Hard Disk Sound Emulator for BlueSCSI V2 (50-pin Desktop, rev. 2023.10a)

This clicker module recreates authentic vintage hard disk sounds based on HDD LED activity.
It restores the nostalgic clicking noises of classic hard drives while using a modern BlueSCSI device.

Features & Included:

- QWIIC cable included - Requires minor soldering (soldering a 3-pin header to the BlueSCSI LED header) - On/Off control header - LED passthrough support, allowing simultaneous use with an activity LED - Optional 2.7–5.5 V external power header, allowing standalone use without a BlueSCSI device

Perfect for restoring the authentic sound experience in vintage Macintosh and other SCSI-based systems.

Macintosh Battery Socket v2 (128k/512k/Plus)

daanvdl — Sat, 17 Feb 2024 15:36:26 +0000

Many Macintosh 128k/512k/Plus battery sockets are damaged or corroded due to battery leakage in the past.
This is a drop-in replacement for the Macintosh 128k/512k/Plus battery socket.
Also known as part “CAPETRONIC DS 1011” and “815-0727-B”.

Improved V2 revision – more efficient, more flexible, and safer

The V2 revision introduces several important technical improvements over the previous version:

Approximately 25% higher efficiency, significantly reducing battery drain and extending operating life
Support for 1.2 V rechargeable batteries (NiMH) in addition to previously supported battery types
Built-in reverse-polarity protection, ensuring the circuit is protected if the battery is accidentally inserted the wrong way around

Supported battery types:

1.2 V rechargeable batteries (NiMH)
1.5 V alkaline batteries
3.7 V Li-ion 14500 cells
4.2 V fully charged Li-ion 14500 cells

These enhancements make the V2 version more energy-efficient, more versatile, and more robust for long-term use.

This product requires basic soldering experience.

Bose Cinesense

Do you have Bose Cinemate speakers? Do you wish they would just turn on automatically when you need them and turn off when you’re done. This device provides everything you need to do just that. Using it, you can create an adapter that plugs into the interface module cable and adds audio sensing capability to your Bose Cinemate speakers.

How It Works

When placed inline between the sub woofer module and the interface module, the Cinesense adapter repeatedly polls the optical audio input for a signal. When a signal is sensed, the speakers are automatically turned on. The adapter will continue to monitor the signal while the speakers are in use. Once the signal has stopped for ten seconds, the adapter will turn the speakers off.

NOTE: The adapter only looks at the optical input and will not respond to audio signals on the analog inputs. This is a potential future enhancement that can be made to the design. Also, the term “Audio Signal” here is referring to optical audio “data” which is not the same as “sound”. It’s possible for the optical audio signal to be present and silent (e.g. music player is powered on but is paused).

Aside from the new found ability to automatically turn on and off in response to the audio signal, all aspects of the speakers are the same. You can still use your remote to control the volume and mute the speakers. You can even use your remote to turn the speakers off, though if there is an audio signal present, they’ll just turn right back on again.

This project only works with Bose Cinemate Series II speakers. Since the Cinemate Series I speakers don’t have an optical audio input, the Cinesense will not work with them.

Battery Converter (CR2032 -> 1/2AA)

daanvdl — Sat, 08 Apr 2023 08:34:40 +0000

This is intended to slot in vertically into a 1/2AA battery holder seen on many Macintosh computers for the PRAM battery. It will allow the use of the less expensive, easier to find and less leaky CR2032 coin batteries.

4164,41256,4116,4532 DRAM tester

daanvdl — Thu, 23 Mar 2023 18:27:24 +0000

This tester supports the following DRAM types:

- 4116

- 4532

- 4164

- 4264

- 41256

The DRAM chips are widely used in Commodore 64, Apple II, Macintosh 128k, Macintosh 512k.

If the setting is on 4164-256 it is possible to select the type of memory (from 4164,41256,4532-L,4532-H) by briefly pressing the select / start key. (memory 4116 has no selections) To start the test, keep the select / start key pressed for 1 sec. After the test the result will be displayed, if there is an error the test will stop and the point of the error will be shown.

AirTalk Pro

daanvdl — Sat, 11 Mar 2023 16:36:54 +0000

AirTalk is a dongle that extends a LocalTalk (or PhoneNet, or equivalent) network over WiFi.

The AirTalk has a serial port, where you can either plug in a modem cable to a single LocalTalk device (Mac, printer, router, etc) or plug a LocalTalk or PhoneNet box in to add it to the end of a whole LocalTalk network. It can either get its power from Micro USB or from an ADB passthrough.

AirTalk is intended to be user friendly and plug and play. It requires no software on your vintage Mac or LocalTalk device to use it, the Chooser extension only sets it up, so it will work with things like printers or routers as well as with Macs.

This is a fully assembled and working AirTalk for direct use!

The “AirTalk Pro” comes in a custom designed 3D printed case and a beautiful custom made acrylic cover.
All devices have been extensively tested before shipping!

The “AirTalk Pro” contains:

AirTalk Pro Device
Chooser software on floppydisk (one per order)
Reset-button tool
Optional ADB cable

8pin serial cables can be found in this web shop.
Software installation and setup can be found here: https://support.airtalk.nl/
