Sometimes there is just no tool that will get the job done quickly and efficiently so sometimes we have to modify an existing tool or create our own to accomplish what we need in much less time then prior methods.

 

I work primarily in medical supplies as a technician for repairing things from scooters to oxygen machines and so on.  One of the things that sticks with me the most is the amount of time I spend trying to test clean and replace IR and RF remotes for devices.  Usually you have to have the device near you to test to see if it will work.  Well in covid times if someones hospital bed remote isn't working it would take us probably a half hour to get gowned up and run through all the tests to be able to see the bed.  Now if it doesn't work and you have to come back more then a few times it can be very wasteful in time.  Plus we want to get the device working for the client the first time so that way their devices they rely on for their day to day mobility needs are met without and big struggles or battles.

 

Thus the IRRF-2000 was born.

 

I wanted something that a client could drop off their remote and I would be able to have a tester to make sure all the buttons where functioning correctly and that way I would just have to drop it off at the front desk if they were in a facility or if at home limit the amount of contact I had with them.

 

So with this I started on a breadboard making my mock up of my circuit which seemed to work then when I was searching around I found a great idea about adding some 1SS86 Diodes to a circuit and it would actual pick up the RF Frequency enough to light a led.  Well I haven't tested it but I thought when I go to design my board that I would add it into my design to add an extra feature so now I would be able to test both IR and RF remotes.  This was a win win in my books.

I really enjoyed this project it taught me a lot. I tossed it in my tool kit at work and the very next day I ended up using it saving me a ton of time in diagnosis of the remote I had brought into me.

well now its on to the full video on this here:

 

 

 

There will be some more photos and small update on here soon.
