This log includes major upgrades included in the current system.Till now we had been using an older OS incompatible with RPi 3 since the display could have only worked with that image. Additionally it caused the trouble where the onboard or external...
7/29/2013: As I stated; been working on the cabinet for the Mirror universe project. I bought a couple of "project" Bally Star Treks from a fellow pinball collector out of Shertz a few years ago. These have been setting in storage for a while... and...
Summary about 4:00 pm, Monday, January 21, 2019 Soldering stuff together. Out of fear of destruction, this was done in steps, testing along the way. Deets First, the NodeMCU board has pin headers soldered on (or at least mine do). These aren't...
I finally make it working (at least on Windows 10). I already committed to my GitHub, so the latest code is now working! Also, I'm now understanding the way to report the correct hid event, so let me guide through. the number in parentheses corresponding...
Salicylic acid sublimes at at 76 °C. This makes it easy to vapor coat a kind of hot bed with salicylic acid. A ball pen like extruder moves then over the thin layer of salicylic acid and dispenses acetic acid/catalyst to form a layer of acetyl-salicylic...
Every week is science week at Makers Making Change. We really hopped on the science train this past week, though. A Visit from the Minister On April 12th, we were thrilled to welcome the Honourable Kirsty Duncan, Minister of Science and Minister of Sport...
CircuitVideo input comes from composite video source and works as a passthrough. I have used one male and two female connectors to make it easy to connect as a passthrough no matter what cables are available.The LM1881N video decoder chip is an interface...
I figured a way to get the full 13 bit resolution of the PWM and now I get the full value range. I figured that my timer counter being 8192 is just a shift of 13 so I can avoid overflow by not shifting up 13 and down 10 but rather just do the entire...
The World Create Day was a pretty great excuse to pair up with out semi-regular event, Super Happy Hacker House.It's an open house, where everyone can come in, bring a project, talk about things they've done, and then do some lightning talks. Sound familiar?https://www.instagram.com/p/BTJxQdnFdrS/?taken-by=vanhackspaceThe...
During the implementation, I found a missing key-feature. As proposed in the last weeks project log, I initially thought that only the calibration factors for the VRMS and IRMS calibration matter. In order to calculate the correct scaling value...
According to the wiibrew wiki the following is true.decrypted_byte = (encrypted_byte XOR table1[address%8]) + table2[address%8] if the host key is 16 zero bytes, table1[x] and table2[x] are all 0x97.So i set the key to zero and simplified my decryption...
I have a few ideas in mind how to make the algorithm to determine the dawn/duck time (don't forget this algorithm has to be lightweight enough to fit on low-power MCU), but taking a measurement in single place, fit algorithm to it and call it done is...
Let's start with the beginning. The C64 wiki says this A light pen is a pen-shaped input device which connects to a compatible computer (such as the C-64): The device contains a light sensor which, when pointed at a cathode ray tube screen,...
I've begun to prototype the rocket, and thanks to my friend Erica, I've learned that fins won't do much to stabilize the rocket in a low pressure environment. That being said, the two options of stabilizing the rocket are a computer-controlled nozzle...
90% of this project, I've gone ahead with hand tools or a soldering iron and just built stuff. Very little drawing out of stuff beforehand. That's my dayjob, planning ahead isn't fun.So far the damage on this project has been two blown caps that I've...
