Holding things in place. What I call rope zip tie. I use paracord. Middle of cord form a 'larks head' (Bend middle then feed ends thru the loop.) keeping loop formed (or feed ends thru the larks head then tighten the larks head) wrap ends around object then feed thru the loop. Now to tighten just pulls ends in opposite directions. Careful at the step if using twine or cord with lower working load, cause can this methode and really torque down on the knot. Then just tie ends like final step of tying shoes.
If don't mind using Linux, might try using a touch screen with Raspberry Pi 3 (has wireless built in) on a VESA mount. Then using gourmet for your recipes. Bonus project, adding a bar scanner to scan in and out products as you buy and use them.
