Down side of advertising in the yellow pages

I want to share my experiences dealing with the big phone companies advertising that publishes that real yellow paged phone book in Georgia as well as many other states or for our purposes we will call them Satan. It’s a story of lies, forgery, high pressure sales and thousands of business forced out of business a day. And a product that they charge premium prices for that at best is 3rd rate.

Satan talks a pretty good game claims that we’ll make $12 for every dollar we spend with them in advertising and that they will drive hundred clicks to our website for mere fraction of what you can do it for do it for yourself. In reality for every $12 we spend with them we might make one dollar and all that traffic they’re driving to our website unfortunately is either for products and services we don’t sell or for areas that we do not provide any service. We contact them to complain about this and they tell you that you don’t know what you are talking about. They also go on to tell you that they are certified experts. As the year continues on our advertising budget is just paying our advertising bill with Satan. You get ready to slash your budget with Satan at the next renewal.
Now it’s time to adjust your advertising with Satan to something you can afford. But Satan’s minions kick and scream all the time you explain that you have to cut not double your budget. You think you finally got your advertising with Satan down to what you can afford. But, you never receive a confirmation or contract for the new deal. It turns out that Satan changed your contact address to their office and forged your signature. By time we found out it’s to late it’s next year and our bill went up instead of down. Now the payments to Satan are cutting into our operating budget and it’s 2008 and the banks melt down causing business to fall off a cliff. We try to get some of the online services cut but they wont do anything until next year. We where not even able to find out what we are paying for. Just to try to keep the lights on we had to short the payment to Satan. In turn Satan has our internet, voice mail and call forwarding cut off. Ever tried running a business in the internet age off of a 56k modem. Thankfully they can not have our phone cut off since it is a regulated service and we are paying enough to cover that and a small portion of the advertising.
It’s time for Satan minions to renew our advertising contract. They come in so proud of all they ads they have in the phone book for us and how well we are doing because of the ads. We hit the roof SEVEN ADS 5 OF WHICH HAVE NOTHING TO DO WITH WHAT WE DO. To top it off most of the ads have the wrong phone number and address. We demand to know who authorized all this cause we never got a contract, order confirmation nor any answers what so ever on what we are paying for. The minion has no answers and says they can’t help us and leaves. By this time they are threatening us with legal action if we don’t pay them immediately. So Satan sends in his right hand minion. She tell us we are going to increase our advertising. We push back hard and tell her we are cutting the advertising. This goes on for over 11 hours over 2 days. We finally get it down to something we think we can afford. Unfortunately with all the unpaid bills from the forged contract, we are behind the 8 ball. Early in 2009 they cut off our advertising due to non payment of the outstanding balance. And the legal battle begins. They pretty much dictate terms that you will pay. We tried but business was still hard to come by and fell behind resulting in them seeking a summary judgment. Going to court was a waste of time they would not hear my business partners plea. So this is how it ends.

Everyday across this country 1000’s of businesses end up in court against Satan and I dare say it ends the same way for everyone of them. They come in thinking they are going to get their day in court to find out it is Satan’s day in court and weather you have proof of wrong doing or not, have an attorney or not the result is the same you loose and Satan has the right to loot the companies accounts and assets. So on this one day in this one court, 26 went up and 26 fell. Many will go out of business some will try to survive. We will go out of business.

As the fallen limp away through the ashes, you can hear Satan Laughing with delight.

Repair of a Channel Master D2A

After studying Amazon I picked this converter because the only negative review was over the interpretation of the description of what the unit was for.

Channel Master D2A

Channel Master D2A

It has worked well for years until it started to continuously reboot.  Rather than just replacing it I decided to attempt to repair the unit. I was pleasantly surprised when I opened the unit and found a separate power supply with through hole components.



Not only was there a separate power supply board but the supplies are labeled at the connector.

Power supply voltages

Output Capacitors

I made some measurements and found the power supplies output high. I static checked the components in the output side of the power supply and decided I would take a chance and change all the caps on the output side.
C10, C11, C13-470uf @ 16v
C12=1000uf @ 10v
C7=220uf @ 25v
C8=100uf @ 25v

Once all the capacitors where changed the unit worked fine.  I wasn’t surprised that the capacitors had gone bad because of the heat generated by the power supply.

Sub Contractor of a Prime Contractor on a Federal Contract. My Sad Story.

Before I share my story, I will share my advice on being a Sub Contractor for a Prime Contractor on a Federal Contract.  Assume that you will not get paid without a FIGHT.  So make sure that you take steps to insure you get paid even if the Prime Contractor hops a plane to Cameroon with the money.  A payment bond or the government pays into an Escrow account that the payments are distribute from and that the Prime Can’t empty by himself. Bottom line, you can not rely on the Federal Government ensuring that you will get paid.

Toward the end of December 2012 we were approached by a Federal contract holder, 8a Certified,  needing help with a scanning project in Atlanta.  This was a ongoing project lasting several years.  We started in December, submitted an invoice at the end of month and at the end of January 2013 we got paid as stated in the contract.  This should have been a good sign that they where going to up hold their end of the contract.  We continued the work and the Prime brought in another scanning company to take over his employees and to work along side us.  After he did that we slowed down our plans to scale up production.  We billed him at the end of January as did the other scanning company.  We continued through February 2013 at the end of February we submitted our invoice and waited for payment for January, so that we could scale up production. Payment did not happen.  We attempted to contact the Prime contractor, no response.  We then inquired with the contracting officer for the Government and found out he got paid just after the 15th of February. At the beginning of the second week of March we sent an extremely aggressively worded email to the Prime which got a response that they would be sending payment Friday.  Needless to say that payment never arrived.  We filed a complaint with the government but it was too late to stop the payment directly to him for the February invoice.  We ceased operations on the project until our contact could be reached.  Two weeks went by with no response from him.  We got word that the other company can not reach him nor have they been paid for January or February.  So at the beginning of April we went to the site to remove our equipment and to turn in our security badges.  At that time we where informed that the Prime had not submitted an invoice for March and that they would be cancelling his contract. Unless the Prime submits an invoice we would not be getting paid for March since we don’t have a contract with the Government. 

In the Months since we still can not reach the Prime Contractor.  All letters have been sent back as “Moved no forwarding address”, phone numbers have been disconnected.  We went as far as sending a demand letter to the registered agent listed on their corporate filings for the state of Virginia.  

How it stands now, the contract has been canceled and the president of the company we where a subcontractor for is gone as well as his employees.  It goes without saying that I didn’t get paid. All it seems to remain of the Prime contractor and it’s owner is a web site and a trail of short sold residences of the owner. However, The contracting officer would like to give us a positive review but we where not the Prime contractor.

Adding an Aux Garage Remote.

My purpose for this project is to add an additional remote controller to my garage door opener without making any permanent changes to the opener.  In this project I used the Visitect RF300R receiver and matching remote.

Decoding the outputs.  The receiver has 2 data outputs and an enable output.  The enable goes high when either button is depressed.  Data 1 and Data 2 latch high depending on which button was pressed last.  To allow me to add additional features later I decided to use the enable and Data 2 to control the relay to trigger the opener.  To keep things simple I constructed a simple AND circuit so that both signals had to be high in order for the relay to close.  This can be seen in the circuit diagram below.

Circuit Diagram

The AND circuit is made up of two transistors and the output of the AND is the relay. The relay contact is wired across the existing button on the wall for the opener.

Operation is pretty simple push the 2nd button and the relay closes for the duration the button is held.

Conclusion: This unit has proven to be more reliable than the internal remote controller. This unit also has proven to have a range over 50 feet. However post 9-11 I would not even try to go through any type of security with the remote that is paired with this receiver due it’s unusual extendable antenna on the remote.

Remote Control Door Latch

This is a hack I did to control a 12 vdc electric door strike.  Since I was doing this on the cheap parts on hand where used. I used a surplus power supply and remote control (Key Chain Remote).  The only problem using this remote control is that it’s output once turned on will stay on until it is turned off.  I rather have the output on only for a short time and then turn off.  Remote Door Latch CntrlSo I added some circuitry to accomplished this.  I also had to modify the relay in the remote module so that it connects the output wire to ground instead of 12 volts.Modified Wireless RemoteI did this by isolating the relay contact connection from the 12 volts and then ran a wire from the relay contact connection to the black wires of the remote.

This is the circuit I came up with to keep the latch coil from being left on.Wireless Door Latch

I am not worried about the mosfet operating in it’s analog region since the current through the relay is very low so the Mosfet will not get warm enough to be a problem.  (The device I used was a 10 Amp Mosfet.  It’s what I had on hand.) Also it should be noted that the coil for the latch has to be connected so that the circuit will function correctly.  Completed Latch Controler

Operation:  On button is pressed door strike retracts to release the door. If the Off button is not pressed the circuit times out after 12 seconds and the door release latches back and the circuit locks out until the off button is pressed. The preferred method was to press the off button on the remote so that it would reset and be ready for the next activation.  In practice this worked fine, in fact this unit was used for over a year until we relocated the office.

Conclusion: If I did it over I would use a lm555 as a on shot so that the turn off time for the mosfet would be faster. Below is what the relay K1 voltage looks like when it is allowed to time out.
K1 Voltage For over 2 seconds the mosfet is operating in it’s linear region. If the load was large enough it would actually cause the part to heat up noticeably, but being over-sized by around 800%  it’s not a problem powering that small pc board relay.

Louder Doorbell Hack

This is a hack I did to make a wireless doorbell loud enough to be heard over loud equipment and to give a visual indication of which door button had been pressed. For the visual indication I used two 4 inch CCFL tubes and for the sound I used a compact Siren. For the doorbell I chose the GE wireless Door Bell with two wireless buttons.OLYMPUS DIGITAL CAMERA

This is what it looks like inside.Inside_Doorbell The 14 pin IC is a 4011. By looking at the outputs of the NAND gates I found that Pin 4 Toggles with any button push and pin 10 toggles when I press the back door button. Scope View I chose to use a MicroChip PIC processor to decode the outputs to keep the parts count down and because I had them on hand. I started by attaching wires to the circuit board in the doorbell to pick up the signals from the CD4011 and provide power to doorbell from the decoder and drivers.ModifyWireless Door Bell DecoderInside

I built the circuit on a perf board and mounted it to a piece of angle aluminum. Every thing gets put into a circuit breaker box I stripped all the guts out of.Completed_Doorbell Function: When Front door button is pressed the siren sounds for a set time leaving the white lamp on for a bit longer. When the Back door button is pressed the Siren sounds for a set time leaving the blue light on for a bit longer.

Results: The unit has performed well since it was connected. Couple changes I would like to make. 1) Install a connector on the Doorbell and the box so that the actual doorbell can be located in a different location than the box. 2) Clean up the program so that white lamp does not flash when the back door button is held down (not been a problem so far). 3) Clean up the power supply design.

Steve Jobs 1955-2011

Wednesday we lost an Industry leader and pioneer. I fear that he may not see a pioneer of his caliber again.  From the early days of computers he defined the industry. Even with his departure he continued to be a pioneer in what ever he did. Upon his return to apple he continued to be a pioneer and boldly lead Apple from the verge of bankruptcy to a company with the a market cap greater than Exxon. He redefined music with i-tunes and the iPod. He defined what the smart phone is with the introduction of the iPhone. And created a new market with the iPad.

If the measure of a mans worth is all the lives he has touched and his deeds, then Steve Jobs was a great man. May his legacy live on.

My condolences go out to his wife, children, sisters and employees of Apple.
