FSAE ASSI

The Open Panzer Sound Card is a work in progress with the goal of bringing inexpensive, high quality, and open source sound functionality to RC models but especially to tanks using the Tank Control Board (TCB). The board is actually made up of two components. First, an off-the-shelf PJRC Teensy 3.2 is used as the onboard processor. The Teensy is then plugged into a socket on our custom carrier board that adds a Micro SD card slot (max 32 GB), an additional 16 MB of flash memory, an LM48310 2.6 watt audio amplifier, and headers for external connections.

FSAE TCM

A breadboard adapter for a ZM1042 Nixie tube. The ZM1042 has 1mm pins that plug in to a socket. This board is intended to use female D-SUB pins as a ‘socket’. These are often listed on eBay as ‘tube socket pins’.

See my web site for a complete list of all my Nixie tube adapters.

Board to facilitate intercepting signals to an Intellivision STIC chip

A simple fully integrated sensor node.

I designed the board to get experience with the ARM Cortex M0+ platform.

IMPORTANT: this board has been designed for the 2 oz service; if ordered with the standard 1 oz service, the properties of the antenna will not be as expected

For more detail please consult the git hub page of the project.

Pockells Cell diplexor

Description

Prototype PCB layout for a pager unit designed to operate on an existing WiFi infrastructure. It has a number of features designed for possible future expansion, to meet whatever requirements may arise during testing.

• OLED screen (0.96" OLED display with FPC connector, from BuyDisplay.com)
• DRV2605L haptic motor driver (and SMT haptic motor)
• ATECC508A crypto-authentication device
• Four soft-touch buttons intented for user interface operation
• Two soft-touch buttons intended for development and testing purposes
• Reset button
• JST connector for a rechargeable LiPo battery
• Micro USB connector for battery charging

NB: The ZIF connector (J1) is reversed in rev. A and requires some kind of mitigation, or an OLED module whose pin 1 is on the left-hand side. My OLED module’s pin 30 is on the left; there may be others that are not like this.

Micro Relay Board

I designed this to use a small signal relay () with a small package to use in many of my projects that need a relay without a log of space available. The silkscreen for the relay contacts are reversed and haven t had the motivation to update it as I am probably going to be the only person using it, but just in case I wanted any else to be aware of that. The board uses a sot-23 diode as a flyback diode across the relay coil, and it is input signal is active high which drives a transistor to pull the relay to ground. So the signal input does not directly drive the relay because that might pull more current than a microcontroller can provide from a single pin. The two pin header is there to easily check that the relay functions them out. Design is about as small as I could make so the fab costs are pretty low.
