Jlc and I are sort of confused about polarization of D2 diode on 4.5 module. PCB had markings K and + on the same site. According to schematics Cathode should be on the right site connecting directly …

Přemýšlel jsem, jak na detektoru implementovat self-test. Není to jednoduché z toho důvodu, že radiační prostředí se mění podle umístění detektoru. Společně s tím se mění i měřené hodnoty, což je ost…

Hi,
I can't communicate with my Arduino (Duemilanove, ATmega168) with
Firmata under Linux (Arch Linux 64 bit).
I tested both "stock" Firmata that comes with Arduino IDE and
Firmata-2.1beta7.zip d…

# Polarity / orientation matters
- the parts will be put on the side where the print is, first the small parts, then larger ones
- soldering happens on the other side (except the SMD transistor)

When the serial port is closed, the DTR pin goes from low to high. But since the capacitor in the reset line is already charged by this point, the voltage on the RESET pin becomes 2xVcc (DTR + capacit…

Hello,
I am building an Open Spritzer for someone in my department, and I have a few minor suggestions to improve the PCB:
*I think in your design D3 should be a Schottky diode, not Zener.
*Ma…

The board labeled "Gated CPA" appears to be a sense amp for reading two columns of the core memory. The board has two threshold amps/latches that feed into what looks like an output amp. I believe t…
