Hi! my name is Viola Leqi He, welcome to my thesis presentation. So I was born in 1996 in Shanghai, China, right here, in this area. This was me, spending a lot of my excited baby hours, running around, exploring my neighborhood. In fact, up until leaving for the US when I was 18, my … [read more]
For finals I went back to Twine to make some stuff, hoping to expand my second assignment. Together with Tinrey we found a bunch of exciting bitsy hacks, which inspired me to make a huge project that intertwine (ha!) twine and bitsy, using bitsy color, bitsy 3d, and maybe some other stuffs. This list of … [read more]
New schematic update: The device is comprised of 4 parts (from top left to lower right): an OLED screen for display, an RFM95 LoRa module, an ATMEGA 328P microcontroller connected to three buttons and two small LEDs, and a power supply regulated to 3.3v New board design: double-sided, with battery parts on the back side … [read more]
i didn’t do it. i’ll do it this weekend.
Continued working on my Lora prototype. Made a (probably inaccurate) schematic and Eagle file. I was very surprised that I managed to stuff most of it in a 12-pin chip!! Apart from 2 SPI modules, I could fit 3 buttons and 1 LED with the rest of the free pins. Designed my first double-sided board. … [read more]

You’re active on forums and fan sites and probably have more online friends than irl friends. There’s someone you’ve talked to online for a year now; you’ve gotten to know each other’s first … [read more]
This week, we were each assigned a letter for a collective Marquee Sign project (> ERROR COMPILING ). We are to use Autodesk Eagle to create circuit schematics, and turn them into PCB designs. My letter is “R”. The third R. The circuit is similar to what we made last week, with an ATTiny85, capacitive … [read more]
