Floris I'd like to build a pepper rev2. Would it make sense to update the Rev 2 Mouser BOM? As some parts are unavailable at the moment. Also, it seems I can't erase the unavailable (backordered) components out of my Mouser cart. Any advice on this?
giuliomoro Floris , it seems I can't erase the unavailable (backordered) components out of my Mouser cart. can you set the qty to 0 ? Floris Would it make sense to update the Rev 2 Mouser BOM? As some parts are unavailable at the moment. most parts are generic and you should be able to figure out a replacement for caps and resistors without much trouble. @bela_robert had a list of possible alternative ICs, I believe?
giuliomoro @Floris btw, thonk should have full kits available https://www.thonk.co.uk/shop/bela-pepper-kit/
bela_robert giuliomoro Thonk currently have 2 full DIY kits left in stock but not ideal for EU customers.
bela_robert Hi Floris, yes we saw the NE533AP is out of stock, the semiconductor crisis is hitting in the most unexpected places! As an alternative you can you the LM833 https://www.mouser.it/ProductDetail/Texas-Instruments/LM833N-NOPB?qs=QbsRYf82W3H%252BAalsg64rWQ%3D%3D or OPA2134 https://www.mouser.it/ProductDetail/Texas-Instruments/OPA2134PA?qs=7nS3%252BbEUL6uyT34OzaiM4g%3D%3D
Floris thanks! one more thing: would there be a more colourful alternative for the 10 Segment Red LED Bar? It's a great feature, but often I find myself counting for which led I have to read.
giuliomoro I don't know of multi-color LED bars, but maybe you could just place individual LEDs in there, so you can mix and match colors to taste.
bela_robert giuliomoro something like this could also work: https://www.diymore.cc/products/10pcs-10-segment-colorful-led-bar-graph-indicator-dip-blue-green-yellow-red I like the idea of individual LEDS with a custom housing of some sort. Note that if you are changing the colours of the LEDs you may want to adjust the accompanying resistor values slightly to get the optimal brightness. R26-R35 (220).
