ErgoDox wireless from SliceMK (https://www.slicemk.com/pages/ergodox-wireless) is my suggestion. My current daily driver is a ErgoDox Wireless Lite – been using it for about 10 months now. The guy behind it (series of wireless ErgoDox variants) is very helpful with problems on his discord. He also has a webUI configurator that works reasonably well (which I don’t use because I prefer to keep my configs in git).
A quick duck search pointed me at https://toolsweek.com/how-to-test-a-diode-with-a-multimeter/ . It’s been a long time since I needed to test diodes, but the instructions seem to match what I’ve done before.
I’ve been mostly using TRUE LEMON, LIME, and ORANGE packets with the carbonated water. I have a 32oz insulated vacuum bottle that I use with 4 packets. It’s way more flavorful, but it’s easy to adjust the amount of flavor to water with the packets. I’ve also bought Mio flavors, but controlling the amount of flavor is a bit harder.
I shop there weekly. There’s at least 10 of them within 5 miles of where I live, including the 3 in Salem, NH that’s within 2 miles of each other on the same road.
And to be sorta on-topic, I like Polar’s flavors the best, of the ones that are easily available in this area of the state. But when the pandemic hit, I started using a Sodastream Fizzi One Touch, which significantly cut down on the amount of seltzer 12-packs I’d buy. Even with the swapping of CO2 canisters with Sodasense, it’s cheaper with the Sodastream.
They use those orange signs to indicate a sale or a special price. Also, the aisle sign matches what they use. And I recognize the labels on the house brand of seltzer that’s to the far left of the Polar bottles.
Ah. Market Basket.
SliceMK has an ErgoDox variant that is wireless and low-profile using choc v1 switches. Disclaimer: I’ve been daily-driving one of their ErgoDox Wireless Lite keyboards for about 9 months. But I like the ErgoDox physical layout – been using one on a nearly daily basis for the past 9 years.
