BOM and sourcing components
Firstly, I love this project. Not just from it's sole purpose, but also for someone trying to learn electronic engineering better. I am studying the PCB to try to figure out how everything was done and the purpose of each yet.
I figured I'd start to build at least one of these. I created a BOM here: https://octopart.com/bom-tool/xXZMKVQA
The issues I have thus far, are:
- Making sure everything on that BOM is correct.
- Sourcing specific components that seem to be obsolete or not readily available.
Can you check that this BOM is correct, or supply one separately, to address issue 1?
For 2, I'm finding that SFH4346 is considered "obsolete" and not readily available anywhere that I can find. I think that SFH4546 might be a replacement, but I'm unsure. Additionally, trying to source the CH340C is tough as far as I can tell outside of LCSC. Is that where you got yours, or did you find it (or an alternative) elsewhere?
Thanks!
Just a heads up, the MIKROE-1120 is US Only from Mouser and DigiKey. Anyone outside the US might have to source a comparable battery.
That's definitely a good note. I didn't specifically look for availability per country, but it's likely wise. I imagine there's a similar battery for other countries, but we may have to search for it some more.
Hi @mandreko , I've added a BOM to the project now: https://github.com/CoretechR/OMOTE/blob/main/PCB/BOM.csv These are the parts that I ordered when I built the remote. Maybe you can check that against your list. The IR LED should not be an issue. You can probably use any 3mm IR LED.
If anyone in Europe is looking to sell an assembled one, I'm interested.
For those trying to source the CH340C, I just ordered some from this aliexpress vendor. Fingers crossed they're legit and work, but it was only $8 total, so it's worth a shot.
If anyone would sell assembled PCB's i would be interested. 3D Printing is not a problem. Love the Idea of an remote you could also use for MQTT!
Did R1,R38,R39,R40 get removed? I don't see them in the BOM.csv file.
@moserja Good that you noticed, R37 was missing as well. Should be fixed now.
Is there any way to subscribe to see when somebody decided to sell a ready made pcb (in the EU)? I'd love to have one of those, but my attempts at smt soldering have been very fruitless so far.
@dekiesel If something comes up, I will definitely post it on Hackaday.io and Twitter.
I'd also be very interested in buying an assembled PCB.. had a look on tindie.com, but nothing yet :)
@JediMongoose Give it a couple weeks, and there likely will. I’ll be at least buying components for enough boards to put up there in small quantities. (US based)

I ended up here due to the hackaday feature (https://hackaday.com/2023/07/15/hackaday-prize-2023-omote-universal-remote/) - I'm sure there'll be more :smile:
I'm doing a struggle to see if I can get PCB's made and see how impossible this is to solder myself. I've never done more than through-hole so this should be interesting. I have an immediate need for at least 2 of these, ideally expanding them with a hub when that is finalized. Also would love to help in any way! My life is a void now that Logi dropped Harmony.
If it’s helpful, I’ve purchased the PCBs and components for about 10x remotes. Once they come in, I’m more than happy to build some for others. I enjoy soldering.
I will also have a few boards that I will have left over, but they will not have the screen or battery installed. Those are easy additions though.
I will have 4 pcbs left over from the batch I ordered.if someone wants one and is willing to buy the components I can solder them.
I'm from the US

I'm also in the US. what would be the best way to contact you?

I'm interested in buying a populated PCB, and willing to pay in advance if required. I live in Sydney, Australia if you're willing to post to Aus
It would be helpful if the people that are offering to help others would say where they are located.
I'm also in Australia if anyone is selling partially or fully assembled PCBs.
Or if anyone has uploaded it to PCBWAY or another service?

Hey! I'm located in the US and am happy to buy a pcb in whatever state it is currently in so no additional work for you. I'm happy to source and populate whatever components aren't already there.
Thanks so much! Feel free to dm me!
Amazing project by the way!!!
Anyone has already ordered the PCB from JLCPCB? Are there any special settings to be made, or just trhowing in the gerber.zip for PCB and Stencil and you are done?
I ordered them from jlcpcb, I should get them today. I will let you know how it goes. I didn't add any special settings, and got the stencil as well as the pcbs.

I did nothing special. I just have them the gerber file and they look perfect. I’ll be soldering them once my last component arrives soon.
Looks good. Are there any services where you can order the other parts supplying them the BOM or did you order every parts seperately? Maybe letting JLCPCB solder at least one side would also be an idea.
I ordered from Newark, Mouser, Digikey, Adafruit, and one part from AliExpress (the one I’m waiting for). I used octopart to identify the cheapest part locations. I used this BOM that I made from the official BOM: https://octopart.com/bom-tool/xXZMKVQA
Single sided soldering at JLCPCB could be pretty good guidance for most since it allows for many of the small components to be added and only requiring the buttons to be soldered on later. Although I noticed when I entered my parts into JLCPCB that many of the parts didn't have the correct orientation or placement, so you need to be very careful before ordering.
