    The ProtoBoost V1

    This is still happening, just doing more rounds of testing, I apologize for the ridiculous delays on this.

    The ProtoBoost V1

    So, got everything today finally, and the boards didn't work as planned. I'm guessing it's likely because the IC I was using wasn't a "standard" chip so to speak, since it uses a gated oscillator, instead of the standard current feedback based topology. Ah, well, I redesigned it slightly...

    The ProtoBoost V1

    There is a shutdown pin on the main IC, but I don't believe it's intended for PWM or TTL, unfortunately. Maybe sometime down the line I'll put together a driver with that capability, but this all depends on how popular this particular driver is in the first place.

    The ProtoBoost V1

    Just an update, i got the boards in yesterday and ordered the parts to build them fully today. Will let you all know how it goes.

    Advice with life

    Sorry about not replying back to this! So I'm basically going to be going back to NY from the 14th to the 31st, to get an idea of what it'll be like living with my grandpa first. After that, it'll come down to how it was there, and what schools I get accepted to. Hopefully I get accepted to...

    Adjustable Test Load

    Yeah, I figured that was what the issue is. I keep wrestling with whether or not it's worth it, and I keep coming back to, no, it's really not. And the circuit diagram isn't really well labeled, but it's basically an approximation of what's inside most linear voltage regulator IC's. I thought...

    Adjustable Test Load

    So I've dabbled with adjustable test loads before, using discrete components. However due to the method of operation the actual V-drop would take some time to actually go into effect, preventing it from reproducing the actual way laser diodes function... Aka, It'd be super high resistance for a...

    The ProtoBoost V1

    So... I may or may not have a driver currently in the works. It is my understanding that there is a severe lack of readily available drivers on the market right now, and as such I'm attempting to step up to the plate to, hopefully, fill that void. Now. The ProtoBoost. This is not going to...

    Discord server for electronics

    Hey everyone; I made a discord server for everyone who's into electronics and whatnot. Here's the linkyloo https://discord.gg/3Akz2Ur Figure it might be a nice place for people to chat and talk about projects they're making. Hope to see some of you there!

    Advice with life

    I spoke to my mom more about my thoughts, and we both agreed that I should go up to NY for a few months, to live with my grandpa first to get an idea of what things would be like living with him. Thankfully she heard me out, and after telling her about the increased responsibility thing and how...

    Advice with life

    No, different one. I'm never getting back into a relationship with my ex, not after what she did to me. Schooling is going to be paid for by my parents regardless of what choice I take. My dad invested in the Texas for Tomorrow fund some amount of years ago, when we lived in North Texas, so...

    Etching copper PCB with 405 nm or 445 nm laser

    Well, so... I might be getting a 3D printer this christmas. And I can 3d print a head attachment that allows me to use a laser head, to make it into a laser engraver as well. My question, is it possible to etch away copper PCB's using the more high powered lasers, or is that really only...

    Potentially Restarting driver production

    Ah, guys, I'm sorry.... I don't know if I'll actually be able to do this now, I've just gone through literal hell with some social situations.... .... It's a very long story but... yeah I apologize. I'm trying my best to get through this shit but depression is a bitch.
