For an upcoming robot install, I was reviewing the process equipment in the paint robot arm. I found quite a “head scratcher” with the compressed air lines. I traced everything through and found that 3 compressed air lines are merged into 2 and then both the lines come into 1 inlet. I can’t understand why this wouldn’t have been designed to be 1 larger compressed air line?? It would be cheaper, reduce the need for adapters and clear up space in an already busy process arm.
Its about time to get rid of the 70’s yellow tub. Took some time but I think the new bathroom came out nice. The tiles are 1.5m long which definitely added to the cost but made install easier since this filled out the room perfectly.
Next in the premake series is potato gratin. This was alot more effort than I initially thought but I think it was worth it. I setup a workstation and to process everything and did some trials with different potatoes and different diameters. I tested different options and designs, I think the curled rose design was the nicest but it didn’t taste that well as the top would crisp up but the bottom was never that appealing. The best one was the gratin topped with caramelized onions and I will definitely making those again. I baked all of the samples in ramekins and then stored in the chest freezer. I found this to be a great option and I have used it many times when I don’t have time to make a side for dinner. I would throw this into the oven while I prepare the protein and the potatoes can hold well in the oven. Highly recommend. Also gives a fair bit of easy “class” to a meal.
For this winter I setup a automated grow tent to finish off my peppers and keeping my ficus/rosemary healthy. System was fully automated including watering and I went with a radiant heater to manage temperature (I find this much safer than trying to use a space heater). This let me harvest peppers deep into winter when there was snow on the ground. I think this system is great for extending the growing season.
I setup a watering system for my grow tent over the winter. I modified an cheap watering system with a nodemcu for a controller and a simple mosfet to run the pump. I tied into the existing system so I can use the battery. Overall it was a relatively simple modification and was able to set it up in esphome to run at 7am in the morning each day.
Next in the premake series is pumpkin soup. Similar to last time I made a large batch of pumpkin soup but this time I bought takeout containers and packed everything into them. They handled the freezer fairly well but microwaving didn’t heat evenly. Fortunately this is soup so a simple shake was able to mix it all through. Overall worked well but I feel like the french onion soup was something more worth to premake.
I recently got an espresso machine so now I have been hooked on making espresso martini’s at home. I am tuning the espresso for more crema (decreasing grind size and packing a bit harder). I also substitute simple syrup for chocolate liquor which pairs quite well with coffee.
I finally setup a monitoring system for my reverse osmosis system. I have 1 pressure sensor to track mainline water pressure, 2 flow meters to track usage and efficiency and 2 TDSsensor to track concentration. This was a pretty fun project and it was the first time I was working with a pulse based water flow meter, I had to calibrate it to match the measurements I was getting in reality. I even got a good video with the oscilloscope of the pulses while the system was running. Using this to set PMs so I am back flushing and replacing filters when efficiency starts to drop.
Had some production issues today where I was called for paint adhesion issues. I started looking into it and found that it wasn’t paint adhesion but rather plastic cohesion that was failing. I had a look at some other parts and was able to capture this amazing photo of complete peeling.
We had some solvent exposure at work that made for a good picture of solvent embrittlement on PC/ABS. You can see that that once the solvent flashes off you can see the plastic swells up and leaves opaque spots. I started doing some trials where any time there is some molded in stress I run some solvent rags over the part and it directly shows any surface issues. I also did some trials where I left PC/ABS in a can of paint solvent and the plastic completely deteriorated and turned into the consistency of wet cardboard.
