Solar Powered Mobile Dental Bus. The details. This past fall (2023) I was contacted to maybe install a solar panel to run a refrigerator in this planned mobile dental office. I asked how will the rest of equipment be operated and they were planning on running a generator. I personally have lived on generator power in the past. It gets expensive, fuel and maintenance, and noisy. I said how about enough solar and batteries to run everything? And an idea grew and evolved into quite a project. The bus originated in Spokane Valley Washington and was driven to Yuma Arizona where I knew I could get large solar panels and had more time to work on it. I had just over 2 months. Keep in mind I was still working my main job and this is busy season for me. Nearly every weekend and weeknight I spent and many volunteers worked when I was at my normal job. I did not anticipate how much time it would take. My goal was 5000 watts of 120 VAC to run all the equipment and similar in solar. In the end, we accomplished 4280 watts of solar, a 6500 watt inverter, and 10 kWh of Lithium batteries. I also took on much of the conversion of the interior. Re-arraigning/ seats, removal of unnecessary equipment, installing air compressor, mini split ac system, counter, cabinets for the electronics and air compressor, water drain tank system, lighting outlets etc. I had some great volunteers which otherwise I could not have done this. I had no worries about doing the electrical system. Mostly that went straight forward well until the last few days. What I had not anticipated was the complexity and cost of the rack we built to hold the solar panels. And as designing on the fly had a few changes / additions and cost way more than I estimated. All came together quite well at the end. However 2 days before the bus was to leave, on Saturday evening of course, I made a mistake troubleshooting, shorted a line and damaged the Inverter, the heart of the system. A wonderful friend made a 500 mile round trip drive to nearly LA and back on Monday to pick up a replacement Inverter, he arrived at 10:30 pm and by 2:30 am Tuesday it was again all up and running and ready to roll out at 9 am. It made the 2500 mile journey to Poptun Guatemala. All the panels and equipment held up well. They used electric heat and ran AC system along the trip without issues. Upon arrival it had some additional equipment installed and setup for operation. And in the first day saw around 25 patients. All services are provided free of charge to the people of the villages this bus will visit. The solar system is working great. With overcast sky’s the batteries maintained the compressor, sterilizer equipment and necessary tools for 2 dentists ending the day with nearly 50% battery power remaining. With full sun the system support the equipment and charge the batteries. It was a fun albeit a bit stressful project for me and many friends that helped me. I’m going to add many pics and try and label them. This will follow around with the organization h2oforlife.org. Which is a great organization that drills water wells for villages. Look them up of you want to get involved. Also I still have the Go Fund me active to assist with parts and labor that has been done. I want to thank these folks as I tried my best to make a list of tasks that could be done while I was at work. Something that’s difficult for me to do especially when the ideas, plans are all in my head!

Awesome 😊...the mroto startac of the 1900s

Some of these units also have built-in Telegraph keys, or contactors. That would work by pushing down on the adjustment knobs. The connections were made, with a slot that was cut into the bottom of the case. You could slip a bare wire inside of with one connection, the other one was made through a very small phenolic or porcelain insulator with a sleeve that you could put a wire into. Usually there was a set of wires with jumper clips would be carried in your pocket along with it. These were normally carried by signal and test man. Working on Telegraph circuits. As a faster method of pulling out your actual test set that had a line meter a battery, and usually a couple different Sounders to change the line current

I kind of want to figure out how to make one

Wow! it is antique! like telegraphic sound device but question is that how they decode ??? interesting.

cool

I'm the 666 subscriber. Oh dear

What people do not understand is Morse code is universal and doesn’t have a expiration date

James bond’s signal intersecting device

My great grandfather had one. The way it worked ( the way he said) is that they would find major telegraph lines and wire tgem through the watch and camp there for a few days. The changes in the telegraph line would do as the video showed. In his deployment he used one to transcribe 27 messages from Morse code. A problem they had though is that they would damage easily from over usage.

Нифига не понял

Not sure why but I thought of @CanadianMacGuyver for this one, Our OIwn Devices.

The first pocket phone.

👏👍

Very cool 👍

wow...interesting device, with a lot of style, thanks for showing it, it's strange that you are referring to something "presumably used", like a forgotten technology, this is very fantastic and intriguing, it sounds to me like those rockets that reached the moon or The speakers that JBL produced in the seventies that could not be surpassed, and their knowledge has been lost and it is now impossible or very difficult to build them, it really seems to me like an oopart that comes from a parallel reality that was forgotten by an interdimensional traveler, or uses an esoteric and ancient science such as the myth of tartaria. Presumably it can be an intercom that uses static aether luminirefos as the great master maxwel taught us

Thank you for posting! This piece of history is fascinating,

Somehow I don’t think this was a “Tester” so much as seeing it functioning exactly like a desktop Morse code device i actually bet that’s what it was a rich man’s Morse code sending device and it’s adjustability was because the signal line you’re using probably varies a lot, so … have a good one.

I was thinking this was a way to test the line when you mentioned what it was, but do you think it could have been used as a pocket listening device to bug a telegraph line with little to no fuss???

I can imagine these would have been used by Texas Rangers, Marshalls, Railway Men, and others for more than testing. To send messages on the line so that people in the local telegraph office wouldn't know a message was being sent or received.

I think it's a ring. You need AC electricity.

Its Morze alphabet pocket retranslator

Cool tool

The only thing I could think that would have been for testing would have been with telegraph was advancing to telephone and that might have been just Make sure that the current was traveling far enough to function

What an amazing piece of history you have! It can be said that I own an extensive collection of telegraph equipment and I can honestly say I’ve never seen one of these!

First smartwatch

....About the size of a Test lead ???, CHECK, and see If they're not the Size of 1920s Headphone Lead, Those were Pretty standard....

This is a old spy gajit it is to oprate mors code

Линии телеграфные и ящики прозванивать. Это для определения линии вслучаи поломок и налаживания. Короче телеграфные монтеры это носили.

That is the father of fidget toys😅

Could it have been a telegraph training device

Now THAT is COOL!

Beautiful !

Everything was great until the end when you put up the Hi-Res photos and slapped your logo smack bang in the middle obscuring anything worth looking at, Nice very nice.

I need that

A pager from the late 1800's, that's nuts lol

i know well and true i have no need for such a device.... but damn it i still kinda want one, thanks for sharing!

Wow, I had NO IDEA!!! AMAZING!

That’s a very unique and very cool item, thank you for sharing with us

I thought it was a communication device like you know, press the button to send a morse code and the other gear is for setting up some kind of frequency / channel…

that has mi6 all over it lol

What a beautiful piece, thanks for sharing

Amazing telegraph pocket watcher

Awesome, thanks for the video, I love obscure tech!

Interesting find. At first I thought it was some sort of spy equipment. Although there probably wasn't that much spying going on during the Victorian era.

I can only imagine the 1st text from a mobile device going something like this. .- -.-- -.-- -.-- -.-- ....... .-.. -- .- --- 😂

Super cool device. Never seen one before but I don’t know much about the telegraph equipment.

Spy tech from the civil war

ohhwas gunna say no way it was a recorder.

very awesome never seen one either thanks for shareing
