The previous Pip3 was a satisfactory solution to my quest for a plug-on Lapdock Pi, but it was quite bulky. In the A+ I have found my holy grail.
Here are some pictures of the result:
A general view of the Pip4 on the cradle. Note the glow of the power LED.
A left side view showing the reset button and on/off switch.
A right side view.
The lid is easy to remove and everything fits without squeezing.
I run RISC OS.
- The case is a cheap aluminium case for a USB 2 1/2 inch drive. It is simple to file the necessary openings.
- The HDMI connection is the flexible inside of a 180 degree adaptor to the usual micro adaptor with outside plastic cut off.
- The micro-USB connector is a widely available breakout board.
- The Pi is stuck to base with small double-sided sticky pads. I used No-More-Nails removable. The position is such that the micro-SD card just aligns with the edge of the case and can be remoed with a thumbnail.
- The super-capacitors at the right are to supply current when the Lapdock lid is closed and momentarily switches off.
- The circuit board on top on the right is a real-time clock from CJEMicro's.
- The GPIO pins have been removed and a right-angle header for the RTC replaced.
- There is an on/off switch and a reset button on the left that use existing openings slightly enlarged..
