Description of Idea:
Can you someone please help make this?

MMC Entry I.D: 6318

@MMC_Jake MMC_Is there anything in the library similar to this?

Hello @MMC_Jake @MMC_Shanelle ,

Is this still in need ??
If yes, then i could make it and upload the design and circuit.

Hey @Gurbaksh_Singh - let me follow up with the original requestor as it doesn’t look like they are connected to the forum.

There is currently a project in the library that should satisfy this request: https://www.makersmakingchange.com/project/switch-modifier/. There may be an opportunity to improve that project.

Hi @MMC_Jake,

Below is my prototype for your reference, please have a look and let me know if you have any findings:

Prototype Video with 2-Way Inputs

Prototype Video for Delay Setting

Prototype GIF(try this if above videos load slowly)

This device can be made within $10-$20 with very little soldering work.

Here are few pics of the same for more details:

The relay i used for my prototype : https://www.amazon.in/xcluma-5V-30V-Module-Trigger-Adjustable/dp/B074QV7N58/ref=sr_1_14?dchild=1&keywords=timer+relay&qid=1623009581&sr=8-14

Here is the alternate link for the timer relay modules on:

Let me know if you feel this could be added to MMC’s Device Library, and then i could make a 3D Printable Enclosure and proper documentation for this device.

Thanks…!!
