So work wise I am not doing all that much. So the wife, who works in child care and is classified as an essential worker for the covid 19 response has asked me to make her some resources. I don’t mind and it have me a couple hours of doing stuff today other than watching the walls from within lock down. So i knocked up a set of letter disks and some boats. As i write this post, my wide is cutting out fabric and sewing some sails for the boats.
I have spent the last month worrying about my business, finances and not dying from The Rona. So yesterday I actually felt motivated enough to start working on a project I have had sitting here for some time. Got enough built where I could start testing things, turn on the PSU and it hooks up straight into current limiting. Hmmm, I have a short. So i go into diagnostic mode and start to deep dive.
It did not take me long to work out what the problem was, the regulator for the 3.3V supply rail used a different pinout than whats on the board. I had assumed that the 3.3v regs i had were all of the L78xx series, but they were not, somehow I had bought LD1117Vxx series which have a different pin out.
The only ones I can get locally in the same footprint are 50ma and I need a couple hundred ma. So i had to order from element 14 and they are god damn hopeless on a good day and do not expect to have parts for a week. I would have ordered from mouser, but i do not have the money to put in an order big enough for free shipping and I just dont need much at the moment.
The joys of home brewing HAHAHA. I now have hay fever like a MOFO and feel like i am dying. So I am going to dope up on phenergan and go to sleep for a few days HAHAHAHA. Too much information?
