  Design the Simplest DC UPS with super capacitor for home router and raspberry pi
Posted by: RustyOx - 28-03-2023, 06:21 PM - Forum: Rusty Ox - No Replies

Schematic

[title_image]

In:12V
Out 1: 12V for home router 
Out  2: 5V 3A dc/dc module
Out 2: any voltage 
C1: 16V 83(500/6)F
R1: 100 Ohm 2W or 330 Ohm 1W
D1: 3a schottky diode
Discharge chart: todo

  • Dc/dc module: 
widely available from amazon or eBay 
Search  adjustable  buck dc dc Converter, example picture below. 
   
  • Super capacitor example:
   
  • Capacitor energy calculation:
Assume discharge  from 12v to 6.5v, voltage  drop is 5.5v.

   
From: http://www.learningaboutelectronics.com/...ulator.php
  • Run time calculation
Assume  Raspberry Pi is consuming  0.5A at 5V, which is 2.5W.
The run time for Raspberry  Pi is 502s which is about 8 minutes. 


   
Ref: https://www.omnicalculator.com/physics/work-and-power

This UPS is maintenance free (normal UPS needs battery which will be replaced regularly).
  • The cost of component:
DC/DC: £2
D1 and R1: £1
Supercapacitor 83F 16V: about  £35

  Add ZigBee energy meter in consumer unit

The current transformer CT size is 10mm 1000:1, the hole is too small to fit in main input cable, so I add it to the sockets input.

  Zigbee Smart Mains Extension SM-SO306-K with Zigbee2MQTT Issue (Fixed)
Posted by: RustyOx - 09-12-2022, 11:38 AM - Forum: Rusty Ox - No Replies

Not works on old Zigbee2MQTT version such as 1.24.0, tested works on Zigbee2MQTT 1.28.4.

Due to a bug in Zigbee2MQTT, all the 5 sockets (inc. USB) turn on/off together, also ZigBee interview is not successfully. See https://github.com/Koenkk/zigbee2mqtt/issues/12442.

Note: After upgrade Zigbee2Mqtt, you may need to remove the device and add it again.

Brand: Jonvoo / UseeLink
model: SM-SO306-K (recognized as SM-0306E-2W by Zigbee2MQTT)


Also known as: ZigBee Extension Lead Smart Power Strip USB Surge Protector Smart Plug Voice Control Compatible with Alexa Google Assistant, Remote Control,APP Individual Control ,Timing Schedule Overload Protection

link: https://www.zigbee2mqtt.io/devices/SM-03...m-0306e-2w

Issues: the USB output is not properly designed, it causes RCD tripped in my use case. The viewsonic projector is connected to first socket and connected to a Google TV. As long as the Google TV USB power cable connected to the USB power port, it trips the RCD. This indicates the USB power is not properly designed, it is likely provide the current leakage path between earth to Neutral/Line and tripped the RCD protector. There is a small chance something wrong with my Viewsonic X10-4K projector or Google TV design, and caused the RCD tripped. The real reason is unclear to me.

  MR16 12V LED light flickering Issue Caused by Transformer Thermal Cut off
Posted by: RustyOx - 17-10-2022, 01:47 PM - Forum: Rusty Ox - No Replies

It is caused by the thermal cut out of the transformer.

The transformer is running warmmer than the others.
