In order for success to exist something opposite of it has to exist as well. For every up there is a down. For every left there is a right. It is only logical. In order to know success one has to know failure as well. They are inexorably linked – the only way to not know failure is to not know success. Society heavily favors success. Again this is logical. We are bags of mostly Read more…

I got a 20% off Harbor Freight coupon and got unreasonably gitty. I have been eyeing the 20 ton press and 20% off off ANY SINGLE ITEM* was something I felt was worth waiting for. But wait, what is that excitement tempering asterisk? I have reformatted for readability: *Cannot be used with other discount, coupon or any of the following items or brands: Inside Track Club membership Extended Service Plan gift card open box item Read more…

I have been playing with the latest revision of the VPSB (Vic’s Power and Serial Board). I was hoping that this would be the last revision, unfortunately the fact that I crewed up the power supply footprint will prevent that from happening. I got the pin order backwards. This is the worst kind of failure since I can’t blame anyone else. Anyways, here’s the potato-cam picture: You can see the power supplies in the Read more…

Long story made short: more failure. One very basic failure was mixing up SSOP footprints with TSSOP footprints. I have a laundry list of excuses for screwing it up, but at the end of the day a lesson has been learned that should have been learned many times over in the past – don’t try to hand-wave things away. Experience is the name we give to our failures, I suppose. A more subtle failure was Read more…

With the gate driver IC and the MOSFET in possession, it was time to experiment. Below is a potato-cam(tm) pic of the layout. Fun fact: initially I forgot to hookup the ground on the gate driver chip and spend 30 minutes scratching my head. It’s hard being dumb sometimes. So what we’re seeing on the right hand side is the 8 pin gate driver and below it to the right is the MOSFET. I am Read more…
