My eket pbx server.
Trying to tidy my pbx for my collection of vintage telephones need to figure out a pdu to power everything. I have a 12.5a power brick but worried it will not be powerful enough

Current project for cable management and converting
Mk1 of all telephone pcbs I'm trialing for my pbx.
top takes 4 rj11/12 and puts it onto one Rj45 so I don't need to make 4 long rj11 cables.
The bottom left cab then take that Rj45 and convert it back to rj11 but it also has a pass through Rj45 so you can run from the pbx to each phone location. It has jumpers to select which ring tip pair you are connecting too or the top board.
The third board is my first attempt to build a ring capacitor for British phones normally found inside the master socket. It needs tweeking as the hole size is too small and I want to change the header to punch in cable connectors. Although I need to edit the design my idea is that it would drop into the gpo 706 range and equivelant phones so they can be hooked into an Ata.

Creating a 4x rj11 to Rj45 trunk
To keep cabling tidy I want to create a number of pcbs that will combine the rj11 ports on my grandsteam ht814 and 818 into one Rj45 port for better cable management around my house. My idea is that I can then have a number of break out pcbs that I can mount along the route of the cable where I want to mount my phones.
As most phone rj11 cables only use 2 cables for ring and tip my thought was the 4 pairs in the cat5/6 cable could become a mini 4 phone trunk. On each breakout board I would also put in a ring transformer for my bt phones so I don't have to use a rj11 to bt with ring transformer adapter as it would all be built in to the pcb. I am wondering if these Ata's use a common ring/tip which would allow me to increase the capacity to 7 phones or if it is better to just stick with keeping each pair as their own separate entity

Carson reflex 3 possible dammage
Hello all. I managed to plug up something incorrectly on my car and now when I power on my esc it won't complete calibration at all unless I plug it into one of the other channels on the receiver. I have plugged a spare servo into it and that works but the esc does not like it at all. Is the esc bricked completely for cars or is there something I'm not doing right with my settings. I have already done a factory reset on the controller to get rid of all my settings so I'm wondering if I have to buy a new receiver is I want to use it on my car

Other uses for duel screen on armour 33 pro
So got a 33 pro and I'm wondering what else you can use the second screen for apart from just mirroring the main screen.

Troubleshooting a freeplay s360 not playing due to battery leak
I recently bought a freeplay s360 but it arrived doa upon further inspection it seams that the ni-mh batter had leaked and wicked down the wires to the back of the board. I have started cleaning and assessing what can be done to revive it but looking for some pointers.
I am aware that the spring mechanism is dangerous so have taken precautions while working with it ( I have and have repaired several of the larger models over the years,
Will upload pictures when I'm back at my work desk
