# RFID Logger Enclosure | ||
|
||
This project is extremely easy to house in an enclosure. There are no buttons, no moving parts, no display! | ||
|
||
Often the hard part for the DIY maker is getting USB power to to board inside the enclosure. One method | ||
is to perfectly mount the board near the perimeter of the box. Then, use a drill or dremmel tool to cut | ||
a nice, perfectly shaped USB connector hole. Easier said than done. | ||
|
||
One possibility is to 3D print an enclosure. Not everyone has accecss to a 3D print | ||
|
||
An alternative method is to drill a hole at seam between the lid and the box. For best results, have the lid | ||
snuggly secured when drilling: | ||
|
||

|
||
With just-the-right-size bit (typically 1/8") - this will allow the USB housing to be used as a strain relief: | ||

|
||
As half of the hol is in the base, and the other it in in lid, cable insertion is quite easy: | ||

|
||
USB cables come in different size diameters, to it is best to measure to get a nice tight fit. | ||
|
||
For long term durability it is best to get boards withouot headers already soldered, | ||
and solder the wires directly to the board. In for prototypes, it is usually best to use jumper wires. | ||
|
||
Here's a closeup of jumper wires connected to the RFID Reader Board: | ||

||
Note that for maximum range, the RFID PCB with the printing should be as close to the swipe seruface as possible. | ||
The side with the printing is the side with the copper traces as an antenna. It will work from either side, but | ||
might as well do everything possible for best range. | ||
