Okay… nothing magical here. Just a boring old “Hello World”. There doesn’t seem to be any sample code for the newer enhanced mid-range PICs with a LCD that I could find online; perhaps you can find something better with Google than I will. I promise you two things with this code: It’s fresh off the…
It’s Friday, my wife is off head-shrinking so I decided the first thing out of the box of goodies I just got from Digikey was going on the breadboard. Okay… so I lied to myself: a 74HC14… those are just restocking parts from a project I was working out that W2AEW had posted on his YouTube…
Slowly chiseling away. I got the terminals set up, all the motor set up, disabled most faults in advanced configuration and I now have the drive out of fault, temp sensor back working, and ready to drive waiting on the DC bus. I think if I read the manual right with my configuration that should…
I said I was going to wait until I had enough batteries to start this drive up but I decided I couldn’t wait. I took a 110VAC to 42VAC power supply that was lying around and fed that into the secondary of the fan transformer (690VAC tap). Through an undersized bridge rectifier I need to…
I removed the input AC components today. The drive had a lot of weight in components just to drive a 110V fan. I’ll obviously have to replace that AC fan with a DC fan. It won’t have the CFM output of the original but I won’t be generating the heat it had. This monster was…
If you’re reading this, perhaps you’ve run across the endless forums of magic battery revival modules, advice for adding acid, water, salts.. whatever? I spent a solid day reading/surfing.. maybe there are a few magic ways to save your batteries? I don’t know lets see… but before I start let me say one thing: Have…
First off I’ve been really tearing it up in my nerdery the last two weeks… It’s messy.. That happens so don’t mind the mess. So I scored this sweet variable frequency drive (VFD) or also known as a VSD. It’s a Rockwell Automation drive that is to large for my application but it’ll work just…
Hardness building the last few days.. I chose a combination of .093 and .062 MOLEX connectors because I have a ton of them… and Vetco Electronics has a ton of surplus ones (at .59/.79 ea).. if you want to dig and find matches to… (hint, only like 10% of what they have has a matching…
I got got home to take delivery of this front end frame piece. Now I’ll be busy this weekend working on electronic steering. The PIC 16F1509 will be controlling all steering functions. I’ve written a remarkable amount of code for how long it’s been since I worked I a project with a F628A and 18F1330…
