FX3 LVDS Frame grabber

Sat, 04 Jan 2025 00:00:00 +0000

What is it?

The 16bit-LVDS-FX3-Framegrabber is a Cypress FX3 SuperSpeed Explorer Kit-based PCB, which can digitize a parallel 16bit digital video stream from a commercial image sensor. It exposes a USB 3.0 UVC (“webcam”) device to the operating system.

Video signal is accepted on a 50pin SCSI-II connector as parallel LVDS.
Required signals:

DATA_VALID
HSYNC
VSYNC
PIXCLK
DATA0 through DATA15

The framegrabber follows the common industry standard pinout for 16bit digital LVDS video.

A 20 port USB-C charger in use

What is it?

The 20 port USB-C charger can charge up to 20 USB-C devices from a single USB-C supply.
Each charging port can deliver up to 7.5W (5W if all ports are in use) and is individually current limited.
The charger was developed to charge a whole litter of Blinkekatzen from a single supply.

Thermal camera macro

What is it?

3D-printable adapter, which fits into commercial thermal cameras and adds a 18mm ZnSe CO2 laser lens to the optical path.
This greatly improves the imaging quality on small electronics / SMD parts.

7 small rod magnets are used to snap the lens into the camera magnetically.
The lens to be easily removed for operation at regular focus distances.

Gigaset DECT debug adapter

Fri, 23 Dec 2022 00:00:00 +0000

What is it?

Gigaset-Debug-Adapter can be used with many Gigaset DECT phone models to access the internal UART.
It’s basically a 1.8V USB->UART converter, with switchable strapping logic and 3V step-down converter.

The device fits into the battery tray and mechanically emulates 2 AAA batteries.

The dialog-cr16c-uart-boot bootloader can be used to upload a stub to the phone through the boot ROM and access the SPI NOR flash chip.
