The Golden Rules of Electronics
6 days ago • 0 comments

Through the years I have identified recurring rules that underly most of my "bugs", "failures", "mishaps" and other blunders.
Rule 1 : If you connect it to the power supply, it works better.
.
Rule 2 If you connect it with the right polarity, it works even better.
.
You could argue "it goes without saying" but it goes better when you say it ;-)

Please comment and contribute with your own "golden rules" :-D

Just a friendly reminder.
Hysteresis
12/23/2020 at 01:35 • 1 comment

Playing with Fasltad's circuitjs to create a slightly better hysteresis circuit than the default circuit. It's crazy because changing any value affects the rest of the circuit.
The main difference is the feedback resistor, and a better choice of resistor values.
I tried to reduce the current draw and increase the hysteresis, which keeping convenient resistor values and decent logic levels (at least the low level is < Vbe at 3.3V).
That's if for today :-)

Things I've Built

1KW LED lighting

2006: I designed and built all the electronics of a store's architectural element. 432 3W Luxeon LEDs split in 9 sectors with independent dimming with my first HTTP-based remote controller...

Lambda

LED desk lamp concept design. 2008

Drosephyia

Working as SubFlower, Igor & I built a sort of electronic plant in 2005 for an exhibition at Biche de Bere art gallery.

😁 This place is cavernous compared to the old one. It's eaten my 10 foot cube crapmountain no trouble.

Yep. 😉 mill, forge, cast, weld, flight, windpower, resin mould, spray finsh... Tesla coil, etc... Muahahah!

Deploy. Such a great word my friend lol. Merry Techmass dude 🎅
