Hi, my name is Jens, and I create beginner-friendly electronics tutorials and projects. Everybody can learn electronics! (he/him)

What happens when you combine a PIC microcontroller with the idea of retro Christmas lights? Find out in my new tutorial, happy holidays! https://t.co/MlnccBKXXV

@RueNahcMohr It's a tutorial, Rue, so I focus on one thing at a time ;-) But Charlieplexing is on the list for a future one, promise!

[FriendlyWire @FriendlyWire]

New video in the works... Any guesses what it's about? :)

[FriendlyWire @FriendlyWire]

@minusYCore @Scott_Holmes I'm trying to make a tutorial for beginners, so either it works out of the box, or it won't go into the tutorial because it's too finicky... I'll test with the new batch.

[FriendlyWire @FriendlyWire]

What's the typical on resistance of a breadboard-compatible pushbutton? Mine are around 30 ohms which I find a bit excessive.

[FriendlyWire @FriendlyWire]

@minusYCore @Scott_Holmes I have ordered a second batch to see if maybe I got some lemons...

[FriendlyWire @FriendlyWire]

@minusYCore @Scott_Holmes No capacitor, it's a resistive ladder

[FriendlyWire @FriendlyWire]

@minusYCore @Scott_Holmes These switches are just bridging resistors in a binary-weighed resistor ladder. Current is around 3mA. Unfortunately the parasitic resistance makes them unusable, up to 5 ohms would have worked, but this spoils the accuracy.

[FriendlyWire @FriendlyWire]

@Scott_Holmes Yeah it sounded a bit high to me, too, but I compared with other pushbuttons, same setup (alligator clips and my GW Instek GDM-8245), and they read much lower in the regime you mentioned. Bad batch?

[FriendlyWire @FriendlyWire]

@ChuckHellebuyck This is outside the breadboard I'm afraid...

[FriendlyWire @FriendlyWire]

@RueNahcMohr It's been a bit more quiet than I'd like because I am quite busy at work these days. But we're working on 2 new videos :) Thanks for checking in, Rue!

[FriendlyWire @FriendlyWire]

Any tips for photographing LCDs?

[FriendlyWire @FriendlyWire]

@paulgeraghty OK, hint: this has a 30cm diameter :)

[FriendlyWire @FriendlyWire]

Anybody know what this is?

[FriendlyWire @FriendlyWire]

Now what could you build with this... :) Tutorial coming soon!

[FriendlyWire @FriendlyWire]

Sneak peek for the upcoming video... Any guesses?

[FriendlyWire @FriendlyWire]

@matseng @Hacksterio Yeah it's really more of a general purpose idea :)

[FriendlyWire @FriendlyWire]

@3DPrintAficio This will be a one-off project, so no PCB, just hand-wiring on a perfboard. But I want to make it easy to understand for beginners (on my channel I have covered all components, with the exception of the LCD, which will come in the new year).

[FriendlyWire @FriendlyWire]

A bit more parts on the next project... Any ideas how to make the schematic more readable?
