Hello I'm Jesse and I'm solving problems no one else seems to be having.
GameBoys, programming, electronics, whatever I can think of!

Hello I'm Jesse!
I make youtube videos mostly about GameBoys www.youtube.com/@systemoflev...
Some of the videos are deep dives into how the GameBoy works; like my recent series on memory www.youtube.com/playlist?lis... or my ongoin series on graphics www.youtube.com/playlist?lis...

Well I got the right chip up but I managed to rip off a pad AND lose a tiny resistor. So much for my cheap fix for my old camera
it took a lot of patience but after a while I finally managed to get half of the wrong chip desoldered and up... good thing I doubled checked before getting all the way desoldered
the right chip looked easier but it's in way tighter quarters. My chunky soldering tip might not be up to the task

You should learn to program in #GameBoy assembly! Do it!

The fusion page in DaVinci Resolve is dangerous. You can do so much that I just spend all my time figuring out how to do every silly idea I have
This is a node that masks the input to only show the area in the window and it lets you resize the window without scaling

it's really annoying when a product is marked as "less sugar" or something and it turns out the just replaced the sugar with a non-sugar sweetener
I don't want the flavour of those sweeteners I just want less sugar. I'm ok with it being less sweet

My grocery store hasn't had sliced dill sandwich pickles for a while, only sweet ones. So here I am slicing my own pickles like some kind of prehistoric nomad

I spent way too long making something to let me get video that looks like it's looking up through my keyboard.
I also made it smaller than life sized by accident. Oh well, seems to work well enough!

I made this bracket so that it's marginally easier to mount and unmount my camera and I'm only slightly very afraid it will fall apart dropping my camera to the floor

oh my god this script is getting so long. I don't know why I thought it would be quick to explain.
Maybe I'll record it in two sittings to avoid being completely monotone by the end

I tend to forget what endian the game boy is and also what the two endians even mean. So today I googled to see if the game boy is big endian (it's not, it's little endian) and I was met with my own video as a reference! That's neat! Could very well be a personalized result, but still neat!

I went for a short bit picture taking this morning to maybe get some creative juices going. Here are some snaps

Well we didn't end up using this. The kids were entertained enough without additional activities
I made a pin-the-tail on the comet for my kid's birthday party with a bunch of sticker tails. It turned out good enough!
The transparent vinyl for the comet didn't work out and I had to add an opaque backing. Lesson learned.
I think the starry background I made with my kids is the best part

The final installment of my "make a Game Boy emulator" series is out! I cover audio, memory, and timing this time youtu.be/Be5v8E21pEQ
Despite me claiming I don't understand #GameBoy audio, making this video ended up tricking me into starting learning about it!

I happened on one of those lego game boys in the store today. I'm conflicted about them. On one hand they're cool. On the other hand I don't need more ~~things~~ (I have many things as it is).
I opted to not get it. We'll see what the future brings though

I'm new to the apple macintosh operating systems, is there no way to switch between windows from 2 apps without getting all the windows from the app? Like if I want to drag files from finder into an app, can I not just get that one finder window I had last instead of all of them
I just want alt+tab

Ok, more #webaudio playing. I made a step wave in two different ways:
by adding square waves that only supports powers of 2 for the number of steps: www.systemoflevers.com/misc/audio_v...
by adding pulse waves that supports any number of steps: www.systemoflevers.com/misc/audio_v...

I don't know what I'm doing
I made a pulse wave with basic #webaudio nodes from a square wave: www.systemoflevers.com/misc/audio_v...
Then I looked it up and it's super simple with sawtooth waves: www.systemoflevers.com/misc/audio_v...

Well I may have nerd sniped myself into learning about the web audio API and Game Boy audio. Two subjects I've spent years intentionally ignoring
I want to go play around more but I'm too tired to brain good so it's off to dreamland
