Homemade 100 HP Motor Controller for an Electric Car

by MPaulHolmes

This instructable explains how to build your own 100 HP (peak) motor controller for use in an electric car or

motorcycle conversion. It can take any voltage up to 144v, and the peak current is 500 amps. The cost of

the components is a few hundred dollars, which means you can save over $1000 by putting one together

yourself. At 144v, you can expect a top speed of around 75 MPH in a car.

Check out http://ecomodder.com/forum/open-revolt-open-sourhttp://ecomodder.com/forum/open-revolt-open-source-dc-motor-controller.htmlce-dc-motor-controller.html

if you want to read about the whole story!

Experience in soldering is important. If you want to really keep costs down, a mill is helpful, but that work

can be outsourced to a local metal shop.

You are going to need a control board and etched power board. The power board needs to be at least 3 ounce copper. Ebay is a good place to look for heavy cheap copper clad PCB. For example:

http://cgi.ebay.com/25-shts-Copper-Clad-Laminate-FR-4-060-9-x-12-3oz-/310244821519?pt=LH_DefaultDomain_0&hash=item483c084a0f

You could print the picture from this link and somehow transfer it onto a piece of heavy blank PCB, and etch it with a dremel if you have a ver y steady hand. The dimensions are 8"x6". This link also has the G-code that you can use to etch with a CNC mill or you could give the G-code to a machine shop.

Picture 2 and 3 below is an example of an early power board I made with a Dremel.

You can get a control board from me or you can make the control board in your favorite PCB layout software using the schematic here::

Projects

I really enjoy working on projects. Much of what I do is software oriented, but I also enjoy electronics and other hands-on opportunities.

Software projects
Hardware projects
Other projects - such as hybrid hardware & software projects, or even completely non-technological projects

To-Do List

Here is a list of projects that I want to do, some are partially implemented as proof-of-concept, while others are mere ideas:

Repository management system. Needs to handle: git, hg, svn, cvs, fossil, etc... Provide simple mirroring and update features, etc...

Plant pot water level sensor. Raises an alarm when the plat needs watering - perhaps even one day turn on a tap too??

Pulse Oximeter. I've always liked the idea of developing medical equipment, this sounds easy, and I'd like to have one!

Smart PC Power Control/Monitor. I've got a basic power control and monitor setup for my PCs, but I'd like to develop this to a less prototype-esque state. Key features are remote power state monitor and control, and remote reset. The module acts like physical switches and runs on it's own... sort of like HP's iLO and Dell's DRAC, but as a retro-fit accessory.

Atmels ATmega48 (or ATmega88 for smarter ones) that does all the work. For some weird reason Chinese manufacturers LOVE ATmega48, it is in every design. Like always it is clocked at 16MHz with resonator. AVR in this design is in QFN package, in most of the cases TQFP is more common.5V voltage regulator in D-pack and some ceramic capacitors.Maxim MAX662 12V 30mA charge pump for high side gate driving. The output of the charge pump is stored on the ceramic capacitor on the right.

International Rectifier IR2101S high and low side mosfet driver. One for every channel. On the right of every driver there is a diode and a capacitor. This is probably bootstrap circuit that collects higher voltage for gate driving from inductance spikes of outputs.

In between of gate drivers are resistors for feedback.

The top part is for BEC. It looks identical to very common switching regulator block used in ebay products. Texas Instruments LM2575, originally a 1A step-down but now apparently a 5A one.

http://www.eevblog.com/forum/reviews/eumax-digital-ultrasonic-cleaner-teardown-and-review/

This is a new line of MemoryQuick ultrasonic cleaners from Eumax, and the only thing new is the memory button that preserves your settings in case you need to leave the room and "pause" the cleaner in its work.

The model is http://www.eumax-cleaner.com/en/pro_show.asp?id=17

Its a wide model with full tank capacity 2 L. However you need to take in account when buying one that you can fill approximately 70 % of tank with liquid and that comes to 1.4 L of useful volume.

The units is quite simple and good quality at first look. The maximal setting on the timer is 30 minuttes and on the heater 80 C. Nice thing about the unit is that you get metal mesh basket while some other manufacturers sell it separately.

Although it is made of stainless steel it is a lower grade (i cant surely claim which type) and they are somewhat saving money by not including the outside of unit with stainless steel screws since the unit can be moist at times of changing the liquid. The handle on the lid is made from low quality plastic and comes already half broken.

I got the unit mainly for cleaning my CNC router bits. Since im using a carpet tape to fix the blank PCB to the work table the bits get contaminated with glue and PCB material dust sticks to them. I bought similiar 50 W product in local electronics store but it did not work as it should because you can see it does not use proper transducer (the last photo) which is not 50 W as stated on the package.

The inside build quality is good and simple. It features a SMPS power supply for the transducer and heater. The SMPS is controlled by the board on the front of the unit which is powered by a small transformer and on board switching regulator.

Regarding the cleaning efficiency it is superb! I throw a handful of glued and full of dust CNC bits inside, added water, 2 drops of dish washing detergent and set the temp to 30 C and timer to 5 minutes.

They come out so clean like new, and whatever i thrown at it later came out as new. Since this unit is a genuine with proper 50 W transducer it really cleans and im perfectly happy with it.

About

You’re looking at a weblog maintained by Jean-Claude Wippler. “Jee” stands for JC’s environmental electronics.

This is the place where I report on my adventures in “Computing Stuff tied to the Physical World”. I’ve started working on some hardware / firmware / software to better get to grips with energy consumption in and around the house. I’d also like to automate things a bit more, but only to the point where such domotics really feels like a genuine improvement. My goal is to reduce the number of gadgets and appliances where possible, not to add yet more non-intuitive technology to my living environment.

I’ve been a self-employed IT consultant for some 20 years now. I have a masters degree in mathematics and computer science and have recently re-discovered my passion for stuff that does stuff – with a meaningful purpose, preferably. When I found out that small MPU chips are now powerful enough to perform fairly complex tasks, can be programmed in plain C / C++, and are amazingly affordable, it was like a dream come true. A lot of things are coming together for me in this new idea space.

LinuxCNC 2.7.0 Released!

Fresh install instructions. Updating from 2.6.x instructions. Release (changelog).

Last Updated on Sunday, 06 September 2015 11:43

LinuxCNC: Software for realtime control

Welcome to the home of the LinuxCNC

Here you'll find information about the software, how to get it, how to configure it, how to run it, and especially where to ask for help.

Community maintained wiki with lots of information and examples about configuration and using LinuxCNC.

LinuxCNC is a software system for computer control of machines such as milling machines, lathes, plasma cutters, cutting machines, robots, hexapods, etc.

LinuxCNC is Free software released under the terms of the GNU GPLv2 (General Public License version 2).

LinuxCNC is a descendent of the original NIST Enhanced Machine Controller software, which is in the Public Domain.

LinuxCNC has many exciting new features and brings a lot of new functionality (a flexible and powerful Hardware Abstraction Layer that allows you to adapt it to many kinds of machinery, a software PLC controller, easier-than-ever installation, a new trajectory planner, and more.)

LinuxCNC is precompiled with Debian Wheezy (or, previously, Ubuntu LTS) for ease of installation and longevity.

Note: Do Not upgrade the Linux operating system from the installed version as it will prevent LinuxCNC from working as a specific kernel is required.

AVAudioSession bluetooth support

December 17, 2014 Nikola Sobadjiev

Adding Bluetooth audio support to an iOS app

[session setCategory:AVAudioSessionCategoryPlayAndRecord

withOptions:AVAudioSessionCategoryOptionAllowBluetooth

error:&error];

Switching to bluetooth

- (AVAudioSessionPortDescription*)bluetoothAudioDevice

{

NSArray* bluetoothRoutes = @[AVAudioSessionPortBluetoothA2DP, AVAudioSessionPortBluetoothLE, AVAudioSessionPortBluetoothHFP];

return [self audioDeviceFromTypes:bluetoothRoutes];

}

- (AVAudioSessionPortDescription*)builtinAudioDevice

{

NSArray* builtinRoutes = @[AVAudioSessionPortBuiltInMic];

return [self audioDeviceFromTypes:builtinRoutes];

}

- (AVAudioSessionPortDescription*)speakerAudioDevice

{

NSArray* builtinRoutes = @[AVAudioSessionPortBuiltInSpeaker];

return [self audioDeviceFromTypes:builtinRoutes];

}

- (AVAudioSessionPortDescription*)audioDeviceFromTypes:(NSArray*)types

{

NSArray* routes = [[AVAudioSession sharedInstance] availableInputs];

for (AVAudioSessionPortDescription* route in routes)

{

if ([types containsObject:route.portType])

{

return route;

}

return nil;

}

- (BOOL)switchBluetooth:(BOOL)onOrOff

{

NSError* audioError = nil;

BOOL changeResult = NO;

if (onOrOff == YES)

{

AVAudioSessionPortDescription* _bluetoothPort = [self bluetoothAudioDevice];

changeResult = [[AVAudioSession sharedInstance] setPreferredInput:_bluetoothPort

error:&audioError];

}

else

{

AVAudioSessionPortDescription* builtinPort = [self builtinAudioDevice];

changeResult = [[AVAudioSession sharedInstance] setPreferredInput:builtinPort

error:&audioError];

}

return changeResult;

}

Wow, that was a lot of code! Well, the important bit is setting the preferred input in the last method. The other code is just to get the right AVAudioSessionPortDescription object for speaker, earphone or bluetooth.

Switching to speaker

While there are other way to do that, this is what I prefer to use:

- (BOOL)switchSpeaker:(BOOL)onOrOff

{

NSError* audioError = nil;

BOOL changeResult = NO;

if (onOrOff == YES)

{

changeResult = [[AVAudioSession sharedInstance] overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker

error:&audioError];

}

else

{

AVAudioSessionPortDescription* builtinPort = [self builtinAudioDevice];

changeResult = [[AVAudioSession sharedInstance] setPreferredInput:builtinPort

error:&audioError];

}

return changeResult;

}

Switching to earpiece

This one is easy. It’s just the opposite of switching to speaker:

- (BOOL)switchEarphone:(BOOL)onOrOff

{

return [self switchSpeaker:!onOrOff];

}

AVAudioSession bluetooth support can be a daunting task. And there isn't much information about it in the internet. I hope this article helps you with your task. Thanks for reading!
