2017-10-29 Esther Had No Fingerprints 

From FB group Bell Telephone… Speaking of federal contracts…  I had a neighbor, Esther, who was 96, and she told me about her husband’s company, Glaser engineering.  During WW 2, they were bidding on some government contract, so they had to be investigated by the FBI.  They had to have their fingerprints taken.  A few

2017-10-28 Old Telephone As Arduino Number Input

The old dial telephone uses pulses of current to dial phone numbers.  I thought it might be useful to enter digits into an Arduino.  I have to investigate if there is already a program that can do this. The phone has to have some current, maybe 10 mA, flowing through it so that the pulses

2017-10-27 Telephone To Desk Light

From FB reply to video of a European gutting a 500 style phone to make a desk light: ​The ‘giant’ (mini) toggle switch wasn’t the pain;  it was the hole drilled right through the dial that made me cringe.  I would’ve used an invention I made for a project I built.  I put the switch

From FB group Bell Telephone… Ars Technica article link at the end. Me: You’re right, Ed.  I’m also on another old timer’s group and someone brought up the days we were coming in from gym class in high school, and we had a hard time breathing because of the smog here in the LA basin.

2017-10-24 AT&T And The Breakup

From FB group Bell Telephone…  Oct 29, 30 to Ronald Cooper Yeah, Touchtone is an excellent example of AT&T’s holding back technology.  Besides the customer paying them for a service that benefitted AT&T more, making the customer pay so much ($1.20 a month, when my phone bill was $10 to $15 a month), they gave

2017-10-22 Royal 500 Battery Holder Contacts 

Here’s a photo of one contact I made from a tin can lid.  I cut it out with a scissors, and flattened and bent it with a hammer on a heavy block of steel.  It’s a bit blurry because I used a magnifying glass to get closer.

2017-10-21 Zenith Royal 500 Radio Problems

From FB group Vintage Transistor Radios Jim LaFrance: I’ve never found a Zenith that was not worthy of repair. Good solid builds! me: I agree; they’re solid, well designed radios.  Now that I have a bunch, my supply of old germanium transistors that I had accumulated seems inadequate, so I may have to start experimenting
