20240201 Razor Crest Main Board PCB Revision 5

HAPPY NEW YEAR 2024

A month has passed by and before I knew it, its already February. I was quite busy with my Day Job since December and so, I had to put a lot of things away for obvious reasons. I was hoping to start with calculating and planning for the production of the Razor Crest circuit boards. It’s a great challenge due to the cost of getting the components especially the microcontroller. Moreover, I have yet to start on the assembly manual as well.

ANOTHER REVISION

Just yesterday, while I was staring at the version 04B board, I realised that I have made another mistake. The KF141 Series connectors were not the ideal solution, which got me to switching over to the 2.54mm screw in terminals instead. As they both uses the 2.54mm pitch, both connectors are basically interchangeable, even electrically. As I started to clean the design up for actual production, I realised that I the wiring for the Ramp Door, extra Ramp LED and also, the Power In were all using various solutions to connect to the PCB. And so, by moving the 10-pin connector, there is still enough space for another 6-pin connector. Once that is done, the board is now utilises screw in and no more plugging in, soldering, etc.

Which also means another re-design of the PCB (sigh), making it version 05. And with the Chinese New Year just around the corner (next Weekend), the board will most probably arrive after two weeks. By changing all the connectors, the user now does not need a soldering iron but a very small 1.5mm flat head screwdriver to connect the board.

The earlier 2.54mm KF141 series connectors was a failure. The orange tabs weakens very quickly and some failed before I could slide in the first wire.

This is version 04 where I was using both the 6-pin and 10-pin KF141 series connectors. They do look good and (supposedly) does not need any tools to connect the wires to. It is actually a pain where you need to insert 6 wires together simultaneously and also, (sometimes) the wire can be a bit loose.

This is version 05 where all the connectors are screw terminals. Same board, except I extended it by 0.5mm for the text on the right.
This is how the board looked and I have to remember the board’s thickness to be 1mm due to the lens height of the four 2mm warm white LEDs which will light up the centre corridor, labelled LED1 to LED 4.

WHEN WILL THIS COME OUT?

To be honest, I wanted it to come out since last year because as of this year, we will be having some serious changes in the Family and might be moving too. So, yeah, things are not going exactly as planned.

AND THEN COMES THE PLATINUM EDITION

Yeah, you heard that. The latest model kit now comes with some photo-etch set and also, resin parts. So, I would need to get a copy of this so I can determine which SMD LED can fit on the resin door (you know, the one with three lighted up holes at the top).

The Revell.de Razor Crest Platinum Edition No. 06788 and retails for USD149.47 (MYR704.70 Holy shiet)
