  • WiFi: Odd you say that, My Pi400 detected both the 2.4 and 5 GHz WiFi out of the box and synced right up after installing the password. I moved the PI out to my mad scientist lair and hamshack and it still works fine. I did have problems keeping my BT Mouse connected to the internal BT. Keeps dropping BT signal. Had much better luck with the Logitech 2.4G wireless keyboard/mouse, not that I use that combo but was curious if it would work. I did have to ad a USB 2.0 hub but that works out OK since I also can plug in extras like a USB sound card since the built in sound socket is no longer there.... and things like that.

  • Not much other than the stated voltage range and, around 3ma up to 20ma (depending on how segments are lit) within that voltage range.

  • From the features field above: Display: Three 0.28" Red 7-Segment LEDs I'd guess that they are RED.... Anyhow, at $1.50, that's not a bad price. BUT I'd bet the postage could be a deal breaker...

    Added comment: The postage for 20 of is the same as 1... about $5. So I ordered 20. At any rate these draw about 3ma up to 20ma (depending on how many segments are lit) within that voltage range. At any working voltage, (Most LED pilot lights will draw 3 to 10ma) they seem accurate enough for most needs, will auto down range below 10 volts (2 digits after the decimal), have a mystery controller chip and from some searching, may be hackable by removing the LED assembly and adding a 3rd wire to extend/isolate the voltage range. Similar to at $8, This is a bargain!

  • I would have use for something like this IF it had a way to read out the info electronically. (say, RS232 or similar serial method) Would make a great MPPT tracking device for solar panels or tracking historical performance data of a device under test and over a long period of time without having to watch the LCD.

    Just my 2 cents worth.

  • From this page and the Arduino page: (Long story short: It's getting harder to get through hole ATmega chips and also this version has additional stuff to play with)

    "This ... version includes the new Simon Says circuit experiment found in the V3.2 SIK with all the LEDs and tactile buttons you will need to complete it, the kit also replaces the SparkFun RedBoard for the tried and true Arduino Uno..."


    "Special SMD Version: Because Atmel is moving more and more of their production capacity to surface mount ICs, the DIP packaged ATmega is becoming more and more difficult to get. To keep up with demand, we now offer the Arduino Uno R3 with an SMD ATmega. The board is identical to the PTH version of the Uno, but you won’t be able to remove the ATmega.......... "

No public wish lists :(
