Aurora 48 Kit
Aurora 48 is a compact and thin profile full LED sequencer. It’s built entirely with surface mount components, so the profile is nice and clean.
Please review the instructables before purchase – assembly requires some skills. You will also need PIC programmer such as PICKit 3, ICD 2, ICD 3 (PICKit 2 doesn’t work with the PIC used). If you don’t have a programmer, you can purchase the PIC programmed with the latest firmware. (The PIC will be soldered to the PCB)

I have the kit ….. I’m having trouble determining the orientation of the 74HC238.
The parts placement shows a notch on one end. Mine seems to have a notch on both ends (on the mold line between upper an lower halves of the encapsulation).
I can see no other obvious orientation marks other than the ID number and other marking is all towards one end.
How can I tell which way to install it?

I realize that some 74HC238 package has a slanted side to indicate the IC orientation. In this case the slanted side will go left of the PCB. Here’s the pinout – the pin 1 and 16 go towards the notch indicated in my chart.

Thanks for that ….. I did some digging before seeing your response and tracked down a data sheet for the NXP part (which I have). Once I knew about the chamfered side I found it easily enough.
Hard to notice if you don’t know it’s there though.

I will add this info to the guide.

Hi mr. Akimitsu.
Do you have a recommendation where I can buy this PIC model PIC24FV16KA304?
I bought the Aurora 48 and it´s amazing, I´d like to test more, but it difficult to find this chip with good price.
Thanks

Yeah PIC24FV (or any 16 bit PICs) are not cheap. I buy from Digikey, Mouser or Microchip Direct. Unless you buy 100′s of them the price is high.
Depending on the qty you want I might be able to give you a better price than those resellers. Email me if you are interested.

Hi Mr. Aki,
I´d like to buy about 4pcs for PIC24FV16KA304 and 4 pcs PIC24FV16KA301, but do you know if shipping cost will be expensive? I don´t care if you send me by USPS, since the packet come to Brasil,rs. Please, could you check the total cost for zip 04045-004, Brasil.
Thanks

How much soldering does this one require?
Is it easy to modify the pre-programmed looks?

I am building a project using a NFLS-RGB High Power RGB Led Flex strip inside a tube, the tube has holes along the sides for the light to project out. I am using a MCBRF-RGB4 mini controller w/RF remote to control the strip.These I purchased from
superbriteleds.com. My problem is I want to also project the lighting at the open end of the tube, it stands upright, much like a lamp. The flex strip can not be bent to the small dia. of the tube. Your Aurora 48 looks like the perfect dia. to fit this. Can it be connected to my controller so all the lighting is in sync? If not, do you have or can you make any suggestions to help me?
Thank you for your time and consideration in this matter.

The short answer is that your controller won’t be able to control Aurora 48. I think it’s possible to modify the firmware to read what the controller is sending (which is 3 PWM signals) and change color(s) accordingly…
The LED strip you are using is analog type, which is simply RGB LED with current limiting resistors attached. Very easy to add your own LEDs.

Hi, I have just purchased a kit ‘not programmed’. Where do I download the .Hex file for the programming the PIC?
Thanks

Sorry, I forgot to upload it. Now I just added the file above, and to the instructables.

Hello David,
I will email you the source file. It’s great that you are teaching your kid technology already!
