An additional two different high side test boards were sent in today. So I will be testing the 1EDI EiceDRIVER, IRS25752LPBF from Infineon and the other Si8271 single, Si8275 duel drivers from SkyWorks. I sill have a week left on this residential remodel so when finished I can concentrate on the mechanical and electronic builds.

JLCpcb just finished my boards and are being shipped. I have the parts ready and waiting form Mouser but still need to order the parts for the Skyworks duel driver. I am hoping one of the two will work out great as the prices are redic these days. As soon as the boards are in the testing will commence then maybe I can get this ball rolling faster then a turtle in heat lol!

Just received my test boards and my last Mouser order will be in tomorrow. The bad news is I start another remodel job Friday so it could be Monday or Tuesday until I can get to it. Also emailed two suppliers for the STP46NF30 Mosfet which have them the cheapest anywhere right now. $1.70 a piece.

well it was a sad day when i was to work on the test boards and realize I can't find my SMD solder anywhere. So it looks like I need to order more solder and flux. Funny I always keep it in the fridge so I must of left it at my old place months ago hahaha! There is no local supplier in the hick town I live at so ordering is a must.

Solder will be here tomorrow but I will be on a house exterior job for a few days so it has to wait. Some time next week I will assemble board and test by next weekend. If the duel channel works out well I will save 120 dollars on the expense of electronics.

Ha, ha, ha! I attempted to work on the high side boards without my huge magnifying glass, boy was that a mistake!. It broke during moving so I have to dig out the JB weld and fix it. Mine was purchase from a thrift store for like three or four dollars and I modified it for my liking. I need to replace the light also so I will convert to LED lighting on three sides. The glass is like 5 inches so I can see with both eyes lol! Boards will be done by this coming weekend and I will test posting my results.

Quick update, Found some SQP10250E's for a very good price which is one of the transistors I was testing out. They are as cheap as I have ever seen them and I need them to keep me from having to use To 247 or 3P which will make the board much bigger. I want to stick to the To 220 which shaves many inches off the switching board. I am purchasing 65 of them because the IGBt's are just to slow. I can get them for 1.77 each which is amazing in today's standard of 6 to 12 dollar transistor price gouging BS.

If you want to know why there was such delay in my electronic switching I have to say I just don't have the eyes I used to and can't see the board parts without help. My work light magnifier got broken during that last move and I just now got to it. This thing is worth it's weight in gold because of just how large the glass is being able to see with both eyes and have a bright light. I use helping hands with this also but right now it is repair time lol!
This thing used to be three feet long and broke in the thrift shop but I had to have it as these large glass one's are hard to find now. JB Weld to the rescue and a new light mount and I will be ready to solder my ass off. I also have some silver solder paste I want to try out which is suppose to be way much better then regular shit solder.
All in all a good find for four bucks and a little TLC makes this a win win item especially for my blind ass lol!
