I'm looking for a custom lightguide to use for a white LED segmented LCD backlight.
The thickness of the lightguide has to be around 0.4mm.
Could you give me some name of society which could do this (like GLT for example)?
Best regards
Hi, I'm looking for building a custom protection circuit for rechargeable lithium ion polymer batteries.
The three protection offered by the standard PCM are :
- overcharge voltage
- over discharge current
- cut-off voltage
Assuming, the charge voltage is regulated and controlled by the...
Hi everyone, I have a simple question;)
It is possible to measure the ESR of a 32kHz quartz with a LCR meter (for example the LCR 8101) but while the quartz is already soldered to PCB and connected to microcontroller. The circuit is powered-off.

Hi, everyone,
I've tried to search for an already written post, but without any success.
I'm looking to study the problem of "feedback voltage" from a piezo diaphragm after a shock, but don't really understand how to make that. I want to drive the buzzer in differential mode +/-9 V with a...
