I like to sleep in late just like everyone else, but lately, I have been trying to get on an earlier morning schedule. This involved multiple alarms like 5 or 6 that I would have to dismiss every morning. So I thought wouldn’t it be great to have a button on my nightstand to turn… Continue reading Bluetooth Snooze Button for iPhone
I have always been impressed by the art of street photography. Where the photographer is right in the action of others' daily lives, strangers in passing and capturing that decisive moment. Ever since I got my first rangefinder (not necessary for street photography) I have wanted to try my hand at capturing these fleeting moments.… Continue reading Making a Radar Zone Focus Device for Better Street Photography
The Hackaday Supercon conference is an amazing convergence of electronics, makers, engineers, designers, educators, and anyone else interested in making cool projects. Each year we descend on the town of Old Pasadena to Hack on things over the weekend in early November. The amazing thing about the conference is that every year they build a… Continue reading Tayloe Mixer Frontend for the Supercon 2023 Vector Scope Badge
The Wi-Fi Coconut is a device produced by Hak5 with the express purpose of capturing all 14 Wi-Fi channels. https://shop.hak5.org/products/wifi-coconut It does this by having a dedicated Wi-Fi chip for each channel ganging all of them up via USB to a host computer. This can take quite a bit of power so there is an… Continue reading Setting up the Hak5 Wifi Coconut
The ClockworkPi uConsole is one of the most polished handheld raspberry pi computers on the market. From its metal shell to the driver software it just works right out of the box. Well after you assemble it first! https://www.youtube.com/watch?v=95cCjfx3EHw I recorded a quick video of the process and was surprised at how well everything went… Continue reading Building the ClockworkPi uConsole
First, what is an ASIC? An ASIC is an Application Specific Integrated Circuit which basically means that it is an Integrated Circuit on a single piece of silicon and its use is limited to a particular application or function. An example would be an ASIC to process an audio CODEC or run a specific cryptographic… Continue reading Designing My Very Own ASIC with Tiny Tapeout
Taking pictures and geeking out over cameras was one of my first hobbies starting with an old Olympus point and shoot, I then moved up to a DSLR upgrading as new and exciting technology became accessible to my summer job budget. I then got the opportunity to buy a Leica M8 and was immediately hooked… Continue reading Pieca: A Raspberry Pi Camera System for Leica M Mount Lenses
Portable projects require some kind of battery, but getting information on the voltage level or how much battery life you have left is a whole other problem. This can be solved by monitoring the voltage on the battery using an analog to digital converter, and then some firmware to read that digital value and produce… Continue reading Quick and Dirty ATTiny85 LiPO Battery Gauge
I became really interested in the capabilities of the nRF24L01 radio modules due to their insanely low price ~$2 in quantity, compared to something like a LoRa module ~$25. So you can basically have 10 for the price of one. Now I am not saying these are comparable devices, since the LoRa devices can be… Continue reading Measuring the Range of nRF24L01 Modules with CircuitPython
A Vector Network Analyzer (VNA) is an important test and measurement tool for RF electronics. It is capable of measuring both transmission and reflection of an electronic network. An electronic network is just a connection of electrical components, such as resistors, inductors, and capacitors, etc. This is not to be confused with an IP network… Continue reading The Amazing NanoVNA V2
