Mini Hydra - 5 inputs 1 output automatic SCART switch

DISCLAIMER:

"Be aware that in the context of retro gaming, there are two types of csync signals:  TTL and 75 Ohm.  Most displays and processors will require 75 Ohm csync, but some can accept TTL.  As a general rule, unless your setup specifically requires otherwise, your target goal is that the cables you use with your consoles will all be outputting a 75 Ohm signal and the target device will also be receiving a 75 Ohm signal."  RetroRGB 

Before you buy, be sure You have proper 75Ohm sync cables.  

Please READ FAQ for more details!

Fully automatic SCART switch with full galvanic inputs separation.

• 5 SCART inputs (RGB, s-video, composite)
• 1 SCART output
• Extra protections for NCS CHIPS on each SCART input
• Improved signal detection histerisis (all cables shall work now)
• "Knight rider" style active SCART detection
• full ROHS
• AVR controller with firmware future updates
• HQ acrylic transparent case (laser cut)
• Stereo RCA audio output 
• headphones jack amplified audio output (adjustable volume via remote)
• IR controlled
• manual/automatic mode
• DC/AC 5/2.1 mm power supply connector (suggested 9V, polarity independent); optionally you can use PWR4 dedicated power supply
• Dedicated remote will be available in the future, but you can use any NEC/ENEC compatible one - please, check FAQ for more info
• Approximate dimensions: 18.5 x 9.5 x 4.5 cm

How does it work?

Imagine, You have many retro system in use. Amiga, Atari ST, ZX spectrum, etc... And you have only one classical TV/Monitor with one SCART input. Each time, You want to switch system, You have to connect your machine to your monitor. Every time, you do it - you damage SCART socket inside. Those days are over. Connect up to 5 computers/consoles to Mini Hydra, then connect the device to your TV/Monitor and power on. Since now, Mini Hydra will detect active SCART input and forward all signals to your screen. Simple and efficient.

Please, remember:

NEVER connect / disconnect SCART plugs when Mini Hydra is on especially when console/system is on!

You may ask why...?

Device is designed to  pass through many types of signals: from composite to component. To protect device and not to cut signal's range, Hydras have additional ESD protection diodes, but for a short period of time when scanning for active SCART, Hydra is defenceless. If you hit that moment plugging powered on device, you will damage RGB chip with ESD voltage that may reach thousands of volts (not dangerous for you, but electronics is fragile...). This chip may become very hot and protection will probably brick Hydra till one of chips is replaced (NCS2564).

Possible symptoms:

• knight rider effect stops
• one SCART port does not work
• Interference between ports
• HD LED does not work anymore 

USE SIMPLEST SCART CABLES POSSIBLE 

• No tricky electronics inside as it is not needed. Hydra has built in all necessary features
• Hydra loves composite video or luma at pin 20 of SCART
• When you have fun, Hydra does plenty of work – let it work
• Hydra doesn't like and will not lock on SCART with TTL csync as it doesn’t follow SCART 75ohm standard – nevertheless if source connected directly to your TV works OK

BUTTONS:

• left - scan for active source to the left from active one (if active is far left, no action)
• right - scan for active source to the right from active one (if active is far right, no action)
• middle - HD/LOW PASS filter - default ON
• left + right pressed - disables "knight rider" LED effect
