Custom PCBs & Wearables

Falling down the hardware rabbit hole — from first solder joints and OSH Park purple boards to custom SMD designs and an NRF52 LED baseball cap.

I’ve stumbled down the rabbit hole of hardware - Arduinos, sensors, PCBs. I have no idea what I’m doing, but just want to do it all day.
Like, I can’t stop ordering packages of breadboards and resistors and wifi chips on breakout boards and jesus someone stop me.

I just soldered electronics for the first time! Why was that so fun??

First time soldering electronics

New lessons in soldering. This shit is tedious & make sure things aren’t cooked AF.

I’ve been cargo culting my way through the EE part of microcontroller fun. Thinking of designing a small PCB. I’m sure it will be fine.
I have a VERY simple PCB just about ready to send to OSH Park. First time & I don’t really know what I’m doing. Should be interesting.
My first order from OSH Park just shipped, and I can’t remember the last time I was filled with such nerdy excitement!

I ordered a bunch of single component breakouts from OSH Park because - why not?

OSH Park purple PCB breakout boards

I’ve been spending so much time in Eagle and Fusion lately, I almost dare to say I’m becoming proficient. Linking board designs to models is AWESOME.
Working on my first SMD board right now.
Last night I designed and assembled my first PCB using all surface mount components, and I feel like a whole new world of possibilities has emerged!
I legit need to make one of these. Every time I solder something up I think to myself “yep, definitely getting cancer right now”
OSH Park cost and turn around are so great, I find myself skipping protoboards most of the time. More fun to spend an evening designing a custom board than bending a bunch of error prone wiring.
I too have used Eagle and OSH Park for custom hardware! Mind you, none of mine ever turned into full fledged consumer products available for the masses.

Well, that was incredibly convenient. A couple of very minor adjustments, and was able to get the Adafruit Bluefruit iOS app running under Catalyst.

Following OSH Park is such a great way to see people’s awesome custom PCBs.
A friend was asking about LED density choices for a wearable build
I went with less dense neopixel strips because I was paranoid about battery life. I’m using the NRF52 with BLE, so adding to consumption a bit.
Someone asked about the custom light-up ears in a photo
It’s a custom set of light up ears I built - driven by an Adafruit NRF52 feather.
As someone who likes to dabble in electronics, and a custom PCB here and there - let me just say, in proper Wayne’s World style, I’m not worthy. Unreal. Gorgeous. Amazing. Top notch.
"NGL, this is kind of addictive (I bought two of the synth kits)." — @zahnster
I kinda love hand soldering a bunch of through hole stuff. It’s oddly rewarding.
"I'm new at this stuff but renewing interest because of all the Arduino stuff out there now." — @nateritter

I love this stuff! Definitely started with messing around with Arduino. Have since gotten into designing my own PCBs and sourcing parts on DigiKey. I’m no expert, but it’s more approachable than it seems.

If the jack can’t be tightened, then you have options, and the right one is kinda up to you. If you can find one with a similar size/footprint, you can de-solder and replace. Worst case, I can make you a new PCB, or you can dive in and learn Eagle!
I’m very much not an EE, and every one of my PCB orders is effectively a prototype.
"NeoPixel LED Mickey Ears — we made them flash like fireworks when you shake your head." — @adafruit

I did something similar a while back, but 3D printed so I could attach to a baseball cap. I used an nRF52 so I could control the sequences from my phone.
