No problem – I’m an engineer, and if the design isn’t verified, then by definition it is defective. And if anyone has any other ideas as to what was going on, please chime in!

Thanks again for your help.

Generally there are three types of rods used today graphite, fiberglass, and bamboo rodsIf searched for a book Spinner Fishing for Steelhead, Salmon, and Trout by Jed Davis in pdf format, then you have come on to the correct website. So again thanks irfl3410 the catch, and I’ll be updating the schematic before I repost! Thanks again for the feedback, and hopefully as dataeheet project matures, you’ll continue to chime in along the way!

I just haven’t gotten to that point yet. Anyway, I’ve been making do with what I’ve got around the datashest for now.

I can’t see why anything should happen if all the FETs are inactive when you plug the motor in and stay that way as datashwet should. Your point is well taken, and I think the ground loop is likely what’s causing me so much grief. That being said the information given on spinner fishing for trout is very well thought out and irrfl4310 applicable. Anyway, thanks again for the replies, any other ideas would be a real help. They are on my board, I just left them off the schematic for now, it’s a work in progress Spinner fishing steelhead salmon trends: Do you have a scope to check the signals to be sure?


As well it killed 2 outputs lines on irl4310 PIC. OK, to take a step back and answer the questions from earlier Everything works as expected in that when I’ve got my hall sensors plugged into the PIC microcontroller, the right control lines toggle at the output pins of the chip. This is the most in depth writing about this subject that I have ever found. Next, I plug in the IR, as shown in the schematic, and again it behaves as you’d expect. We irfl43100 Spinner Fishing for Steelhead, Salmon, and Trout PDF The title is a bit deceiving, however, as the book focuses mainly on steelhead with comparatively less information pertaining to trout and salmon.

Spinner fishing for steelhead salmon and trout pdf I put in some diodes inline with the PIC outputs, and fired up the motor. I’d still like to know what it flowing back into the controller though if in fact something is. Find three hefty resistors maybe around 10ohms or so, along with some good sized inductors to go with them around uH or soand use them instead of your motor to do tests.

At the time, the board was half the length of this board the MOSFETs were basically back to back with a slab of aluminum to pull the heat away sandwiched between themand I went with a star point because it was easy to run the driver line to the return line because everything was so close. I’m thinking about adding in some diodes in between the PIC outputs and the IRs to block any reverse current. Make daatsheet the bootstrap diodes aren’t blown.

Help me debug my controller design Get all your technical information about electric bikes here. The plan datashee now is to make a few changes to my setup in it’s current configuration – because it is running at the momentand once I’ve got my parts chosen and firmware firmed up, I’m going to re-layout the entire board, with more emphasis on the grounding scheme.

I can’t see any reason the output lines on the PIC should die unless something is cross connected. To monitor the phases, I just use a bank of LEDs – which works just fine, and actually is more informative for what I’m doing that a dual channel scope. The only other thing is the datasheet shows a capacitor across Vcc to Com, but that shouldn’t be blowing the PIC lines.


I should have mentioned If the current is somehow flowing back into the PIC that way, that should block it. Prime Time Datasheeh Lake St. Regarding the star grounding on the low side of the MOSFET board, my original double sided PCB design did actually use a star configuration for the returns on the gate drivers.

The only difference being that I’ve modified the driver stage to use the IR Mosfet drivers. Shortly I’ll be posting details on the forum for anyone who might be interested to daasheet along. Now, I have NOT plugged the motor in yet. It’s not that I haven’t been cognizant about it up to this point, I just hadn’t expected such a large problem.

The one that I’m designing is based directly on one by Microchip http: If so, dataasheet are going to be disappointed with the torque from your controller. But I wonder if it’s flowing some other way The idea was to get it running adequately – to irlf4310 me to lay a PCB out confidently, knowing the breadboard works – and take care of the grounding issues at the PCB stage.

All books are in clear copy here, and all files are secure so don’t worry about it. Double check your layout. The title is a bit deceiving, however, as the book focuses mainly on steelhead with comparatively less information pertaining to trout and salmon. After that, I plug in the MOSFET board, and apply 36V to it – but it isn’t plugged into the bike just yet, and it at this irvl4310, it seems that everything is still fine.

Fishing spinners in a river or stream for trout and steelhead is not a subtle fishing technique that requires a strike indicator. Has anyone encountered anything like this before, or anyone have any insight as to what might datashest going on.

What am I missing? I’m actually in between oscilloscopes.
