JDM Programmer won't work with 8 pin chips

I bought a JDM programmer from ebay. It has slots for 8 pin, 18 pin and 28 pin chips. It's not a professional model, it's probably home made. When I use Winpic800 in Windows XP SP3 it is able to successfully read and write to both the 18 and 28 pin chips without a problem, but not with 8 pin chips. They're not automatically detected like the other chips nor can they be read of programmed properly. I think it might be due to power , but I'm on a desktop PC, so I don't think it's providing less power than required, plus why would 18 and 28 pin chips work all right. It could be the programmer, but all the connections appear sound, plus the thing came with some smart cards that already contained pre-programmed chips, including two 8 pin chips, so you'd think that it must've worked at some point. As it stands I haven't got a clue what I'm doing wrong and I would really appreciate help with this. Thanks :)

Copy a eprom

Hello Is it possible to copy a eprom?

Posted by Popstickal 8 years ago


Hi Sorry for the bad English, hope you understand what I'm after. I've been searching the site for a kit that memorizes. Lets say you got 12 different buttons and 3 tactical buttons, when I push First Tactical for, lets say 3 sec. it goes into "write" mode, and now I make a combination of pushes on the 12 buttons, when done press the tactical again and now the combination is stored. And repeat with the remaining two tactical. Now I got 3 Tactical with different press Combo's.  When I'm in need of combo N#1 I just press the Tactical N#1 and it does the combo I've saved before. And so one if I'm in need of saved Combo's on N#2 and N#3. There should be a LED that tells me when I'm in "write" mode. Hope its not to confusing to understand, Its for my disabled little brother and are gonna be a great help for him and us. I will go in to further details if anybody has an idea on how to realize the setup Tnx in advance Best Regards Henrik Andersen

Help with old parts identification

I need some help identifying some old parts... Google didn't find anything that I could tell. They are: 1) AMI 8029vi C11262 (Some sort of old dip style IC chip) 2) DIS1283 8004 (This is some type of display but I can't seem to find anything on it. Wanted to see if I could hook it to an Arduino??) Thanks for any help. Mike C.

How a CPU is born

    While doing some research, I saw a link that said "How CPUs Are Made: From Sand to Silicon". Mildly intrigued and not knowing anything about how they are made, I clicked and went to the page and read.     The article briefly runs through a highly abridged series of steps in the making of what eventually turns out to be an Intel i7 processor. It starts off with the raw materials (SiO2, e.g., sand) and how they turn it into monstrous (about 220 pounds!), essentially pure, silicon ingots from which wafers are made. and many steps later the processors are boxed up and ready for store shelves.

Man injects himself with computer virus?

It may seem strange, but a scientist has implanted an ID chip with a computer virus inside it into his body so that whenever he passes an ID scanner, the virus will copy itself onto the scanner and spread throughout the system. It was made to prove a point that if somebody were to create a virus for the ID chipping system, it would be easy and could kill somebody if they had, for example, a pacemaker. A scary thought!

Solid State Sensors? (Very Edited)

What properties of an environment can be measured with solid state sensors? Specifically, I am thinking of a project requiring a suite of sensors-on-chips that can measure their immediate (dry) environment and pass the data to a control unit.So far, I know of temperature, magnetism, radiation, acceleration and light (a camera chip).Are there any other (reasonably priced) solid state sensors, and where could I find them (either new, or reclaimed from something else)Edited:OK, so I thought I could be vague about my questions and then surprise everybody with a working satellite.Turns out I'm not so clever as I thought.I'm trying to recreate Sputnik on a tiny budget. Something that could be made by Joe Public, without having to rely on grants or Lottery funding.Sputnik weighed nearly as much as I do, but all it did was measure temperature and pressure, then send beeps that changed if the temperature or pressure went outside a certain range. I know it has been outdone by students with CubeSats, but they still cost tens of thousands of dollars.I thought that it should be possible to recreate (and out-do) Sputnik's capabilities on a single board, a simple programmable control chip taking in the data from a set of sensor-chips encoding it somehow, then passing it to a transmitter to be beamed to Earth.I thought - still thinking micro-budget - that the whole thing could be cased in a short piece of sealed PVC tubing, since PVC is radio-transparent.In my head, in fact, the satellite looks like a relay baton, but shorter.Am I being stupidly optimistic?

Looking for help to change songs in Fisher Price Music box Record Player 2010

Hi there. I'm interested in seeing if anyone knows if it's possible and considerably easy to change the songs that the Fisher Price Music Box Record Player plays. This is NOT the original version with an actual music box in it. This is 2010 version which has some sort of sound chip in it. We have opened it up and it seems like you should be able to just replace the chip that has the music on it but we have no idea how to do that. Just curious if anyone has any ideas! Any help would be greatly appreciated! Thanks in advance!

Snap Circuits IC's, can I get the same functions in a small IC?

Hi. My kid (and I) have recently started messing around with Snap Circuits. We have a specific project in mind and want to design the circuit using Snap Circuits, then shrink it to fit in an Altoids box. Question: Is there a direct facsimile available of the integrated chips in the Snap Circuits box? Meaning, the same input voltage and current, where I can assemble all the matching components to my Snap Circuits circuit (switches, resistors, capacitors), and then just switch in the new (small) IC for where the Snap Circuits IC goes. This would also help with troubleshooting. Any thoughts? Here is the Elenco supplied schematic description of the Snap Circuits' IC:

Getting started with PIC's, what do I get?

Hi, I have been fiddling with Arduinos for quite a while now, I would like to get some PICs, because they are WAY cheaper, and you have to do more to get them to work, not just plug 'n play. I am going to get 2 free sample 16f648a's from MicroChip for an 8x8 matrix game like this one:  any suggestions for other PICs to get from MicroChip? Also, what is a good cheap programmer, or one I could build? Thanks a lot, Geek P.S. I am pretty good at soldering and electronics, so if anyone has ideas of other fun projects that would be cool.

Need old Microprocessor CPU chips

I need a bunch of old CPU microprocessor chips for a craft project.  They can be totally non-functional.  I'm interested in the physical package, not working electronics.  I'll pay postage and agree upon a sales price. However, I'm most interested in older chips, the 486's and early Pentiums (586's).  See figure 2 as a guideline.  I need a bunch ( > 30) but I'll buy them one at a time if necessary. All are for an Instructable, so it's for a good cause.  Any advice for websites that are selling to old chips would also be appreciated. Thanks for any help!

Wireless charging of smartphones anywhere within a 30 foot radius, without-pad !

Just read there is a 10W transmitter IC that has been developed to power a receiver IC collecting 6W of that energy... Both are ASIC chips that can operate and power power mobile devices up to 30 feet apart. Even though the RF energy is deemed safe. I would plan on using a Faraday helmet and maybe lead under wear when next I visit a coffey house.

Switching voltage inputs with a chip

I have a small project I'm working on that uses rechargeable batteries.  However I want the device to stop drawing from the batteries whenever an external power source is plugged in.  (The external power source would then power the internal battery charger and the main device.)  Is there a chip or circuit that could be used for this?  My only alternative is to modify the power supply port to include a micro spdt that will switch when plugged in.  But I'd rather like to avoid that.

Arduino VS. OOPIC

Recently I have been seeing a lot of hype about the Arduino. But whatever happened to the OOPIC? I have an OOPIC and I love it! It has got to be the best microcontroller I have ever used. But am I using something outdated? Is it obsolete? What is the big deal about the Arduino? It seems I never here OOPIC any more. So if anyone can answer my questions, or at least tell me why everyone is using the Arduino, it would help me out. I guess I don't get the concept of the Arduino.

555 TImer/Chip Help

I need your help people of Insturctables. I am working on an project, and I need to make a circuit whit a 555 timer/chip so that it makes,for example, an LED light up in every 2 second. I mean when it turns on, it needs to be on for 2seconds than off for 2 second...loop. ON(2 seconds)___OFF(2 seconds)___ON(2 seconds)___OFF(2 seconds)___LOOP I need the output to be 12V. Actually I need it for a fan to turn on and off(the fan runs on 12 volts) Can you help me make a circuit for this, what value of the resistors and capacitors do I need... It would be grate if some one could make a schematic of the circuit in Eagle, or so... If I make an Instructables about my project I will surely mention who helped me realize my idea!

Would this require Programming?

Hi! I'm building a laptop bag alarm for a project I'm working on, and I'm pretty new to electronics. Would anyone know how I could make a system where a switch would be flipped to turn 'the alarm' on or off, and when that switch is flipped, the system would do nothing when the security system is triggered. The security system being 3-8 LDR sensors inside the bag, that will trigger some sort of logical part, that would be able to make the decision whether or not to sound the alarm, based on the status of the switch (flipped or normal)  I'm a programmer, so the system looks like this to me:  IF ALARM_SWITCH_ON && LDR_TRIGGERED { TRIGGER LIGHT && SOUND }  IF ALARM_SWITCH_OFF && LDR_TRIGGERED { DO NOTHING }  ELSE { DO NOTHING } Anyone know how this could be made with circuitry? or whether it would require programming? If it required all circuitry, is there anywhere I could get help with drawing up a circuit diagram?  Cheers & Thanks!  Karan

Gameboy Color cart opened, chips removed. Wondering if anyone has specs for them?

I decided that I should do something with some of those old Gameboy Color games I had lying around, so I opened one. Inside, I found 4 chips, along with a 3v battery, a tilt sensor, and various capacitors and resistors. I was wondering what each of the chips do, as far as their use. And could I use them again for a different purpose? Here are the chips: *Small 8DIL with the Microchip logo, and 106 134A *Square chip with 8 pins on each side(32 in total), M8C3 -2 047U3E *Thin rectangular with 22 pins on both sides(44 in total), MX E012304-M MX23C1603-12A 1C9868A1 *28 pin rectangular, BSI BS62LV256SC-70 S2827V53114.N F0110 Taiwan(Obviously that means it was made in Taiwan) Just a quick check to see if anyone knew what any of these were. Thank you!

Cat chip logger

Could you modify the reader in a chip reading cat flap to log the details of the chips t hat pass through it rather than only let recognized chips open the flap? Chip reading cat flaps exist data logging is possible this I know, how to tie the two together is beyond me. Give me detailed instructions I could do it, but I'm more at home with working out how to wind the detector coil than what to do with it. The reason is this My sister has a problem, she is in danger of becoming a cat lady, or at least over run with strays or other peoples cats. Her current plan other than catching the visitors that are clearly street cats and delivering them to the local shelter, is setting a camera trap aimed at her cat flap and posting the visitor photos on the local area FB page with is this your lost cat under it.  couple of the poor conditioned strays she has managed to get to the shelter have been chipped it is  reasonable to assume that some of the others must be to, and they would be easier to catch possibly if their  owners were trying to do it. Even a simpler system that just connected chipped cat with photo, and there by identified which cats aren't chipped so presumably are true strays not just nominally owned would b of help those could then be targeted for capture and re homing first.
