Greetings. Re Digital LCD Panel Meters---Try Circuit Specialists, Inc, at HTTP://www.cir.com -- at one time they had a great selection selling for very very reasonable prices (US$10.) These days it is not really economic to construct instruments like these when commercial units are available for such a song. Note that if you wish to power your meter electronics from the same source (5V) you want to monitor then you will require a more specialised model version which allows for this, as many common meters require a power supply isolated from any input connections. Also, a lot of cheap meters are scaled for 200 mv FSR so you should know how to calculate appropriate resistive networks to allow the meter to read your range of interest.
Hope that this helps.
