‘Trading Card Dispenser’ control box - servo switch controlled [Part 2]

Back in 2022, I posted up about the electronics

for the TCD Control Box.

This was supposed to be THE new RC switch controlled unit, see picture.

Wrong RC switch [not a momentary one]

.....rather than the previous (and very successful it was too) remote controlled version picture here below.

original remote controlled fob version

The new RC switch that I thought was the correct one, wasn't a momentary version, but an on/off one.

Momentary RC switch

So I had to get a new RC switch, from Model Radio Workshop.

The above switch then links to a (original design) micro voltage regulator (seen in next image) and an adjustable automotive timer (orange)

• The single relay controller (from model radio workshop) has been designed to allow modellers to switch one item on and off (max current 1 amp).
• The unit also allows the user to select latching or non latching mode, so in latching once switched on it stays on until you trigger it to un-latch.

These have gone up in price so had to find another (cost effective) type of adjustable timer, (The timer unit is the orange relay in below picture).

Components List for a RC Transmitter switch version:

• Momentary RC switch from/or similar link to Model Radio Workshop: MRW06 Single Relay Controller Switch
• Adjustable relay timer: example here.

Components List for a Remote control relay switch version:

• Remote control relay: example here.
• Adjustable relay timer: example here.
• Voltage regulator, 12v stepdown version: example here.

The above two versions have different 3D housings (If you'd like this), these can be found on my Prusa account page, FREE to download and print.

I have now created a Facebook page,

dedicated for the

Trading Card Dispenser.

To help and for others to share their builds and modifications etc.
