Cart for growing lettuce. It sets right outside the back door. Come dinner time the wife just goes out and picks enough for two bowls. Nothing like fresh picked lettuce to go with a meal.

This is a Fox Hunt Transmitter that I created using a lot of inspiration from this video https://tinyurl.com/yw2drf66 that was created from information the Whitecourt Amateur Radio at https://wcar.ca/pg/fox-tx/ and also from this information about using a Cell Phone to transmit recorded voice https://tinyurl.com/32jsksa3.
I added an Adafruit Sound Board to the Whitecourt AR example so that Morris Code or Voice transmission can be sent.
The Arduino code that include my modifications can be seen here; https://tinyurl.com/4k8a7k5b

I think I have it narrowed down to one set of contacts in the switch. I have one more test to perform to verify that. So one more trouble shooting video to come.

Forging one of the wedges for a Lewis. A lewis is inserted into a dovetailed recess is cut into the top of the stone block (mortise). The two outer pieces of the lewis device are inserted first and then spread by the insertion of a appropriate sized centerpiece. The three parts are then bolted together, a metal ring or shackle is attached and the block is hoisted by hook, rope and pulley. By this means, the block is gripped securely and appropriately balanced. Once set in its place in the structure, the lewis is removed leaving the upper surface smooth with no clamp or chains on the outside to interfere with the laying of the adjacent or next course of stones.
Stones with the mortised cavity for the insertion of a lewis have been found in England in Hadrian's Wall built c. 121-127 CE. Archaeologists have found further evidence of its use by the Saxons in England in buildings constructed in the 7th century.
