now granted falstad probably isn't the best sim around, but for a free one its really easy to use and intuitive. I am shopping around for good sims though so if yall have any suggestions on better sims that match falsteds simulation im open ears.

When you're prototyping but the SOIC package IC you ordered is in actuality apparently a "wide body SOIC"

Got to get creative fitting it onto a SOIC-2-DIP converter! If it works, it works!

Ayo guys this is follow up on my post 10 days ago about changing the micro usb port on third party controller so I finally got thr tp4056 and did lots of soldering and sanding t the shell of the controller but couldn't tget it to stay inside so it's gonna be external as i use it only once in a while😅

Amazing how you can have spare parts sit in draws for 25 years untouched. I'm a fan of AMD so I was excited to find two of these are from them. I'm wishing I had a better microscope to de-cap and view the die. I'll have to figure out how to see if Evil Monkeyz Designz is interested in any of these for a de-capping.

I mean atleast it didn't blow up... I really should've gotten a pcb...

I need a switch that can handle some power and don't have the patiance to wait for it from shipping, so what do we do? We take out the key ignition with bonus volt meter that's ment for escooter to be able to start it and shut it off with a key.

Recapping an Apple IIe and the size difference blew me away.

Figured someone might enjoy this 🤷🏻‍♀️

My dad built this into a Snap-On tool case back in the 80s. I'm currently working on a PCB design so he can put together a new one.

FCC ID: 2AN9S-TPX00227

Arduino’s upcoming Nesso N1 has appeared in a recent FCC filing, offering one of the most detailed looks at the device so far. Although the board has been announced, it has not yet reached retail, and the filing confirms that development is nearing completion. The documents include complete schematics, which is uncommon and provides an unusually transparent view of the design.

The Nesso N1 is based on an ESP32 C6 controller with support for Wi Fi, Bluetooth Low Energy, and LoRa at 915 MHz. It includes a 1.14 inch color touchscreen, detachable antennas, a BMI270 motion sensor, Grove and Qwiic expansion ports, and a built in 200 mAh battery for portable use. Internal and external photos show a compact layout focused on prototyping flexibility.

Tonight I've sawn a to220 insulated mosfet, so It can fit where i want

This is a stereo audio amplifier for my car, and that MOSFET will turn switch the whole module on with the electric antenna signal

Found out that the FCC basically lets you peek inside almost any device that emits RF energy. looked into a few cool products, then spent a bit too much time combing through filings that ended up becoming a huge photo set. Here are a few examples!

Holy cow, it's huge, it covers everything! These are just a few random pages. I already learned a lot.

My god.

Thought you might like this little circuit that drives an usual neon bulb. Difference from usual bulbs you salvage lies in the fact that the bulb must not have a resistor attached. I removed mine from the neon bulb fuse-like package. For anyone wondering, I found this in an old probing screwdriver that broke.

Transistor + phone charger transformer + a resistor. Take time to measure the coils. My multimeter isn't precise at all but I measured the coils to be 0.6, 1.2 and 6.7R. Once I measure it better, I will post the results but all three that I built have approximately the same ratios between them.

I am providing a bare schematic, the rest of the components on the boeard are a tactile switch, li-po charger and a battery connector.

Interesting thing is that the voltage accross the bulb is polarized and only one side of the bulb lights up (negative I believe).

I love the circuit and the vibe and I hope I'm not the only one.

EDIT: Didn't realize that I uploaded a photo instead of GIF 🤦🏻
