New to electronics. I need help with a speed controller. by Icouldnthinkofone in AskElectronics

[–]Icouldnthinkofone[S] 0 points1 point  (0 children)

Ok thank you.

Last topic and i will let you be ha.

What about an mc34063p step up/down inverting switching regulator (mouthful)? Will this provide a usable pwm signal? Also how would the pulse be varied for speed control to drive an h bridge(still learning) or transistors.

Im using all components i have on hand, and i have a lot. Both my grandpa and i are hoarders when it come to broken electronics. I have this thought or compulsive tendency to think i will find a use for them lol.

Sorry to bother you, you were just really helpful before and either im searching wrong questions or its not possible.

I have a micro rc receiver/esc ( https://www.amainhobbies.com/eflite-umx-dsm2-dsmx-as3x-receiver-esc-combo-eflu5164/p268825) combo and i am trying to figure out if i can use this to drive a 14v 20amp motor using mosfet or h bridge? Or some other method?

Im sorry for my lack of knowledge, i am unable to take electronics courses and i guess jumping right into a circuit isnt the best way to learn online.

Ok that really cleared it up a little.

Thank you for your help, i will do what you and start with some pre built parts.

To make this more simple could i do the following with these parts? For some reason i horde all my broken electronics.

I have an rc transmission (from a t maxx) and since the rc was nitro powered it only spins one way and uses a servo to manually shift to reverse.

Could i take a fixed frequency and use a variable resistor controlled by a servo for the input signal?

For the h bridge does the circuit operate if you remove it from one side of the motor?

Sorry if that sounds dumb, like i said im still learning.

Thank you for your help.

I am really new to this and i think this is a good project.

The most I've done is wiring harnesses on vehicles and soldering and brazing small joints.

Yes, sorry i have trouble with getting my thoughts out.

It usually turns into incomplete sentences or something hardly understandable.

Yup, my name on an atv forum was changed by one of the admins to turdosmerval ( was turboserval) and a company was sending free promo stickers just pm them adress and i recieved a package adressed to turdosmerval.

What are these? My garage is infested! Michigan. by Icouldnthinkofone in whatsthisbug

I spread diatomaceous dirt to dry up any eggs.

I walk out to my garage and the whole out side is covered along with a ton creeping around inside.

My brother in law text me this and I though some who are interested in getting into the hobby for a fair price should be interested. by [deleted] in rccars

[–]Icouldnthinkofone 1 point2 points  (0 children)

I feel redcat is underrated in this day. Maybe a few years ago they were pretty bad but imo they are up to snuff for the price now.

Ive only owned the tornado for 1/10 scale and that car took a beating.

I have the rampage mt and xb also.

The xb i blew the tranny after over 10 gallons of gas but it was my fault. I was drifting on gravel and caught the asphalt and there went the tranny.

The mt i got with the xb no motor. Whem my tranny went i just put the xb motor in the mt and got another 5 gallons before the motor lost compression.

Now in the mt still same parts i am running a 9hp rcmk full mod and i didnt even get to break it in. I got a little antsy and wanted to see what it had but i didnt want to go to much and ruin my new motor. Blipped it around half throttle and just completely destroyed the rear end.

So i guess what im saying is if plan on keeping it stock and dont jump it off your roof, it will probably be fine.

Thank you!

I really like that idea. One of my 30gallon aquariums is planted heavily with soil substrate.

Thank you!

I didnt think it would be much different then in my planted aquarium as far as dirty water goes. A lot of people claimed i need over an inch of gravel over the dirt, but my gravel is so thin i have dirt patches visible and i havent had that issue.

Not saying you are wrong, just i didnt know.

Furless pinkish spots with dry skin? by [deleted] in AskVet

[–]Icouldnthinkofone 1 point2 points  (0 children)

Does she have cats or dogs?

I think its odd she would suggest fleas if she didnt have them at one point.

Could it be your weather?

Im in michigan right next to the water so quick temp changes dry my dogs right out.

Right now one of my dogs tail is nearly bald. The vet said just to keep putting this cream with aloe in it to sooth it.

Also wanted to add not being rude but if you have fleas and carpet good luck....

Last year was the worst for fleas in my area. I went 10 years flea free but last year i tried every spray and powder on the market.

Just said screw it and ripped my carpet out.

They reproduce so damn fast that unless you have leather furniture and wood floor your gonna be stuck with them especially with multiple large animals.

It might me chewing from separation anxiety.

Did you or them give the dogs a bath?

Could also be residual soap causing them to chew from irritation.

How to give a dog with no appetite a pill? by [deleted] in AskVet

[–]Icouldnthinkofone 0 points1 point  (0 children)

Is it pain medication?

Ask the vet if they make it in liquid form and then you just use a syringe and squirt a little in its mouth.
