I did a tonne of minor case work for the device and got it all buttoned up and added a power LED.
.
I also filmed and edited a video advertising and showing off the maraca cracker 2000 with my friend and totally did not rip off dankpods in the process by blowing up earbuds and overdriving speakers that I couldn’t lapse BECAUSE LAPSE DOESN’T WORK ON LINUX (please fix this nothing works about it I have brought this up multiple times in stardance-help in slack and I’ve gotten nothing)
.
NEXT: I need to pull all the documentation (that I still need to make) and files into a gitlab repo
After more case work we have a top for it and the best branding known to humankind MARACA CRACKER 2,000!!!!!!!
I’m really happy to see this project come together as well as it has
I did a majour boo-boo where I moddeled the case as if the amp was 15mm wider
and on the remodel I mucked up the case’s screw holes that I now realise I really need two more of. will do more soon
More case work with fusion, not terribly interesting but it must be done :( The volume knob now fits and the audio input is screwed into the case as well. I’m contemplating the design for the final case too. I must first do the basic case then make it look nice once that is done I can add cool patterns, text and MARACA CRACKER 2,000!!!!! MUST MAKE DADDY DANKPODS PROUD (lol) I’ll blow up some dirtybuds in the demo video too! (or at least try)
I recently locked in and did a tonne (kinda forgot to post a bit) But I started designing a case in fusion 360 (FreeCad stinks) I also put screw terminals on the side with a DC barrel jack for power input (edit I put a picture in as I realized I completely forgot to add one LOL :3)
I’ve kept myself busy! I’ve soldered in the socket and part of the right channel, the rest of the circuit’s parts have been pushed in and I will solder them in the morning. additionally I have soldered up left / right RCA jacks and a volume knob out of two trimpots vertically mounted and attached with a board at the top.
This is all going surprisingly well considering the complexity of building a dual-channel amplifier with just the datasheet’s schematic to go off of!
My goal for this project is to build a small high power amplifier that also doesn’t look trash and start fires. BUT STILL PLAYS SCARLET FIRE
I just dropped $50 NZD at jaycar for parts for this project 💀
somehow I managed to perfectly assemble one channel just out of following the datasheet’s example schematic, I know I’m amazed too but miracles happen! attached is the schematic I was using and a picture of what I built
