I need things in my life that only do one thing but are crazy reliable. This is the best writing tool ever created. Distraction free, two AA batteries last weeks, and highly portable. Basically a typewriter but has USB send to a computer file when you’re ready. Straddles the technology bridge perfectly. I own two of them.
Sometimes when working on counters in Verilog, I have difficulty picking out the bit ranges I want to achieve and the scaling up and down I want. Looking at it visually and a little Julia scripting helps.
