Prepare the adapters and connect them to the terminal stripsThis part is important and tricky, and it took me three attempts to get this right. Here's the rules: Any high-current line must be a twin line that starts as a twin at the power supply's PCB...
Required Components:The component list for this computer is fairly low as only a single IC is required: 1 x ATmega 1284P Microcontroller 1 x DIL 40 Pin 0.6" IC Holder 1 x 40 Pin Female Pin Header (to be cut down into smaller headers) 1 x 16 MHz Crystal...
The Circuit:I designed the circuit diagram in the program Fritzing as it had all the required footprints readily available. The circuit is fairly simple as the ATmega 1284P has the minimum hardware connections required (along with a 16MHz crystal) to...
The PCB:Once I had used the program Fritzing to design the PCB, it was sent off to a PCB manufacture to be produced using the isolation milling process. The PCB is single sided as a double sided PCB was not needed, due to the fairly low component count...
Completed PCB: Once I had all the components and had received the PCB, I assembled it and carried out some basic multimeter tests ensuring no short circuits were present (mainly ensuring no pins had shorts to the ground plane). No issues were present...
Prepare clock2a. Drill 6mm hole in Deltron 479-0160 enclosure2b. Super glue 3xAA battery golder into the enclosure2c. solder 3.5mm jack to wires and connector, heatsrink it2d. prepare PCB2e. populate PCB2f. Super glue PmodGPS module into the enclosure(note:...
The Prototype is built using a standard-sized 160mmx100mm breadboard, It basically combines three modules. The XportPro, the STM8S105 uC and the VS1053 (the final device will utilize an VS1063)The STM8S105 comes premounted on the pcb of the STM8S-Discovery...
Obtain or produce the sub assemblies pictures above (See github for detailed assembly instructions, gerbers, and STLs): Polycarbonate front cover. Encoder PCB, Top housing, LCD, Knob, Main PCB, Paddles, Battery, Bottom Housing, screws and washers.
LoFi is expected to be delivered ready-to-use (prepopulated and preprogrammed). These instructions are for people that want to build LoFi themselves from scratch or are interested for curiosity. These instructions are expected to change as the project...
Open the PCB layout folder and locate desired PCB you'd like to have made. For example, LoFi-PCB-Layouts/Sender/LoFi-Sender-v7.zip. Drag that zip file onto the OSH Park web page to upload it.
