I want to share with you this is little rework station that I have built out of frustration, after consecutive failures in the available affordable options (853d+, 909d)
Objectives:- affordable (keep below 50$ excluding the enclosure and shipping)
- reliable
- maintainable
- open sourced
- modular (3 modules: controller - interface - 24V AC/DC converter)
the features list so far- fast rise time.
- USB and Bluetooth connectivity.
- programmable (heat profile of various ICs)
- easy to calibrate with low cost thermometer.
- buzzer for notifications.
- 240x320 2.4" Color LCD display.
- G16 8Pins connector socket for the heat gun.
- firmware safety features:
- system level auto-sleep after a certain user defined time. (wakes up upon any interaction with the front panel user interface)
- the heat is switched off after a certain user defined time. (set as a precaution measure against forgetting the unit running when heat is switched ON)
- optional audible 500ms beep every 60 seconds when the heat is ON (works as a reminder/notifier before the previous feature kicks in)
Enclosure- currently 3D Printed, PLA treated with fire retardants (just in case).
- eventually will be upgrade a tin or aluminum enclosure.
- planning to add a sort of a bracket to which the airgun can be attached over the pcb
Front Panel:- currently 3D printed, I think will keep the same design if upgrading to a tin or metal enclosure.
Firmware Com Protocol over Bluetooh:Status:I have been using the original prototype almost daily in the last year and half.
added the bluetooth communication feature in the second iteration.
To note that i have used the MSP430G2553IPW20R as the main uC on both the interface and the controller boards.
