S-993
s-993a-desoldering-gun-looks-promising!
In this first look at the S-993A desoldering gun, it does a good job of extracting solder from some multi-pin headers and screw terminals, and it also seems to have no trouble heating up large ground planes on a video card multi layer PCB!
More testing would be needed to see how it really performs on large thermal mass boards, and the right size tips should be used for larger or smaller pins to get a better vacuum seal, but for a first try, it went well.
Here's an affiliate link to the S-993A Desoldering tool

DIGIT
digital-potentiometer-and-rotary-encoder
How to control the X9C103 digital potentiometer directly from a rotary encoder with optional switch debouncing.
If you are only controlling one digital pot at a time and don’t need to store the setting for power on recall, you can just keep chip select enabled at all times. Otherwise another modification would be required for more features but this is just a simple hack.
The rotary encoder used here has 20 positions per one revolution and the digital pot has 100 wiper positions so this is in effect, a 5 turn multiturn pot as well!
Blooper List
- I think at one point I said 500 ms when I meant 500 µs but I think that’s easy enough to catch and filter out within context.

7 SEG
7-segment-led-counter-with-7400-logic
555 Timer Dev Board giveaway winner announced!
To help select the winner, I made a 2 digit 7 segment LED display old school style on my old Jameco breadboard using a 7490 BCD decade counter, a 7447 common anode 7 segment decoder/driver, misc glue logic to customize it with extra features for the draw, and it's all clocked by the 555 dev board in astable mode.
