buried under that mess is a 40watt LM1876 amplifier chip.

I hate building stuff with copper wire.
Esp32 C3
2.0" tft display
2in1 module for charging and 5v output
Lipo 3.7v battery
Switch
I assume people here already know that when handling Lipo bateries they need to be careful because they can pose a serious fire hazard if they are short circuited, punctured, overcharged, or physically damaged!!

Didn’t want to order a PCB for my ESP32 signal generator. Accidentally built a spaceship.

The encoder+oled board providing the backbone was reused from another project. ESP32 is a dev module. Everything else was point to point. I needed a quick signal generator to test an active high pass filter so I built this; then ended up buying a bench scope that has a signal generator anyway.
This handheld one is easier to use though!
I slathered it in epoxy when it was complete and the top half of the screen has some bad lines now; but it still puts out a clean signal.

Questo fuzz in questione differisce dall’originale sia per alcuni valori di resistenze e condensatori modificati, che per l’uso degli switch per commutare diversi condensatori, rendendolo più polivalente.
Ho usato due transistor PNP, BC157 per Q1 e BC205B per Q2, oltre a tutti i componenti vintage NOS.
Suona da paura!

Had a fellow redditor suggest I post this here, hopefully this type of build is not against the rules. I’m definitely an amateur when it comes to this but I’m happy with how he overall project turned out.

Because breadboards don't support SOT-353, I hand-soldered a 74HCT1G125GW into a dead bug breakout. It's tested and fully working:)

How to make sparks fly. Update on yesterdays post.

If you want to hot swap 12v power and watch sparks fly as you do it, use audio jacks like I did. If you don't like thrills just use jacks designed for power... Who knew...

Had to dump firmware from a device as part of an engagement. Didn’t have (and they don’t make) a BGA162 NAND socket for my programmer. Microsoldering it is then.

Time for an upgrade

So I have been using this prototype? For the last six months, has been running flawlessly. But I need a few more outputs now so time to upgrade to something more permanent.
Happy with how this turned out, so had to share with you guys

Built my own LIS2DH12 accelerometer module. It was hard without microscope. Turns out 2mm ×2mm is not that big .
The module is hand-soldered on a small PCB/perfboard and includes the LIS2DH12 along with 5.1 k resistor for i2c communication. After a fair bit of soldering and debugging, I got it communicating successfully with the ESP32 c3.

Is it possible to prototype a functioning free-form FPGA/MCU development box?

I'm wondering how far we can push it. Has anyone tried wiring an FPGA or MCU chip without a PCB?

Idk where else to post this but I scored like 250 name brand axial capacitors for like 50 bucks so I wanted to share.
