Amiga Video Slot AdapterThis Amiga-Digital-Video project designed by Bloodmoshert, builds on c0pperdragon's Amiga-Digital-Video project, adapted for use in big box Amiga video slots.The main differences are:The 7MHZ signal is derived via C1 XNOR C3 using an additional 74LVC86 since 7MHZ is not available directly from the video slotTwo button connectors allow for both a rear slot cover bracket button and another to be used, mounted wherever desiredThe card edge connector used is from Amiga-KiCad-Library (https://github.com/JustinBaldock/Amiga-KiCad-Library). Approximately 1mm of space is left between the fingers and the PCB edge to allow for beveling.Installation notes:Set the Denise jumper according to which Denise is in your Amiga (Super Denise for 8373, Denise for 8362)Orient the PCB such that the end with bracket mounting holes faces the rear of the machine.Software:A compatible release of the software is available from the RGBtoHDMI repositoryhttps://github.com/hoglet67/RGBtoHDMI/releases.Unzip the content of the archive to the root folder of a micro SD card, formatted as FAT32, and put in your Raspberry Pi Zero.https://github.com/c0pperdragon/Amiga-Digital-Video

This is a blast gate sensor board. This uses a 49E Hall sensor to determine if a gate is open or closed. This board is used by my dust collector monitor board. The gate's open/closed state is sent to the dust collector monitor via a CAN bus common to all of the sensor boards and the monitor.For more information see my instructable on instructables.com.

This is a dust collector monitor board. Both the dust bin level and the filter are monitored. When either needs your attention a strobe is activated and a message is sent to your FM or bluetooth capable hearing protector headphones. My earlier dust collector related board only monitored the bin level.This board is designed to work with the gate sensor board. The gate sensor boards are optional although recommended. Knowing the open/closed state of the gates allows for more accurate monitoring of the filter.For more information see my instructable on instructables.com.

Although this is board has generic application - connect any DC power supply to a voltage regulator to power and ESP8266 - we designed it to power our custom Wireless Access Point.When added to this PCB and loaded with the appropriate software, an ESP8266 can act as a Wireless Access Point that enables you to configure printerX's web server to connect to your home WiFi network.More information, including Open Source software, will be available at ostmoxy.com

An ESP32 module comes with a lot of different features. One of such features is it’s touch capability. In fact it is so well, that you can use the touch functionalities, right out of the box! You just need a piece of metal wire connected to a touch pin and you are good to go. No extra hardware is required. Now, there are 10 such touch enabled GPIOs available on the ESP32 chip. Which you can use to make some amazing projects. Such as this tiny touch remote. You can use this as a mouse for your PC, a remote for your smartphone camera or even you can integrate this in your home automation system to control your smart appliances.Let’s start with designing the circuit. So this is the schematic of the project. It only consists of a few components. Besides ESP32 we have a micro USB connector along with the USB to Serial IC to program the chip. Then we have the 3.3 volt voltage regulator. A battery connector along with the charging circuit. After designing the PCB i head over to PCBway for manufacturing this PCB. After a few days I got the PCBs at my doorstep. After assembling it I connect the battery to the battery connector to see if we are able to charge the module. Which it does as intended. Next I hooked up a micro USB connector to upload a test sketch to get the touch pad readings. And the program gets uploaded successfully. So the programming circuit is also working. And if I open up the serial monitor at this point you will see that we are getting some values. When we touch a pad the value of the corresponding pin is also changed confirming that the touch pins are also working just fine.Here I have used BLE Mouse Library to control mouse movements over Bluetooth. After uploading the code open bluetooth settings and click on add new device. From there select E.S.P 32 bluetooth mouse and it will be connected and now we can use this module as a wireless mouse emulator to make mouse movements using the touchpads. We can also use it to communicate with other E.S.P 32 boards to for example turn on and off a light bulb or dim it’s brightness. Therefore you can do a lot of things with it.

REX 9628 Extern Kernel 8The former company Rex Datentechnik was a manufacturer of many hardware in the 80s. Especially for the Commodore 64 there was a rich offer of the most different expansions. One of these cards was the Rex 9628, a board for the expansion port of the C64. The card could hold two EPROMs from 8 to 64KByte. That alone was nothing special, there were already a countless number of them from the most different manufacturers at that time.The practical thing about this card was that it could hold up to 8 kernel ROMs, up to 4 each in a 27C256 EPROM, and two of them could be plugged onto the board. For this the case of the C64 did not have to be opened. So it was possible to use another kernel externally without any intervention. There were many different kernels available in the 80's, for example SpeedDOS and JiffyDOS.ManualEXTERNAL KERNAL 8 9628On this board, "EXTERNAL KERNAL 8", can accommodate up to 8 kernals operated (2x8 to 32K Eproms). 100% compatible e.g. to all speeders like Speeddos, Rex-DOS, Prologic-DOS etc... Suitable for all 64's, also that of ALDI. Board is at the expansion port operated.You can use 1 x 2764 or 27128 or 27256 per socket. From each EPROM is addressed in each case the corresponding 8K range.About the two DIL switches, the respective eighth and slot 1 and 2 are addressed.The 4-pin DIL switch:Switch 1 2 3 4 Slot 1 Slot 2 ====================================================== on off on off 2764 2764 on off on off 27128 27128 off on off on 27256 27256 on off off on 2764/128 27256 off on on off 27256 2764/128 The 10-pin DIL switch:Switch (on) slot kernal number on EPROM ==================================================== 1 1 1 2-1 1 2 3-2-1 1 3 4-3-2-1 1 4 5-4-3-2-1 2 1 6-5-4-3-2-1 2 2 7-6-5-4-3-2-1 2 3 8-7-6-5-4-3-2-1 2 4 9 turns Game Stop on or off 10 turns the card on or off If nothing else is set, the card automatically jumps to the 1st kernal in the 1st slot.If used EPROM is bigger than 8K, ie. 27128 or 27256, then kernals must be burned one after the other in 8K blocks each. See the following address table: Kernal addresses 27128 addresses 27256 ===================================================== 1 0000 - 1FFF 0000 - 1FFF 2 2000 - 3FFF 2000 - 3FFF 3 4000 - 5FFF 4 6000 - 7FFF The EPROMs must match the notch of the socket when plugged in.https://github.com/DL2DW/REX_9628_Extern_Kernel_8/blob/main/Images/REX9628.jpg

IC TA7640 bisa kita ganti dengan IC yang sama persis spesifikasinya yaitu KIA6040 buatan Korea.Indikator Sinyal meter tidak Penulis gunakan untuk kali ini, hanya indikator LED saja yang Penulis gunakan. Kemudian untuk squelch processornya, Penulis menggunakan LDR (Light Dependent Resistor) yang bisa kita atur kepekaannya untuk fungsi pembukaan squelch. LED indikator kita letakkan berhadap-hadapan dengan LDR, sehingga terang atau redupnya LED kita gunakan untuk men-drive audio amplifier.
