DIY Seltzer Water

I’ve been drinking allot of seltzer recently and started looking at home-brew option on instructables.com

In the process I found a beverage distributor that sells a kit ready to go.  Homebrew drops the price from $2 to about 4 cents per 2 liter bottle.

Ten Tec 1253 – FIN

If you were listening to radio in the 1920s you were probably using a  regenerative receiver or “gennie”. The simple design made construction relatively easy and they could receive radio signals from all over the world.    The superheterodyne receiver  quickly became king in the 1930s but gennies have lived on as kits and diy projects.  I understand why, there’s something amazing about tuning in a station with this radio.  You can “hear” how the radio theory works as you tune in and jump onto a carrier frequency and listen the transmission that rides along.
 
The instruction manual is well written and pointed out the snags you find in a set of plans once you’ve  coached a few people through the build.   There were a few checkpoints to test the project along the way, the tests gave me confidence in the work I was doing.   

 

Tec Ten 1253 SW receiver parts sort

I’m impressed!  The instruction manual seems excellent, a lot of attention to detail.

I settled into part sorting and labeling,  I like to use index cards and a cigar box to keep everything organized.  I usually use a meter to sort resistors, the color bands are very hard to read.  The inductors were a little tricky.  I’m hoping to have the kit together before I go back to school in January.
