Testing

Hey folks, there have been some issues reported. I would like to ask, that where ever this message shows up for you, if you would please reply to that location (Facebook, email, Twitter, WordPress, etc) that you received this message.

Many thanks.

Raspberry Pi power and mounting

I’ve been in need of a good way to mount my growing collection of Raspberry Pis (rpi) and to power them from a convenient power supply. Wall warts are notorious for not supplying the correct voltage or meeting the right amperage requirements. To that end, this article was begun.

A bit about my needs, I have a rpi that includes additional hardware in the form of what is called a “hat” and also a SATA hard drive. This hat fits on top of the expansion header on the rpi, and provides additional functionality. For this article, I will be using the club repeater antenna monitor system as an example.

The initial setup consisted of a rpi, a Pi-plates DAQCplate (for Analog to Digital Conversion), and a SATA to USB board for the hard drive. The system runs from a 5Vdc/4A AC/DC power supply (wall wart). During testing under load, the power supply regularly dropped to 4.8Vdc. The rpi requires a voltage between 4.8 and 5.2Vdc. Below 4.8Vdc, the whole system becomes unstable, with possible loss of data, poor A/D acquisition, and a whole host of other issues.

After a fair amount of searching, I came upon a hopefully better approach to the power supply issue, in the form of the Bitscope Blade Uno Pi (BB01). This has a few useful features beginning with a wide range (9 to 48Vdc) power supply which outputs 5Vdc at 3A (4A peak). This allows me to use any of my ham radio power supplies and/or battery systems to power everything. Additional features of the BB01 include an extra 5Vdc power header, and dual USB jacks to power other devices.

More to come soon!
