Hi all,

Because of the increasing cost of electricity, I've looked into running UFO Capture on a low power mini-PC. There's lots of these on the market and I recently bought a BMAX B1 for £100. It met my requirements:

BMAX B1 spec:
1.6 GHz (2.4 GHz) CPU - 2 cores and threads
4 GB RAM
64 GB storage (eMMC) - can be upgraded with an SSD
Windows 10 Home Edition
4 USB ports (2 x USB2, 2 x USB3)
LAN and WiFi
HDMI, RJ45 and VGA ports
microSD card slot
8 W power usage

All contained in a plastic box 120 mm x 120 mm x 32 mm, weighing 240 g.

It took a couple of hours or so to download and install the latest Windows updates, then it was straightforward to transfer UFO Capture from Leeds_N, a Dell PC. The video camera is connected via a USB video grabber.

UFO Capture on the mini-PC runs at ~33% CPU utilisation, with other processes taking this to <40%. I will test if it can support two UFO Capture processes driving two video grabbers.

A great advantage of such a mini-PC is the low power consumption. This model draws only 8 W and has an internal fan. The little box stays cool.

Power usage comparison:
Dell tower PC 100 W

Mini-PC 8 W


My UFO Capture sessions auto-shutdown at dawn; I start them manually at dusk.

Assuming each session runs for an average of 12 hours per day (6 hours in summer, 18 hours in winter) for 350 days a year = 4,200 hours per year

If electricity tariff is £0.33 per kWh

Dell uses 420 kWh = £140 per year

Mini-PC uses 34 kWh = £11 per year



In my case, switching from a desktop / tower PC to a mini-PC should pay for itself within the first year. The savings would be even greater for someone running a Capture PC 24/7.

If this model cannot support two Capture sessions, a more powerful mini-PC might be the solution and still be cost effective.

Just a suggestion in these challenging times.

Alex.
