pi based systems

[wl1]

Hi

My RPi official touch screen display has always worked perfectly (until I broke it yesterday that is)

It should work properly by default using piCorePlayer once Jivelite is loaded.

I have been using it on my development pCP RPi for years, so I have installed pCP and Jivelite hundreds of times.

What skin are you using? I use Grid 800x600.

regards
Greg

I am using the Grud Skin 800 x 480. There doesn’t appear to be a 600?

Is this correct?

That's the one. As mentioned, I broke my screen and was using my memory which seems to be also broken....

My old Denon DRA-565 receiver died almost two years ago. After buying a new amp I was questioning what to do with the old Denon. Inspired by the examples on this forum I decided to go for a Raspberry Pi based player built into the old Denon case and using the Denon VFD to display titles, menu etc. It ended up with lots of trials, software and hardware. I spent a lot of hours reading, learning and building and I finally got to the point yesterday where I closed the case. It's not finished completely because there is still some work on the remote IR control and I want to design a PCB for the VFD driver. But it's functional with the old volume control replaced by a rotary encoder and some old buttons connected to the GPIO.

• Hardware:
  
  • Raspberry Pi 2 Model B,
  • Hifiberry AMP,
  • AMB σ11 regulated power supply (12VDC),
  • VFD driver (own design)
• Software:
  
  • piCorePlayer 3.5.0
  • Slimmer
  • LCDProc
  • Pikeyd
  • A custom Python script for serial communication to the VFD driver

Here are some pictures of the result:

Brilliant. Love it.

Really too cool. Great re-use of old technology! Congrats.

Lot of ideas can be use thanks for it! Though this is not easy but I'll read more and try to make my own pi system like those

[Pascal Hibon]

This is version 2 of my player. I decided I did not like the two-chassis approach and put everything into one Hammond box. In order to do this, I had to design a small PCB and get it fabricated. The PCB contains the rectifiers, filter caps and linear regulator for the +5 volt supply for the Pi. It also contains a battery charging circuit for the LiPos and a set of relays which switch the batteries between parallel (charging mode) and series (playing mode).

I use a GPIO pin from the Pi to control the relay circuit. This is set up in the piCorePlayer web interface and works in conjunction with the LMS PowerSave plugin, as suggested by Pascal (once again, thanks!). When the player is idle, the batteries are put into charge mode when LMS PowerSave times out (minimum of 15 minutes).

While playing, the batteries are completely "floating" and power the Allo isolator which sits between the Pi and the Allo Boss DAC. Thus, the DAC is galvanically isolated from the Pi and its noisy digital circuitry.

The custom PCB is the small board in the middle. You can see the TO-220 type regulator and a couple of the Schottky rectifiers bolted down to the chassis for heatsinking. The batteries are on top of the Raspberry Pi display controller board, which is flopped down to a horizontal mounting position.

Still to do - possibly add some shielding around the toroid and the output RCAs (but it is very quiet electrically). I would need some instrumentation to measure any improvements.

That is a great build WTNH !!

My Allo Katana build retro fit into a Sugden case, with two linear PSU.
