  • Fixing a Clothing Rack during COVID-19 Lock-down

    Fixing a Clothing Rack during COVID-19 Lock-down

    My clothes hanging rack is broken for a bit of time has developed a crack. It’s obviously time to fix it. I already have a piece of aluminum pipe on hand that should serve as a clothes hanging pole. The only problem is that I don’t have the hardware to mount the pole to the wall, at least not easily during the COVID-19 lock-down.

    So, time to home-brew my own solution. First thing would be designing the fastening piece to attach to the wall. I measured the diameter of the pole and the diameter of the screws I have on hand, and designed this in OnShape. (model available here)

    Works great. A pretty good job given the current circumstances.

  • The Making of the Library Occupancy Estimation System, Part 5 – the Enclosure

    The Making of the Library Occupancy Estimation System, Part 5 – the Enclosure

    It’s almost time to deploy the ESP8266s. I switched from the previous board to wemos mini lite, a smaller board with a variant of ESP8266 (ESP8285). The ESP8285 includes a on-chip 1M EEPROM, reducing the cost. The most important difference is that the newer boards don’t have pre-soldered pin headers. Desoldering pins from the previous board is proven to be tedious and time-consuming.

    While waiting for the boards being shipped from China to me, I designed a enclosure for that board. I can, of course, just stick the boards to walls. But a case is always nice – it makes the project look less cheap (while it actually is pretty cheap).

    The design is consisted of 2 parts: the body and the cap. The body is going to be 3D printed while the cap is going to be cut from clear acrylic panel. 4 M1.5 screws hold the components together.

    The parts are modeled with Autodesk Fusion 360…

    and then made…

    and compared to my sketch…
