Re: An idea!
开云体育I attached a picture (not sure if the forum software allows it, but let’s give it a shot). I think there was a thread on this a while ago, but basically it’s two parts. ? First, a 2000mAH LiPo battery and power/charger module and second, a Bluetooth BLE module. The power module (Adafruit PowerBoost 1000C) has a charger input (with voltage pass-through so you can use the device when charging), a JST battery connector, power switch and power output pins (in the form of a USB A footprint; no jack installed). 5V power from the power board connects to an Adafruit BlueFruit BLE module (used for Arduino projects I suspect). This module has standard serial RX/TX CTS/RTS pins. Power and serial signals are then wired to a 0.1” 1x6 Molex-style connector which then connects to header P1 on the front panel board. All of these are mounted in an insulated Altoids tin which can sit in the lid of the tin holding the Z80MC. ? I got tired of having a serial cable dangling on my desk so this makes it way easier to use. ? Rich ? -- Rich Cini ? ?

? Can we have some details here? I did this stuff back in the late 70's and early 80's, but got into appliance computers when the TRS-80 Model 1, Level 1 came out. Something about releasing the magic smoke from my Cosmac Elf. I'm pretty good with cookbooks, not so much DIY. I can build a mean PC, but that's just assembly. Any mechanic can do it.? ?

So totally portable and wireless CPM fun. ? ? Get From: [email protected] <[email protected]> on behalf of Bill in OKC too via groups.io <wmrmeyers@...> ? comatose, but probably not dead.
