Hi Experts

I am having a problem trying to diagnose a problem I have with a simple high side switching circuit that is on a PCB. It works fine on a breadboard. The schematic is below. RL is a placeholder to where the rest of the circuit goes. The rest of the circuit I dont think matters because there should be no current draw if the mosfet if off. Please see attached schematic.
It is supposed to work like this. I have a microcontroller controlling the power to the circuit. To turn on the power I set the IO pin high and the Mosfet to M1 turns on and so grounds the gate of M2 and so switching M2 on. This all works fine.

The problem is that when I set the GPIO low I get 0V at the output of RL but if I measure the curent draw its around 150mA. This should be 0 or maybe just a few uA. Shorting R2 to ground has no difference.

I am having trouble finding out out to troubleshoot this and why this would be. Any help in how I can find the problem would be great.

Are these symptoms indicative of a faulty mosfet or something else.

Thanks!

This is using Amazon web services. This EC2 instance was created using Elastic beanstalk. Using this Elastic Beanstalk, 1 EC2 and 1 S3, plus some other components are created. This EC2 is also having php and MySQL, so it is a LAMP server. It is used to serve dynamic web applications.

Now, I want to setup cloudfront for SSL cert and faster data delivery. I follow the normal steps > choose web delivery, configure origin, distribution, and cache behaviour. I also made use of the route 53 for the public hostname to be pointed to relevant cloudnet. I waited this cloudfront distribution to be "deployed". However, when I access to the web with https, an error message prompts:

cloudfront attempted to establish a connection with the origin, but either the attempt failed or the origin closed the connection.

What would be standard ways of setting up this cloudfront to work with EC2 (LAMP)?

Thanks,

I have the need to get a BOM with all components , currently using Tc. CK86 , but this doesn't give enough information, so I want to do this by SQL, I come from oracle background and dont know how could I get this done in DB2 R/3, I do not have access to query builder or quickview , but i do have read access via SQL, I'm currently trying to figure out a way of getting this info using tables :

MAST Material to BOM Link
STKO BOM Header
STPO BOM item

Does any of you  have a solution for this?

In Oracle I did something like the following:
SELECT DISTINCT LEVEL
	,sys_connect_by_path(msil.segment1, ' @ ') AS "BOM TREE"
	,msi.segment1
	,lpad(' ', LEVEL, '') || msil.segment1 Cod_Component
	,msil.item_type
	,msil.description Desc_Component
	,BIC.component_quantity
	,msiL.primary_unit_of_measure
FROM mtl_system_items msi
	,bom_bill_of_materials bom
	,BOM_INVENTORY_COMPONENTS BIC
	,MTL_SYSTEM_ITEMS MSIL
WHERE msi.organization_id = 332
	AND BOM.ASSEMBLY_ITEM_ID = MSI.INVENTORY_ITEM_ID
	AND BOM.ORGANIZATION_ID = MSI.ORGANIZATION_id
	AND bom.bill_sequence_id = bic.bill_sequence_id
	AND nvl(bic.disable_date, sysdate) >= SYSDATE
	AND BIC.component_ITEM_ID = MSIL.INVENTORY_ITEM_ID
	AND Bom.ORGANIZATION_ID = MSIL.ORGANIZATION_ID
	AND msil.inventory_item_status_code = 'Active'
	AND msi.inventory_item_status_code = 'Active' connect BY prior bic.component_item_id = bom.assembly_item_id
	START
                  WITH msi.segment1 = trim(:parte)
        ORDER BY 2

Please provide me with recommendations for purchasing the best heavy duty backpack that will be able to carry three laptops.

I have already gone through several backpacks that simply aren't very heavy duty and develop problems like zippers unzipping and holes because they are unable to support the weight or bulkiness of carrying three laptops.

Hello Everyone.
I'm an Exchange Server newbie. I'm trying to set some server components state, and I found something.
I'd like to know there are multiple "-Requester" parameter value, so anybody please tell me: What's the meaning of each Requester value?
Example:
Set-ServerComponentState $Server -Component HubTransport -State Active -Requester Maintenance
Thank you so much

Running Windows Server 2016 Essentials. Windows server Backup completes 'with warnings' 9 nights out of 10. The message is: Bare metal recovery backup and system state backup both report One of the system components is not consistent in the shadow copy created for backup. Detailed error message: The writers timeout expired between the freeze and the Thaw events. Can anybody help me find out what is causing these VSS writer timeouts?

I have a Windows Server 2012 R2 Standard server with a very strange issue that I can't seem to solve.

Windows is fully up to date and an SFC scan comes back clean reporting no issues*.

*There were some issues previously that I repaired with SFC and DISM that did not seem to have any effect on what I am writing about below.

After about three to four days of up time this server will start having application crashes appear in Event Viewer and the server will start missing scheduled non-interactive tasks like server backups. The applications that crash seem to be exclusive to Windows components themselves: wbadmin.exe, ceipdata.exe, aitagent.exe, lpremove.exe, & schtasks.exe are the ones that I see consistently every time in the logs.

I have attached snippets from three separate crashes:
ceipdata.PNGdefrag.pngwbadmin.png
Once this starts happening services like the scheduled defragmentation of the drives and Windows Server Backup will miss all of their schedules with a corresponding application crash in the Event Viewer. The only remedy I have found to keep the backups running is to restart the server after hours every couple of days. It is worth noting that if I manually run the defragmentation or server backup it runs and completes without issues.

Given that the applications only seem to fail when not initiated from the GUI I started looking into issues revolving around non-interactive Windows tasks and came across this …

Yeti Cooler, Amazon eGift Card, and Movie eGift Card!

Does anyone know where I can get a PCIe version of this PCI card?

http://www.ebay.co.uk/itm/PCI-32bit-to-2xUSB-2-0-2xPS2-PS-2-Port-For-PC-Keyboard-Mouse-Combo-Adapter-Card-/152204959967?hash=item23701f60df:g:x1YAAMXQ4uJSDj6y
Note: The USB ports on the above card are totally irrelevant.

I need to connect a new PC to a old KVM setup that uses PS/2 for the mouse and keyboard.
(The PC has one of those combo Purple+Green PS2 connectors which I can only get to work on a keyboard)

If such a PCIe card does not exist, have you any other suggestions?

Does anyone know how to have Windows Search look in SharePoint as a location? I have went into gpedit, Computer Config - Admin Temps - Windows Components - Search and Enabled "Add primary intranet search location". I added the SharePoint site to there, ran gpupdate /force, rebooted and still nothing.

Any ideas? Thanks

Hello all,
    What is a good UPS (battery backup) that has at least 5 outlets and network email notification? Does not have to be huge, just for 5 pieces of network equipment in a rack in our factory. Something like 1500va, but it needs to be able to email out, as there is no PC in that rack. If anyone can recommend anything, I would appreciate it.

Thanks,

I've built a flight simulator.  Now I want to put lights in it, plus console LED's, plus a bidirectional motor to extend/retract controls.  I'm a programmer by nature, and just starting in Arduino/electronics.  I'd like all of those components to be controlled via the PC via USB.  So, a few questions:

1. This is a lot of components drawing a lot of power, I have sufficient pins on an Arduino to control them all, but for power concerns do I need to make 3 separate devices (Lighting, Console LED's, and Motor) or can I run them all from a single Aruduino connected to the PC via USB (and AC power supply, if needed).

2. I know about the individual aspects needed for those, as in, I can light LED's, and I know I need an h-bridge for the motor to work in both directions, but can those be done on the same board? If so, can someone give me some sketches or designs on how to do it?

The Lighting LED's are RadioShack 39.3" (1m) Tricolor LED Strip for Arduino 2760339.  The console LED's would be somewhere between 5 and 10 multicolor single LED's I need to color from green, to yellow, to red.  The motor (and I could use some advice on this) needs to spin a threaded rod that will push/pull the drawer the controls are mounted on.  

If someone can either provide me with good drawings/sketches, or point me in the right direction, I'd appreciate it.  I'm an expert programmer, but just learning electronics, maybe halfway through the tutorials.
Thanks,
-Chris
