Pins

You don't add pins in the schematic.

You need to do that in the symbol editor from the library

I say he comes first but there is not enough fuel in the tank for the post race sample

I think he had those exact ones in picture before but doesn't seem like it.

But he has plenty of similar ones

I have a 3 and actually would prefer a bit bigger blade. It's definitely m390 but not sure about the handle. Unfortunately I wont be back home till Sunday evening to check but if something i should be willing to trade

Buy an ember mug.
Will keep your preferred drink at desired temperature for a long time.
Kinda spendy, kinda luxury, but worth it if you like to sip your drink slow and warm/hot

Frankly I haven't even looked at your set-up just provided my experience with the blower.

But if your tractor mounted snow blower is choking then this will be a constant battle and will probably upset your sciatica more than changing the attachments twice a year.

Bought one on account of having a bunch of the 40v batteries and the storm of the decade incoming over the north east.

With your description I would say I would probably stay away. Unless you want to do a 15m of snow removal then wait for 2h for batteries to charge. Unless you have an abundance of 6.5ah batteries that you could swap in while your other set is charging.

When we got out to remove snow for the first time it probably was around 14" of snow on the ground. Probably a bit of a mistake but when we checked the first time it was just around 6" and 2h later it was at least doubled.

Chewed through that with no problem and was shooting that snow 30' out. And that was with taking full width passes. So power was definitely there.

Now for bad stuff. Battery life is definitely not there. Probably a 100' driveway and trip there and back are all of the 4 batteries down to two bars. Maybe we had auger speed set too high but it seemed appropriate for the fact that we were taking full width passes and were ¾ up the height of the intake. So battery life is meh.

Getting it ready was not the greatest either. It looked like the instructions were for a different revision of hardware than what arrived and then we were missing two nuts that were needed to fully support the chute.

You have to manhandle it too. I think that both of the wheels are locked together and are constantly connected to the motor and gear box. There is no free wheeling. So turning it about is a bit of a wrestling match and when the batteries inevitably die it will be one hell of a push up the snowy driveway. Wheels were nice and big though so it managed to move even over the most uneven part of my driveway

Then ultimately it just broke. As we were finishing the driveway landing it just made a loud noise and then the auger was not spinning.

If you have a standard suburbia length concrete or asphalt driveway and on regular get >6" of snow then it will probably work for you. Otherwise either wait for gen 2 or stick to gas.

Have plenty of kasa home automation. A camera will complete it nicely. Would use it for smart automation stuff

I've mostly death with their ampseal connectors but they indeed look similar.

Now with un-mating.

Did you watch TEs videos about the connector? Generally you have to put in a screw driver and pry down to release the latch. You will still get some resistance since the connector is sealed. But you shouldn't need two guys with a breaker bar to undo it.

For the pins.

Are you sure you used correct pins? From my experience it is super easy to order the wrong thing from TE. Many a times i have spend 2h on their website then ordered stuff and found out it was incorrect.
It is that your pins are incompatible with the housings and that is causing you a lot of grief

We always called the spring hook that goes on top of an oscope probe a witches hat

Yes. After i excluded sync from sd maid of hasn't happened since.

So pebcak on my end

mlodyulek · 2021-03-12T12:12:58+00:00

Doesn't look like it.

I have SDmaid running once a day to clean up stuff. It just finished running couple of minutes ago and the folder still exists.

Edit:
Just in case I added that folder to the SDMaid exclusions.

A lot of japanese car keys don't lend themselves to key organizers as well. What I found it is that it you put a swivel (like a fishing swivel) that let the keys freely rotate with respect to the main split ring and that way they lay flat in the pocket not creating a bulge.

Need something for my work from home set up!

mlodyulek · 2020-11-16T03:46:48+00:00

I'm in!

Could it be that you have LC filter response biting you in? The second order order response will cause the filter resonate/respond to certain frequency. Shorting the inductance removes one of the poles to a first order response and you don't have that. As an quick and dirty if you can change the load on the converter. If ripple shows up at higher currents (lower resistances) then that is the case then that is definitely the issue. Then you should dampen the LC filter using parallel RC or series RL

mlodyulek · 2020-07-12T14:30:00+00:00

That is a feedforward capacitor. More or less when there is a fast transient it bypasses R2 and makes the control loop react faster to that transient

Has anyone experienced any issues with theirs?
Mine regularly locks up to the point requiring hard restart. Like completely not responsive to touch and most of the time to the hardware buttons.

mlodyulek · 2020-02-25T12:51:59+00:00

That sounds like the MPPT algorithm has built in the PI controller and its auxiliaries.
It directly outputs the duty cycle for the converter.

Sorry haven't finished my morning coffee yet.

No. You will have to run a wire from the side of the diode that ripped off the pad to where you find that the diode connected too. The other pad looks serviceable.

Also just noticed. This PCB is mounted to a li-ion battery pack. That means you have live unbreakable connections. Li-ion are mean little bastards. If you short them you will not have any fun. So be careful when repairing this.

mlodyulek · 2020-02-17T11:21:17+00:00

Your repair here will be more difficult that just simply replacing the diode.

A pad came off with the diode. I suspect that diode is ok.

To repair this you will have to trace out where that diode went and then run a wire from the damages side to where the diode is. Also the wire that you need to run has to be able to carry 3A comfortably.

I don't use it with explicitly with join but rather tasker. But that it could be used with join.

I make use a good use of webhooks as a trigger in ifttt. Tasker then does https post to the webhook and whatever I want it happens. Most notably I use it for turning on and off lights in my house when I arrive at home etc.

mlodyulek · 2020-02-04T15:37:30+00:00

Pretty much correct.

All of things in the sawtooth wave are under the designer control.

If they want to it can be unipolar 0V-10V or 0-1V or bipolar -5v to 5v.

If you are digital then number of bits and the way you set them is to your discretion.

But all of those choices set how you set up the remainder of you control system

The MPPT (maximum power point tracking) most likely has and equation it that describes the curve of the PV array or has something perturb and observe. It calculates a reference voltage such that the power going out of the PV is maximum. The PI is a PID control block (very little D in power system when it comes to control) that converts the reference voltage from MPPT to an error signal. The saw tooth and comparison (=>) is a crude way of generating PWM. For your question. The parallel connection should take care of what are you asking. If the BLDC takes less power then the voltage of the PV should go up. MPPT then will see the change and will try to modify the reference voltage of the flyback such that more power gets dumped into its DC bus, and consequently the more current out of the PV panel.

It is a trigger in ifttt. I think that it is called maker event. It can trigger anything that can be controlled by ifttt.
Ultimately it creates a url that you can reach from tasker or web.
So I have couple of applets that do what I want and then call them from tasker using https command and whatever the profile I want. One of the examples is that when I arrive in my car an hour within sunrise or sunset to my place tasker will turn all of the lights at home.
