Small, simple capacitive proximity sensor board, based on the MTCH101 proximity sensor IC. It works off of 2v to 5.5v. The MTCH101 is a proximity sensor, and it's sensitivity can be adjusted using the small potentiometer on board - with low sensitivity, it will act like a touch sensor. The output is open drain, and pullup resistor is included on board. The touch input can be connected to anything conductive. This is a major difference from most touch or proximity sensor boards available - most of them simply use a patch of copper on the board as the sensor, leaving no way to make an external connection. This greatly understates the capability of this part - you can use anything conductive. This has particular potential in electronic art and sculpture applications.
Sold assembled - just add wires (or pins) and sensor!
Note that several pictures above show more than one sensor. The price is per single sensor.
The conductive sensor can be any conductive object, but it must be electrically connected to the Sense pin on the board. The sensor can be as simple as a wire (with or without insulation), or you can use pieces of foil, screen, etc. The size of this conductor has a great impact on the sensitivity. The larger the sensor, the more sensitive it is - though very large sensors can also result in false positives. I have had good results with things ranging in size from tiny pieces of wire to soda cans. The wire between the board and the conductive material used as the sensor should be as short as possible, as it will also act as part of the sensor. For best results, take advantage of the small size of the board to place it as close to the desired sensing area as possible.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I build projects with Arduino (ATtinies almost exclusively, never anything bigger than a '328p) and Espruino (often both working together), and I make a lot of circuit boards for these projects. Particularly after using my ATtiny-prototyping board for my own projects, I realized that these would be useful to other people, and decided to start selling them here on Tindie.
Strip Board, Protoboard, prototyping board, solderable breadboard - whatever you want to call it - it has been a mainstay in electronics prototyping for decades, and hasn't changed much in the interim (not even in production quality, as they're still often single-sided and/or manufactured from low-grade phenolic resin instead of FR4). My prototyping board creations bring these into the modern era, offering a combination of 0.1" through-hole prototyping areas (consisting of groups of 2, 3 or 4 pins connected together, like solderable breadboard) and pads for common surface mount packages connected to through-holes for easy soldering. To handle projects of all sizes, I offer prototyping board as large as 4" x 4", down to less than an inch square in my Mini Protoboard line. Unlike most commercial prototyping board, these boards are made to the same quality standards as real PCBs. Through-holes are plated, and the boards are double sided. These are offered in both generic versions, and ones tailored to specific microcontrollers, like the Tiny84/85, or microcontroller boards, like the Espruino Pico, Arduino Pro Mini, and the wildly popular ESP8266.
ATtiny breakout boards:
I love the ATtiny lineup, particularly some of the less popular ones, like the incredibly full-featured ATtiny841, ATtiny1634, and ATtiny828. Breakout boards for these that had the features I wanted were not readily available - so I made my own. I've since expanded my product line to include breakout boards for the ATtiny861, ATtiny167, and ATtiny88 - and all of these are available both as bare boards and assembled. In addition to designing the hardware I also maintain [ATtinyCore Universal](https://github.com/SpenceKonde/ATTinyCore), which enables Arduino support for all these ATtiny's and more.
I also sell a number of other boards to fill what I felt were gaps in the market, including a breakout board for the popular LoRa/LoRaWAN modules from Microchip (the RN2483 and 2903), which has become one of my top selling items. I also sell MOSFET drivers and breakout boards for logic level MOSFETs operating at logic levels of 2.5v and lower - while a great number of MOSFETs are available that operate with very low gate voltages, these are almost invariably SMD parts which are difficult to use without a properly designed breakout board.
