Log from Open Indirect Ophthalmoscope
Earlier version of the device was reconsidered in terms of following aspects:• Accommodating for different refractive errors • Aesthetics • Ergonomics • Weight distribution OIO ASSEMBLY EXPLODED ASSEMBLY1. ACCOMMODATING FOR DIFFERENT REFRACTIVE ERRORS...

Finally getting to the heart of merge sorting
Log from YAMS Yet Another Merge Sort
The last log has shown the results of the latest development work, which ensures that input data are correctly pre-sorted into ascending runs as they arrive, at the cost of more than doubling the working area (which is not surprising for a merge sort)....

Penultimate steps
Log from Симон
Right now the prototype suffers from two distinct problems. One is that there's some crosstalk of the LED rastering on the audio. That I believe I can solve by simply routing the audio line so that it doesn't cross under any of the raster lines. The...

UPS-18650-NS Installed on the seismometer
Log from Single-cell Li-Ion Powered UPS for Raspberry Pi
The UPS-18650-NS is installed and working on my seismometer (I think.) The Raspberry Pi version that services the seismometer is a B+. The only way to know if it is working for sure is to disconnect power and wait 4-5 hours. Here's a photo of the installation:I...

Onward toward manufacturing
Log from Solar MPPT Charger for 24/7 "IOT" devices
Got the manufacturing test fixture designed, boards back and built. Now to write code. The test fixture will program code into the on-board micro (actually program two programs, the first used to find the micro's calibration value) and perform...

V2 Prototype - Battery Powered
Log from YDrip
The main goal for V2 was making it battery powered which turned out to be extremely difficult. First, the PCB and case was expanded to make room for three AA batteries.Then I started replacing/adding a few components: RT9080-33GJ5 regulator due to its...

Reliable, 5-fingered readability
Log from Sotto: A Silent One-Handed Modular Keyset
Here's a super hacky wire/conductive pad version of Sotto:Each finger pad is soft and not too noticeable, and also highly reliable and subtle. Plus, it's cheap and easy to make! Super excited to design a good enclosure here that is going to make it easy...

Log from PSION II Datapak and Rampak Reader/Writer
Andrew Menadue has created a PCB for a datapak-tool to read & write to Organiser datapaks. It features an on-board SD card reader, display and control buttons. The board uses a Raspberry Pi Pico for the datapak IO and includes a boost circuit to supply...

More Problems with the LTC4041 version
Log from Single SuperCapacitor UPS for Raspberry Pi
I installed the modified UPS board, and 100F supercap, into my heating system. It did not go well. The UPS would power the Pi and peripherals the first time that it was plugged in, but it would not apply power after a disconnection. I found two major...

Pulser with ADCMP606
Log from The Rise and Fall of Pulses
I figured for a first try, I'd use a $6 ADCMP606 CML-output comparator. It's not the fastest available, with leisurely 160 ps typical Tr/Tf, and 1.2 ns minimum pulse width. There are faster ones available, like the $70 HMC874, with 24 ps rise and 15...

We sent uECGs to backers! (and some other January news)
Log from uECG - small open source wireless ECG sensor
We've not written anything for a whole month! But we have been far from idle. First of all, we just sent all of the uECGs to Indiegogo backers (finally!). That brought closure to a large period in our lives and we're really happy that we did it. ...

Manufacturing
Log from Knobo
While I may be a high schooler, I'm no stranger to bringing products from prototype to production, which is proven by the two successful Kickstarter campaigns I ran for my other products. For Knobo, the electronics will be manufactured overseas while...
