of my analog projects

@@Stefano91ste 😎😎let me know how it works out.

@@fragmentsofknowledge2142 g.m Im using a 74191 up/down counter connected to a 74154 1 of 16 decoder. leilanielectronics.com/schematics You can print the schematic in pdf from my website.. thanks for watching!!😎

@@fragmentsofknowledge2142 the top circuit is a 0-99 counter, also on the website😎😎

@@AnImaginationstudios44 it came with a cd that i still have, thank god i kept it! As far as buying one, im not sure... maybe check on ebay...

I have no idea what ur doing but good job 🙂

@@snotkop75 i designed and built my own boom box. I got the idea from these bump box radios that are popular now. I added a RGB display with a graphic eq and analyzer. 30w, 6 speaker output, BT and aux input. Ill post the schematic on my site when im done with the pcb.

@@snotkop75 it also has an am/fm radio for those who still listen to the radio😂🤣

This is an amazing circuit!!!

@@KingYuna-r6e you ll love it! Www.canamspyderf3s.com

@@Enigma758 i have to find out the company logo of the two and then maybe email them.. im not given up! Ill find out and do a project with them😎👍🏾

@@Itsprabh124 they stop selling 2ways about 20 years ago.. i had two of them, loved it! Thanks for watching!

@@q12x thanks for watching😎 The 2 diodes drop the voltage to each display to around 3.6v to prevent damage. I didnt use a resistor because both of the drivers have internal current limiting outputs.

R3, R4 and R5

@@leilanielectronics Interesting, you should have mention this detail in your movie....but...I still don't get why you had to lower the voltage with those diodes ! And what is the output resistance of your driver ? 1k I assume?

@@q12x the displays can only handle around 3.3v, maybe 3.8v max. So the diodes drop the voltage down to a safe level. Again, no need for a resistor because the lm3914 and stp drivers have built in current limiting for the outputs.

@@q12x r3, r4 and r5 set the output current for the displays.

@@Enigma758 FeCl? The etching liquid?

@@leilanielectronics Yes, ferric cloride for etching. It's dark brown and if you come in contact with it, it will stain your skin (for awhile).

@@Enigma758 ok, yeah, thats the bottle in the kit.

@@makerjeff86 i always wonder how many they sold... probably alot..!!

@@jonnymakers9560 thanks for watching!

Thanks, im almost done with the a.m function😎 Stay tuned!

I got receipts dating back almost 30 years, im afraid to add up😂🤣😅 But i will one day. Its an expensive hobby. Thanks for watching

There are 4 appnotes: an383, an388, si47xx programning guide and the an332. The an332 is the one needed and most helpful in getting the radio up and running. The other 3 i skimmed thru for now but should be helpful later, good luck!!

Awesome , thanks!!

@@will85iroc Excuse my ignorance, but what is "appnotes"?

​@@mustafaiqbal89most manufacturers have applcation notes (app notes) in addition to the datasheets. They give circuit examples, how to's, programs, etc to help the user get the device running. Silabs has a few for the si4732 that shows antenna set up's, pcb layout and other stuff. The appnote for the programming is a must to get the chip running. Thanks for watching!!

​@@mustafaiqbal89i have them all in pdf, if you need a link let me know... but you can search on silab website

This chip does alot! Once im done with the fm, ill test the am, lw and sw then make a permanent pcb with touch screen OLED to control it. Thanks for watching..

This is only a fraction of what this chip can do! There are 3 app notes that are great and a 188 page programming guide that im sifting thru..

The stp08 and the stp16 are 8 and 16 channel led drivers. Output current is adjusted by a single resistor. For this circuit current is set at 20ma. Thanks for watching!

Thanks for the tip. I got the displays from Adafruit and yes they are a little expensive but they make a cool project!!

Yup, radio shack!

The stp's are excellent! Been my goto drivers for years! Thanks for watching.

Program will be posted soon!

Updated correct link.

Glad you asked😎😎im posting a whole video for that circuit this weekend. Its a digital rgb clock and those rgb led's are made by Adafruit. Be sure to visit the site on sunday and download the schematic! Thanks for watching!
